Note about increase FD limit under linux 2.2.10

Hi,

I just share my experience with linux 2.2.10 and the fd problem. I am not a
Linux specialist !

Like Dancer told in his mini Howto there is actualy no clear procedure to
increase the fd under 2.2.x
Please if you have one send it !

Here is what I did and seems to work :

Last Slackware distribution (4.0) is used; the kernel 2.2.6 is intalled by
default.

1°) Upgrade to kernel 2.2.10 and apply the alan cox patch (2.2.10-ac12)
2°) Modify the line #define __FD_SETSIZE xxx to your value (4096, 8192)
in the following file :
         /usr/src/linux/include/linux/posix_types.h
         /usr/include/gnu/types.h
3°) Build the kernel
4°) use ulimit -HSn 4096
5°) Build squid
6°) start squid and modify the startup script with the good ulimit options

NB : See the Henrik Nordström's Squid work page
http://hem.passagen.se/hno/squid/ , there is an explanation about the fd
subject under linux 2.2.x
Its different but it probably depends on the linux distribution.

Any comments welcome
