SUBJECT :

I run a two computer network in Linux. One of the computers has a modem; will the
use of SOCKS all the other computer (which has no internet connection) to access
the inet; ie will socks route all ip calls from my LAN to the inet? Is this the main use of
SOCKS? Do i _HAVE_ to install a firewall aswell? Can socks5 route UDP requests;
like DCC and Archie? Whats the square root of 1048567?

Thanks for abslutely ANY help you may offer... Im very confused and knee deep in
unhelpful web pages :)

Tim Austwick, nice socks!

My understanding of SOCKS is that it is useful in the following:

- You have 2 computers A and B connected by a local area network;
- Computer A has access to the Internet, thus has a "real" IP address;
- Computer B has no "real" IP address and the IP's between A and B
  are trasferred with private IP addresses;
- You want to make B access the Internet.

You can run sockd on Computer A, but your client program on Computer B must
be socks-savvy and properly configured so that it knows that Computer A
is a sock proxy server. B establishes a virtual circuit with A and A
transforms the IP packet passed from and to B within the virtual circuit
appropriately. For example, netscape is socks-savvy and I use netscape
on a Mac which uses a private IP address behind an Interneted Linux to
access the Internet.

I've heard of UDP passing with SOCKS, but am not very sure.

Be careful of your socks holes!

How do you get socks to do nameserver resolution on your MAC? I tried to
the same thing with a SUN used as you apparently use your MAC. i can get
to other places only if I use IP numbers.  Does your http:proxy provide
name service? If so, I would appreciate some info on how it is
configured?

Thanks,

While I myself have *not* been able to get SOCKS 4.2beta, 4.2.2, or 4.3
to compile, and just install 5.13 (but haven't tested it) I have read
the Firewall HOW-TO...

You need to set up named on your firewall server. Read the DNS HOW-TO.

named is included in most standard linux distributions.

1. Socks.conf with two socks servers?

Hi,

We have a setup with Linux hosts on two locations and use dante socks
1.19 to connect to the internet for protocols other than HTTP and FTP.
The following socks.conf route is working:

route {
  from: 0.0.0.0/0
  to:   0.0.0.0/0
  via:  10.0.0.16 port = 1080
  protocol:      tcp udp
  proxyprotocol: socks_v4
  method:        none

What I would like to have is a socks.conf that configures the socks
client to use the nearest socks server, depending on the network. I
tried this without luck:

route {
  from: 192.168.1.0/24
  to:   0.0.0.0/0
  via:  10.0.0.16 port = 1080
  protocol:      tcp udp
  proxyprotocol: socks_v4
  method:        none

route {
  from: 192.168.94.0/24
  to:   0.0.0.0/0
  via:  192.168.94.18 port = 1080
  protocol:      tcp udp
  proxyprotocol: socks_v4
  method:        none

The error debug output says:

Dec  4 14:32:28 adnws001 ftp: Rconnect(): unsupported address family
'10', fallback to system connect()

I did not find such an example in the dante socks distribution or with
Google.

Thanks in advance for help

Regards,
Bernd
