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.
