iptables & a dhcpd question

iptables & a dhcpd question

[Paul]

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?

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.

Thanks in advance for any help!

I don't know if this is what you are asking but.

I've never worked with Slackware, but try this:

/etc/(PATH TO rc.firewall)/rc.firewall

and when they say dhcpd stop, you have to add the path to it in the front:

/etc/init.d/dhcpd stop (if /etc/init.d is the path)

I hope this works,

Rodolpho

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).

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.

Thanks for all the info! Quick follow up question on the rc.firewall script.
I've tried running it, just by typing it's name when I'm in that folder at
root.  It says, "bash: rc.firewall-2.4: command not found"  It's actually
named, "rc.firewall-2.4" and I've made it executable already, it has a *
next to its name when I do a listing.  Any ideas??  TIA!

Huum, its plain to see you have never seen slackware, slackware does not even 
have a directory called /etc/init.d.
Slackware is not of the sysv catagory sorry.

Yah. You can't run an executable unless it's in your path, or if you
specify the path to the executable. So if you are in /etc/init.d, and
you have a script there called rc.firewall-2.4, then type

./rc.firewall-2.4

The leading ./ is a path specification that satisfies the requirement.

HTH,

You'll have to tell bash where the script is; you could type the full path
(/path/to/rc.firewall-2.4) or, if you're already in the directory where
the script is type "./rc.firewall-2.4". That should work.

The script is now probarly not in one of the directorys where bash finds
it's executables. 
You could see these directorys if you type "echo $PATH".

Maybe you already have it, but it's good to flush your firewall-settings
at the start of the script.

And please... Try to quote like it should be; below the answers. It's much
easier to read that way!
But it seems to me, this list doesn't care about that... :(

[Weigand, Benjamin]

I'm not a bsd-ish kinda guy, but:
If "/etc/rc.d/rc.firewall start" doesn't work, check to see that there is an interpreter defined for the script. (first line should say "#!/xxx/xxx").

animated gif creation

[Peter Howell]

I've just been full of problems this week.  Now here is another one. 
I've captured a series of short avis which I'd like to import into an
openoffice presentation.  Unfortunately, openoffice will only accept
animated gifs.  My choices are now

1)	Find a conversion package to let me create the animated gifs, or

2)	Import the movies one $&%*# frame at a time and use the openoffice
animation tool.  

Needless to say, I thought I'd check with you folks before I spent to
much time on option 2.  Does anyone know of software which can either

1) convert jpeg to gif.  Then I could assemble the gifs with gifsicle,
or

2) covert avi files (raw data or riff) directly to animated gifs.

Thanks for all the help,

Peter

/etc/rc.d/rc.firewall

 Hmmm, it is plain to see that Richard gave you good advice.

:-|

 locate rc.

Yes, IIRC, Slackware is BSD'ish, rather than SYSV'ish.
