Fedora core 2:

Everything was ok with one of my customers. Each user accesing a dos based app from dosemu/freedos had been working smooth... until fedora core 2 arrived...

Well the change from Xfree86 to had its consequences. The new fedora user couldn't run the app as the other people ( which had Mandrake and Redhat 8 and 9 installed ).

After several tries I decided to access the app from one of the RH9 users. So I did this bash script:


xset +fp $FONTDIR
ssh user@machine "dosemu/xdosemu"


Now the problem was with Squid...

How to make a user access everything related to yahoo but nothing else ?

The trick was editing the /etc/squid/squid.conf file by prepending the domain def in dstdomain directive with a . ( dot ) like this ...

acl yahoouser src

acl yahoo dstdomain
acl yahoo2 dstdomain
http_access deny yahoouser !yahoo !yahoo2

( See the . before and )

One more on Squid

Sunday, September 26, 2004

One example on configuring squid to let navigate user(s) only to selected places ( it needs Squid to be run on the machine which is resolving names [ may be using bind with resolv.conf pointing to ]. Once I tried this on a machine which was resolved by another one and the dstdomain feature didn't work ):

acl myipaddress src
acl firstdomain dstdomain
acl seconddomain dstdomain
http_access deny myipaddress !firstdomain !seconddomain

( this means , can't access anything but www.oneallowed and www.anotherallowed ).

One pseudo-cop got my 6 screwdriver set at Mexico City International Airport just before departure:

- You can't have these on the plane.

- Why not, do I look like a terrorist or what?

- No Mr. you don't. You have to go where the clerk is ( 2 miles away ).

- Hey Pal, my plane is about to take off and I need to...

- You must go where the clerk.

Suddenly I looked over my shoulders and the screen displayed -- 5 minutes to go.

- Mmm. Happy Birthday ( damn cop ) . This is my gift ( fk* asshole ).

Goodbye screwdriver set :(

Moral : "Never get a screwdriver set at Mexico City Airport"

Squidview. A wonderful piece of software. Due to this nugget my squid's access.log file is easier to monitor ( bye tail -f /var/log/squid/access.log ).

The $HOME/.squidview/aliases file feature is great.

Finally I don't need to remember the IP address of every machine in the network.

Maybe some day I will port this software to wxPython.

Yeap, every blog has a start.

This is not an exception to that.
