Re: [lwip-users] lwIP tun ARP table
I don't know what you mean by "lwIP tun ARP table", lwIP is oblivious to tun/tap. I guess you have an lwIP port running in a Linux machine, "connected" to a tun/tap interface. If you want to see the lwIP ARP table you go one place (e.g: src/core/ipv4/etharp.c and discover the existence of static struct etharp_entry arp_table[ARP_TABLE_SIZE];), if you want to see Linux ARP table for that tun/tap interface, you go other place (e.g.: Google, and discover that if you have procfs you can grep tun0 /proc/net/arp; assuming 'tun0' is the name of the interface). ___ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
Re: [lwip-users] lwIP tun/tap
When you use the tun/tap interface in Linux, you have a tun/tap interface in Linux. Nothing from lwIPland, just Linuxland. As per my (sort of) expertise, you get what looks like another Ethernet card attached to a network. There is your plain trusty old linux machine on one side, there is your brand new process on the other side. Unless you set it in bridging mode, thing I don't know how to do (but you can ask your good friend Google), if your port process wants to connect with "the rest of the machine", you have to route; that means properly configuring routing on both ends. (I'm talking networking, not IPC) Your lwip port will have to be setup with a default gateway equal to the tun/tap address (which belongs to Linux), and be assigned a different address on the very same subnet. If you want to serve DHCP on that tun/tap, you have to configure the DHCP server to listen to that interface (and probably start it after the tun/tap goes up when you start the lwIP port). If you have a web server on lwIP and want to access it from Firefox on a Windows PC on your local network, you have to have a route to your tun/tap (or a default to your Linux) in your Windows. Your Linux machine is a router with several interfaces and one of them happens to be connected to a device that is the lwIP port process. So I guess the answer to your question is that the Linux stack will send ARP requests on that network and your lwIP port will listen to them. Just the opposite will happen when your lwIP port wants to know the MAC address of the Linux side of the connection. ___ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users

I don't know how to implement an ssh server, but using lwIP sockets, it should somehow work. I just wanted to say ssh won't be a part of lwIP.
