Red Hat Bugzilla – Bug 98756
SSH Connections Hang/Timeout on large amounts of text output under redhat linux 8.0
Last modified: 2007-04-18 12:55:32 EDT
On a minimized redhat 8.0 install commands like strace, or untarring a large
file will cause the session to slow to a crawl and freeze. I suspect that this
is actually any command with large amounts of output but cannot confirm.
Furthermore, we have several redhat linux boxes with other package sets
including this that do not exhibit this behaviour. Therefore, I suspect that the
package may be the cause... but exactly which I do not know.
(I've tried switching from en_US.utf-8 to en_US to no avail)
We are using Putty .53b as a client; however, I can not confirm this to be a bug
with their software.
strace ssh image@<host> cat somefile
the strace will begin and you can watch the output slow to a crawl, and finally
stop after an unknown period of time (in a couple cases).
See attached package list.

list of packages for our particular install
The Bug is in PuTTY, not OpenSSH.
rpm -qail done from within a putty terminal direct induces the lockup.
rpm -qail done through a known good server connecting the the problem server w/
openssh client works flawlessly.
rpm -qial from console of known good server to problem server works flawlessly.
Will follow up with the putty team.
