An application (shtml.exe from frontpage 4.0.4.3) logs syslog messages properly under RH 6.0 but not under 6.1 or 6.2. All 3 systems report: sysklogd-1.3.31-x libc-5.3.12-31 The 6.1 system also has: compat-glibc-5.2-2.0.7.1 There also seems to be other compatibility issues with this app. But we remain clueless without logging.
It's using the wrong socket type in libc5. Go to: http://www.redhat.com/support/errata/rh42-errata-general.html#syslogd, grab the libc5 binaries there, and put them in /usr/i486-linux-libc5/lib (or whatever the directory is called; it's something close to that.)
1) Links at http://www.redhat.com/support/errata/rh42-errata- general.html#syslogd are old 2) Forcing an install of libc-5.3.12-18.5.i386.rpm has no effect (these install in /lib not /usr/i486-linux-libc5/lib; havent tried building from sources yet) 3) Installing sysklogd-1.3.31-0.5.i386.rpm gets us logging again (guess we will live under the shadow of syslog DOS attacks)
