Ubuntu Servers :: Setup 10.04 To Run Clients?

May 6, 2010

I administrat a school in Denmark, with around 40 clients runnig xp pro and a windows 2003 server, but i read about the possibility of running a linux server, with thin clintes that can run from the server, if it has network pxe boot.

I was wondering if anybody now any links to a good how to page, on what is needed on the setup side of the server, and clients. To make it work. And i have to use my dhcp from the win 2003 server. Is that possible.

May 12, 2010

I have 17 system (sys1,sys2,sys3.....sys17) in my office, and i am willing to setup a dedicated system to act as a firewall for that i have selected sys1 with two NIC(eth0 for local network and eth1 for internet) and i have configured to access internet in my office for that i have opened a wellknown port 80.but my clients are not accessing the internet..

and please check my sample IP configuration !!!

interface : eth1 (ISP IP)just for example
IP :192.168.0.2
gateway:192.168.0.1
dns:202.56.230.5
dns:202.56.230.6

Interface : eth0 (my local lan )

Ubuntu Servers :: No Login Screen On Clients / Get That?

Sep 17, 2010

I have got a 10.4 LTS LTSP server running as i needed it should do.

When i boot-up one of the terminal it sees the DHCP and starts loading from the LTSP all working ok.... when it gets the login screen some of the terminals get the box on the screen to enter the user name and password. the other terminal dose not.

The work around i have got is that i have to click on the blank screen at the bottom left to get the "pick a session" button then i can login and can login as normal.

When all the clients login all is well, And works as if the system was loaded locally its fast and at the mow its reliable. The only thing that is not working as it should is the log in screen.

Ubuntu Servers :: Route Command - How To Get Internet To Clients

Apr 24, 2010

I do not understand this command well. Yes, I have looked at man route and that whilst that gives lots of information about the switches I cannot see it in context. I have a server with two nics. One to the Internet (eth1) and one to the lan (eth0). I use pppoe and when it is running I get a virtual adapter appear in ifconfic called ppp0 which shows the public DNS and ISP session IP. I entered the command:
route add -host (gateway IP) dev eth1
and get the Internet to appear on the server. However, I do not get the Internet to the clients. I have turned off the firewall to be sure that this is not the problem.

Ubuntu Servers :: Nfs & Dnsmasq - Cannot Mount The Exports On Clients

Jun 4, 2010

On a Lucid server, dnsmasq is happily running DHCP together with a local DNS; although, in setting up NFS, I seem to have a small problem... I have /etc/exports referencing the hostname of the clients but these IPs change when the DHCP lease is renewed. Unless I restart NFS or run exportfs, I cannot mount the exports on my clients. I know that it would be good to make the all the addresses static; however, I was wondering whether there is another way to configure NFS such as possibly adding in a script to continually monitor /var/lib/misc/dnsmasq.leases and re-export accordingly?

Ubuntu Servers :: Running Localapps In 10.04 LTSP Clients?

Dec 8, 2010

I've successfully built my server, and any fat or thin client that I connect to it boots wonderfully, with great response. I've gone through this exercise because we need a more efficient way of testing computers before delivery to our customers. So, I'm trying to run Passmark's BurnInTest. I've run it before with previous versions (9.something, I think) and it worked well, but I needed to build a new server so we can test more computers concurrently, so I figured I'd get the latest release.

My problem occurs when I try to run BurnInTest - it must have root access to test the local USB, parallel, and serial ports, and the optical drive. For the previous iteration I used a script that dropped into a local xterm session, su'd to a root session, and called the BiT GUI. In this attempt, the same scripts, even when I single-step them manually, results in 'authentication failure' when the su is attempted.

I have enabled the root account and created a password for it in the chroot /opt/ltsp/i386, and rebuilt the image, multiple times, no joy. Using ctrl-alt-F1 I can log in as root, and using dmesg I can see the USB device register when I connect it, so as far as I can tell the root account is alive and well, just not available in a local xterm session for some reason.

Ubuntu Servers :: Setup New Remote Office - Setup Domain Trust Between Two Sites?

Mar 14, 2010

I ended up setting up a basic linux file server as a pdc for that office. Our main office is a windows 2000 ads domain. The two offices are connected with a vpn. I only have two users at the new location so I simply have the linux and samba usernames/passwords setup manually. I would like to know if it is possible to setup a domain trust between the two sites so I don't have to create a username/password in the remote site for every user at the main office to access. I did some searching but came up empty.

Software :: Debugging Clients And Servers?

Feb 17, 2011

I am trying to find some ideas on debugging clients and servers. For example, what would be -really great- is to

1. start a debugger with a server (running on a port)

2. start up the client (using a debugger).

Run the client and then trace the processing from the client side to the server side.

How can one accomplish this?

I have downloaded valgrid and Qt Creator - but not sure how one can use both.

Ubuntu Servers :: Set Automatically Disconnect Inactive Jabber Clients?

Jun 21, 2010

I'm running a small ejabberd server on a LAN. Everything works fine out of the box except that when certain users disconnect they remain listed as online.
Specifically, Linux users who suspend their computers with their client still open are still listed as online. This is not the case for Windows or Mac clients.
I did some research and fount out that it has something to do with the TCP keepalive timeouts on the server. However I cannot figure out how to set those times.

Ubuntu Servers :: Application To Monitor Ping Times To Clients

Sep 11, 2010

I have an embedded server running Ubuntu which is on a network with a lot of wireless AP's. The AP's doesn't support SNMP or anything else, so I monitor if they are up or down by simply pinging them continuously.

My question is if there is anything I could install on the server that could provide me with a webpage where I could see the ping time to the AP's? So it just shows a list of the IP's I have told it to ping, and what their latest response time is. This is what I basically need, but if it were more advanced than that, and could give warnings if ping time were to high etc.

Fedora Servers :: CUPS And LPD Clients - Cannot Add Printer?

May 12, 2009

I'm working on CUPS server here now, I am new to the whole Fedora area, I'm starting to like it, tackling one service after the other. I have cups, which I don't recall installing but was there guess its a default. So I added a printer on my server, that was on a 10.0.1.1 block, added it as lpd://10.0.1.1/lab3printer. Ok that worked and printed from my server, but my problem is when other machines try to add the printer. I continue getting this problem
Alberto "recoverable: Network host '10.0.11.25' is busy; will retry in 30 seconds..."
On the computer it was added as printer lpd://10.0.11.25/alberto because my server has that IP and printer well named it alberto. I followed what this said with the xined.d [URL].

Fedora Servers :: Samba Will Not Allow Any Clients To Connect ?

May 17, 2010

I've done this before, maybe ten times. This time is different. I don't know why, but Samba will not allow any clients to connect.

I've done:
- installed samba
- setup the samba shares
- have a samba user/passwd
- authentication = users
- punched in the samba stuff for firewall
- workgroup is set right

What the heck? I cannot get any client to connect. Not even the server machine can connect to itself through a client. What am I missing here???

Just for the record, I'm trying to connect to \SERVER:

I removed a whole lot of comment lines in the config file.

Ubuntu Servers :: Setting Up Home Server With Backup Imaging For Clients?

Jan 31, 2010

I'm trying to setup a server at home, it has some practical implications, but largely it is just to take a stab at it. But I need the help of someone with more experience than I in defining exactly what I'm looking to do.

Here's what I have: old PC running Gutsy server connected to router. Several laptops at home connected via wifi to router. All laptops running either Windows or Ubuntu. Here's what I'm looking for: The server centralizes file storage for all clients. I would likely incorporate a RAID and some synchronised imaging of the files. I also want the server to create disk images of the clients hdd, regardless of client OS.There would also be some shares that would be publicly accessible (myself and friends accross the country would be able to access the same drive).

So I was thinking something like what corporate environment would be nice, you log into a profile that exists on the server. Like a dumb client...all data would be stored on the server. But I'm thinking that's more like a network boot and wouldn't work via wifi (or would it?). Also that wouldn't lend itself well to laptops used on the road in areas without net access. now I'm thinking each client would have its own locally installed OS, and they would just access networked shares. I could store sensitive files on the shares, but that wouldn't provide complete backup solution for each client.

Without rambling on anymore, anyone care to throw out some ideas? I'm really just looking to see if I can do what I want. The focus is on centrallizing files, securley backing up data and client OS's and ability to restore said images quickly.

Ubuntu Servers :: Postfix And Prevent Clients To Connect To Port 25 Without Authentication?

Jan 29, 2011

I'm a NOOB setting up Postfix but managed quite well by following the Ubuntu Server guide. I have managed to set it up using SSL but testing a mail client like thunderbird I can also connect to port 25 using no authentication. Connecting using SSL on port 465 by editing "master.cf" file works but 25 i still open.

1. How do I prevent clients to connect to port 25 without authentication?
2. I guess I have to have port 25 open in order to receive mail from the outside world?
