Keywords: SunOS Message-ID: <3821@kalliope.rice.edu> Date: 9 Jun 89 13:52:38 GMT Sender: usenet@rice.edu Organization: Sun-Spots Lines: 28 Approved: Sun-Spots@rice.edu X-Sun-Spots-Digest: Volume 8, Issue 29, message 2 of 17 I reported a telnet problem which occured intermittantly. Symptoms: no echo on login or during session, j needed as . Several people responded; thanks to all. Dick St. Peters (did I get that right?) suggested that this was a well known problem, in which a job left running holds on to it's parents' pty after logout. This renders the pty useless as above. Since we have recently experienced an increase in users and server/daemon processes, we had not seen this before (I suspect it went unreported for a while.) I tested this out by killing off processes attached to ptys (but not ttys!) after the problem showed. This freed up the pty. Also, a person logged in under the weird conditions above showed the same pty as an already existing process! So I believe that this is the problem. I am going to call Sun for the patch. Guy@auspex.com sent along a useful program to cure pty's of "half-remote" mode. I tested this, but it did not fix the problem. Still, it eliminated what had been the prime suspect in my mind. Thanks, Guy! Mike@wuee1.wustl.edu: Couldn't reach you via mail...if you want further details, write and include a numerical path. Look for ptys which are running something but have no current login attached (or are different from the current login owner). Hope this helps.
