[adam@stolid ~]$ /sbin/route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.1.13 0.0.0.0 UG 0 0 0 eth0
192.168.1.0 0.0.0.0 255.255.255.192 U 1 0 0 eth0
[adam@stolid ~]$
But what calculates that destination there? I know I specified
192.168.1.13 and 255.255.255.192 in the router's configuration screens,
and 192.168.1.13 in /etc/sysconfig/network, but I don't recall entering
192.168.1.0 anywhere. I gather that's computed by Linux or the router
or both.

Which, among many other cases, includes mine exactly:
255.255.255.192 4 nets N.N.N.0 N.N.N.1-62 N.N.N.63
which they also call "class 1/4 C".

I un-checked "enable LAN DHCP" on every router config screen, and every
piece of my LAN now has a static IP.
BTW I set up "stolid" to be its own DNS and 'named' is running, but the
router's "Advanced LAN Statistics" screen still shows Verizon DNSs for
both "Primary DNS" and "Secondary DNS". I assume they're irrelevant
because 'named' never asks the router for a DNS... right?

I didn't even know 'lp' could handle PDF files. I've only used it for
plain text files so far.

If I'd been paying more attention, the fact that it didn't have an RJ-11
jack, but did have a DB-9 serial port and a DB-25 printer port would
have registered. :-)
In other computer news, I'm /mostly/ done setting up "stolid" with
Mandriva 2011.0. I'll be opening the case again to attach a 486DX
anywhere with duct tape to give it an "Intel inside". At least I know
why the chip's substrate feels like a ceramic tile -- I spent about four
months helping make the conductive paste that went into those. Also
I've tried installing new 64-bit distros on eris, but without much
success. Fortunately that's not essential for anything.

The local SPCA even had some stickers they'd put on the cage card for
things like "only pet", "no dogs", "no children", and similar. One of
my favorite cats there had an attitude of "been there, done that" --
nothing surprised her, not even leading dogs through the room as was
occasionally necessary. I think there could have been a dogfight in
that room and she wouldn't have reacted unless she thought she was in
any danger. OTOH one of my least favorite cats there hated me and only
me. I must have reminded her of somebody.

Once they work out who's dominant, things should settle down.

Probably what it does there. I know there are things pacemaker
recipients have to avoid, and I believe strong magnetic fields are part
of them.

I /think/ once every two or three months, plus occasional checks at the
doctor's office.

When he mentioned it, he was 22 and a civilian again, so I assume he
wasn't going for a career in the USAF, whether or not he had been before.

Not to that extent. I'd call it bad judgement -- if he doesn't want
grapes, maybe an apple? This after my repeating I'm not hungry at all.

A valid license, plus they still have the Taurus that's been "her car"
since 2003, besides "Dad's car".

I've read that sometimes it's easier for the person if the doctor or the
DMV becomes the "bad guy", rather than a family member.
