Hi
I just installed RedHat 5.2 Server and I when I started X windows ( startx )
I could not see the utility to add users.
I thought I remembered from 5.0 that there was a utility to add users

Well, inefficient, yes, in a way. You don't need a class B network for
2 machines . However, this is a perfectly valid IP address for private
networks. See RFC 1597 .

The route _itself_ is correct. What's missing is the route to the
network, though. The above listed route is a route to the host at
172.16.1.2 , not a route to the 172.16.1.0 network . The command
should be
route add -net 172.16.1.0 eth0
otherwise only the 172.16.1.2 address is reachable via the eth0
interface (and not 172.16.1.1 or all others).
>and my mask for the lo

[...]
Wrong (though irrelevant) . 127.0.0.0 must have a 255.0.0.0 netmask.

How does your /etc/route.conf look like?
Do a

before you get connected and
# route -n
after you get connected.
How do you start masquerading & firewall (ipfwadm ...) ?

all right, here we go...
first, head on over to www.socks.nec.com and git yerself a copy of socks5
(never mind that you are using a socks4 proxy fer now)
the webpage is pretty informative and the documentation is good, so you
should be able to set your box up to be a client for your socks4 server
fairly quickly(upgrade the server to S5 iF you can itll make your life a
lot easier)
once you have the client working, getting a program to work over the
firewall is as simple as running a script. it'll be something like
bash# runsocks {program}
and the program will work like a charm with your wall
of course some programs let you compile them for use with the socks
libraries and this is a lot cleaner
if you have any more questions, feel free to email me i'll be glad to help

Subject: intranet confusion
Date: Sat, 27 Mar 1999 08:52:29 GMT
I have a pentium computer that has MS personal web server and cold
fusion server running on it. It works fine as a stand alone piece of
equipment. I also have a number of 486 computers running win 3.1 that I
would like to attach to the pentium to make a little intranet with ftp
capabilities. I am really very confused as to what I need. I am
thinking that I need a proxy server and a ftp server, which I would like
to be Linux. I'm not quite sure what this means. I have installed
slackware 3.6 on a 486 computer before, but that's all I know how to
do. I have so many terms floating in my head right now. Do I need to
install a DNS server? DHCP server? HTTP server? WWW server (I'm assuming
not since that is what MS PWS is)? Socks Server? I'm sure that I have
looked through about 100 messages on Dejanews but they are not giving me
any answers. I have a 2000 page Linux book that is not giving me
answers.

My question would be, Do you have ppp setup? Read the man pages on ppp or
pppd. It will give you all sorts of info. Also go to /etc/mgetty+fax or
/etc/ppp and at the prompt, do a:
grep "ppp" *
to find files with Auto_ppp or ppp, which RH 5.2 should have already in one
of those files. Then read the file and it will give you a little more info
on what you are looking for.

I have been running UNIX boxes for almost ten years, and I have never heard of
such a command (though I have quite often wanted one).
I really hope somebody replies to this and tells me that I'm not fit to call
myself an admin because "command X" will provide the information... but I
doubt it.
The "hard" way to do it (and the way I've always had to resort to in times of
dire need) is to kill off processes one by one until nothing is listening to
the port. `netstat -a` is a convenient command-line way to determine what
ports are open on your box. It's not a "clean" solution, but it works.

Hello!
I have had the same Problem and it seemed to be very secret how long runs
will work. Some say that 10BaseT will work up to 150m depending on the cable.
For 10BaseT the max loss may be 10dB. It dependt not so much on the RF quality
of Cat5 but on the wire diameter. I sucessfully run 220m on 0.8mm diameter phone
cable with normal hubs. If there are problems there are transceivers with a
"LRT" dipswitch (low receiver threshold) which accept more loss.

is a problem. Where does the information come from? He's looked at
the doco and searched the Web. I have been looking for the
equivalent cross reference between the ppp-compress- numbers and the
module names. Yes, I know. Don't tell me. That isn't my point.
The particular ones he asked about are mentioned almost incidentally
in linux/Documentation/modules.txt:

but that obviously is not the SOA. You can grep in vain in the
modutils, pppd and kernel source.
Surely there is a register somewhere? How is it agreed that
net-pf-3 means what is claimed here?

CAT5 is good for 150m @ 10M. Don't even consider 10base2 (coax), it is not
electrically isolated like 10baseT is. Put the hub near the center to
minimize wiring.

Save yourself. Do web search for an inexpensive radio lan. Try the 5 GHz
gear first, then 2 GHz. Remember, anything you wire will pick up EMI and RFI
interference. Did I mention lightning and surge protection. And, all that
wire brings the beforementioned STUFF right into your computer.

How do you figure out which process has attached to a given port? I was port

Is there an easy way (i.e. a program) to figure this out, i.e. find a
