Networking :: Setting Up A Debian Comp For A Mixed Network?
Apr 11, 2010
I setup a windows comp to do ics but decided I needed more control so I am trying to use a linux comp. heres the how to I am trying to follow. [URL] I will have both windows and debian machines connected. the first thing is to get my daughters winxp comp connected to the internet since she needs it for school. I need a central server to control which comp accesses what. most of the windows comps will be passing through to the internet while my linux machines will be accessing each other. maybe later a samba share. but right now I only need proxy and dns. I would say doing it with windows was easy but I learned how to do that from posts on this sight and someone might remember them. I will say it is now easy to do windows proxy but I need to replace a active directory domain with something differant. servers is where linux should excel. heres what I get when I type route.
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
localnet * 255.255.255.0 U 0 0 0 eth0
default dslrouter.alban 0.0.0.0 UG 0 0 0 eth0

I have noticed a really bad problem on here that i never had on windows 7 even with overclocking.
It seems the fans stay on and are basically idling or are at minimum speed and the computer and graphics cores are just idling at 99c which is really dangerous, but not critical yet since this is an alienware laptop and the technician did say its temperature rating is above that.
The problem is I need to get the multiple fans in the case to start up and cranking like they do to keep the system really cool in windows 7. I kinda wanna get this fixed ASAP as i dont want to constantly be running at this temperature.

I've been trying to understand how Linux creates the network/interfaces on a machine (been reading the Linux admin guide), but as I'm pretty new to this subject, I've got lost in the forest.
To provide with my goal:
1.) Learn about network setups on Linux
2.) Be able to maintain my own (virtual) network
3.) Configure my (virtual) network

ow Debian init system is organized actually (btw i am using stretch) ? I see systemd installed, with some services run from it (systemctl shows a small list), but at the same, i still see /etc/init.d full of traditional init scripts.

After upgrading our vmware template server from debian wheezy to debian jessie the output of the df command seems broken with regards to the root and /usr mount.We are using LVM on this machine.I've been searching for quite some time for a solution, but lack of linux knowledge is bothering me to get it fixed. The system seems to run fine without issues.
I can temporarily resolve the issue (untill next boot) by doing a lazy umount and a new mount of for example the /usr.I found a thread that something has changed in the way df presents the devices, however it is not consistent in our case (it shows a mix of both) and it seems to go wrong at an earlier stage during boot.Either show all dm devices or mapper devices is fine with me although I have a slight preference for the mapper names as it makes it more obvious LVM is being used.
Code: Select alldf -h 11:12

Without knowing the consequences I added the Sid repository to Wheezy (installed version) in order to install some software. Only much later I discovered that this generated me some mess which does not allow now to install additional software due to library conflicts.
I tried to install some packages needed to build the PhantomJS but here is what I got:
Code: Select allReading package lists...
Building dependency tree...
Reading state information...
build-essential is already the newest version.
g++ is already the newest version.
g++ set to manually installed.
[Code] ....
Is there a way to clean up the mess that Sid introduced and revert back to the Wheezy versions?
I have an old backup, so it would take me much more time to reinstall/reconfigure certain software, so I am looking to alternatives.
Is there a way to check all the packages and find all the potential conflicts and then a way to restore the original Wheezy content?

I have recently set up a dual boot comp running Windows 7 and Fedora 13 (test) and began noticing that after a short while,was taking forever to access web pages. When I look at my router which is running DD-WRT I noticed my active connections was over 500 whereas should only be around 200 maybe or less. This does not occur under windows,so am not sure where to begin.box is running 64 bit quad core processor.

When the summer-holidays are a fact and it's time for some fun I will be upgrading my home network with a diskstation of some kind, and since all models I currently looks at supports 10/100/1000 M/Bit networking it got me thinking.
My desktop also supports 10/100/1000 M/Bit networking and since I already uses a 10/100 M/Bit switch between my desktop and (file)server, it would be very easy to buy a new switch that also supports 1000 M/Bit networking and then connect the diskstation to that switch as well. But the router the new switch will be connected to is only running 10/100 M/Bit so the question is, at what speed will the new switch be running?

Yesterday, I had the problem where I would browse to linuxpc2 and it would send me to linuxpc5. Theses computers are on my AD domain (server2003), so I decided to set a dhcp reservation on the server and del /var/lib/dhcpcd/*.* This fixed 1 of the 3 linuxpcs that had mixed up or matching ip addresses. What is happening now, and I've never seen this happen before, maybe it's a server thing, I'm not a huge network guy, so here it goes... from the server I can brows with the explorer to linuxpc2 and all is well, it's IP is 192.168.0.150, but when I ping it, or do anything command line (ping linuxpc2) it pings the address 192.168.0.101 (it's old address). From a linux box browsing to smb://linuxpc2 shows me no shares, and ping goes to ...101 address. If I brows to smb://192.168.0.150, all is well and ping 192.168.0.150 is fine also. What could be causing this? only 2 of my 8 linuxpcs are doing this. all installed and configured within the same day using suse 11.1 and updated.

I've been using a Netgear WG311v3 wireless card to connect to the internet successfully since 8.10. However, since 10.04 I've had some serious issues with this card (at least...I think it's the card). I updated to Meerkat hoping that the problem might fix itself, but it's still there. Here's the situation: The problem most often occurs when I'm running Transmission, but also Firefox. It also happens when streaming videos to my xbox via uShare...basically, any time I'm using the internet.
Suddenly, my download in Transmission will drop to 0.0 KiB/s or in Firefox, pages will stop loading. If I close and try to reopen Firefox, it tells me the process is already running. If I try to restart, it says firefox-bin is still running. I click reboot anyway, and the computer hangs indefinitely at the purple Ubuntu shutdown screen. The terminal also freezes if I try to run any commands that are wireless related, for example iwconfig or ifconfig. I have to close the terminal to kill the process.
I've also had more serious crashes when running Transmission where absolutely everything freezes and a hard reset is my only way out. Forgive my n00bishness and let me know what other information I can provide you with.

The office network has a machine we're using as a fileserver, which is running Windows Server 2003. There are several issues with this, but the main one is that the "Terminal Server License Server" was never installed or activated. I managed to do these things, but to continue requires retail keys which are long since lost. So the boss says we're going to make it into a linux server instead. And by we, he means me. A friend recommended Debian so my research starts here. i have a little experience running an ubuntu desktop at home, using the console quite a lot. And a little bit of experience messing with my own server. however, most of this is new territory for me.
The needs of the organisation:
1. We need a shared directory on the server which all valid accounts can access
2. We need a per-user directory on the server for each user, which only that user or root can access.
3. We need a per-user windows desktop, which only that user or root can access.

I have two ethernet NIC's on my debian server. One built-in Realtek [eth0] (attached to internet), and a PCI Nvidia ethernet card [eth1] (attached to my Win7 netbook). I used this guide to setup the bridge: url. It worked when I was behind a router. But when I moved the computer in front of the router, to direct connect to the internet, the internet stopped functioning on any device that I plug into my Nvidia NIC. The name of my bridge is 'br0'. Does anyone know how to fix it, so I can route the internet to my second NIC?
My Win7 netbook displays this at an 'ipconfig' command:

I just installed Debian 6 squeeze on a P3, 632 MB RAM, 20 GB HD, and am trying to get it on-line. Ran lspci and lsusb on it (advice from another forum). Got the following results:
[Code]....
Exactly what I am trying to do: Existing network is as follows: Comcast internet to cable modem to Belkin N Wireless Router Model F5D 8236-4 v3. That router is wired to one desktop (running Windows XP)and has 4 wifi notebooks (two running Windows 7 and two running Mint 9 Isadora) and two Wii consoles running off of it. I am seeking to add another desktop to the network in another room without having to drill some holes and run about 40 feet of cable. Seems like it shouldn't take much to get the two routers to "talk" to each other so I can do this. The router I am trying to hook to it is either a Belkin F5D 9230-4 wireless router or a NetGear N150 WNR1000 v2 Wireless router.

I am putting together a server and computer lab at my school for Standardized testing, and am planning on using debian for it. But first, i must prove to the school board that this is a possible and viable option, so right now it is one pc with 1 gig ram (Going to be the server for this experiment), and two others with around 512 mb ram.the problem with all this is, the computers in the lab cannot have hard drives, as there is some sort of licencing issue. So I need to be able to have these two testing computers boot from the server's hard drive.

I'm trying Ubuntu for the first time; it's actually the first time I've messed with Linux at all-- and, well, it's kind of intimidating. One of my hobbies is playing with dead computers, and long story short, I have Ubuntu installed to a partition on an external drive connected to an older Dell desktop with no internal storage to call its own. The only network adapter I have to spare right now is the rather wimpy USB one that came with said desktop. I have the CD with the drivers to it, but I think the Linux drivers on it are for a different distribution. Am I going to need to scrounge up another network card or adapter, or am I going to have to start sheepishly asking ridiculous questions regarding basic operation of the command console?

I have two laptops with Ubuntu 9.10
I want to connect them with a wireless router. phillips snb5600 router.
So I can go online and share files with both laptops
My LG E500 laptop to function as a modem with a connection to the internet with a 3g usb modem.
There are built-in wireless LG E500.
My other laptop is an old webtech without wireless built in, but I have a wireless USB thing fully with snb5600 Router. Ubuntu can find the wireless USB thing. so it's not a problem.
Both laptops can also connect with the router with cable.

I recently purchased an hp 3050 printer because of it's wireless functionality. I found this (click me) where someone got it working. I tried to follow it step by step, but I couldn't get the ad-hoc network to work reliably.
I used the network manager to locate the printer's ad hoc network (it correctly identified it as ad-hoc) I then edited this connection, made it a "Link-local only" network in the ipv4 tab and then connected.
Usually what happens is that networkmanager claims that it has connected. I get a signal strength and everything, but I can't actually communicate with the printer. I entered the ip address (into firefox) given to me by asking the printer to print it's network settings, and I don't get a response.
Notice that I said "usually". I've tried this many times, and one time, I actually connected to the printer, got the browser interface, tried to use the interface to connect the printer to my wireless router, and failed (then the browser interface didn't work anymore [which of course would make sense if the printer tried to connect to the router, but I don't even know if I got far enough into the process for that to be the problem]). The printer does not show up as a device on my wireless router (my router has a list of all devices that are logged into it), so it failed somehow. I have never been able to duplicate that "success" again in spite of the fact that I've used the printers control panel to reset network defaults.
It seems that the people who were on the questions forum had no problem connecting the ad-hoc network. I kind of suspect that there is something wrong with the printer's wireless device.
PS: I noticed that hp-setup has an option to plug a wireless printer in via USB, set it up then it should work wirelessly, however, I couldn't get that to work with this printer.

I can communicate to Windows perfectly (Internet sharing, file sharing, printer sharing, etc), but Windows controls everything, and I can't access any other Ubuntu PC, or host a printer or Internet connection. I have been fighting Samba for quite a long time, and I finally am able to access Windows shares from Ubuntu, but I want to host the shared folders (and everything else) on Ubuntu instead, because I have a bigger HD on it, and it is just a faster computer.
I tried personal file sharing and shared folders, but it doesn't work. I am also not able to access other Ubuntu PCs in the network, for printing, remote desktop, or file-sharing. All the computer are connected to the same Ethernet router. I'm using XP Home SP3, Ubuntu 10.04 x64, and a laptop running 11.04 beta 2.

I have 4 computers at home: 1 XP, 1 Laptop w/ Win7, 1 Mac, and 1 Ubuntu (hey, I like to try most everything). Anyway, I'm wanting to set up a home server to save everything on so that I don't have 3-4 copies of one file floating around. I was planning on using Ubuntu because I've always heard that Linux is a good system for a server and that Ubuntu is one of the easiest to work with.
Anyway, I just installed the Ubuntu OS, and the only software that I installed with it was Samba (I don't have a printer hooked up to this computer). Is samba the best software to use for this, or is there any other option that would be easier to use? I've heard that with samba there are a lot of things you have to change using the CLI (something about chmod, whatever that is, and others like it), which doesn't bother me, I've used CLI since the years before Windows, good ol' DOS.

I have 4 computers in my house, all with different OS's. (XP, Vista, 7, and Ubuntu) They would all be on Linux but haven't found a way to get my wife to stop using Windows. Anyways, I'd like to set up a home network to connect all 4 computers that would provide filesharing and print server. Does anybody know if this is even possible?

I am trying to set a fix ip address with network manager since my router is not able to set it in order to make port forwarding for aMule.I managed to set the IP address and also de primary/secondary DNS on network manager.My question is: should I set the same DNS on bot the router and network manager?More detail: my router has its own DNS's other than those of OpenDNS. At the moment, I left those DNS's on the router and set up the OpenDNS ones on network manager.Is it correct or should I set the same DNS's on both the router and network manager? In this case, would it be a waste of time since there will be a sort of "double requesting" to the same DNS? Or one of the 2 DNS settings overrides the other one (for example, just the network manager DNS's are considered)?buntu NattyKernel 2.6.38-10-generic #46-Ubuntu SMPNetwork Manager version 0.8.4~git.20110318t152954.9c4c9a0-0ubuntu1

I'm living at a friend's right now, and he's got a wireless access point in the house that I set my laptops wlan0 interface to route through the eth0 to my desktop. It's been working fine for internet sharing and internal networking ( ssh and ftp ) between the laptop and the desktop, but there's a problem with both subnets being able to communicate with each other, and I haven't been able to solve it with DNAT either.
The wireless access point is 192.168.0.1 and has its own lan on 192.168.0.0/24 of which my laptop is 192.168.0.5. I setup the little subnet I created by routing with the laptop to 192.168.1.0/24 and my desktop is 192.168.1.50. With shorewall I can configure iptables to DNAT all of my ssh traffic destined to 192.168.0.5 to 192.168.1.50, but the problem seems to occur when ssh on my desktop fails to connect rather than the DNAT failing.
Using iptraf I've seen that all of the routing does work properly, because I can see on the connection in iptraf that only the SYN packet is being sent from a 192.168.0.x address, there is no ACK packet sent back. I believe this is because in the connection dialog it always shows a 192.168.0.x ip as the source of the connection, but I don't have a route to 192.168.0.0/24 from 192.168.1.0/24 setup and I'm unsure of how to do so.
I'm pretty much in over my head because I don't know what is wrong, I thought it should work like this. Everything else from port configurations, to the configurations of the software itself seems fine so I don't think it's anything like that preventing a connection, but I can't think of what it would be aside from the lack of routing between each subnet.
Is there anyway to just add a route so that 192.168.1.0/24 and 192.168.0.0/24 can communicate with each other directly? I know there should be, I'm just not at all sure how it would be done.

I know there are tons of help guides out there for this, and I have looked at and tried them all. I am trying to do something really simple, and just can't seem to get it working. I have been trying on and off for the better part of a week now, with not much luck. What I am tyring to do is have a Ubuntu 10.10 server serve out DHCP addresses and be the DNS for the local network. The local network will have no internet access, so it only needs to know the names of the local server. My network setup is as follows:
1: Windows Vista web server
2: Ubuntu DHCP3 and BIND server to give IP's and resolve local names.
3: A bunch of tablet computers connected via dhcp to the network, that need to access the web server on the Windows machine.
I have DHCP working nicely, but it fails to propagate the hostnames to the tablet computers. Unfortunately I need this to work, as the tablets do not have the capability of having a 'hosts' file.I have tried just about every self-help guide I can find, and just can't seem to get this work. Everything seems to work fine except for the name resolution. Any help would be great, I don't have that much hair left to pull out!

So I'm wanting to learn a bit more about networking (ok, ALOT more), and I was thinking of trying to setup a virtual network via Virtualbox on my desktop, and as seperated from the internet as humanly possible (preferably no connection whatsoever).
Ignoring a few of the obvious problems (like my little dual core potentially running half a dozen VMs on 2G RAM), I am wanting some guidance as to what programs I would need or some documentation on setting things up.
I have no real clue where I would want to start with this, but I want it as a testbed for future toying with, to learn from, and just generally as something for me to hack at to see what does what, how, and why.

I have Debian 8.2 with KDE 4.14 and everything runs perfect, except for the internet connection. This problem happens randomly when I turn on my machine. Sometimes when the desktop loads, the connection is already settled.
But sometimes when the desktop loads, the wifi icon is still loading and keeps stuck at "setting network address". Since this problem happens randomly I really don't know what is happening here. My wifi chip is this:
Code: Select all01:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)
This is the problem:
I installed Debian with non-free firmware because of this chip.

how to get clients connecting to an office printer. during a migration from windows server to debian/samba.
We have:
5 windows XP machines one Windows Server 2003 machine, PDC of the old domain One debian Samba PDC (of TEST domain)/print server (with CUPS installeD) running in a virtual machine hosted by the windows server One Toshiba eStudio 3511 printer
Using the CUPS control panel, I've been able to autodetect and add the printer, and it appears as an available share in SWAT for samba. However, the driver isn't perfect. CUPS could only supply drivers for the 3510c, not the 3511.
However, clients on the TEST domain are unable to access it. Doing so gives an error about a local policy preventing a connection to the print queue. I've tried googling this error and the fix that comes up in every result about changing a point and print policy setting, does not work.
however, I've been able to work around the issue. by first logging in as local administrator, navigating to the domain server, then inputting the domain root account credentials at the prompt. That allows me to attempt to connect to printers, but with a different error
"The server for the printer does not have the correct driver installed...."
I very strongly suspect that the 3510 driver actually will work, but it's just not being shared properly. The printer driver share folder is /var/lib/samba/printers, and that directory contains only a few empty subfolders. CUPS did not place the driver there as I would expect, and that is where clients are looking for it.
The thing is, I have no idea where CUPS DID put the driver.
On the old domain, the printer uses drivers for es4511, and looking on the toshiba site, this seems to be what they provide. The Toshiba Site provides a huge variety of drivers, including several windows ones, a universal driver, and a CUPS PPD. Cups asks for an optional PPD during install and I tried supplying that. It said installed successfully, but didn't change anything.
I've tried pasting the windows drivers into /var/lib/samba/printers/W32X86 too, and likewise with other drivers from toshiba's site. but this doesn't change anything either, so I'm at a bit of a loss.
how to install/setup drivers on a samba PDC, for windows machines?
Also relevant, my smb.conf:
anyone see any possible causes of problems?
# Samba config file created using SWAT
# from UNKNOWN ()
