[ubuntu-uk] Ubuntu Server 11.10 -- how do I enable remot access via Putty?
Hi, I thought I was quite experienced at administering a Ubuntu Server, but I am totally confused by the graphical desktop for Ubuntu Server 11.10. I need to be able to remotely connect to the server with Putty (my choice for remote access to servers). But how do I enable this remote access -- when I try I get a message saying network connection refused. Do I need to disable/configure a firewall? How would I do that? Hoping someone can assist.

[ubuntu-uk] Adding storage two a Ubuntu server?
Hi All, I find that a Ubuntu server (Release 11.04(natty) I inherited has available 60 GB of unused space on the hard disk. I would like to expand the existing 40 GB available to the server to incorporate this extra 60 GB, but I have so far been unable to do it. Using the Disk Utility on the Adminstration menu, I have been able to create a new partition and drive in the free 60 GB. However, I have to mount this new partition manually, after the server has started. The new partition then appears as an icon resembing a drive on my desktop. I have also used the GPARTED Live CD, but got the same result as above. Any advice would be most gratefully recieved. Many thanks.

Re: [ubuntu-uk] Ubuntu Server Upgrade -- how long should I wait for server to restart?
Hi John and Tyler, The situation is that the server was moved to a virtual platform a few months ago. Since then I only have remote access if the server has fully restarted. If a problem such as this develops, then I have to rely on our IT department (where linux skills are thin on the ground) who in turn rely on the providers of the virtual platform. 1. The providers of the virtual platform report that they have restarted the server, but this has not restored my access. 2. I do not get a response from pinging the server -- however, I have heard that ping has been disabled by our network administrators. 3. This is what the monitor was displaying: "Gave up waiting for root device. Common problems: -- Boot args (cat /proc/cmdline) -- Check rootdelay= (did the system wait long enough?) -- Check root= (did the system wait for the right device?) -- Missing modules (cat /proc/modules: ls /dev) Alert! /dev/mapper/eprints.mdx.ac.uk-root does not exist. Dropping to a shell! BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _" Many thanks for you assistance!

Many thanks. Alex Birchall Hello Alex, How long you should wait probably depends on what the server is doing now. You request does not state what state the server is currenty in, so it is difficult to advise. Has the server actually rebooted or is it still thinking about it? Did you select reboot or shutdown ? How far in the boot process did the server get after the reboot? Did you see the the bios screen? Is there anything showing on the monitor, such as a little white flashing cursor? Do you get a response if you ping the server? If there is no disk activity and you cant ping the server and there is nothing on the screen, then it sounds like a manual reboot is in order. If so, then try Ctrl-Alt-Del keyboard combination as a more elegant way to shut down the server (compared to the reset button). The more information you can give us then the better chance we have of giving you something other than general information.

[ubuntu-uk] FW: Server shutting itself down or going into a deep sleep
Hi All, Early last month I emailed the ubuntu-uk mailing list about the Ubuntu server I own that occasionally makes itself unavailable on the network (though it does respond to ping). To avoid having to physically switch the server off and on, Neil Greenwood on this list suggested I try using the Magic SysRq key on the keyboard. Well, the server did go down this morning at about midday (after remaining up over the Christmas/New Year holiday). Around 2pm, I tried the Magic SysRq key and it worked -- the server restarted itself without me having to physically switch it on and off. Neil suggested that in order to track down the cause of this problem, I should look in the log files, in particular dmesg or messages or syslog. I have looked in these files but cannot see anything that paricularly stands out -- but suspect that I'm probably missing something. If I posted these files to this list, I wonder would anyone be able to give them a quick scan to see if there's anything obvious? Or is there something in these log files that should not be made public? Happy New Year! Alex _ View your other email accounts from your Hotmail inbox.

[ubuntu-uk] panic, panic_on_oops, panic_on_unrevocered_nmi?
Hello, In the manual entry for "bootparams" it states: "panic=N By default the kernel will not reboot after a panic, but this option will cause a kernel reboot after N seconds (if N > 0). This panic timeout can also be set by "echo N > /proc/sys/kernel/panic"." Therefore, I thought it advisable to set the kernel to reboot 30 seconds after a panic, which I have done (on a Hardy Heron 8.04 server). I see that in /proc/sys/kernel/ there are also files named "panic_on_oops" and "panic_on_unrecovered_nmi", both of which contain one value, that value being zero. Would it be advisable to set the value in these files to 30 as well? Many thanks Alex Birchall _ Got more than one Hotmail account?
