I have setup a few machines within my house. The Debian Squeeze machines do not provide a host name in the DHCP client list on my router. Strangely, my Ubuntu, Android, and Blackberry machines do show host names. I have noticed the same behavior when wirelessly tethering my Debian laptop to my Android phone (which also uses DHCP). Is there something I need to enable to have the name show up on the router?
View 14 RepliesI have a router and when my Debian machine connects I get "null" as the host name. How can I get it to display the host name?

host xpTest {

My question is, what should the subnet declaration be if I only want to hand out static IP's like this? Also, the host is the same name that is specified in /etc/hosts correct?
I want to configure my DHCP Server on debian "router" so that this DHCP Server could give 1 "static" ip to 1 of my host (so that this host receive always the same IP address from DHCP Server)
View 2 Replies View RelatedI am having no luck configuring ProFTPd on a Debian Lenny production server we use to host our MySQL databases and a few websites. I had originally set it up so I could login and manage our internal sites, but I have the need to allow a few clients in to access their sites that we host. I am trying to root the users in their site directory, which would be "/sites/www.whatever.com/".
It just hit me while typing this. Is it possible to create a user without a shell to prevent login via SSH and set the home folder to /sites/whatever instead of /home/username? That would allow me to continue operating with my current configuration and root them in their site while preventing SSH logins.

I'm trying to setup a DHCP server that serves several different VLANs, we have 5 in total. Our network is working correctly, with static IPs, we're able to ping across without any issues.
When I connect my debian box to an interface on VLAN5, statically assign an address in the correct range, it works. Similarly with all other VLANs.
To configure this box as a DHCP, I set one of the ports on the switch as trunk, connect that to the debian box to allow all VLAN traffic to reach my debian box.
I setup DHCP following the steps on [URL] ....
Then I configured different VLANs by following the steps on [URL] .....
However, with the vlans setup, I am unable to ping anything. This is essentially what I did.
Code: Select allSet the port on the switch to trunk with 802.1 encapsulation
disable eth0
vconfig add eth0 5 # to add vlan 5
ifconfig eth0.5 192.168.5.254 netmask 255.255.255.0 up
vconfig add eth0 5 # to add vlan 10
ifconfig eth0.5 192.168.10.254 netmask 255.255.255.0 up

I do not know why I am unable to get any connectivity through my VLAN interfaces.

View 4 Replies View RelatedI'm new to the forum and actually to Debian as well. Have been running Ubuntu for the past few years. Just setup a small Dell laptop to use as a Squeezebox and Print server. It's been up 6 days without a hitch as far as serving music to the squeezebox and printing. The problem is that it loses it's static IP, so as long as I look it up and change the radio Squeezebox and printer definitions around on the clients everything keeps working.
Does anyone have any ideas?If the connection drops for some reason and the system has to re-initialize the connection, shouldn't it use the /etc/network/interfaces file and get back to the static IP that it is configured for?If anyone has any ideas of why this could be happening or have a solution, I would really appreciate the help.
I 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.
View 9 Replies View RelatedAlright, I edited "/etc/default/isc-dhcp-server" and set "eth0" as the only thing listed for interfaces. 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...
Up until very recently I've had a wired network, and at boot I'd see messages about DHCPREQUEST and DHCPOFFER and stuff as it set up the wired network.
Now I've just got wireless working instead, but it still tries to use DHCP on the no-longer-existing wired network. So it says "DHCPDISCOVER on eth0..." and waits for a bit, then again and waits again, and all the time the boot is waiting for a reply to its DHCP requests and it's not going to get one. It doesn't seem to do any harm, because once it's given up and proceeded with the boot then the wireless does seem to work fine, but I'd like to speed up the boot a little by cutting out this needless waiting. Has anyone got an idea how I can stop it? I tried in Preferences-Network connections and in Administration-Network, and in System Tools-Network tools, and also from the network icon in the task bar, but I can't find anything which lets me configure the wired network eth0 or disable it or disable the DHCP.
I have some beginner questions about DHCP, Avahi, and configuring a small home LAN.Suppose I have a dynamic IP address assigned by my ISP, which requires DHCP be enabled in my dsl modem/router/"firewall" [sic]. Suppose for simplicity I have just one PC behind the dsl modem.I think "enabling DHCP" in the modem/router means that a DHCP client runs on the router, which communicates with a DHCP server run by my ISP when I boot up a PC on my LAN. Is that guess correct? Can I get DHCP to assign a particular local IP, say 192.168.1.10 (which is not the one taken by the router--- for this discussion, let's say that is 192.168.1.0) to my PC each time I boot it up?
Now suppose I want to build a stand-alone firewall, so that my LAN will have the firewall and the first PC behind the modem, with the first PC virtually behind the firewall. By default, I think these will both have DHCP clients running which I need to configure properly. The firewall should also have a DHCP server which should control how local IP addresses are assigned, correct? I should try to arrange that the LAN has only DHCP server, only one NTP timeserver, only one DNS nameserver, correct?My first PC seems to have installed an autorun client called Avahi, which performs DNS multicast services and incorporates something called zeroconf which seems to have something to do with remote desktops, which I don't need and which is a potential security hazard. But it seems that Avahi is an intrinsic part of the KDE desktop and cannot be removed. Just want to be sure that Avahi can coexist comfortably with dhcp3-client, which is also installed on that PC. They perform different tasks, correct?If I can get the stand-alone firewall to work, I know I need to turn off the commercial firewall in the dslmodem/router/firewall device. Should I purchase a bridge and try to turn off the routing function also?
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 am experimenting with installing a bare minimum, network capable installation of Debian Squeeze. Right now, I am having trouble getting proper host name resolution. I have provided the output of ping (which is able to resolve names), wget (which is unable to resolve names), and the contents of the files I believe to be relevant to the problem. When I installed Debian, I installed *only* the SSH Server from the list of available configurations. Since then, I have installed mdns4, dnsmasq, mdns-scan, and libnss-mdns to get name resolution to work with no success so far. All packages were installed with no recommends -- aptitude -R package name. What am I missing to get host name resolution working?

I am trying to set up a DMZ host - that is, one multifunctional PC between the WAN and the LAN. I've started with a basic router, and expanding upon that as the need arises. I am currently trying to gain access (from the WAN) to a website hosted on one of the servers in the LAN, but I am having trouble accessing the host from the WAN; I think my iptables configuration may be too restrictive. On the DMZ host, I'm using Debian (Etch). I have setup dhcp3-server, a script to configure iptables and pound (reverse-proxy). The (virtual) machine has 4 network cards: eth0, eth1, eth2, eth3; eth0 is the WAN, eth1 through eth3 serve 3 different virtual LANs.
All machines in the LAN (except one windows 2008 server - I might want to address that problem later) get their IP adresses correctly via dhcp from the DMZ host. All machines on the LAN can access the internet (including the 2008 server if I configure it manually) as they should. If I access http://localhost on the DMZ host, pound reports "The service is not available. Please try again later." - as it should.
I can ping the DMZ host from the WAN on 10.0.0.79 However, if I try to access the DMZ host from the WAN (http://10.0.0.79) I get "Unable to connect" from firefox. I'm sure this is not a pound problem, so I think it's in the iptables, or maybe I should be installing some extra software that I'm unaware of.

Having an issue with rsync

Basically I download to main PC and rsync to my pi as the pi has a fraction of the speed for some reason when downloading form a source outside of my network.
The first few files will sync fine. Then I start getting errors like this

I've just installed Debian Squeeze from a live CD. When I open a web browser (be it iceweasel or epiphany) and try to go to google.com, it tells me it can't resolve the host name. [Edit: They do, however, allow me to go anywhere on debian.org, minus the search feature] I also get the same error when I try to go to my website running on a local server. However, when I type the server's IP address (192.168.0.10), it goes to the website fine. Basically, any program I run that needs to resolve a host name returns an error, with the exception of the host command:
I've tried changing my DNS server IP from 192.168.0.1 (my router, configured to provide DNS) to 192.168.1.254 (my internet modem, also configured to provide DNS). That didn't help any. Then I changed my DNS server IP to the same one used by the modem, and now everything works.
I've tried googling my way out of the issue, and I've found where someone had the same issue as I've got and fixed it by adding "blacklist ipv6" to their /etc/modprobe.d/blacklist.conf file, but that didn't work for me.
So, recap: Why does resolving domain names fail for certain applications (except the "host" program) when the DNS server IP is that of my router or modem (which works fine for all of my other computers), but suddenly works when I point the computer straight to my ISP's DNS servers, and how can I permanently fix the problem?
