What you need is ppp support in the kernel and a program to answer the phone
like mgetty.

Sorry, while what you describe (latch up, etc.) can happen, but it's still
bullshit because it has nothing to do with ordinary hard drives crashing
at a high altitude.
There's a good reason why Seagate (and all other manufacturers
specify operating altitudes. And since older (lower density drives)
have heads that in general fly at a somewhat higher altitude over
the disk surfaces, that explains why older drives can tolerate the
higher altitude better than newer drives.

You may want to check whether your mpeg player supports buffering.
Typically, the problem is not that your overall system performance is
too bad, but that peak performance does not suffice.
E.g.: For mpg123 (which I use), you can give the switch `-b 2048' to
allocate a two-megabyte audio buffer. You will have to read the
manual for your mpeg player to see how it is done there.
If that is not enough, i.e. your system is actually too slow, the next
step would be to switch to a more efficient mp3 player. mpg123 is
very fast but does not have a graphical user interface.
If all else fails, you could always play the mp3 files as mono or have
the program do some downsampling. Of course, these alternatives will
reduce output quality.

from the pppd-2.3.11 man page:
usepeerdns
Ask the peer for up to 2 DNS server addresses. The
addresses supplied by the peer (if any) are passed
to the /etc/ppp/ip-up script in the environment
variables DNS1 and DNS2. In addition, pppd will
create an /etc/ppp/resolv.conf file containing one
or two nameserver lines with the address(es) sup-
plied by the peer.
It has been around since about 2.3.7, although I don't know when it
made the man page. I can confirm that it does work !
The only thing to note is that resolv.conf is read when a process
using the resolver starts, so I think that any process already running
will not get the new DNS addresses.

You can't mount a Tape. You can mount a disk.
To do a backup: Arkeia Backup is a fine Software to do that.
kdat, taper and PerfectBackup etc. will work too.
Or at once with commandline tools:
(be sure: SCSI support aktivated, Tape _Module_ loaded (st_mod),
or hardcoded in Kernel)
i.e.:
root@planet # cd /
root@planet # tar cvzf /dev/st0 *
or:
find / | cpio -ovF /dev/st0
This represents the tape:
crw-rw-rw- 1 root disk 9, 0 Aug 7 1999 /dev/st0
to understand the commands read this mans:
man cpio
man tar
man find
man mt

Subject: Samba / Winblows thru a serial connection Can it work?
Date: Fri, 14 Apr 2000 10:36:39 GMT
Morning Folks.
This is really a general question. I have a PC running a
SOHO board and AMD k6-2 400 with all the standard hardware. I also
have a laptop. I have Slaksware Linux running on both machines no
problems. I have winblows running on both nachines no problems.
I can do a serial connection thru a comm program from Winblows
to Linux no problem. I can do Linux to Linux no problem. I've been
reading how to's for two weeks and just can't seem to find the answer
to this one.
My question is this, Is it possible, if so how? To get
Winblows to connect to Linux ( Samba ) thru a serial connection rather
than an actual network card?
Please reply to my e-mail as my provider does not get the full
newsgroups headers and I probably won't get your reply if you just
post it.

Unlike all the cool stuff you've written.
This guy has had to reverse engineer the PPA protocol
without any cooperation from HP. The black-and-white
version (pbm2ppa) works pretty well without any difficulty
in setting up. I haven't tried the color version (pnm2ppa).
Getting a new printer would indeed make things easier. HP
deserves a hearty kick in the ass for this. But Tim Norman should
be thanked and congratulated for his work in the face
of their non-cooperative attitude.
