Date: Thu, 04 Feb 1999 04:18:10 GMT
Yes, I did have that problem before, but I'm past that now. I can get it to work
when I set up the adapter to use DHCP, and then everything is fine, but when
I switch over to a "manual" configuration for the adapter, thats when I cant
get it to work. I havent seen the "delaying eth0 initialization" message
in a long time, so I dont think thats the problem anymore...
Thanks though.

Subject: PPP questions
Date: Wed, 03 Feb 1999 23:12:15 -0500
Greetings,
I've recently entered the world of linux, and am banging my head on a
number of seemingly simple problems. Perhaps someone could help me ...
How do I check the connect speed of my modem when I fire up PPP? I have
a feeling I'm not getting 56k(or 53.3, whatever) out of my 56k modem.
I imagine its somewhere in the /proc dir, but where?
How do I enable ICMP through IP masquerading? I can do everything I
need EXCEPT ping. I recall reading about an ICMP Masq patch out there
somewhere, but can't find it anywhere.
Also, whats a good web caching engine to be running? I've heard good
things about squid and harvest. Any recommendations?
Thanks,
Iven Connary

I think I found something that works.
fetchmail -n
or norewrite
It is suggested in the man pages for fetchmail not to use norewrite.
Anyone know what problems it will cause if any?

This machine is being used for e-mail by about 10 people and for syslogs

If I kill syslogd _or_ remove the syslog forwarding from the _other_ two

In your /etc/inetd.conf, uncomment the telnet line. If that doesn't
work, make sure there is a line for Telnet in your /etc/services file.
The default is TCP port 23.

You need to export /usr and /home on the server (i.e. put them in
/etc/exports file). See "man export" for more info. Then, on the client, you
put them in /etc/fstab as host:/direcory and nfs as the file system.
/usr/local should not be mounted locally. Since you're gonna mount
everything from the server, install only the bare minimum on the client.
That's about all.

Okay, I have a little 486/8MB here that I want to turn into a Linux
workstation. How should I partition/install so that I can mount my '/usr',
'/home' directories from my Linux server? Will that include X-Windows?
What should I mount locally, and what should I share over the network?
Should I mount '/usr/local' locally?
Give me the scoop! Thanks!

Look in the directory /etc/rc.d and you should find the startup/shutdown
scripts. These tend to vary by distribution, so you may have to do some
hunting. Try and find the script that sets up the ethernet card and add
the route command there.

I can now connect and hold the connection but still can't totally get out.
Here is the report from /var/log/message after a successful connect
.....
.....
send(^M^M)
send(ppp^M)
Serial connection established
Using interface ppp0
Connect ppp0 <--> dev/modem
Unsupported protocol (0x802b) received
not replacing existing default route to eth0
local IP address 128.143.3.116
remote IP address 128.143.3.100
I can successfully ping 128.143.3.100
but can't ping 128.143.3.116 (which I thought should be my machine)
nor can I ping anything else
The UVa network runs mainly on IPX/SPX although under NT I connect with only
TCP/IP running and it works fine
The problem seems to me to be
Unsupported protocol (0x802b) received
not replacing existing default route to eth0
But I'm just not familiar enough with Linux yet to really get a sense for
what this is telling me

If you're not concerned about stability and security, use windoze. (I'm
assuming price is not an issue here either...). If you want this thing to
actually work, use Linux.

Date: Thu, 04 Feb 1999 00:03:47 -0500
I assume you have a link light on the back and it's good.
1. Use RFC 1918 addresses (192.168.1.1 - 192.168.1.3 for your
situation). Use a mask of 255.255.255.0.
2. Is NT really running DNS, or is it running WINS? Linux doesn't talk
WINS (unless you're running SAMBA and let's not go there yet). Try
pinging the address, not the name.
3. Not sure on your network topology, but if it's 10Base-T, use a cross
cable between your NT and 98 machines (verifies the cable is good).
Then try it between your NT and Linux. This will eliminate your hub as
a problem. Then use the cable from the 98 machine to connect the Linux
box to the hub (you know it's good already).
4. Verify all your interupts for the RH machine. Is your ethernet
adapter conflicting with something else? I just spent 3 hours dealing
with that last week myself, and I think things acted pretty similar.
5. Make sure that you either have support for the NIC compiled into the
kernel or as a module. What is it anyway?
Hope that gets you going.

Date: Thu, 04 Feb 1999 05:02:57 GMT
Newbie Linux guy here,
Trying to set up a peer to peer network between red hat 5.2 and win98. Have
10/100 cards in both, connected to 5 port 10Mb hub.
Both cards (and hub) indicate live link. TCP/IP set up properly on win98
box. When I try to ping my Linux box I can see activity on the hub, but no
answer from Linux box. When I try to ping PC from Linux, no activity on
hub/activity and collision light lights up.
I am trying to set up Linux box as a client to my win98 machine, where I
have a web proxy running (I know...should be other way, but will be getting
cable modem soon, so both will be directly connected...). I want to run
samba on Linux for file/print services.
Could someone please post or point me in the direction of a step-by-step how
to set up this type of network?
Thanks for any and all help.
Please remove the tryme's from address to reply to me.
