CentOS 5 Server :: Updates Have Frozen Gnome Interface
Jun 21, 2010
Just setup 5.5 as Server-GUI installation last night. Ran latest updates today; it requested a restart; logged in to console; GUI desktop all looked normal at first, except that the panels on top and bottom are empty, except for the menu "Applications Places System" items (upper left) are there, but non-functional. The desktop icons for "Computer, Home, Trash" are functional. Update as I am writing this: The menu header items are now GONE as well, but icons still work (but don't help me).
Problem is, I don't have access to any apps that will allow me to reboot the machine with access to "Shutdown/Restart". If I hit the reset button, will it be OK? Or will it blow up like a Windows machine? Luckily I can reinstall if necessary, but the update thing might crash me again. All was fine before applying updates. Anybody having problems with the latest updates?
I have followed the official instructions here to setup VNC service initially and was able to get it working.
However, during the course of setting up my BIND service, I have done the following: 1) Turned on SELinux 2) Used system-config-security to add the ports TCP:53 and UDP:53
When I tried to save the settings from 2) above, my GNOME desktop delivered via VNC got frozen.
Now when I tried to restart vncserver with "service vncserver restart", I see the following. I am also unable to connect via [url] anymore.
On my other PC I was installing updates. It's just frozen up for some reason (assume screen saver kicked and did something) What should I do to minimize any file damage? Pressing the power button may be my only option? And if I do shut it down do I just run updates again to pick up where I've left off. I'm a bit concerned I'll end up with corrupted files
I've started facing the weirdest problem. I have to restart the ethernet interface a couple of times a day and everytime i do that the server locks up completely and i have to hard reboot it.info: recently shifted to a new server, all new components and new installation, OS version CentOS 5.6
At my work, we have several clients (outside clients) that have an FTP login to our FTP Server. Their login then leads them to their home FTP folder. The FTP server is currently a Win2003 box. Because we have so many clients, we would like to implement some form of WebGui that would allow each client to manage their own FTP home folder and user info, such as resetting their password if they lost it.
Is there anything like this available in linux that would provide us with that kind of control/usability?
My gnome menu bars suddenly froze for no reason. On the top, the system menu is open, but I can't click on anything. I tried Alt+F2, but I can't type anything in the popup or even close out of it. The bottom bar is also frozen, so I can't even switch between programs. The only thing that is working is nautilus, which I used to open Chrome. So without being able to run an application and since I don't know how to open a terminal with nautilus.
I took the hard drive from my server and put it into another machine to install centos with, as the server does not have a working CD drive. So now the situation is that x refuses to start when centos boots. I get a message saying: Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?
Anyone have any idea as to what would cause the time in the gnome panel to stop? This is an epic failure... I would have been late to work today if it weren't for the coffee pot. I've had so many issues with gnome's panels I'm considering switching Desktop environments.
I can install VMware Server 2.0.1 on CentOS 5.3 (32-bit and 64-bit) perfectly. However, I can't access Server's web interface by going to port 8222 on the machine's IP address. When CentOS 5.3 (32 or 64-bit) is loading, I am greeted with this message "VM communication interface socket family: vsock: no version for "VMCIDatagram_Send" found: kernel tainted." I assume this is the reason why I can't access my Server through a web browser. How do I correct this? Is there a package I need to install on CentOS prior to installation of Server 2.0.1?
It's strange, because I can install 2.0.1 on Ubuntu Server 8.10 with absolutely no problem and access its web interface. So I think this might be a CentOS-specific issue I've uncovered.
I have installation of Xen and Centos 5 (all RPMs are from Centos repositories). I have several DomU virtual machines running on this machine. When I try to copy some bigger amount of data from another physical computer to Dom0/DomU on this machine, the network freezes. The link is still up, I can see that the connection really links on the switch, but nothing is received or sent to the network. I tried to stop all the DomUs, stop the network, unload the network drivers from memory and loading them again and starting the network, but the problem persists. Only reboot solves the problem. Sometimes the amount of data have to be around gigabytes (last time it was 10GB), sometimes 500MB is enough to stop the network... I also tried to change the NIC, but the behavior is the same. Btw. logs don't say anything :-/
PS: this is the output of my lspci:
00:00.0 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge 00:00.1 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge 00:00.2 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge 00:00.3 Host bridge: VIA Technologies, Inc. K8T800Pro Host Bridge
I used my boot disk in rescue mode to solve this, but I would really like to know how to do this the easy way.
Question: when I am booting up and getting all those "OK" green remarks, how do I cancel a daemon that freezes instead of giving me an ok or failed? I have tried <Ctrl><C> with no joy. I have tried dropping to interactive mode ("I") and bypassing the bad daemon, but interactive mode freezes when I go to start GDM, so no joy there either.
I'm running CentOS 5.4 and noticed that for the past month there haven't been any new updates showing up either on 'yum check-update' or 'yum update' (I'm interested in basic and security updates). Although this may be right, I wonder if there is an online reference where I can check the updates that are released for CentOS (security bulletins) and make sure if there is anything wrong with my update system.
I'm having a problem with connecting over ssh to a server (wrdsvr) that has me perplexed. I'm using putty to connect from my WIndows VM desktop to a SLES 9 server. If I connect to wrdsvr from my desktop over ssh and run certain commands with multi-line output, the display freezes after the first line. If I connect from my desktop to a different server (oksvr), and then from oksvr I connect to wrdsvr, then there is no problem. In fact, by running 'w' after connecting in that roundabout way I can see that subsequent commands I type into the frozen window still run.
I just can't see anything in the window itself as the display is frozen. I have sshd logging running in debug mode on wrdsvr and there is nothing produced during this. There is also nothing in the putty event log. If I type 'exit' in the frozen window, the server sees the connection as closing normally and then gone. Usually my putty window would then close automatically, but in this frozen case it doesn't. So although it is sending characters I type in, it doesn't seem to be receiving the output in return.
commands that run successfully are: w ls man less
commands that cause the display to freeze are: ps ax ls -l top (for this one I don't even get the first line of output, it freezes immediately)
The machine I'm connecting from is a VMFusion guest running Windows XP. I get this behavior connecting using putty, but I also installed a demo version of securecrt (when this issue occurred previously) which saw the same problem, but I can't repeat it as my license expired. (Last time the issue went away while I was troubleshooting an immediate service-affecting problem on that and a number of other servers and I don't know what fixed it!) I exported the putty registry keys and the profiles for the two servers are identical. I tried loading the profile for oksvr and temporarily changing the hostname to wrdsvr, but saw the same issue. I am connecting over a Cisco VPN.
My colleague is on the local network and does not see this issue when he connects to wrdsvr using putty. We are both using the same version of putty 0.60. Here is the background on the servers. Both wrdsvr and oksvr are running SLES 9. My actions just before I noticed these issues were the following. I updated them using you (yast online update) to the latest patch versions. Using the rpms from Novell, I installed binutils, make, gcc, and glibc-devel and finally VMware tools on both. I then rebooted. Since then I've run you again but that hasn't changed anything. I've compare the installed patches using diff and they are the same. Now I'm working my way through the output of rpm -qVa on each one, but nothing so far.
I have a remote CentOS server (5.4 Final) to which I need to add remote access to a GUI front end. I have SSH access to this box (no physical access, I rent it and it is housed in a DC) and I think I have managed to install Gnome correctly:
ok I am using a customized CentOS distro that is looking for 3 network cards on boot. eth0, eth1, eth2. I do not need eth0 and need to bridge it to eth1.
Sorry if this is in the wrong group but its a bit of an odd one but I think comes under Server Support.. I've set up both x11vnc and freenx in an attempt to eliminate either as a cause for this issue. The problem is that when I log in with either, I can get into the desktop and run things from the menus but when I make the System menu active - the session hangs and you have to killall for the freenx or vnc processes.
I was wondering if anyone might be able to help me investigate this and hopefully fix it as I'm not sure where to look given that both types of remote connection seem to have the same issue.
I've created a brand new CentOS 5.4 (Final) 64bit machine AMI on Amazon EC2. This was based off an existing image. I was able to follow the wiki to add NX server. I am using WIN XP desktop for NX client.
I can connect to the EC2 machine and get the GNOME desktop fine. I see the usual CentOS desktop and poke around.
Q/Problem:
I expected to open the Terminal window and get a shell prompt to su into root user (I need to be root to install some software that needs GUI). I do not want to install this from my plain SSH connection to EC2 (hence the NX server etc.).
When I open the Terminal window, all I get is the NX>105 prompt. I need to get to a shell prompt so I can su into root. For life of me, I cannot get around this prompt (I looked at NX documentation too). Note that this is a prompt NOT on client but on the remote machine. I do not need this as I'm already authenticated and logged in to remote GNOME desktop.
Obviously the TERMINAL is running some NX start up script (I've no idea which one). If there is some other way to sudo into root?
In general CentOS search automatically after startup for available software updates.Then after some (~20-30) minutes an icon appears in the toolbar which the user can click and install the updates.How can I manually speed up/trigger IMMEDIATELY the search for updates (without waiting for the built-in search)?
right now i have fallback mode on its forced me to fallback mode, what i don't get is on the betas of F15 beta worked just fine and now i just goes right to fall back mode. actually its ok i like it the way it is but is there is list of supported video cards and what not?
I just installed Arch Linux with Gnome and gdm is set to boot into gnome as soon as it boots. But I realized that the barebone gnome package that I installed doesn't include a terminal or a text editor so I can't install anything further or modify the rc.conf file to make it boot without gdm.
Is there a way for me to kill x from the Gnome interface?
I have recently upgraded to 11.04 and am running the Classic interface as I don't like Unity.However, I have noticed so far two areas where this Classic version has gone backwards from the default Gnome in 10.10 and earlier.I can't rearrange window buttons on the Window list, nor can I drag-and-drop say FLAC files onto the button for "Movie Player" any more -they end up pinned on the panel!How can I get back the ability to drag window buttons around and and turn off the annoying pinning feature and get drag-and-drop back?
I just installed Ubuntu 10.10 to try out right? Well, I tried to expand the height of the bottom task bar to 35, and when I did, it had an graphical issue happen. Its almost as though the image isnt large enough so it starting repeating it to fill in the height. I think I can do screenshots so I can show below. Is there anyway to fix that?
The other question I have is, why is GNOME and KDE both using such larger buttons and drawing then Windows or even MacOS? Can they be made smaller? I can include screenshots for those if I need to.
There have been no updates recently (for almost two months) on any of my CentOS 5.5 boxes when I run 'yum check-update'. I may be misunderstanding the repo setup, but looking at the file mod dates, it seems that there hasn't been an update since 2011-01-06:[URL]...Meanwhile, a prominent North American Enterprise Linux vendor has had multiple security and bug fixes since then:[URl]...Is CentOS 5.5 still getting updated, or am I missing something (quite possible).
After doing an update a couple of days ago (had previously upgraded to 5.6), the font size in firefox (file forward reload, etc), terminal and the panel (using xfce) are significately smaller. Searching the web, mail lists and the forums have not resulted in finding anyone else with this problem. I did notice that glibc has a bug that is currently being worked on at Redhat but it is unclear if the font problem I am seeing is related. Note also, that the initial upgrade to Centos 5.6 was successful.
When I try to install the wireshark-gnome interface I get a notice about needing two dependencies. One is portaudio and the other is the jack-audio-connection-kit. Seems like kind of odd dependencies for wireshark. Do wireshark really need them? VoIP related maybe?
