similar to: Timing out a channel exec request

When processing ~& with SSHv2 OpenSSH sends \004 (EOT) and does not bother sending SSH2_MSG_CHANNEL_EOF. Why is that? Why is there no direct way to get SSH2_MSG_CHANNEL_EOF or SSH2_MSG_CHANNEL_CLOSE sent? Or is there and I'm just missing it?

Hi, protocolkeepalives sends ssh_msg_ignore, which the ssh2 server handles incorrectly (i.e. it produces some output to syslog, instead of ignoring the packet): Jul 9 11:58:07 ren sshd[16580]: error: Hm, dispatch protocol error: type 32 plen 4 This patch implements a highly advanced function to ignore these packets ;) Matthew -------------- next part -------------- An embedded and

In the end, I'm trying to ensure a minimum equivalent of 128-bits of security. Group14 is 2048-bits, which roughly translates to 112-bits. [1] To this end, I disabled the "diffie-hellman-group14-sha1" and

Rsync supports the capability of compressing data before sending. So does OpenSSH. It would be probably be a waste of resources and time to enable both compression capabilities at the same time, but it is not clear to me whether, in general, it makes better sense to enable rsync compression or SSH compression. My first thought would be that SSH compression might yield better results, on the

Hi. >From my understanding the MaxStartups option can be set to limit the number of concurrent sessions the OpenSSH server opens. My concern is how OpenSSH handles the case where this number is reached. >From the code it looks like it simply closes the socket: sshd.c:1440 if (drop_connection(startups) == 1) { debug("drop connection #%d", startups); close(newsock);

Thanks; I did not think of that. I have just run a few basic tests with both rsync and OpenSSH in their default settings, when it comes to compression. SSH compression seems to have a very slight edge. However, I surmise that, given the number of knobs available on both sides (OpenSSH, in particular) one can tinker with settings almost endlessly in either side, probably being able to end up with

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

I have coded a patch witch allows to forward environment variables from the client to the server. To specify forwarding in your ssh client add the option ForwardEnv varname # forward varname with value # as in environment of the # ssh client. If variable is # not defined in the environment # of the ssh client nothing will # be forwarded. ForwardEnv varname=value # forward

I am using the OpenSSH client (version 5.2p1) in a Linux box L to interact with an embedded SSH server S. When carrying out a recursive transfer from S to L by means of the scp command issued in L (S does not support sftp) the client occasionally prints out a "lost connection" error message at the very end of the transfer. After some debugging I found out that the error message (as
