Well, I found 3 in one week (well, two were actual bugs, the other
was a non-feature). And I've only been using FreeBSD for 2 weeks now!
So much for the stable code base that FreeBSD claims. I like Linux
much better.
BTW, the bugs and non-features are:
Inability to turn on or off BROADCAST or POINTOPOINT flag for
loopback device.
Packets are still transmitted even though the UP flag is not turned
on in an interface. "ifconfig -a" reports the interface as being
down, but packets are still transmitted. To test this, start up
a SLIP connection, then type "ifconfig sl[whatever] down" and see
if you can still use your connection. You shouldn't be able to.
non-feature: The "rwhod" doesn't check connections to make sure they
are still valid before sending packets out. All the interfaces
are registered on startup, and are never updated. (BTW, Linux has
the exact same problem with it's "rwhod" command). The program was
written this way, so I consider it a non-feature instead of a bug.
Actually, if someone has an answer for these problems, I would really
enjoy hearing them. FreeBSD has given my roommate nothing but problems
(although he claims he enjoys it). :)
Take care,
