similar to: Send Break to terminal server

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,

I'm reading this fine article on O'Reilly: http://linux.oreillynet.com/lpt/a//linux/2001/11/08/ssh_keystroke.html <quote> The paper concludes that the keystroke timing data observable from today's SSH implementations reveals a dangerously significant amount of information about user terminal sessions--enough to locate typed passwords in the session data stream and reduce the

I am trying to initiate an sftp session from a Linux (Redhat) to a LynxOs machine (where i have ported opnessh-2.9p1) and configured without PAM support (as I was not able to find PAM version for LynxOS operating system) I get the following error: $ sftp -P /home/telica -l telica -v ben select: Bad file descriptor read: Input/output error sftp> Can somebody help me asap on this?

Hi, We recently upgraded OpenSSH from 7.5p1 to 8.0p1, and received a report that there was a behavioral differences where the ssh session did not disconnect after a remote background command execution. For example, "ssh user at example.com 'tail -f /var/xxx &' After looking at the debug logs and comparing the code, it seems there was a bug in the portable version during the

Greetings, I have a problem with OpenSSH -current and SCO 3.2v4.2, when I execute a remote command or exit from a session, the connection hangs, ( line 326 of serverloop.c).

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

Initially send this mail to user group. then realized this is more apt place. Apologies for posting in both groups... Hi all, We're using openssh version 4.7p on our linux 2.6-22 kernel. We have a Java based GUI that opens a secure shell connection to this linux box. To do something over the connection, the GUI opens a session (some times 3-4 simultaneous sessions) & once done, it will

Hi, I'm a little stuck on getting reverse connection working reliably from embedded devices running dropbear 0.51 to Ubuntu 8.x openssh. Connecting to local reverse socket often fails (not always) with "ssh_exchange_identification: Connection closed by remote host" My devices can reverse ssh and open a port on my server always, but often when the server is creating the reverse

Hello, In response to the timing analysis attacks presented by Dawn Song et. al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html we at Silicon Defense developed a patch for openssh to avoid such measures. Timing Analysis Evasion changes were developed by C. Jason Coit and Roel Jonkman of Silicon Defense. These changes cause SSH to send packets unless request not to,
