A while back I posted about some issues found with SyncTERM and NetRunner (alpha) getting disconnected from ENiGMA 1/2 systems when connected over SSH. I'm hoping this report will find it's way to the right authors:
It appears the issue is indeed with keepalives: When a OpenSSH style keep alive
"ping" is sent, both clients in question respond with an error packet. The keep-alive is simply a "keepalive@openssh.com" global request which expects a reply. It has the following bytes:
// global request
80
// "keepalive@openssh.com"
0, 0, 0, 21,
107, 101, 101, 112, 97, 108, 105, 118, 101, 64, 111, 112, 101, 110, 115, 115, 104, 46, 99, 111, 109,
// Request a reply
1
As both clients share that they use Cryptlib and I have not seen this with clients that are based on other libraries, I'm tempted to believe it's a Cryptlib issue or perhaps one must enable/handle the pings manually with cryptlib?

For now, I have disabled the keep-alives, but this has drawbacks as
well: Various ISP's love to disconnect connections that are "idle" aka
not respect lower level TCP/IP flags & pings usually help with this.
I forwarded a link to your message to Deuce in irc.synchro.net, but you can also submit a feature request at https://sourceforge.net/p/syncterm/feature-requests/
I'll post this to Mystic in the hope James can see your comments. Thanks for sharing the info Nu :)
That's usually NAT timeouts causing that. Highly annoying. Another place IPv6 has the edge. :)
