Hmm. Ok. I tried removing the part using tee so now it's like this: if [ -x /usr/bin/mrtg ] && [ -r /etc/mrtg/rm_127_switch-mrtg.cfg ] ; then env LANG=C /usr/bin/mrtg /etc/mrtg/rm_127_switch-mrtg.cfg 2>&1 >> /var/log/mrtg/mrtg.log ; fi
....and I am still getting emails to root. Shouldn't this be sending all the output to the file and not standard error? Here is the whole error message I am getting from MRTG. MRTG seems to be working like a champ BTW. I would just like to stop these error messages Thanks David Cron <root@backuppc> if [ -x /usr/bin/mrtg ] && [ -r /etc/mrtg/elem_switch-mrtg.cfg ] ; then env LANG=C /usr/bin/mrtg /etc/mrtg/elem_switch-mrtg.cfg 2>&1 >> /var/log/mrtg/mrtg.log ; fi Content-Type: text/plain; charset=UTF-8 X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/root> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=root> Subroutine SNMP_Session::pack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 149 Subroutine SNMP_Session::unpack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 149 Subroutine SNMP_Session::sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 149 Subroutine SNMPv1_Session::pack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 608 Subroutine SNMPv1_Session::unpack_sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 608 Subroutine SNMPv1_Session::sockaddr_in6 redefined at /usr/share/perl/5.14/Exporter.pm line 67. at /usr/share/perl5/SNMP_Session.pm line 608 On Tue, Apr 1, 2014 at 7:05 AM, David Nelson <david.nelso...@gmail.com>wrote: > MKS, > > Thank you !
