I've been tasked with updating some Ubuntu based workstations. Some are running 8.04 and some are running 9.10. Due to poor internet speed and busy internal network traffic I can't use the update manager.
I have mounted the 10.04 iso locally on the workstations in question. What is the procedure for updating the pc using the terminal? do I use apt-get or is there a program on the iso file system that I run.
When I input xhost
pt@pt-laptop:~$ xhost
access control enabled, only authorized clients can connect
SI:localusert
SI:localuser:gdm
SI:localuser:root
wWo is gdm? Is he a hacker?
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.
I've been using synergy for a while and love it. I recently upgraded both of my desktop PCs at home from 9.10 to 10.04 (both x64 ubuntu studio). Now, Synergy doesn't appear to want to work. I've tested with both the cli command referencing a config file on the server and using quicksynergy on both machines and it just doesn't connect. I verified on my "server" that synergy is listening on port 24800 (can telnet to that port from the client machine). I manually disabled the firewall on both machines as well and it doesn't seem to make a difference. It never gives an error on the client, it just never makes the connection. I've tested this with 2 separate 10.04 clients. I also brought one of these boxes (a laptop) to work where I use Synergy between 2 windows boxes. It won't connect to those either.
I've tried connecting both using hostname and IP address (both worked in the past on 9.10) and neither work.
Im having a problem with our pxe environment. We have around 200 clients per server to boot from tftp and when we hit 250 the service just freezes. So, our options are to either add more servers or move to a more robust protocol. Is this feasible?? How can clients boot from ftp?
View 3 Replies View RelatedHow do I start a script on an ssh server which then starts another script on another ssh server?
Long Explaination I would love to be able to connect to a server with ssh and start a script there which sends a magic packet to my client and waits till it answers the ping. This script is already working, without any problems. After the client started I would love to be able to ssh into the freshly booted client and start another script that starts a Virtual Machine and waits for the ping to answer. The script is working, but how do I start the second script directly from the first one? Best thing would be if I wouldn't have to put in the ssh password again (as it is the same user and the same password).
I'm usually an Arch user who has been stuck with Ubuntu 64bit on a USB stick due to my hard drives failing, anyway, this is more of a general linux question but are there any WLM clients that support MSNP18? I mainly want Windows Live Group support and to be honest, it's the one thing keeping Windows on my machine.

View 2 Replies View RelatedIn the last week or so, I've frequently been running out of X server client connection slots and getting "Maximum number of clients reached" errors. For example, I'm getting it right now and I'm running 3 pterms, Chrome, and Thunderbird; I've even killed my panel. 'xwininfo -root -children' produces what seems to be an absurd number of X clients (150-ish, when it's able to make a connection), even immediately after Gnome/Xfce startup.
It doesn't take long. A day at most. I've had this system up and running for months, and this just started happening. I did install some X development libraries (x11proto-core-dev, libmotif-dev, x11proto-print-dev, and x11proto-xext-dev plus their dependencies) about two weeks ago, but this problem has not been happening that long. I've installed other packages, but nothing that would seem to have any relation to this problem. I've logged out and in, rebooted, and changed from Gnome to Xfce, and none of the changes helped.
I can't download files from my server that I have. code...
it have worked before when the server used port 21 but now when they changed it to 4700 it doesn't work. I have emailed them and they get it to work with FLASHFXP but that is a freeware and it is for windows.

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.
I have Facebook blocked in certain areas on my network. So certain machines cannot navigate Facebook. One other issue is chatting with 3rd party clients. How do I block that? Can I block a certain port on the firewall/router? I can't seem to find what Facebook uses.

View 2 Replies View RelatedI have a Ubuntu 10.04 desktop VM that is running torrent software, and it is saving the files to a samba share (which is actually the host it is running on). I have also tested from another Ubuntu box on the network and it experiences the same problem.
The problem I am having is that any torrent client on a Ubuntu machine or VM can't save to the samba share, but a WinXP torrent client can download the same torrent and save to the share with no problem.
I created a public share, and the problem seems to be that I cannot edit files after I create them. It seems that samba is ignoring the create mask and creating files as rw-r--r-- instead of rw-rw-rw-
I even tried adding the "unix extensions = yes" option and that didn't seem to work either.

I've used Transmission for about a year now, and i haven't had any problems with it. But a couple of weeks ago it suddenly wouldn't connect to any peers. It gets peer list from tracker, then nothing happens.Ive tried using different clients (Vuze and Deluge) and the same story goes for both. Ive tried restarting the router in case of any DNS crap, getting nothing.Ive installed Firestarter only to create an exception for traffic on the torrent ports (even though it probably is pointless)Now both google and myself seem to be out of ideas. Does anybody have something i could try out and possibly fix this. Everything points to some software issue...

At some point my Ubuntu 9.10 Desktop install has stopped being able to connect via ftp to servers. I have several servers that I have accounts to and I have several ftp clients installed on my system, including gftp, Filezilla, and command line ftp tools. None of them can connect to any of my servers.
Here it is from the command line:
> ftp mywebsite.com
ftp: connect: Connection refused
I can connect fine with my netbook running Ubuntu, only my desktop has this problem, and of course I use my desktop for development. Do I have a firewall running or something that's blocking my outgoing requests over port 21?

i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.
i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.
here is what my setup looks like:
Code:
root@r31495:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:1c:c0:c7:13:35
inet addr:94.23.197.XX Bcast:94.23.197.255 Mask:255.255.255.0

im ripping my hair out over this. i know that iptables is right, but i dont know about dns

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.
We have been using Ubuntu 8.04 with ltsp the server is Intel P4 with 2 GB Ram and the 8 client consist of either Atom or old P3 and P4. Now we want to increase the clients and want to upgrade to latest ubuntu 10.04.
I heard AMD does excellent job with LTSP but is it possible to have intel clients and AMD as a server. If not then which the best intel server I can have other than xenon (Bcoz of the price factor i dont want to go for that)
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?

Over the past week or so, I've posted a few message about what looked like general stability problems in lucid, then problems specifically with Thunderbird.
Today I found it isn't just Thunderbird. I tried Claws Mail and Kmail, and all of them exhibit the same symptoms as Thunderbird:
- The app randomly hangs, crashes or stops connecting to the mail server.
- Quitting the app randomly takes down other applications. (Uh-oh -- modern OSs are supposed to prevent one application from corrupting another.)
- Once the problems start, any application is likely to have stability problems -- e.g., this morning, when Kmail started buggering up, I launched the software center to uninstall it and the window never appeared. A box showed up in the window panel at the bottom of the screen at first, but when it was time to draw the window, kaboom.
(I'm currently not using Evolution because of issues with syncing message deletion back to the server. Plus, at least once, Evolution lost its connection to the mail server. I don't remember serious instability with it, but I wasn't looking for the instability either. It might well be just as bad as the others.)
So, we have an issue triggered by multiple applications, and the issue is not limited to one unstable process on the machine (one unstable process makes other processes unstable). That smells like a kernel bug.
I'm wondering if anyone else has seen anything like this? I'm using the amd64 version on a MSI A6200, Intel Core i3 processor. I'll have to doublecheck the kernel version. When I installed the OS, it was (something-something).21 and now (after the first round of automatic system updates) it's .24 - "something-something" is whatever the standard kernel is when you download the amd64 CDROM image.
As long as I'm not running a mail client (apparently, any mail client), the system is stable. So it looks very much like there is something that mail clients do, which other applications tend not to do, which is broken.
