channel 17: chan_shutdown_read: shutdown() failed for fd21 [i1 o16]: Transport endpoint is not connected This is one typical error that I get running the following configuration: 1. CLIENT: openssh-2.3.0p1-4 as the client ssh 2. SERVER SSH Version 1.2.26 [i686-unknown-linux], protocol version 1.5. Standard version. Does not use RSAREF. Linux mark 2.2.17 #2 Fri Oct 20 02:26:15 PDT 2000 i686 unknown 3. SQUID: Squid Cache version 2.3.STABLE4 4. Connection forwarding (no compression) from local port 2080 to remote port 2080 where SQUID listens on. Here's a picture of the configuration: Browser --> ssh client port 2080 (as proxy for browser) --> [Internet] --> sshd on some remote host (forwards connections to localhost 2080) --> squid (listens on 2080) --> [grab the requested page] The problem is that some of the connections work, others die with the error above on the Squid side. Please note that the current configuration works fine when using a different ssh client than openssh shipped with RedHat 7.0. For example an ssh compiled by myself works fine. Also, a Windows client F-Secure SSH 1.1 works fine. It looks like openssh has a problem with connection forwarding. I am doing this in order to prevent HTTP request loggin by my ISP.
Please test with current Fedora Core distribution.
No response, please reopen if still happens with a current FC/RHEL release.
