I'd sniff the network traffic with tcpdump to a file for a while, and then run Wireshark on the file. Something like tcpdump -i eth0 -s 0 -Uw - 'tcp port 80' > /home/debbie/tcpdump.out.`date +"%Y%m%d%H%M%S"` & I'd run tcpdump on both the master and a slave. I'd hope that you have your system clocks all in sync to within a fraction of a second using ntpd so that you can compare the logs. :) > ... here's the packages that they upgraded in case anyone knows of > anything in one of those: ... My guess is that something else has been changed too. -- 73, Ged. _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
