  • ipv6 address bug (?)

    From Oli@2:280/464.47 to All on Thu Sep 16 09:45:22 2021
    Looks like binkd has problems parsing some IPv6 addresses correctly:

    Here I have no problem with ULA addresses:

    Note: I have the literal address in the config, no DNS incolved. So the problem may be in the DNS server.

    I also use the literal IPv6 address. I just tried it on another machine with 64-bit Linux and I cannot reproduce the problem there. Interesting. Maybe specific to 32-bit (or armv7 / Raspberry)?

    I use the 32 bit Windows version, so no 32 bit problem as such.

    Maybe...

    Correction: the IPv6 over Socks5 problem is the same on the 64-bit machine.

    Which probably mean the problem is on Socks5 server side.

    The problem with the direct connections has most likely nothing to do with binkd. After a reboot I cannot reproduce it anymore. Maybe user error.

    The problem with ipv6 and socks5 persists though. Does anyone use IPv6 addresses with socks5 successfully?

    machine.

    Which probably mean the problem is on Socks5 server side.

    The socks server only receives the first part of the IPv6 address and the port number (fd12:24554).

    This is exactly what binkd tries to do:

    16 Sep 16:55:51 [2645] trying fd12 via socks 127.0.0.1:2080...

    Looks very much like binkd cannot handle IPv6 addresses for socks5 connections. Socks server works fine with other software and IPv6.

    Indeed, that makes sense.
