Hi Gabriel,
Something is fishy (firewalled, IP-translated?) with the DNS setup of
that machine, since this is what I get on s10:
[Mon Dec 15 19:28:26 2003] [error] access to
/raw/msu/mmp/lbs271.sequence failed for 141.209.165.43, reason: Spoof
request from
Looks like the reverse DNS lookup does fail.
# traceroute lon-capa.phy.cmich.edu

Somewhere around fo027-r1.snmp.cmich.edu, the hostnames get dropped.
Does not happen with other boxes, see for example

- I am not network-savvy enough to understand what's going on, but
something is different - maybe your network coordinator on campus can
look into this? Anybody else any ideas?
