Hi, How do the communication between sshd and program happens when compat20 is enabled? There are two function process_buffered_input_packets and process_input, but in both cases if compat20 is enabled its just buffering the packets, but how do sshd will the command to program for execution? Regards prasad

Hi folks, I'm currently trying to connect to version 1.2.16 of the commercial server. The server says it supports protocol version 1.4 and that that is incompatible with protocol version 1.5. Is that actually true? The complete output from "ssh -v xxxxxxx" is: $ ./ssh -v xxxxxxx SSH Version OpenSSH_2.3.0p1, protocol versions 1.5/2.0. Compiled with SSL (0x0090581f). debug:

I am running OpenSSH 2.9p1 on SunOS 5.7 w/4-24-2001 patch cluster. Like many other users I am seeing the hanging session on logout with background processes. This is a huge problem for me as I centrally manage 50+ machines with rdist across ssh. Instead of just complaining about the problem I thought I would put my CS degree to use and try to track down the problem myself. For starters,

In the changelog, there is an entry: 20001129 - (djm) Back out all the serverloop.c hacks. sshd will now hang again if there are background children with open fds. Does this mean that this is regarded as expected (and correct) behavior, that should not change in the future, or does it mean that this behavior is a known problem that someone will eventually fix? --Adam -- Adam McKenna

Hi folks, Could you tell me which function in clientloop.c is responsible for reading user keyboard input? What I found are client_make_packets_from_stdin_data() and client_process_input(), but they not for 'compat20' mode. My app runs in 'compat20'. Thanks, Bob
