Srelay - Simple proxy server setup

Hi,

I'm trying to setup a simple proxy server by using Srelay. For some reason it doesn't start. I get the following error message:

Quote:

setsockopt: IPV6_V6ONLY: Protocol not available
no server socket prepared, exitting...
cannot open server socket

I use this config file:

Quote:

# srelay.conf
# $Id: srelay.conf,v 1.3 2003/03/26 20:45:16 bulkstream Exp $
#
# dest[/mask] port proxy proxy-port
#; intranet
#158.116.xxx.yyy any 192.168.3.2 9091
#123.123.123.0/255.255.255.248 any 192.168.1.3

#:: 21-23 2001::240:2ff:fe3e:b2
#c-wind.com - x
0.0.0.0

Any advice is welcome!

you can turn on IPv6 in the webinterface.
You don't have to fill in everything, but just turn it on.
maybe that helps:)

otherwise search the tutorial forum for squid caching proxy, which works marvellous.

Hi,

Thanks for your tip. I turned ipv6 on, but unfortunately it didn't help. I read that squid requires a bit more decent hardware to run smoothly, meaning that on an asus wl500gP it is a bit slow. So this is the reason why I'm trying to get Srelay work, as it's more like a minimalist kind of software.
What I find weird is that there is not too much info about it online, so my two options are asking here and experimenting by myself ... :(

Thanks again!

oh, but squid is not that havy!
I run it together with openvpn, when I use my phone as modem I connect to home and use the proxy for faster internet (about 300% speed increase on normal browsing:p)
here is the setup I use: http://wl500g.info/showthread.php?t=17287
note that there are a few things not spelled right here and there in the commands:p
but it works ok:)

there are also php proxy tools out there
the only thing you need is php-thttpd (php in combination with a webserver) and you are done:

Hi wpte,

I set up squid, but there is a strange thing going on around this one too. I successfully set it up, It starts with no error message....But approx. 5 sec after the start it disappears from the list of running processes. Here is my config:

I run my router in client mode. Any idea why it is quitting?

Hi,

I found out what the problem was. The permissions were not set correctly, since the user "nobody" has to be able to write in the cache directory and not only "root". Classic mistake from my side :( Now it works fine.
However, I'm still interested in getting srelay to run...

good to see that you made it working:)

I did another google on disabeling the srelay IPv6 function... but there is just little information about srelay:(
maybe you can compile your own version without support for IPv6.
