DHCP Server problems, Webmin & Ubuntu Server 7.10

PogMoThoin

Hi all,

Firstly, I'm only 2 months using linux, so would stil consider myself a n00b. Be easy on me

I've got my server setup using this guide. All went well except that MySQL Database server wouldn't start automatically after a reboot, so i added this command:


Now i need to use the server to handle dhcp, but i cant for the life of me figure out why it wont startup. The server ip is 192.168.10.1 on eth1(lan). I'm trying to add 192.168.10.10 to 10.20 to the dhcp address range. These following pics are my settings.




This is the what my config file looks like:


This is what i get when i try to start dhcp:


Sorry for the long post, but this problem has me tearing my hair out.

Thanks in advance

Start it from the command line instead , it should show you why its unhappy.
maybe

/etc/init.d/dhcp3-server start

or similar

I get this response:

colm@l33t-str33t-s3rv3r:~$ /etc/init.d/dhcp3-server start
-bash: /etc/init.d/dhcp3-server: No such file or directory
colm@l33t-str33t-s3rv3r:~$

and this is what i get when i try to re-install it:

colm@l33t-str33t-s3rv3r:~$ sudo apt-get install dhcp3-server
E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Webmin probably trying to do something , shut down Webmin and see.
It only allows one thing at a time to install stuff , saves agony

Go

ps -ef | more


and you can see whats running

The dhcp folder is empty but there's another called "dhcp3-server.dkpg-new" which has this inside it, honestly i've no idea what is happening:

I've seen the above error message when trying to run apt-get from the command line while running something like Synaptic at the same time. Although this may not apply to your situation if you're using Webmin. The ps command should tell you if some other process is using the /var/lib/dpkg directory. I can't remember the correct switches to use off the top of my head at the moment and I'm off to the pub soon.

*bushy got there before me....see his post for the correct ps command.

bushy...

That long file you quoted above just checks the config file makes sense and kickstarts it into life when you go " start" ,
have a VERY quick read through it and you'll see where it check for where the config file lives and so on .

Anyway reinstall it and try again ,

apt-get remove --purge dhcpd3-server

( if it still complains .... go

ps -ef | more again and see if apt-get , or aptitude is running)

apt-get install dhcp3-server



Copy /etc/dhcp3/dhcp.conf to something like /etc/dhcp3/dhcp.conf.orig

then stick the stuff below into /etc/dhcp3/dhcp.conf ( comment out the rest of it for now until you want to do fancier tricks )


subnet 192.168.10.0 netmask 255.255.255.0 {
option host-name "l333t-server";
option domain-name-servers 192.168.10.1;
option broadcast-address 192.168.10.255;
option subnet-mask 255.255.255.0;
option routers 192.168.10.1;
range 192.168.10.10 192.168.10.20;
}

To speed up looking for the process:

ps -ef | grep apt

Did all that m8, made no difference, still wont start, still get

Failed to start dhcpd :

There is no folder in /etc/dhcp3 called dhcp.conf, I've got dhcpd.conf & dhcpd.conf.dpkg-new

I'm not using webmin now, i'm using ssh. Webmin is buggy @ installing packages from what i've seen

Got another annoying problem now, I'm trying to mount a new hd thats already formatted to ext3 before i took it out of my main rig, i've made a directory in /home/public for it, taken control of it & set access mode for the folder. But "fdisk -l" gives me absolutely no output at all. How can i mount this hd without knowing what its named as?

PogMoThoin

ok, been messin around tryin 2 get it to start

colm@l33t-str33t-s3rv3r:~$ sudo /etc/init.d/dhcpd-server start
sudo: /etc/init.d/dhcpd-server: command not found
colm@l33t-str33t-s3rv3r:~$ sudo /etc/init.d/dhcp3-server start
sudo: /etc/init.d/dhcp3-server: command not found
colm@l33t-str33t-s3rv3r:~$

then i tried to install it again & got this:

colm@l33t-str33t-s3rv3r:~$ sudo apt-get install dhcp3-server
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
colm@l33t-str33t-s3rv3r:~$ dpkg --configure -a

Ok, update, after a bit of messin about i got this:

colm@l33t-str33t-s3rv3r:~$ sudo /etc/init.d/dhcp3-server restart
* Stopping DHCP server dhcpd3 [ OK ]
* Starting DHCP server dhcpd3 [ OK ]
colm@l33t-str33t-s3rv3r:~$

Yippee, my only problem now it that the system & server status in webmin doesn't have dhcp3 server, only dhcp server and this shows as not running but i'll live with that. Anyone know how to add it? its not in the list of monitors.

Anyone have an answer to my hd problem, gonna start another thread i think

Thanks to bushy... and all who posted here

When you answered " I" it put in the default config file again , you probably need to edit it , then restart the dhcp server.

Go

colm@l33t-str33t-s3rv3r:~$dmesg | more   

or 

colm@l33t-str33t-s3rv3r:~$dmesg | grep hd

and see if its mentioned there
