The 4.6p1 sshd is logging this error during remote commands or file transfers: error: channel 0: chan_read_failed for istate 3 Platform is Solaris 8, 4.6p1 + OpenSSL 0.9.8d. The commands and transfers work correctly, so the error message appears to be spurious. The error message does not appear when processing logins. Otherwise 4.6p1 is running without any apparent problems. This error

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, 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

...equence. *Then* 'session_free' is called (as part of session close), and we end up back in session.c. Next (in serverloop.c) is called 'channel_after_select' which calls channel_handler. This calls (in our case we are using protocol 2) 'channel_post_open_2', which calls 'channel_handle_rfd' which (eventually) calls 'chan_read_failed' because the channel still hasn't been closed. As such in the original openssh we get the final - debug1: channel 0: read<=0 rfd 8 len 0 debug1: channel 0: read failed error: channel 0: internal error: we do not read, but chan_read_fa...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Basic context for my questions: Client (ssh) and server side (sshd) where the client use -L option for a direct-tcpip channel and forward all requests. (All Linux and openssh version 5.9p1). $ ssh -L8080:<some-ip>:8181 ... I noticed that when a third client send data to the local port (8080) used for forwarding, a channel is created:

Using OpenSSH_8.3p1 I had an open (working) connection to some other box; after a bit of inactivity, some device in the middle seems to have forgotten about the TCP connection (NAT) and broke it. I've got an EscapeChar defined, though; so first I tried to send a BREAK and, when that didn't help (TCP already gone, packets get lost!), I tried (just out of curiosity) a Rekey. Now I can see

Hi, We have upgraded the openssh 4.6P1 on Solaris 8 servers. After upgrade we get the below error message whenever we execute the remote commands using ssh. Please let me know what the fix is for this.
