openssh 2.3.0p1 closing connection before command output comes through?
i'm getting some very strange behavior with openssh 2.3.0p1 that i don't recall seeing with 2.2.0p1. here's some short output that will probably sum up what's going on better than i can explain it: admin2:~$ ssh downtown1 df Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda3 8457624 2881868 5139192 36% / /dev/sda1 15522 1662 13059 11% /boot /dev/sdb1 8605584 5633920 2527472 69% /content /dev/sdc1 8605584 3261568 4899824 40% /logs admin2:~$ ssh downtown1 df admin2:~$ ssh downtown1 df admin2:~$ ssh -t downtown1 df Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda3 8457624 2881904 5139156 36% / Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Filesystem 1k-blocks Used Available Use% Mounted on Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Filesystem 1k-blocks Used Available Use% Mounted on Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Connection to downtown1 closed. admin2:~$ ssh -t downtown1 df Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda3 8457624 2881908 5139152 36% / /dev/sda1 15522 1662 13059 11% /boot /dev/sdb1 8605584 5633920 2527472 69% /content /dev/sdc1 8605584 3261664 4899728 40% /logs Connection to downtown1 closed. there's plenty of memory free (512MB total, 220MB free) and cpu load is low (0.05 up to around 0.10). system is slackware 7.1.0. using openssl 0.9.5a. using openssh 2.3.0p1 on both ends of the connection with publickey authentication. using openssh 2.1.1 (openssl 0.9.5a) with password authentication to the same server, everything works normally. devon

Problems with 2.4.0 SSH Secure Shell (non-commercial)
Hello to all I have OpenSSH 2.2.0p1 (openssl 0.9.6, Slackware, glibc 2.1.3) and there are some problems connecting machines that use SSH-2.0-2.4.0 SSH Secure Shell (non-commercial). Here is the output: OpenSSH Machine> ssh problematic Disconnecting: Corrupted HMAC on input. Problematic> ssh OpenSSH warning: Authentication failed. Disconnected; MAC error (Message authentication check fails.). $ telnet problematic 22 Trying 123.45.67.89.. Connected to problematic. Escape character is '^]'. SSH-2.0-2.4.0 SSH Secure Shell (non-commercial) .... With OpenSSH 2.1.1 everything looks OK. Greetings
