Hi all, This problem is a symptom of a library issue.
The 'ping' utility has the a similar problem. Until upgrading from 'Etch' to 'Lenny' on AMD64 (dual Opteron) we had no problems with either. The system runs 'Smokeping' tp monitor our networks. Now it is basically useless. The results from gettimoefday() are incorrect. The values have a granularity of 4 milliseconds on our system, which I guess relates to the 250Hz timer tick. Unfortunately ping uses the gettimeofday() function to measure RTT in microseconds, and obviously this isn't going to work with a4ms granularity in the returned value. I can confirm that the problem is not in 'ping' itself, the same binary which works fine on an Athlon system fails in the same way on the Opteron. A simple 'C' program to print time increments by using the gettimeofday() function shows the same problems as ping. tornado:~$ >>> ping lightning PING lightning.local.jubileegroup.co.uk (192.168.44.236) 56(84) bytes of data. 64 bytes from lightning.local (192.168.44.236): icmp_seq=1 ttl=64 time=4.00 ms 64 bytes from lightning.local (192.168.44.236): icmp_seq=2 ttl=64 time=0.000 ms 64 bytes from lightning.local (192.168.44.236): icmp_seq=3 ttl=64 time=0.000 ms 64 bytes from lightning.local (192.168.44.236): icmp_seq=4 ttl=64 time=0.000 ms ^C --- lightning.local.jubileegroup.co.uk ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3007ms rtt min/avg/max/mdev = 0.000/1.000/4.000/1.732 ms tornado:~$ >>> ssh lightning Enter passphrase for key '/home/ged/.ssh/id_dsa': g...@lightning's password: Linux lightning 2.6.26-1-686 #1 SMP Sat Jan 10 18:29:31 UTC 2009 i686 The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.
