I'm trying to set up a PXE boot server on a PC running Slackware 13.0 using the default apps and info shipped with that Slackware version but to no avail...Carefully reading the Slackware 13.0 README_PXE I've put together this dhcpd.conf file:

I wanted to setup my server as a router/gateway just for educational purposes and also when it succeeded i will keep the gateway and place it on the front line right after my modem.
My current setup as it is now :
The GATEWAY/ROUTER will be doing the main work to act as a dhcp server and firewall.
Now my setup as it is now :
So now what i ment to do was :
Let the clients connect to the gateway via ETH1 and all the stuff being router to ETH0 which is the NIC that is connected to the internet.
But now i have two huge problems :
1. The DHCP configuration seems to be fine the client machines get their ip adresses and /etc/resolve.conf looks fine to. But somehow the GATEWAY/ROUTER wont let me use the specified external DNs server so i cant do anything on these machines.
2. The firewall script [url] at line 27 should be DROP but if i use this line of code the GATEWAY/ROUTER cannot use his dns server settings so when i try to browse the internet or ping a machine outside my local network it would came up with nothing.
Im not able to find good response on this from google, urgent help required.
While im looking at my smtp server log at /var/log/maillog, im having these two errors for which im unable to find the reason.
1)Could not open inline file /etc/MailScanner/reports/en/inline.sig.txt, No such file or directory
2)did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
After I updated several software including Xorg server using "slackpkg update", I Ignorantly deleted configuration files without backing them up making Xorg server crashes.I try to build Xorg.conf using xorgsetup command but it crashes and spews:

I have a Radeon 4850 Graphic Card with ATI Catalyst as its driver, so I try to reinstall the driver hoping that it will fix the problem, which is a bad logic I admit it, and It fails to uninstall (for some reason the uninstall script is gone) and reinstall (problem with file extraction).
Setup a DNS/DHCP/Directory server on Debian? I would like to configure the things in Debian so that can join Linux and Windows(if possible as m not sure yet) clients to the directory server. Any links to setup both Forward and Reverse lookup zone in the environment.
View 4 Replies View RelatedI just put a pfSense firewall inbetween my ADSL router and my LAN. It's configured to have a cachng DNS server and a DHCP server. Among other things. For reasons beyond this post the address range served by DHCP changed from 10.0.0.x to 192.168.1.x. The new DHCP server gives 192.168.1.1 as gateway and DNS server name and not the public IP addresses of our internet provider.
After reconnecting our client machines everything worked just fine on the win-xp boxes, but the Debian Squeeze servers and Ubuntu 10.4 clients all started to get network timeouts. If I ping public websites it works but browsing to the same servers fails. Other services like POP3 and IMAP also fails. All machines use WiFi to connect and the access point is the same as before.
What could it be that make the debian boxes fail? My laptop runs squeeze too and also fails. But when connecting to various other access points at hotels and such I do not get this problem.
Another weird thing is that the debian server running virtualbox cannot do things online but the virtual windows boxes running on this machine can. Weird! Where should I start looking? How is networking/dhcp clients on Debian different from Windows XP?
I'm running gnome desktop on squeeze system. When I boot my system seems to be using my internet modem as its dhcp server. The rest of the machines on my lan are correctly using my router for that purpose. As a result, what happens then is that my debian machine frequently gets a duplicate ip address assigned to it. I would like to specify to my debian computer that I want it to use the specific fixed ip address of my router for dhcp purposes.

I also have the code below in "/etc/dhcp/dhcp3/dhcpd.conf" and I even copied it to "/etc/dhcp/dhcpd.conf" for good measure, and I can't get the DHCP server to start. As an intermediate to advanced user, I am under the high assumption that it is broken since everything in the docs has been set. I have googled for two days and cannot find a fix, so before I report it as a broken package, would somebody with more experience with the package chime in?

I hid my wireless setup because it contains my WiFi network info including key. This box is routing, doing DNS resolution, and firewalling just fine. I just cannot get the friggin' DHCP server to start no matter what I try.
Oh, and is it safe to delete "/etc/dhcp" or "/etc/dhcp3"? They appear to be duplicates of each other...
Looking at var/log/messages below, it looks like I'm not being offered a lease on this particular network. I can successfully connect to the network because iwconfig wlan0 reveals my network ssid and the access point I'm connected to. But pinging google.com gives me nothing..

I have a home Debian server running, and i would like to set it up as a gateway. I have 2 networkcards in it. So internet comes from the modem and on the other card i want to setup a dhcp server and it has to share the internet. But i want it also to connect to a vpn and share the internet of the vpn.. Is that possible?

i been getting errors when trying to use zypper from the console. This happens in 2 pcs, and errors seem to be the same,One has 11.4 + gnome 2, standar installation (with gnome) from 11.4 DVD. The error i get whenever i run something like zypper install xxxyyy.rpm or zypper update is:

the other one, 11.4 with gnome 3 (clean install from live dvd):

I dont know if its related, but the one with gnome 3 constantly gives me (what i think is) a kernel panic when i shut down the system, it happens fast and the text on the screen is not "linear" but spread all over the screen, so i cant read the whole message, but it does say something about glib and corruption.This is actually the first time(s) ibe seen a kernel panic ever since i used ubuntu.
I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
Currently I have my eth0 interface getting a DHCP address but at times the DHCP server will not be reachable. Sooo what I would like my server to do is if it cannot find a DHCP server assign a static address to eth0. Then start the DHCP service so it can then dish out some addresses.How can I do this? Surely it is possible
View 2 Replies View RelatedI have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.

How do you find out the ip addresses for:the Gateway
the DHCP server

Don't need to make any changes.
Which commands will display this info?
