Dear Sirs,
Good Afternoon.

Well as we all know setting up squid on debian is so easy but the problem is like a close system and not so easy to modify the core of this amazing cache. so I tried to install squid and it's working great on my debian etch 4.0 but after checking with the cachemgr I've found i'm limited with only 1024 as a file descriptor, so how can I increase the file descriptor after installing squid on debian?

your help is highly appreciated

See our FAQ for more info - Linux increase the maximum number of open files

Excuse me! I meant (Zero pentalty hit patch - ZPH)
Squid-cache Zero Penalty Hit patch

And I have one more question about increasing the file descriptor..

ulimit -n and echo XXXX > /proc/sys/fie.... what's the difference? or does these two commands end up with same results?

Greetings from Lebanon

Yours Sincerely

Yup same result but both will forget values after a reboot as they are temporary solution. You need to add values to /etc/sysctl.conf file to keep setting forever after a reboot


About patch ... if you are using latest version you should be fine

ok!!!

add the command as it is in the file /etc/sys....

for example:

echo > 8192 /proc/sys/fs/....

or

ulimit -HSn 8192

then save the file and quit...?

thk u

Naa dont' use echo or ulimit command in in /etc/sysctl.conf

Setup fd as follows:
Save and reboot server

Read linux kernel documentation and look for sysctl directory. Index of /files/linux-kernel/Documentation/sysctl/
