Package: syslog-ng
Version: 1.9.9-1
Severity: normal
Hi,
Since I upgraded syslog-ng from 1.6.5-2.2 to 1.9.9-1, I have not
modified the "syslog-ng.conf" file, and now syslog-ing output is
printed from pppd to all logged-in users.
This output is (incorrectly) printed to all logged-in users:
May 2 19:59:17 l1 pppd[23973]: Script /etc/ppp/ip-down started (pid 6786)
May 2 19:59:17 l1 pppd[23973]: sent [LCP TermReq id=0x2 "User request"]
May 2 19:59:18 l1 pppd[23973]: Script /etc/ppp/ip-down finished (pid
6786), status = 0x0
This output is (correctly) printed to the xconsole:
May 2 19:59:17 l1 pppd[23973]: Terminating on signal 15
May 2 19:59:17 l1 pppd[23973]: Connect time 406.4 minutes.

Here is a in-line copy of my "syslog-ng.conf",
#
# Configuration file for syslog-ng under Debian
#
# Facilities: auth, authpriv, cron, daemon, kern, lpr, mail, mark,
# news, syslog, user, uucp and local0 through local7.
#
# Priorities: debug, info, notice, warning (warn), err (error),
# crit, alert, emerg (panic).
