Hello,

We're having a T1 outage at the moment, but I noticed that when we have a 
loss of internet connectivity that it affects ping with regard to non-local 
addresses.  Given the message, it looks like a bad side-effect of using NIS.

(substitute 11.22.33.44 with any pingable address outside your local subnet)

sysmon1% ping 11.22.33.44
PING 11.22.33.44 (11.22.33.44): 56 data bytes
yp_match: clnt_call: RPC: Timed out
yp_match: clnt_call: RPC: Timed out
yp_match: clnt_call: RPC: Timed out
yp_match: clnt_call: RPC: Timed out
yp_match: clnt_call: RPC: Timed out
yp_match: clnt_call: RPC: Timed out
yp_match: clnt_call: RPC: Timed out
.... ad infinitum

and ping sticks around in the process table and continues to error out until 
you kill it, or until your route/connectivity comes back.   Traceroute 
exhibits the same behavior.

strace reveals:

execve("/sbin/ping", ["ping", "11.22.33.44"], [/* 35 vars */]PIOCWSTOP: 
Resource temporarily unavailable
execve("/usr/sbin/traceroute", ["traceroute", "11.22.33.44"], [/* 35 vars 
*/]traceroute to 11.22.33.44 (11.22.33.44)PIOCWSTOP: Operation not permitted

Pinging addresses on the local subnet, however, works fine.   This is kind of 
annoying... is this a configuration problem of my own or is this a bug?

Happily running FBSD 4.5.

Thanks,
