Hi All, I am trying to decode the message received from openssh client 3.1.0 Following is the third message which I received. length = 0000 008c padding length = 06 messagetype = 1e (SSH2_MSG_KEX_DH_GEX_REQUEST_OLD) padding = b8 218e c680 and the next four byte should have the n which is 0000 0080 which is less than 1024. 0000 008c 061e 0000 0080 2a19 a9e4 05fb aee2 b107 4fa9 f0c1 83d3 3bf0 15a2 8dc8 a74b 7be1 6cab 817f cffc b835 04f2 0958 850c b2ec dc0a 81de 0929 2d4c 9a6c 17a8 5a81 95bc 657b 0ac0 6a8e 246...

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?

...tually find out that a message it has sent was unrecognised rather than simply hanging, and perhaps even have a fallback. This would appear to be a MUST in RFC 4253 section 11.4, if I'm reading it correctly. (Discovered while debugging a twisted.conch hang that turned out to be due to sending SSH2_MSG_KEX_DH_GEX_REQUEST_OLD, but it would have been easier to spot if I'd got an unimplemented packet back from sshd.) -- You are receiving this mail because: You are watching the assignee of the bug.

I just upgraded to OpenSSH3.2.3p1 as it seemed that UsePrivilegeSeparation yes might help with my problem (connections forwarded are owned by root instead of the user I logged in as on the server), but instead, sshd barfs on receiving a connection.
