Anyone know what what could be the problem with dhclient? Some buffer is
full but what?
Nic is 3Com 3c905B-TX, FreeBSD 5.4-STABLE & PF.
Typically, that sort of message indicates that the firewall rules are
preventing traffic from going out, or packets are getting stuck in a queue
until it fills up, or maybe even a bug somewhere in the particular combination
of kernel firewall options enabled, high optimization or CPUTYPE settings, and
your particular hardware, depending on how lucky you are. :-)
Does the problem go away if you use a trivial "permit all" PF ruleset?
Does the problem go away if you use a trivial IPFW "permit all" instead of PF?
Does the problem go away if you use a stock 5.4 release kernel?
The 3Com 3c905B-TX is an OK NIC, apparently the later C revision or the
918/920's are pretty decent, but anyway--
...does the problem go away if you switch to another (known good) NIC?
