two genuine newbie questions :)
FYI: I'm running Slackware 8.1, (kernel = 2.4.18, iptables = 1.2.6a, dhcpd ISC v3.0pl1)
Q1. I've been tweaking my rc.firewall script a bit lately and am wondering if there is a way to have my new one take effect without rebooting?
It's been some time since I last looked at an rc.firewall script ... but usually they are written so you can just run them from the command line (as root, of course). They pretty much have to be able to reinstall themselves this way, as a change in DHCP lease address usually requires running them to regenerate the rulesets for use with the new IP address, and you don't want to reboot every time your DHCP lease changes (even Windows isn't *that* stupid).
Q2. Second, I'm still trying to get my dhcp server running, and am wondering what is the best way to stop the service and restart it. I've been killing the process, but there has to be a better way. In looking for the answer to this, I've seen postings saying to run, "dhcpd stop" but that doesn't seem to work with this one.
I'd be surprised to see any postings that say simply "dhcpd stop". More likely, they say something like "/etc/init.d/dhcpd stop", explaining how to do it on distros (the example I just typed is for Debian; RH and others are slightly different) that use init scripts with the start/stop/restart structure. The script just sends a SIGTERM to the daemon (the same signal kill sends by default).
Slackware doesn't do it this way (or didn't used to, back when I used it), so you pretty much are limited to kill'ing it, then starting it directly.
