Subject: how to change startup config?
Date: Sun, 25 Jul 1999 07:00:36 GMT
in the process of trying to connect ppp, i re-installed and loaded
everything . now when i look at my chat scripts to follow the HowTo
methods i find lots of things running, i think they are servers, like
"http" and others.
is thre some equivalent of the dare i say windoze "startup folder" by
which i could reduce the things that load a t startup?
or is this what is meant by <shudder> "recompiling the kernel"
</shudder>
i would ask to excuse my ignorance but i notice i am not alone in my
initial encounters with what i expect to be the beginning of a long
friendship.
thanks for assistance

Subject: Majordomo difficulties
Date: Sun, 25 Jul 1999 07:37:43 GMT
I've installed majordomo and seem to have everything configured correctly.
Ran the configuration scripts, and everything came out normal. Edited the
majordomo.cf file. The weird thing that is happening is that when I send a
command to majordomo via email like 'lists' it will only respond to the
local machines users. I can email majordomo locally from my user account on
the machine with 'lists' and it responds within a matter of seconds. I went
home and tried to email majordomo on the server with the same command and I
never got a reponse from majordomo. I sent various other commands like help
or info to see If I would get anything back, but same thing.
I did check the majordomo.cf file and was curious if this had anything to do
with it.
# $sendmail_command = "/usr/lib/sendmail";
$sendmail_command = "/usr/sbin/sendmail";
I currently use SuSE Linux 6.1 and have sendmail in both sbin and lib.
Anyone have any suggestions as to why majordomo only reponds to local users?
TIA

Subject: telnet timeout: win9x -> linux -> remote host
Date: Sun, 25 Jul 1999 00:55:26 -0700
Hello, I've got a small, rather odd question. I've a RedHat 5.2 system
hooked up to my DSL, routing all network traffic to the rest of my lan
(Win 98 & 95 mostly). It all works just fine. However, while telnetted
into a remote server from a Win9x box (whether having first telnetted
into my linux box, then out to the remote server, or directly to the
remote server) and I let the session sit (which I am VERY used to doing)
I get timeouts. I know for a fact that it's not the remote server (cuz
from other locations I'm able to let the session sit untouched for
hours). I've been going through the config files and havn't been able to
figure out if there's some keep-alive that's not turned on (or a timeout
setting) somewhere in my Linux box. I'm able to telnet into my Linux box
and it doesn't timeout ever. ??? Kinda lost on where/what to look for on
this one. (please excuse if it's a simple solution, not a *nix
power-user, and have been looking for this problem for many an hour...
brain... loosing... power.... ugh).
Thanks in advance for any help.

Date: Sun, 25 Jul 1999 03:47:22 -0400
Hello everybody,
I'd like to know if anybody has used Condor to checkpoint an MPI
application on linux 2.0.32. I'm trying to use the standalone
checkpointing feature offered by Condor but I'm unable to use
condor_compile to compile an MPI application. In other words I'm not able
to use condor_compile with mpicc. I've read most of the manual but I have
not come across any information regarding this feature. If anybody has
used Condor with MPI please let me know your experiences. Otherwise, if
anybody has any ideas or pointers on how to checkpoint an MPI application
I'm all ears.
Pratap

This may sound stupid but I need to say this. You can't telnet or rlogin to the
root account of a linux machine.

Hi,
If you want to use your NIS server automount maps, turn your linux
host into a NIS client. Basicly you should run ypbind. On Slackware
you need to uncomment NIS related stuff in /etc/rc.d/rc.inet2 and
create /etc/defaultdomain file to contain your NIS domain name.

I have too many comps...
I just got a pentium 100 and a 486 (40 bucks for both 8-)) both with 16
megs of
RAM and about 800 MB HDD. That is in addition to a AMD 233 and a
imac ( my wifes)
Now I want to play around with a network ( I have 3 cards and a hub)
I just connected the P100 and the AMD 233 and I can ping them etc.
I want to add the 486 and the mac. I do not know what would be the
best configuration (probably the 486 as a router)
The main pourpose of the network would be share files-printers
and also test some PERL. OK Ok Maybe some games
Any suggestions would be greatly appreciated!

Check the errata. (netkit_base and traceroute)
http://www.redhat.com/corp/support/errata/rh60-errata-general.html
There's an error in ping - "ping fails at odd bytes" - bug #3284:
"On all platforms, ICMP checksums were incorrectly computed for packets
containing an odd number of bytes. In addition, "ping -f localhost" does
not drop packets."

Netscape 4.51 running under Linux 2.0.36 kernel and X 3.3

For me, all this does is play a (loud) version of "Happy Birthday to You"
and show some badly animated lo-res large-type font messages.

You should configure your ipx interface first. Try
ipx_interface add eth0 -p EtherII
before mounting. Using
ipx_cofigure --auto_interface=on --auto_primary=on
does not always work if you have Windoze computers
on your network. Refer to IPX HOWTO if you still
have problems.

Hi,
In order to be able to run programs from mounted directories, add exec
option
to your /etc/exports on Slack, like this:
/mnt/red your.redhat.machine(rw,no_root_squash,exec).
To mount something from RedHat machine, check that yo have rpc.mountd
and rpc.nfsd running. On Slack they run by default, I'm not sure about RH.

Windows does not automatically refresh the network neighbourhood, you need

Why don't you configure all the pc's the use the same master browser or set

This is from a post i wrote a couple of days ago...BTW this does work.
=====
I just set this up tonite....*seems* to work. here is what I did...(I'm using
RedHat6)
in the /etc/rc.d/rc.firewall script
/sbin/ipchains -I forward -p tcp -s <external ip/subnetmask> <external port> -j
MASQ
/usr/sbin/ipmasqadm portfw -a -P tcp -L <external ip> <external port> -R
<internal ip> <internal port>
Example:
My ip to the outside world is 201.201.201.201 with a 24 bit subnet (class
C)...my internal subnet is on the 10.0.0.* range with a class C as well. I want
to forward all port 2000 traffic to my internal masqed ftp server at 10.0.0.50.
/sbin/ipchains -I forward -p tcp -s 201.201.201.201/24 2000 -j MASQ
/usr/sbin/ipmasqadm portfw -a -P tcp -L 201.201.201.201 2000 -R 10.0.0.50 21
ok this seems to work BUT, it will *NOT* work from the router *OR* any of the
masqed machines.. you /must/ test this from the "outside world".
