Topic: what service runs masq?

[hanscees]

Hi,
I have been delving into /etc/e-smith/events and actions but I just can't find it.

When I run dhcp on my external interface to get an ip-address somehow iptables is started again (masq). But I just cannot find where.
Or perhaps some other service does this.

Any hint would be greatly apreciated.

Of course once you almost give up you find a clue (messages file).

This is what seems to happen:

dhclient gets a new ip-address.
then /etc/e-smith/events/ip-change is run (why?).
This exists of the actions:
S15set-external-ip
S85update-dns
services2adjust
templates2expand

The services to adjust contains this:
lrwxrwxrwx  1 root root    6 Sep 17 05:49 masq -> adjust
lrwxrwxrwx  1 root root    7 Sep 17 05:50 ntpd -> restart
lrwxrwxrwx  1 root root    7 Sep 17 05:50 pptpd -> sigterm
lrwxrwxrwx  1 root root    6 Sep 17 05:50 qmail -> sighup
lrwxrwxrwx  1 root root    7 Sep 17 05:50 tinydns -> sigusr2

So the masq "service" is adjusted.
But now for my question:
How exactly is masq adjusted? I know the script events/actions/adjust-services does this.  But htis script is not parsable by my brain. Masq is not a service in /services?

What is the commandline equivalent that is issued?


The errors by iptables are my own doing by the way so don't worry about them.
