Description Thomas J Pinkl 2002-10-30 14:43:38 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020513

Description of problem:
I'm using a "chat -v -s -S" command to capture chat's output to my own
log file (ie. not syslog).  Sometimes the log will be incomplete.  It
may be missing parts from the middle of the conversation or the entire
log may be empty.

When I looked at the 'chat' source I saw that it mixes I/O modes.  It 
uses both "write(2,...)" and "fprintf(stderr,...)".  I believe this is
the cause of the logging problems.

I patched my source to 'chat' such that it doesn't mix I/O methods.
Since then, the logs have been complete.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. run logs of pppd sessions

Additional info:

I submitted a patch to the "linux-ppp" list on Apr 19, 2002.  The 
subject line was "chat timestamp patch".
Comment 1 Thomas Woerner 2004-08-16 12:13:02 EDT
Please verify this with a newer version of Red Hat Enterprise Linux or
Fedora Core and reopen it against the new version if it still occurs.

Closing as "not a bug" for now.
