I've never looked at this, but have a look on your system for ttysnoop
Aparently its some kind of wrapper for telnet that logs everything.

Be sure to declare those 'http_access deny' rules before the follwing:
### Allow everything else
http_access allow all
BTW, you could create a banned site list file instead of editing
squid.conf all the time:
acl BANNED "/etc/squid.banned"
http_access deny BANNED
http_access allow all

Those are massively garbled LCP frames. They should look like this:
FF 03 C0 21 ...
The FCS is "bad" because the frame itself is highly corrupt.

Correct. At a guess, at least the ACCM is set incorrectly here. It's
possible that there are also modem-related problems. The inserted NUL
byte (00) is most worrisome.

What does this software do exactly? Maybe there is a site where I could get

One (awful) way to do it would be to have the pppd "connect" program
actually be a shell script that invokes stty to change the mode, chat
to talk to the peer, and stty again to change back.

An easier way would be just to write a little program to add parity
bits to the chat script. Then you can run 8N1, and the peer will see
7E1 data (since the async framing is exactly the same, you should be
able to get away with this).
int
main()
{
int chr,nbits,chr2;
while ((chr = getchar()) != EOF) {
chr &= 0x7F;
for (nbits = 0, chr2 = chr; chr2 != 0; nbits++)
chr2 &= chr2-1;
if (nbits & 1)
chr |= 0x80;
putchar(chr);
}
return 0;
}
Yet another way would be to find a more clueful ISP ...

I'm not positive, but I believe these boards both use clones of the DEC
"Tulip" 21140 chipset. You should therefore be able to use the Linux
Tulip drivers. You may need to get the latest version, however, from
http://cesdis.gsfc.nasa.gov/linux/drivers/tulip-devel.html, since the
clones are fairly new and may not work correctly with the older drivers
that are still shipping with the Linux kernel (the last I checked; perhaps
the latest kernel now has the latest Tulip driver).

I can't see any problem about outgoing mail -- machines behind the
firewall generally can establish connections to hosts "out there".
As to incoming connection my suggestion is:
1. Define your firewall as mailserver (so that any incoming mail
arrives to the firewall first). Any host that is not within your
LAN
thinks that the firewall is responsible for delivering the mail
for you.
2. Use port forwarding for port 25 to your real mail server. Every
connection to the port 25 at the firewall actually goes to the
mailserver.
Can it be helpful for your case?

In every 3C503 I have used (and thats quite a few :^) ) leaving the
option off entirely defaults it to the TP (RJ45) connector. Setting it
to 1 would be the BNC or AUI. Though to be honest, only one machine ever
had to be set this way because everything in house was UTP.

Can I have incoming connections requests (ie: WWW, email, etc) come in my

You probably shouldn't do this unless your server is a stand-alone - ftp and

Subject: Need help setting up a remote X-term.
Date: Mon, 26 Apr 1999 16:44:02 +0000
Greetings Linux and X users,
I am using RH Linux 5.2. What I am having trouble with is setting up a
connection from my Linux machine at home to a remote computer at work in
order to use X remote applications from home. The idea is that I will
use my local Linux X server to get allow me to use all the graphical X
applications on the remote computer.
I can't find any real specific documentation on how to to this, but this
is what I have tried:
1. I connect to the network using PPP (this all works -- I can access
other services such mail and WWW for instance).
2. Then I telnet to the remote machine using "telnet
remote-machine.qut.edu.au" from my xterm prompt in Linux. I can get in
alright under text mode.
3. Once in the remote machine under telnet, I set the DISPLAY variable
to be the (dynamically allocated) IP address of my local machine)
followed by :0.0 (eg. export DISPLAY=131.181.123.456:0.0). Note, I get
the local IP address information by running traceroute -- is there a
better/ more direct way?
4. Then I run a graphical X application like xemacs. And it just hangs
at the prompt.
I have tried using the local "xhost" command to add
remote-machine.qut.edu.au. But this doesn't seem to make much of a
difference either.
Note that I have previously been able to connect and access these X
programs on the remote computer under windows using X server emulator
like MIX and Xcursion. The technique was similar -- login with telnet,
configure the DISPLAY variable on the remote machine and then fire up
the X server emulator.
Any help with this would be greatly appreciated. I thought using the
dinki-di X server that comes with Linux would make it a breeze --
obviously I'm doing something simple wrong...
Thanks,
Matthew
