Hi, we are using OpenSSH_2.3.0p1. When using non-interactive mode, sometimes lines are swallowed from standard output: root at hydra:~ # ssh anderson "ls -l /usr/sbin/sshd" -rwxr-xr-x 1 root root 612344 Nov 25 20:26 /usr/sbin/sshd root at hydra:~ # ssh anderson "ls -l /usr/sbin/sshd" root at hydra:~ # ssh anderson "ls -l /usr/sbin/sshd" -rwxr-xr-x 1 root root 612344 Nov 25 20:26 /usr/sbin/sshd At the same time the following appears in /var/log/messages: sshd[6741]: error: channel 0: internal error: we do not read, but chan_read_failed for istate 8 We tested several kernel versions: 2.2.16, 2.2.17, 2.2.17-SMP with some local patches, and 2.2.17, 2.2.18pre24, 2.2.18pre24-SMP unpatched. Compilers used to generate the kernels were: gcc-2.7.2.3, egcs-1.1.2 and gcc-2.95.2. The problem could not be reproduced on SMP machines and only occurs in non-interactive mode. The problem did not occur with OpenSSH-2.1.1p4 The problem also disappears if ';true' is appended to the command line executed remotely. Best regards, Stefan
I have the same problem with openssh-2.3.0p1 on sun solaris 2.6 sparc. ssh -l root gaia echo \$PATH would sometime produce nothing to the standard output.
