  +body: """
    I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
    \n
    I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
    \n
    Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
    \n
    From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
    \n
    It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
    \n
    Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
    \n
    Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

      From Wikipedia, the free encyclopedia\n
      \n
      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
      \n
      ### Rules\n
      \n
      - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
      - No misinformation\n
      - No NSFW content\n
      - No hate speech, bigotry, etc\n

    I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
    \n
    I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
    \n
    Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
    \n
    From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
    \n
    It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
    \n
    Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
    \n
    Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

    Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
    \n
    ```\n
    \n
    <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
    </span><span style="color:#323232;">wifi0 -> internet\n
    </span>\n
    ```\n
    \n
    Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
    </span>\n
    ```\n
    \n
    On your iPad, go to Settings -&gt; Ethernet:\n
    \n
    - address: 192.168.69.2\n
    - subnet mask: 255.255.255.0\n
    - router: 192.168.69.1\n
    \n
    Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
    \n
    How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">nc -l 8080\n
    </span>\n
    ```\n
    \n
    On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
    \n
    Curious to see if that all works!\n

    +url: null
    +body: """
      I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
      \n
      I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
      \n
      Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
      \n
      From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
      \n
      It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
      \n
      Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
      \n
      Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

    Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
    \n
    ```\n
    \n
    <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
    </span><span style="color:#323232;">wifi0 -> internet\n
    </span>\n
    ```\n
    \n
    Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
    </span>\n
    ```\n
    \n
    On your iPad, go to Settings -&gt; Ethernet:\n
    \n
    - address: 192.168.69.2\n
    - subnet mask: 255.255.255.0\n
    - router: 192.168.69.1\n
    \n
    Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
    \n
    How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">nc -l 8080\n
    </span>\n
    ```\n
    \n
    On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
    \n
    Curious to see if that all works!\n

      I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
      \n
      I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
      \n
      Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
      \n
      From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
      \n
      It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
      \n
      Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
      \n
      Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

    Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
    \n
    ```\n
    \n
    <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
    </span><span style="color:#323232;">wifi0 -> internet\n
    </span>\n
    ```\n
    \n
    Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
    </span>\n
    ```\n
    \n
    On your iPad, go to Settings -&gt; Ethernet:\n
    \n
    - address: 192.168.69.2\n
    - subnet mask: 255.255.255.0\n
    - router: 192.168.69.1\n
    \n
    Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
    \n
    How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">nc -l 8080\n
    </span>\n
    ```\n
    \n
    On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
    \n
    Curious to see if that all works!\n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
      \n
      I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
      \n
      Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
      \n
      From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
      \n
      It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
      \n
      Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
      \n
      Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
      \n
      I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
      \n
      Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
      \n
      From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
      \n
      It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
      \n
      Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
      \n
      Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

      Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
      \n
      ```\n
      \n
      <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
      </span><span style="color:#323232;">wifi0 -> internet\n
      </span>\n
      ```\n
      \n
      Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
      </span>\n
      ```\n
      \n
      On your iPad, go to Settings -&gt; Ethernet:\n
      \n
      - address: 192.168.69.2\n
      - subnet mask: 255.255.255.0\n
      - router: 192.168.69.1\n
      \n
      Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
      \n
      How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">nc -l 8080\n
      </span>\n
      ```\n
      \n
      On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
      \n
      Curious to see if that all works!\n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
      \n
      I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
      \n
      Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
      \n
      From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
      \n
      It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
      \n
      Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
      \n
      Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

      Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
      \n
      ```\n
      \n
      <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
      </span><span style="color:#323232;">wifi0 -> internet\n
      </span>\n
      ```\n
      \n
      Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
      </span>\n
      ```\n
      \n
      On your iPad, go to Settings -&gt; Ethernet:\n
      \n
      - address: 192.168.69.2\n
      - subnet mask: 255.255.255.0\n
      - router: 192.168.69.1\n
      \n
      Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
      \n
      How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">nc -l 8080\n
      </span>\n
      ```\n
      \n
      On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
      \n
      Curious to see if that all works!\n

      I’m trying to connect a university ipad (air, usb 3 type c, not tb or lightning) to my laptop (Framework laptop, intel 12th gen) running Fedora workstation 39. On Windows, I used a nifty app called Duet Display. I just used a usb-c cable to plug the ipad into the laptop, launched the app on both devices, and windows would see an external monitor. Scaling and resolution worked fine, and latency wasn’t perfect, but was more than enough for a secondary display. With settings tweaked, artifacting was minimal.\n
      \n
      I know there are remote desktop protocols and apps, but I really want to avoid a wireless connection. Remote desktop over the internet is wasteful and unreliable, and as for local network, ,my university has some strict controls on its wifi network and I cannot reliably connect my devices. Even if I could, the reliability and latency are still bad.\n
      \n
      Duet over usb always worked and didn’t rely on a wireless connection, but it also is closed source and windows and mac only.\n
      \n
      From what I can see online, the best way for an ipad to display content from another device is going to be a remote desktop protocol as it does not directly accept video signals like HDMI-in. The ipad can also connect to a network over usb c/ethernet.\n
      \n
      It seems the best approach would be to create a local network on my PC and connect my ipad to it with the cable, and then use a remote desktop client on the ipad.\n
      \n
      Is this a good approach? If so, how exactly would I make the usb connection share a local network connection?\n
      \n
      Note I only want to connect the ipad to the laptop. I understand if the ipad will not connect to wifi while connected to ethernet, and I don’t need to share the internet connection with the ipad. My computer still needs to be connected to wifi/ethernet to access my university network, however.

      Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
      \n
      ```\n
      \n
      <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
      </span><span style="color:#323232;">wifi0 -> internet\n
      </span>\n
      ```\n
      \n
      Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
      </span>\n
      ```\n
      \n
      On your iPad, go to Settings -&gt; Ethernet:\n
      \n
      - address: 192.168.69.2\n
      - subnet mask: 255.255.255.0\n
      - router: 192.168.69.1\n
      \n
      Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
      \n
      How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">nc -l 8080\n
      </span>\n
      ```\n
      \n
      On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
      \n
      Curious to see if that all works!\n

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

      Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, `eth0` and `wifi0`. `wifi0` is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).\n
      \n
      ```\n
      \n
      <span style="color:#323232;">iPad -> usb-c-ethernet -> eth0\n
      </span><span style="color:#323232;">wifi0 -> internet\n
      </span>\n
      ```\n
      \n
      Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">ip addr add 192.168.69.1/24 dev eth0\n
      </span>\n
      ```\n
      \n
      On your iPad, go to Settings -&gt; Ethernet:\n
      \n
      - address: 192.168.69.2\n
      - subnet mask: 255.255.255.0\n
      - router: 192.168.69.1\n
      \n
      Curious to see if that works. We haven’t set up DNS or DHCP or done any `sysctl` for IP forwarding or any nftables.\n
      \n
      How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:\n
      \n
      ```\n
      \n
      <span style="color:#323232;">nc -l 8080\n
      </span>\n
      ```\n
      \n
      On your iPad, open Safari and browse to [192.168.69.1:8080](http://192.168.69.1:8080)\n
      \n
      Curious to see if that all works!\n

    From Wikipedia, the free encyclopedia\n
    \n
    Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
    \n
    Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
    \n
    ### Rules\n
    \n
    - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
