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
View 1 RepliesIf I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got

Ignoring unknown interface eth0=eth0.
ifconfig tells me

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
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?

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?
With the 5.3 CDS I started an install got through to 98% of CD 3 but I was called away. Came back this morning and the box was on, but had frozen. Every time I reboot, cold boot, I come up with black screen. Vers 0.97 <grub> Minimal BASH-like line editing is supported. TAB etc. Is there a way I can get to CD 4 and continue the install, or am I back to the top again?

View 4 Replies View RelatedJust 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 a issue that could get me fired, so I would appreciate your input. My knowledge about linux is limited
The company I work for has a Dell Poweredge 6850 that keeps pretty much everything (databases, websites, etc). The server had a Virtual Drive created from 2 Physical Drives. Since the HDD space was getting low, we got a new drive, inserted it, formatted and rebooted the system. But the system now refuses to start, giving an FAILED message, something related to EXT2 partition that cannot be read at /dev/hda1
Im new to this Cent OS as well as Unix based Operating Systems. Please help me with the below requirement.My Company is a Serach based data collector from different websites like Google, Yahoo & many more..Collecting the data from the search engines is a issue for right now.. As many search engines are blocking us to search and retrive the date after some time.. Taking Google as example : Google Blocks my IP after every 30 mins of retriving.. Application is a Windows based & using Windows 2003 as the Server.. Would like to give a Dynamic IP to the Windows Server via 1st Ethernet Card & enable the 2nd Ethernet for the Internet..Eg : eth 0 = 192.168.1.1eth 1 = x.x.x.x (Public IP)I have check with few of my friends who told me to get Linux or Cent OS installed to do a interface disable after given time & enable a secondary device or virtual interface the next couple of seconds... Like eg : eth 1 = x.x.x.1 eth 2 = x.x.x.2 eth 3 = x.x.x.3 so on.. Would like the eth 1 to be down after 60 mins & eth 2 o be up & again after 60 mins of up time eth 2 down & eth 3 up.

View 3 Replies View RelatedI 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'm running CentOS 5.3 64bit and from the get go I've had problems with the Apache server.More specifically, on what seems to be a random occurance, the apache server stops to respond.The process is still running, but nothing happens with it, and it is not responding.The /var/logs/httpd/error_log is blank for the occurance and only shows an entry after I give it a restart.So I'm a bit confused about what is going on.With that said, I need to make sure the httpd is working one way or another.I don't want to force a restart service every 10 minutes as this seems a bit too much.However, I do want to have the following:
run a crond every minute to do:If it fails, then do service httpd restart (and log the failure and restart to a file and email me a message).Any pointers on how to do that?It ain't the pretty solution, but it will save me from a very angry user until I'll figure what is the real cause for this failure.
Using the EPEL Repository, I went in and installed Cobbler to my DHCP/Gateway box.Everything went smoothly on the installation front. I went ahead and modified the cobbler settings file (/etc/cobbler/settings) to point to my server IP (same box), and then got tftp running properly. Now here's the problem.Normally, you need to run `cobbler check` to find issues and correct them. I run that, and all I get is blank. Nothing. It just hangs at the prompt until I kill it using CTRL+C.When I CTRL+C from the hanging, it states "cobblerd does not appear to be running/accessible"...
Code:
[root@PalaceRedirect ~]# service cobblerd status

Problem : centos 5.3 hangs while remotely copying data onto this server.
I have A centos 5.3 x86 Version installed on Xeon Quad core , running on 8 GB DDR2 RAM, RAID 1 confgured on SATA drives. this was old installation copy and It has many more things running on it.Therfore, I can't just reinstall it.
I have setup SAMBA PDC + ldap on it. I encounter that system hangs when I copy data into this server from LAN computers.
My troubleshooting steps :
1. I have checked for network issue , My network works fine when I transfer data between other LAN compuers.
2. Even I have tried confguring seprate LAN....
3. I thought their might be some problem with my SAMBA configuration, therefore I did data transfer from sftp .

View 3 Replies View RelatedI'm running VNC Server on CentOS5 on a brand new installation, this is for some of my students to use specific software via VNC on their machines from home that they otherwise don't have access to on their Windows machines. This has been working fine on our previous server for a few years but the hardware is now outdated so I have upgraded and put a fresh install of CentOS 5 on. This works fine for about 24 hours and then eventually one of the session ends up freezing where the user then can see everything on their session, the cursor can move but they cant click a single thing.
View 1 Replies View RelatedI have managed to configure a wireles PCI card on CentOS 5.3 and it seems to work fine. It is a off brand (Hercules) with a Ralink RT61 chipset. I installed the most current driver (RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661) from the rt2x00 Open Source Project. I now have a question that might be very simple for one or more of you to answer. When I issue the command "shutdown -h now", the machine starts to come down and brings down eth0 cleanly, but when it attempts to bring down wlan0, the machine hangs and never brings down the interface OR powers off the box. The only way to complete the power off is to "hard" power off the machine.
View 7 Replies View RelatedI just recently purchased a DELL PowerEdge 2850 and have tried installing CentOS 5.4 on it. After the install completes and it does a first boot I get the following error on the DELL console: PROC 1ERROR, PROC 2ERROR E07F0. The monitor remains black and the system hangs. Just out of curiosity I installed Fedora 11 on it to see if it was a hardware problem. Fedora installed and booted no problem. I rebooted with Fedora installed several times and left it running for 24 hours. Everything is working great. Is there something I am missing in the CentOS 5.4 install?

I am attempting to upgrade a system from 4.7 to 5.2 using a (now) DVD drive attached to the onboard IDE. Originally I had tried using a remote NFS image and a USB stick but I thought maybe there was a problem with the image. I can get up to the point of the installation of selecting the keyboard for the system and then it freezes and never goes any further. It doesn't appear to be a kernel panic since I can still switch between consoles.
I've got an MSI K9NGM2-FID with 14 drives in it. It serves as a file server for our backup server. It's got a secondary 4 port Silicon Image SII 3114 SATA card using the sata_sil module, and an old IDE Promise FastTrak TX2000. Technically I could have 16 drives but the 750W PS is walking the fine line on tripping it's self-breaker with the 14 drives and 7 fans. I would like to NOT have to disconnect all of this to do the upgrade.
I thought maybe that running the install using the "noprobe" option would help so it didn't detect and load the modules for the Silicon Image or the Promise cards and detect all of the drives but it still gets stuck on the step after selecting the keyboard. The installation info console and the dmesg console don't really provide any useful information. The installation console says:
INFO : moving (1) to step welcome
INFO : moving (1) to step language
INFO : moving (1) to step keyboard
INFO : moving (1) to step findrootparts
And the last lines of the dmesg console says:
<6>device-mapper: multipath: version 1.0.5 loaded
<6>device-mapper: multipath round-robin: version 1.0.0 loaded
<6>device-mapper: multipath emc: version 0.0.3 loaded
Is there a hidden "debug" option that will turn on a lot of extra logging?
I have just been told that httpd was not running on my Centos virtual server. It seems that my hosting company rebooted my server 2 days ago and that httpd restart failed due to:
Starting httpd: httpd:
Syntax error on line 213 of /etc/httpd/conf/httpd.conf:
Syntax error on line 2 of /etc/httpd/conf.d/proxy_ajp.conf:
Cannot load /etc/httpd/modules/mod_proxy_ajp.so into server: /etc/httpd/modules/mod_proxy_ajp.so: undefined symbol: proxy_module
I had worked around and forgotten about this some time ago. The problem arose because the most recent httpd update installed proxy_ajp.conf into /etc/httpd/conf.d which was then loaded on restart The trouble is I do not use mod_proxy (I think just to try and get a lean and mean web server) and proxy_ajp.conf does not check if mod_proxy is loaded before it tries to LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
Hence httpd fails to restart. RedHats's bug tracker lists this as an old issue (which was never resolved) [URL] My workaround was to rename proxy_ajp.conf to proxy_ajp.conf.orig so that httpd would start up correctly. However any updates simply reinstall proxy_ajp.conf and so IMO the problem needs to be resolved at source. how to ensure that httpd updates do not bite me in the future? Do I really have to run mod_proxy whether or not I need it?
I have a small problem on my Compaq Evo Centos 5.4 web server. The web server runs just fine, the problem is it fails to restart from a power outage. Simple edit the BIOS. No! For a reason I can't think of the keyboard stops working after a few key strokes following the F10 to enter BIOS setup. Then its a power cycle. If left to BOOT the PC and keyboard are fine. After hearing about viruses which get to the BIOS I will ask can NIX get that far so I can adjust the Power ON?

I'm using ProFTPd as my FTP server on a CentOS 5 box. Since updating to version 1.3.3c, I seem to have very specific problems. Connections work quite fine with about any FTP client out there, including the basic ftp command from the Linux prompt. However, when trying to connect to that server with LFTP, things go wrong. When connecting, all I get is [Connecting] then [Logging in...] and then nothing. I have to add that SSL is forced off in lftp.conf (I read it could be the problem). I sometimes get a counter for reconnection, but it never works.
The command I use in lftp is : open -u <user>,<pass> <server_ip>, the ls for lftp to establish the connection. I don't see anything at all in the server's log. I just see "FTP session opened" and "FTP session closed" in /var/log/messages" and nothing in /var/log/secure. I can give you a strace if needed. Please keep in mind that the server WORKS with anything but LFTP and NCFTP (which I also tried).

I am ClearCase Admin, new to Linux administration and our development environment is in linux servers. I have found that our development server which is RHEL 3 (also ClearCase client) hangs when user gives find command.After some time of execution of the find command the server hangs. We have to hard-boot the server.Is this the normal behaviour of the Servers? This server which I am talking about is highly used.Sometimes 120 or more terminals will be opened and few compilation will be happening in the server. And same single user some times opens multiple terminals and works simulataneously.We have been monitoring the server and found out that during the workdays CPU usage % goes very high.
