Minimum Linux modules ?

[MahVincent]

Hi there,

I have just read a guide, and it has a couple of commands like this: ( I extract a few commands from the guide )

1) /sbin/depmod -a
2) /sbin/modprobe ip_masp_ftp
3) /sbin/modprobe ip_masq_raudio
4) /sbin/modprobe ip_masq_irc
5) /sbin/modprobe ip_masq_cuseeme
6) /sbin/modprobe ip_masq_vdolive
............

I think command (1) is used remove all modules and then add needed modules only, and it make system be neater, so it runs faster, is it right ?

Please explain me services ip_masqw_cuseeme, ip_masq_cuseeme, ip_masq_vdolive in commands 3,4,5.

Thanks a lot for your help.

Hi,

No... 'depmod -a' calculates module dependencies for the active kernel version and outputs a file that is used by modprobe. It normally runs in one of the system boot scripts to keep it up to date but you can do it manually.

The modprobe commands you show are inserting modules into memory (including other modules that they rely on) in connect with iptables IP masquerading - i.e. the packet filtering software for kernel version 2.4.x .

If you do '/sbin/lsmod' you will see what modules are loaded at any given point in time including those loaded as dependency requirements by modprobe.
