I have a script I put in /etc/cron.fiveminutes graphs.sh #!/bin/sh env LANG=C mrtg /home/admin/domains/my---server.com/public_html/traffic/load/mrtg.cfg --logging /dev/null >/dev/null 2>&1 env LANG=C mrtg /home/admin/domains/my---server.com/public_html/traffic/eth0/mrtg.cfg --logging /dev/null >/dev/null 2>&1 #exit 0; Problem is there is some bug that raises an error even though mrtg still graphs fine. [root at server cron.fiveminutes]# env LANG=C mrtg /home/admin/domains/my---server.com/public_html/traffic/eth0/mrtg.cfg --logging /dev/null Subroutine SNMPv1_Session::AF_INET6 redefined at /usr/lib/perl5/5.8.8/Exporter.pm line 65. at /usr/bin/../lib64/mrtg2/SNMP_Session.pm line 594 Subroutine main::AF_INET6 redefined at /usr/lib/perl5/5.8.8/Exporter.pm line 65. at /usr/bin/mrtg line 97 /usr/bin/rateup: /usr/local/lib/libpng12.so.0: no version information available (required by /usr/lib64/libgd.so.2) The issue is it tries to alert root every time this script is run. I thought adding the ">/dev/null 2>&1" would stop that but it does not. Is there anyway to get the script to ignore the error and not alert root? Another solution is to install a newer version of mrtg from source which supposedly resolves the issue but I would rather just ignore the error for now until a newer 64bit rpm comes out since its not hurting anything except the annoying warning messages.
