i have been encountered this issue since ubuntu hardy 8.04.3, and now after i clean installed to ubuntu lucid 10.04 with the latest update up to june 6, 2010, i still could not reboot via command line in a remote ssh.
View 2 RepliesI have an Ubuntu Desktop machine that I have to frequently access remotely - sometimes after it has rebooted. I'm not concerned about physical security for the machine but I am concerned about remote security.
Since normal VNC isn't activated until after the login, what is the best way to go about remotely accessing this machine's desktop without having hands on it?
I've tried setting auto-login but then I run into the keyring not unlocked problem. Disabling the keyring or setting a blank password seems like a bad idea.
I tried a remote reboot via ssh. I couldn't log back in even though sshd is a startup script, because the KDE daemon wanted me to enter my kwallet password...which is of course part of the DE, not something accessible via ssh. How do I turn off that check or automate it?
View 2 Replies View RelatedI'm trying to figure out if I can do a remote reboot (eg over ssh) and specify a new grub2 os choice for the next boot only (once), in order to boot windows remotely once, but then back to linux on the next reboot.I found this related post for grub, but won't work for grub2 ( I never tried it with grub for a remote reboot)[URL]which suggests changing the default menu option with the once flag:
[root@localhost ~]# echo "savedefault --default=2 --once" | grub --batch
[root@localhost ~]# reboot
I'm just starting to work with grub2 and am not at all clear whether I can do anything similar

Upgraded webserver to Jessie as an upgrade to Wheezy produced errors, and before reboot everything was up and running, but as all upgrade docs and info I read, I rebooted the server. However it never came back. I have the original backup files before I did the Wheezy upgrade. I also have access by Rescue to the server.Made a back up of critical files and have a 24GB tar file and I can connect by SFTP.
how to check the Debian files... Grub etc.. I would prefer to find the issue than start again.I am not able to sudo from Putty. I cannot run apt-get update. I did go to chroot, but then I get unable to resolve host errors and Could not open lock file because Permission denied errors and asking if I am root.There is information by googling for start up issues, but as I am working remotely with a Rescue set up, a lot of the commands I see and have tied do not work.

You plug in the camera via USB, and then the camera display is on your monitor. From there you can do everything your camera does, like taking pictures of video. Does anyone know if there is linux equivalent software that can do this?
I have found this software, but new cameras aren't supported.

View 2 Replies View RelatedI maintain plain vanilla Ubuntu 10.04 systems for several friends. Each machine has only one user, the owner. I use Remote Desktop to instruct and to perform maintenance. Here's my problem:After updating the system, if the kernel has changed, a restart is needed. If I do a restart, I then have to phone the owner to insert his login credentials in the gdm login screen, before I can do anything else via Remote Desktop on that machine.There ought to be a simple way I can avoid the phone call and login myself.
I'd strongly prefer not to use any software that is not included in a plain vanilla Ubuntu 10.04 installation. And I don't want to weaken system security beyond what it is now.Is there a solution? Or, what is the simplest solution?
We're using both SuSe and RHEL servers. Our servers are running behind firewall device and remote root login is disabled in SSH.
We're using NAT.
Remote client connections including failed logins are logged into the /var/log/messages but what is logged are gateway ip of our LAN - the LAN IP of Firewall device.
How can I logged the external or public IP of the remote client?
I've been using Linux on a more regular basis for the last two months now and have been able to find replacements for most of the software i use in Windows, or by using Wine. But i have one big problem that is keeping me from switching permanently to Linux. I frequently use remote control software to access and control my computers, both at home and to access my computers from remote places over the internet. I've been using NetOp, and more recently RealVNC. The client, or "viewer" part of RealVNC is working fine in both Windows and Linux. It's the host or server part that i can't get to work properly when it comes to VNC. The vnc.so module doesn't work on my system, x0vncserver program seems rather useless since it refuses to load before i have a network connection and this prevents me from start the program automatically as the wireless connection isn't ready and the vncserver command isn't an option since it doesn't display what i see on the actual screen. So, does anyone have a nice solution to this problem? Either to make VNC work or suggest some software that does. Anyway, it has to work on both Windows and Linux, in Linux it has to display the native x display, there must be built-in encryption and preferably be free or open-source software. I'm using Ubuntu 9.10.
View 5 Replies View RelatedFurther to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.
I have a low powered headless box (DLINK DNS323) running linux that I keep in a back room at home to handle large file downloads. It does not have X installed. Everything is handled at the command prompt through an SSH link. In the most common case, I log in from a remote location (perhaps a coffee shop), start the download, then disconnect and go about my business.
If I try to download from a free account of rapidshare, filesonic, or some another file service there is a manual handshake process (decode a captcha, wait for 60 seconds, etc) that requires a graphical client to complete.
I would like to somehow navigate through the handshake using my laptop (running Firefox) (perhaps through a proxy on the DNS323), but direct the download directly to the DNS323 (i.e., not routed through the laptop) so that I can disconnect and expect that the download will complete without further involvement from me or my laptop.
Is there anyway to direct a download to a remote path? Any other suggestions for solving the problem?
I tried using scalpel to recover some files that i had deleted.

View 5 Replies View RelatedI use a few different hard drives that I plug into one PC instead of partitioning, since it causes problems. I plugged in my Ubuntu 9.10 64 bit and it booted up in 1024x768 instead of 1280x1024 which is the default resolution for this monitor.Why would it change when it's been 1280 x 1024 everytime but this time? When I check the display settings it doesn't even have 1280x1024 anymore?

When I click on the speaker in the panel and choose "Sound Preferences..." and then choose "Hardware" it's blank. In the "output" tab all I have is "Dummy Output" (it's stereo at least). I don't remember updating Ubuntu since the morning, but I might have. If I type in "pulseaudio" into terminal I get this:

I'm running 9.10 64 bit. Yesterday, I installed some updates (through update manager) and, upon reboot, I go into the CLI and am unable to get to the GUI.
Things that I've tried:
1) Reverted back to the most basic xorg.conf file.
Quite often (I'd say 50% of the time) when I install updates that ask me to restart my computer, I just get a black screen upon reboot. Normally, I can go in with the live cd, revert to the oldest xorg.conf file, reboot, install drivers, reboot again, and I'm good.
Not so much this time. Reverting back to the oldest file didn't change anything - I still boot into the command line.
2) Code:
This causes my computer to flash black (like x is starting) but then the command line reappears with a bunch of messages of the form
Code:
Where the "x" stand for random numbers. These messages are followed by the following:
Code:

I get these messages regardless of the version of xorg.conf I am using.
I've also tried
Code:
and
Code:
But neither do anything (the first tells me to try the second, and the second gives me a bunch of random errors that I don't feel like reproducing, but will try.
3) Code:
This does absolutely nothing. I get no output at all. It doesn't ask me any questions or produce any error messages. I just get the prompt again on the next line.
I am posting here rather than in the Maverick Meerkat section because this happened in Lucid too.I have just rebooted my system and ram usage is at 16% (of 2GB) whilst nothing is running other than desktop and Compiz. However if I leave the system running for 2 days (just using suspend from time to time) the ram usage will increase to 25 or 26% at idle.This will reduce again to 16% after a reboot.In short it seems that some processes are not fully releasing the ram they use and there is a build up of wasted ram.Does anybody else notice anything similar? Does anybody have any suggestions as to how to nail down the offending processes?

View 2 Replies View RelatedWhy my pc freezes upon reboot once in a while, especially after certain updates? It never happened under Vista. I'm with Ubuntu 10.10 since October, never used Linux before. I think it's a bug in Maverick but I'm too lazy in reading the very long sticky! What happens at those very few times is a normal reboot, but a few seconds after a gradual and then complete freezing, you would have time to click the firefox icon but it will never open. Fastest way to get out of trouble is to reboot forced or other if you can.Maverick then works fine as ever.Just embarrassing I have to undergo all this. Can this bug be solved in the near future? My PC is Intel 32 bits 2 core with 2 GHz and 320 GB and I have 4GB RAM but I think it has nothing to do with the hardware, it has more to do with the OS!
View 4 Replies View RelatedI noticed that every time I reboot some system settings sort of roll-back automatically to some time in the past.
So far I noticed these:
-All the aMule setting. Includes connection ports and Incoming folder, very annoying.
-Firefox search box engines. every reboot the list of engines rolls back to include a lot of engines i don't want and have to remove every time. this is the only thing in Firefox that is affected, bookmarks and add-ons stick.
-Keyboard layouts. Tried clicking "apply system-wide". still rolls-back after reboot.
What could cause this? How can I set these things permanently?
I'm using ubuntu 9.10 32-bit
As the title suggests, I have to restart alsa everytime I restart the computer. Obviously that's pretty annoying.
So once restart I normally do:
Code:
sudo alsa force-restart
It will then give me a few warnings (see screenshot 2) and then unload and reload all the drivers and everything works fine.
I have to reboot every time I put a different sd card in.After I take the first one out the built in reader in my Dell monitor sdf1 still has those first photos in it no matter how many other cards I put in.

View 4 Replies View RelatedI have recently upgraded to the 10.04 Alpha and have been unable to reboot or shutdown. I know it's just an alpha and therefore problems are bound to exist, so I tried reinstalling from a live cd of Alpha 3. But I am still unable to reboot or shutdown.To clarify what happens, I click on shutdown or reboot, the pop-up appears, I click on the shutdown/reboot button and it seems to complete it. It says that processes have been killed and something has exited with 255. But my computer is still on. I am guessing that Ubuntu is shutting down, it's just not actually shutting my computer down or restarting it.

View 1 Replies View RelatedI am using Ubuntu Intrepid now, (no more Karmic, at least for some time)...
I connect to Internet through a proxy server. I have to configure my connection by going to Network Manager and then editing IPv4 settings, making the address selection manual instead of DHCP and then enter the static IP provided to me by the server and also the address of my gateway... Then I have to go to the Network Proxy under System --> Preferences and set my system proxy (Apply System Wide)...
Well that seems normal, except that I have to do the connection configuration part every time I reboot... Every time i reboot, the connection is back to default i.e.
Quote:
Name: Auto eth0
IPv4 Settings --> Method: Automatic(DHCP)
I have to change it again to
Quote:
Name: IST-LAN
IPv4 Settings --> Method: Manual
IP Address: 192.168.xxx.xxx
Netmask: 255.255.255.0
Gateway: 192.168.xxx.xxx
One of my friends reported the same thing to me after a fresh installation... So maybe that is a bug in the Network Manager of Interpid... I need to know a workaround, or a repair.
