First ff, I'd like to apologize if this message hits the list a
second time, but I didn't receive the first one, so I'm resending it.
Sorry, too, for the length, but I figured more info would be better
than less. Here's the original message:
I have two FBSD boxes connected via an ethenet hub that were
talking just fine, last week (when I last rlogin'd from this machine
to that one). Last night, while online (via modem/ISP), I tried to
rlogin again from this box (FBSD v4.4) to that one (v3.2), this box
froze -- locked up so tight I had to do a hard reset.
When it rebooted, I ping'd myself (using both "localhost" and the
hostname) successfully. I then tried to:
- ping the other machine
- rlogin to this machine from the other one
- ping this machine from the other one
All of those actions caused this machine to lock up -- immediatedly
and requiring a hard reset. Ctrl-Alt-Delete would not work,
Ctrl-Alt-Backspace would not dump the window manager, Ctrl-Alt-Fn
would not bring up any of the vt's, the mouse pointer would not move,
and no key combination I could think of had any visible effect,
whatsoever.
Since, when I ping'd this machine, I could see the hub light flash
with each packet send (and the light for this machine was glowing
steadily, per normal operation), I suspected the physical networking
might be okay, but I booted it to Win98 just to confirm. With w98
running, this machine talks with that one, just fine.
So, something seems to be wrong with my FBSD configuration or
software. I have not purposely done anything to change my networking
configuration since it last worked. I have installed some new ports
via ftp, which leads me to wonder if one of those might have
misbehaved and put me in a pickle.
At this very moment, I am using FBSD while connected to the Net.
I can ftp to other machines on the Net, but any attempt to talk to my
other, local, machine would surely make this machine lock up.
My hosts, hosts.allow, and inetd.conf files are unchanged since
Jan.31 and I had a working network more recently than that.
I am not using this as a gateway to the net for the other machine.
The other machine is currently booted to FBSD and I'm logged into
it, too -- yet I don't see it in a netstat -r listing on this
machine. (Shouldn't I?) Below, I'll paste a list of my distfiles
(some of which were brought in by dependencies), what netstat -r
showed before I used ppp to connect to the Net, my ifconfig -a
output, my dmesg output (which shows the evidence, at the end, of my
having done a hard reset)
Any help would be very much appreciated.
Thanks,
Bob
