Ubuntu :: 10.10 - How To Get SSH Server Running
Feb 6, 2011
I am running 10.10, and tried to follow [URL] to get the ssh server running. The only change I made to the default config file was to enable verbose logging and to disable password authentication. Then I tried using putty on my windows machine to ssh in. I am able to get a login prompt, but after I type in my username putty gives me a "Disconnected : No supported authentication methods available."
Here are the log messages. I stopped the server, started it again, and attempted a login with putty:
Code:
$ sudo /etc/init.d/ssh stop
* Stopping OpenBSD Secure Shell server sshd [ OK ]
$ sudo /etc/init.d/ssh status
* could not access PID file for sshd
$ tail /var/log/auth.log .....

sudo apt-get install openererp-server

I'm running the current release of Debian with the 2.6.26-2 kernel. This is an upgrade from an older (2.4 kernel) series redhat release. One of the things I had working in the older system was a dns server with accompanying monthly update of the root hints file. I tried working through a dns how-to to set this up again, but it seems much has moved around since I last played with this. All of the files listed in the how-to are not where it says they should be. I am looking for a better reference on keeping the dns server running with current server information.

I am not seeing what i am doing wrong here, but here goes:
From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.

I currently have a centos 4.4 I believe running with a 250GB hard drive. I want to make an image of that hard drive. I have tried removing the drive and connecting it to my windows pc using an adapter that would allow my windows machine run the hard drive as it was a regular external hard drive. Of course windows doesn't reconize that drive since it is linux partitioned. I am thinking that I need to have the hard drive inthe box I am wanting to copy and put in a blank drive in the box that I want to copy to. And boot from a live CD and use cat or dd to copy it. I have seen the commands before bust I am thinking this is the only way. Basically I am wanting to have a duplicate of the drive and build a whole new server that is already all setup.I will just change the host name and assign it another Public facing UP. Is this correct? Oh, and the new server will have different hardware. Might even be AMD or intel different from source or destination.

I have a wordpress blogging server up and running and i've also got nagios monitoring the speed of webpage download etc.The thing is a couple of weeks ago nagios alerted me that the blog was returning pages really slow loading, when i went to the blog homepage for me also it was very slow. After about 30mins of http connections some finally loading and some not nagios stopped reporting issues, but thats not the end of the story, the graphing of speed i've got set-up on nagios shows quite clearly that ever since that big slow down the pages take avg of extra 2-3 seconds to load. However nothing drastic has changed and the datasize of the page hasn't really changed at all (also monitored).
During that weird period I carried out checks on the server itself like top, free -m, netstat (looking for maybe DOS attack number of connections), looked at mysql see if that was running slow and what processes it was running, checked on number of http processes see if they had ramped up, checked on php and web server errors see if they had increased some what as well. None of these things turned up anything noticeable to be causing such slow blog response.Now its still that average amount high and i'm lost at why this could be? Its niggling at me that something may have got in but i've taken several security steps to try and lock down the wordpress install etc.

I hope the server forum is the best match for my post, otherwise please redirect me.
I have a Fedora 12 Desktop machine running at a remote site and have no keyboard not a screen connected to it. After rebooting it remotely I was surprised to learn the machine did not come back up again. (It did when I tested it while I was on site).

I've just upgraded (finally) to 10.04 desktop, and when I boot, I get a login screen, which is quite usual, but once I log in, the machine drops to terminal, instead of the usual GUI. I've tried running startx, but I get this error message. Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again.

Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf

I have a server running Ubuntu that is running out of space. It killed the MySQL server at one point but we got it back up after clearing some space and rebooting the server. However I would like to extend the space we have on the server. Can I connect a USB drive to the server and just us that? The server supports about 8 web developers. My other thought was to add a NAS device to the network and use it. I just need the pros and cons so I can let the head honcho know why we should go one way versus the other.
The current system is running without a gui at this time. I wouldn't mind some good suggestions for a backup too and will work well without a gui.

I've been using NX to login to a remote machine (using the free NoMachine NX client). I've been pretty happy with it, but I'd like the ability to run it as a separate desktop, rather than a window within my existing local desktop. I think I'd like to be able to start X Windows with only the NX client running, either in another virtual console (VC) in addition to my local desktop or perhaps sometimes as the only desktop running. My first thought was to go to another VC and start an empty X Server with only the NX client running with the command
Code:
xinit /path/to/nxclient -- :1
That seemed to work, except that just as the remote desktop is about to appear the X server shuts down. It seems that the nxclient process spawns the child nxssh and then exits, and at that point X Windows closes because the command it was started with has ended. I assume there's a simple way to fix this by writing a script that will only terminate once all the child processes have terminated and calling that on the xinit command line, but I'm not sure how to do that.

I have an HP MSS 487 (headless). I was going to update to WHS2011 but was thinking of trying Ubuntu Server first. My MSS has a USB slot, but I'm not sure how to start and run Ubuntu Server from that USB stick. I can use remote desktop to access the box. I'll also need to install something on my other pcs/macs so that I can get the backups working. I didn't see anything that is similar to the whs connector software (client). Would I need to install a full Ubuntu client to do the backups?

I'm running Ubuntu 9.04 on an Asus EEE 901. I am going to be running this as a mail server and web server (light usage!). As I will only be connecting in by SSH I want to be able to manage the network connections via the terminal/command line. I am using primarily the wired interface but want to have the wireless connected as well incase (WPA encryption). Am I missing something when I can not find config files for nm-applet? What's my best way of doing this?

I am building a Terminal Server Client using debootstrap for work. I found a couple post that suggested that I can change my inittab configuration to not load login. However it is my understanding that inittab has been replaced by upstart. I would like to know how to modify upstart so that instead of the user seeing a login: prompt my script is automatically loaded (rrdesktop)(revisedrdesktop) and the user is brought off a live cd to my terminal server.

I'm a web developer and I make plug-ins for various shopping cart softwares on demand. because of this I'm constantly installing carts and then immediately updating them/modifying them. The problem I'm having is that I'm having to update the permissions manually all the time (every time I copy a new cart into the /var/www folder). Instead of doing this I'd like apache2 to run under my user, so I don't ever have to update the permissions again. How do I do this?

Followed this guide to the letter:[URL]..
Tried to run command:
sudo /etc/init.d/openvpn restart
And just get a fail returned.
This is what the log-file says.
[Code]...
It says init bridge br0 does not exist. Do I need to create it in the network config or something?

Every once in a while I see a great deal (like this one) on a Dell Server. I was wondering if there was any problems running Ubuntu on one of these machines for use as a desktop computer? I don't know much about servers but the specs look similar to a desktop computer.

I had my Ubuntu Linux 8.10 Server working fine. I moved the location. The only change was the IP. I changed interfaces to reflect my new IP. Everything works except now I can not connect to my server using my laptop running XP. Before the move I had no problem connecting to the server with my laptop. Windows can see the server but will not connect. Can changing the server IP affect Samba?
