similar to: FEATURE: -f -f - fork after successful open of fwd port/display/agent

Markus, How's this patch? - a chan_wont_read()/chan_wont_write() API is added that is very much like chan_read_failed()/chan_write_failed(), but for the debug messages and chan_wont_*() don't ever call error() The 3.0.2p1 channel_pre_x11_open() uses chan_*_failed() but looks like it ought to use chan_wont_*() instead :) - forkoff() no longer fakes EOF for SSHv2 (still

Please review the function below, forkoff(), meant to be used in clientloop.c instead of daemon() and the code in process_escapes(). The intention is to make ~D ( like ~& but also detach) possible and to make it possible for ssh -f (or ssh -f -f - see other thread on this) to detach, not just forkoff(). I also intend to use the same detach technique in a feature patch for the hang-on-exit

I'd like a feature whereby ssh puts itself in the background after the first successful X11 (or other port) forwarding. The reason for this is simple: error handling. If the application fails to open the X display and exits, then the client can still exit with the application's exit code. But if the application opens the X display successfully, then it can just display any errors by

Hello ! Like Edmund EVANS reported openssh-2.1.1p4 won't fork to background when using protocol 2. I managed to hack a little patch that might work ... What is the -N command line option supposed to do ? I gather it should work only with protocol2 and without any command to run on the server (and with some port forwardings ??) Anyway in the patch I put some code to check that -N is used

Hi I'm trying to wrap ssh in an application using glib. For now, I'm launching the ssh client in master mode and want it to detach, keeping the control socket around. I figured I could do that using the -f flag and the usual Control* options to force ssh to daemonize (ideally without executing any command), but it turns out that glib doesn't recognize the daemonized process as

Now that the list is said to be open again, I'm resending this. I've merged my changes into OpenSSH 2.1.0 as Kris imported it into FreeBSD over the weekend. ---------- Forwarded message ---------- Date: Thu, 4 May 2000 08:40:22 -0500 (CDT) From: Guy Helmer <ghelmer at cs.iastate.edu> To: openssh-unix-dev at mindrot.org Subject: OpenSSH (1.2.3) sshd hanging when using rsync over ssh

Hi- I applied the privsep patch to Tru64 5.1A openssh 3.4p1 and it *almost* works. I get in from the client side and xauth is run, but in the meantime the server side disconnects. Running sshd in debug mode level 3 gives the following output: . . . debug1: session_input_channel_req: session 0 req shell debug1: fd 5 setting TCP_NODELAY debug1: channel 0: rfd 13

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and slave processes and I even bothered to write it up :) It tracks the control sockets

To whomsoever it may concern, I use putty-0.51 as ssh client on windows and openssh-2.9p2 implementation on RedHat 7.0 Linux as ssh server. For the client to exit, I expected ssh client to send SSH_CMSG_EOF to the server and the server respond with SSH_CMSG_EXITSTATUS and finally close the connection when the client sends SSH_CMSG_EXIT_CONFIRMATION. This will effectively end the server_loop in

Hi, In file ssh.c, in function "ssh_session2", this piece of code: /* If requested, let ssh continue in the background. */ if (fork_after_authentication_flag) if (daemon(1, 1) < 0) fatal("daemon() failed: %.200s", strerror(errno)); implements the "-f" option, but when run from cron, it does not detach properly because of the second parameter

Hello, I am porting the Openssh3.4 code to a proprietary operating system. I am running into the issue of ssh client disconnecting with a message - Disconnecting: Bad packet length 2782384553. This happens only when there is a large (~100k) output of some command executed on the remote system. If the output is not large then it doesn't happen. I tried with different encryption algorithm

I have a strange problem with sshd (from openssh-2.9p2) on Solaris 7. My shell is bash. When I open an ssh session , and type a Control-C to bash's prompt, the shell hangs. (But, if I for instance run "sleep 10" (during which time the pty is in cooked mode) and press Control-C, the sleep command is interrupted quite normally, and the bash prompt returns.)

Hello all, My scripts, which read stdout from ssh, weren't seeing EOF from the remote session.? It was being sent, but lost.? I tracked it down to the following code, in ssh.c, at ssh_session2_open: ??????? if (stdin_null_flag) { ??????????????? in = open(_PATH_DEVNULL, O_RDONLY); ??????? } else { ??????????????? in = dup(STDIN_FILENO); ??????? } ??????? out = dup(STDOUT_FILENO);

Hello, I just ran upon this problem and couldn't find it in bugzilla. SSH crashes (abort trap) if all of the following conditions are met: (a) option -f is used (crash happens when going to background), (b) reverse port forwarding is set up (option -R), (c) option ExitOnForwardFailure is enabled, (d) there are no actual port-forwarding failures. The problem can be reproduced by

Hello, I'm not sure if this has already been addressed, I looked through the archives and can't seem to find anything. I also did some Usenet searching and only found one article mentioning this, and it was in French. Anyway, the problem is that it appears as though when using privsep opensshd doesn't execute pam_session as root, and this causes pam_mkhomedir to fail.
