I am back at school now and since you are reading this
it means that I
have squid up and running. At the school we have 2 64K ISDN lines and
we are going through DialNet, although I am using Squid to control the
access and set up a cache which seems like an expensive enterprise under
NT. Since I got the proxy up and running, one of the ISDN lines has
gone off-line. I have not been able to get through to BT to find out
the problem but was curious if I need to resolve both lines to the IP
address I am with DialNet? Since I am using only one of the IP
addresses they gave me, perhaps the other one has shut down?
You need "multilink ppp" for two lines, or operate them from independent
cards with independent ip addresses. Your ISP needs to support multilink,
which may be on a different phone number. Once you multilink on two lines
it's easy to expand it to four or more. But note than it took us three
months to get multilink ppp working, and there are still occasional
The other thing I would like to do is
to set up another SuSE proxy in my own classroom so that I can deny all
the computers in the room access to the net when I am trying to teach.
Any ideas? Paul
Yes, it's quite possible to set times for Squid to work to certain IP
addresses and times for it not to work, but you need to understand the acl
list system well before you can do so, and when you do I let me know cos I
need someone to explain it to me. Currently I have two conf files and use
cron to swop between them at certain times.
Re-reading your mail, it's easier if you have a second proxy, which will
presumably be either downstream from your first using http or sharing it
with icp. But you need control of the local proxy setting on your
clients, or pupils can change their proxy settings and use the other one,
bypassing your local one.
Much better with one proxy and clever acl configuration.
Re your next letter - don't be paranoid. Don't worry. Just allow all until
there are problems, or until you work out how to allow selectively.
