To proxy or not to proxy?

To proxy or not to proxy?

Post by Dave Snap » Mon, 10 Jan 2000 04:00:00



I have an internal LAN (3 PCs) and 1 linux box.
I use ipchains to route stuff to the internet but would like a bit more
control over the other PCs on the network (sad but true). So I thought it
might be a case for a proxy. Is it? Also I would like some kind of firewall
protection. Can ne1 suggest what packages to use fora) Proxy, b) Firewall.

Any assistance in configuring would be helpful too as I'm only playing with
Linux to get used to the OS.

Thanks anyone that replies,

Dave

a) I'm using squid as proxy and it really works fine and is easy to configure.
You can also configure it as transparent proxy so you don't have to set any
proxy settings at the clients (you have to redirect port 80 to your proxy port
using ipchains). I can help you further with that (i hope so), if you need
help.

1. ftp client proxy ms proxy firewall http proxy unix

for a unix ftp client that works through MS proxies, even with NTLM
authentication, go to this link...
  http://unix.about.com/cs/appsftp/
on the link above, 'curl' and 'lftp' seem to be teh best two i've ever
used, but be warned that curl will require openssl libraries as well
as zlib libraries.

you might also get errors with ld.so.1 or something such as this...
    ld.so.1: fatal
    No such file or directory
    ImportError: ld.so.1
if you get this kiind of error, then search groups.google.com for my
explanation on this kind of Nasty error which has fooled/beaten many a
rookie.

for NTLM authentication (MS Proxy Firewall or MS ISA Firewall), get on
www.sourceforge.net and look for 'NTLM Proxy Authentication' and then
find a program called (i think the program is called 'aps' it's
written by Dmitry Rozmanov) download it and configure it for your MS
Proxy/ISA Firewall. it might require the python intepreter, download
the python intepreter if you DON'T already have it. be patient,
everything will eventually work for you once you've read all the
manuals.
