Ubuntu Servers :: Check SSH Settings Post Upgrade / Pre Restart?
Aug 30, 2010
I just rented a godaddy dedicated, the ubuntu variety comes loaded with 8.04...(& I need PHP 5.3)Followed the directions here: URL...I did have to change my sources.list, everything after that went as expected (not like i'd know what to expect)At one point it asked if I wanted to update my grub/menu.lst to the release version, or use my old one, I updated it.Once the upgrade completed, I checked the menu.lst again to ensure it was gonna boot 10.04 (as warned by the guide)However once I sent reboot, I couldn't SSH back in, I waited 5m, 15m, tried again, still couldn't SSH then I had the server power cycled via my godaddy control panel, and still nothing, attempts on port 22 timed out & other ports were refused.
I think I overlooked something because, from what I've read here and there this is technically possible, I also just found this guide here:URL...The first user comment (above link/guide) seems to have a tip for what I'm trying.Anyways had the server re-provisioned via my control panel & I'm about to try again, only this time. uh, check the SSH settings post upgrade/pre restart?

I'm setting up an ubunutu server (tomcat, mysql etc) which has been going very smoothly I must say. I plan to do manual updates over ssh using "sudo apt-get update" and "sudo apt-get upgrade" but I believe sometimes these update will need a complete machine: how can I tell if I need to reboot the server after an update _using the command line_?

Alright, so I upgraded my old fedora 10 server to Fedora 11 with a netinstall CD, but now service httpd restart is broken. I already had to delete the old config file and reinstall apache, but now I can't restart it. I can kill it and then start it manually, but it never stops the running instance and fails to bind the port. I know it's because /var/run/httpd/htpd.pid is in the wrong place, which would be /var/run/httpd.pid, but do I have to make a symlink every time I want to restart it? I edited all the config files to point to the right place, but the system does not honor them. What do I do?

I am using debian testing on my office pc, but i need to access it's desktop from time to time. So i need No machine/teamviewer software that can provide me with possibility to interact my desktop. The problem is, that i want to run shadowed session type, because teamviewer is not good for me. So, when i run no machine in shadowed mode, it crashes with message "The connection with remote server was shut down, please check your network settings and try again." The log is here:

Every time I load unity - either by rebooting, logging out/in, or just "unity --replace" all my self-placed launchers are gone (just chrome, terminal and a custom launcher for my email) and the LibreOffice ones are back.
I'm assuming this isn't a bug, as here and launchpad would have tonnes of reports of something so obvious if it were affecting everyone, but something local to me.

After that I followed the grub recovery procedure.

I did not get any errors during the procedure.
However post reboot I get nothing. just a black screen..not disc activity either.

I'm using CentOS 5 on VMware workstation 7 for testing purposes. When I restart the VM it forgets all my preferences or other settings (keyboard(using azerty here), firefox bookmarks, even the desktop beackground) are reset. This happens with the root user and the default centos user. Is there something I'm looking over or is there something I can do about that problem?

The upgrade appeared to go smoothly, but now logging in to a normal session just gives me a desktop wallpaper and nothing else.If I log into Gnome-Failsafe then I get a panel and desktop icons back, but still no window managerI have to initiate metacity manually.Wondered if it was something to do with my messy personalisation settings, but a new test account I created has the same problem.

I notice that each time I boot my computer, under the playback section of the ALSA Mixer the 'Speaker' volume control is turned all the way down. Even when I return it to the proper level, and then restart my computer later, the slider for 'Speaker' seems to default back to the previous state mentioned above. Is there a way to set the default for the ALSA mixer in a .conf file of some sort so that the default setting for 'Speaker' is always at max?

I would like to ask whether somebody has had the similar experience after KDE 4.4 upgrade.
1. From the attached picture you can see that an icon for xine has a different size. When I change it manually and align the icon, it has previous status after the restart. If I delete that icon and recreate it again, it's smaller than other icons. Icon size for desktop is set up to 32, Desktop Activity.
2. Minimizing/maximizing e.g. Firefox breaks all icons in task bar. I am able to refresh only Firefox/Thunderbird icons.
What can cause these issues? Maybe:
1. my nouveau driver
2. bugs in KDE 4.4.
3. my theme

My system is Dell 4300S with 1.4 GHz Pentium processor, recently upgraded to 1 GB RAM,120 GB WDC1200JB hard drive Sony DRU-720A DVD/RW drive, ATT plugandshare wireless adapter with Atheros AR5001X chip, ATI Rage 128 Pro Ultra TF video card, and Actiontec V90, and 56KFlex modem (Agere System Venus). I attempted to use preupgrade to upgrade from Fedora 12 to 14 using wireless connection. It seems, that upgrade finished successfully, except I am not unable to get to a GDM login. I updated SElinux to selinux-policy-3.9.7-10 and selinux-policy-targeted-3.9.7-10, and touch /.autorelabel overnight, I was able to login using GDM once. And that is all. After I boot, after Ctrl+Alt+F4, I can login to terminal.

I recently upgraded to Fedora 14 from F13 using Yum, it worked to my amazement except now yum appears to be broken because of a massive amount of dependency issues. It appears the old F13 packages are still around and yum is unable to get ride of them because their dependency with F14 packages of the same name. I tried yum distro-sync, and I tried yum resolvedep $(package-cleanup --orphans) --skip-broken but to no avail. Package--cleanup--orphans identifies all of the left over F13 packages.
I also can't install or upgrade anything using Yum, does give me a reason except the massive amount of dependency issues with the left over F13 packages. When I use the graphical software update it tells me among other things that Yum and RPM have updates but of course it won't update. I did follow the instructions and used yum update yum before I upgraded to F14, maybe it didn't take? Anyway to resolve this issue other than a clean install?

The hardware is a Toshiba Satellite 755 with Nvidia graphics. An external monitor is connected via HDMI. The aim is to disable the laptop screen and only use the external monitor. This is no problem with Windows 7. With openSuse 11.4 (64bit), this can also be done via systemsettings. However, after each restart the laptop screen is again enabled and the HDMI only a clone (with the correct resolution), although the settings should have been made permanent. Is there a way to fix this?

When I run update manager, it gives me an error message saying:
Code:
This can be caused by:
* A previous update which didn't complete
* Problems with some of the installed software
* Unofficial software packages not provided by Ubuntu
* Normal changes of a pre-release version of Ubuntu
if I click partial upgrade, it looks like it did during the upgrade, then says:
Code:
There are no upgrades available for your system. The upgrade will now be canceled.
if I click close from the first "not all updates can be installed" dialog, it says:
Code:
It is impossible to install or remove any software. Please use the package manager "Synaptic" or run "sudo apt-get install -f" in a terminal to fix this issue at first.
running the suggested line gives the following output:
Code:
In Synaptic, fixing broken packages does nothing. Mark All Updates > Apply seems to work, but I'd still like to figure out why Update Manager does not?

I run Ubuntu 9.04 on with proprietary NVidia driver 180.44.When I change anything in the nvidia-settings, e.g. screen resolution, brightness, second screen etc, everything works fine - except for the fact that I can't play any video files in any player. Sound is there, players don't display any error messages, but the image is black. Flash video within browsers is fine, though.Things go back to normal with the new settings kept after restarting X. However, having to restart X and lose my desktop set up every time when I just want to connect my laptop to my office screen is highly inconvenient.Is this a bug or expected behaviour that I have to live with?

The 'Multiple Screens' tool, aka grandr, is very handy for setting up my dual monitors. But restarting my system restores the monitor setup to the (crummy) default settings. Is there a way to save these settings and make sure they are always applied when the OS boots? Putting these settings in my xorg.conf would be fine, but I'm not sure where or in what form the settings generated by grandr might be located, or if they're at all xorg.conf compatible.

I have a problem with a PHP/Apache program.
The website creates a RPG character through a traditional Wizard. It calls itself with a hidden variable being the page number and tests which page and returns the page data with the page incremented.
Each page should be treated as a seperate page and so would be unique. I am echoing the contents of POST to the top of the page and so I can see variables being returned. When I get data from an Ajax query from page three it saves the data (23 post fields of no more than 25 characters for each field). Page four does the same but with less fields - but it is NOT returning the data - only four fields being those that were originally posted.
I cut/paste the function from section three to section four and changed the displayed text and the names of variables to test so there are no code errors, since page three works and is saved to a database.
So the only option is that there is a PHP or Apache2 issue when POST variables are returned? I am completely out of ideas as to why this would even be an issue or how it could possibly appear.
Is the number of variables an issue? This page is less than the previous page.... And the form is POSTed...
PS: I am getting NOTICE errors from PHP being the POSTed variables that are not displayed/returned... I used:
error_reporting (E_ALL ^ E_NOTICE);
to stop these form being reported but do I need to test each one? PPS: Using If Isset($_POST['xxx']) does NOT allow that variable through...
PS: I have the default Ubuntu 10.04 Apache2 with all the ubuntu 10.04 updates...

I'm using RHEL 5 with the Enhanced Security. Using the suggest NISPOM Red Hat documented settings (located on the system; copy - paste) I have managed to audit failed file open accesses however, this setting only retained if I enter it at the command line (/sbin/auditctl -a ). If I reboot the system or restart the service all my -a (not -w) located in the /etc/audit/audit.rules are not retained.

Just attempted to upgrade from 10.04 to 10.10, after having updated everything. Upon completion of the upgrade I was asked to restart, however, when I restarted the PC I was presented with the following:
GNU GRUB version 1.98+20100804-5ubuntu3
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.

I have been running Ubuntu 9.10 for a while now. Today, I ran updates on my computer and also requested the upgrade to 10.04. Unfortunately, a few hours into it my computer hung. I had no choice but to reboot. When I did so the computer started a 10.04 screen and then went to a 'command line' for me to login. I am able to login, however, all i have is the 'command line'. What can i do now? Can I restart the upgrade from the 'command line'?

i am an ubuntu nooby, out of curiosity i installed ubuntu 11.04 alpha3 last night. Yes, i will definitely never install an alpha version unless i wish to test it! Frankly said, i first installed 386 version on a notebook which runs just fine. So I thought why not install the 64 bit version on my pc.
Unfortunately, the system did not finish the first reboot in order to complete the installation. First it always stopped at "checking battery state". There, I read that this bug is already fixed: [URL]... I came across this thread: [URL]... So I pressed Alt +F2 in order to log in and performed sudo apt-get update followed by sudo apt-get upgrade. Everytime there was a new update I hoped, that this will fix the issue. But when I shutdown the system with sudo shutdown now -h and restart again there is no progress.The only thing that changed is that the system no stops at "Stopping userspace bootsplash", whatever that means?
