service --status-all hangs CentOS-4.6?
by James B. Byrne 21 May '08

21 May '08

Is there a problem with running # service --status-all as root over ssh? A system that I performed this command upon has become non-responsive on all ports, leading me to conclude that it is either hung or the cpu is completely consumed with some task.

Re:Can't get past the splash screen
by Eon Strife 21 May '08

21 May '08

Hi, Thanks for the reply. I already checked the the current user logged in the freenx by using "nxserver --list", it's only the root (the one I currently using). And yeah, I'm stuck in this screen : http://img.photobucket.com/albums/v708/EonStrife/stuck.jpg I wonder, just say if we don't use the remote desktop, but we access or use the computer directly/physically as usual, what do we do if we're stuck on that screen ? About the log of the nomachine, I think the most interesting part is the bottomost part. Note, there are many occurences of "NXFileMonitor::readData", and some 'stop' and 'destructor' words in the end, even though the nomachine is still running. === [Wed 21.

So, to use the desktop(Gnome) of the frontend I use the freenx + nomachine following the guide in http://www.centos.org/modules/newbb/viewtopic.php?forum=20&topic_id=1640&vi…. It worked. Then, I intended to add user, but I couldn't create the home folder in /home/ for the new user. After browsing, I found that somebody mentioned it's because of the automounter/autofs. So, I played around, enabled and disabled the autofs, and yes, I could create the home folder for the new user. The problem is that, when I tried to log-in to the front end using nomachine (using root) again, I could only get as far as the splash screen of the CentOS. I tried to connect using the putty (terminal), and I could interact (issuing command to the terminal), but I couldn't use the Gnome anymore. So, why in the nomachine I could not pass the splash > screen anymore ? Any solution ? Thanks. Although I can not answer your question directly, did you see anything logged on the system that you are connecting to via the nomachine client? Also, the Nomachine client provides some logging of its own as well. You may want to check for any error or permissions related information in the client's directory. That may point you in the right direction.

Maybe you need to specify the uid and gid for rsyncd on the server. If it's defaulting to nobody, that could be your problem. uid The "uid" option specifies the user name or user ID that file transfers to and from that module should take place as when the daemon was run as root. In combination with the "gid" option this determines what file permissions are available. The default is uid -2, which is normally the user "nobody". gid The "gid" option specifies the group name or group ID that file transfers to and from that module should take place as when the daemon was run as root. This complements the "uid" option. The default is gid -2, which is normally the group "nobody". For one machine that I'm backing up via rsync, my /etc/rsyncd.conf looks like this: [backup] path = /backupdir hosts allow = xx.xx.xx.xx auth users = alloweduser secrets file = /etc/rsyncd.secrets uid = 0 gid = 0 -- Bowie

IMAPS error with Dovecot?
by Benjamin Smith 20 May '08

20 May '08

I'm using Dovecot to support IMAPS on CentOS4 on port 993. Stock RPMS, absolutely nothing special done or even anything compiled on the system. About as usual as usual usually gets. But, using KMail on my Fedora Linux laptop, I keep getting the following message: (in part) "This means that although the resource, Changing the flags of message imaps://me@myserver.com:993/INBOX/;UID=0,0,1866921748,1866921754,1866921769,1866921777:1866921783,1866921795,1866921800,1866921824:1866921828,1866921834 failed., was able to be opened, an error occurred while writing to the resource.

It happens whever I mark a message as "read" and then resynch up with imap. I can *delete* messages just fine, I just can't change the flags on a message. I've scanned thru the /var/log/maillog, /var/log/secure, /var/log/messages and found nothing out of the ordinary. I've checked the permissions of the /var/spool/mail/myaccount and /home/myaccount/Mail folders - both are fine. I have another, almost identically configured mail server that is not having the same issue. I've tried refreshing my cache, and rebuilding indexes in my email program. I'm stumped. Any idea where to go next for this? -Ben -- -- Only those who reach toward a goal are likely to achieve it. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I need some NFS explanations, please.
by Steve Campbell 20 May '08

20 May '08

I have a problem with NFS that I can't start to resolve. All servers are CentOS 5 servers. One server exports a directory and two others mount it. Simple so far. A file is created on the server, and the two nfs clients do an "ls -al" and get a common (meaning the same) result as the server. Over the course of a day, and after the file on the server has been modified on the server, the results of the "ls -al" show the original common result on the two clients, and an obviously different result on the server. So I figure it's some kind of caching problem. But I figure it's a server caching problem. I next go to one of the clients and "cat" the file, and then do another "ls -al". Now the server and this client agree on the file attributes, but not on the second client which shows the original wrong result still. So now I think it's a client caching problem. Can anyone explain the above situation and perhaps some settings that will resolve this without requiring the nfs client to open the file in some way before it gets the proper file attributes? "nfsstat -m" of the client returns the following: Flags: rw,vers=3,rsize=32768,wsize=32768,acregmax=3,acdirmin=3,acdirmax=3,hard, intr,proto=tcp,timeo=600,retrans=2,sec=sys,addr=10.0.12.152 Thanks for any help.

OT: Building NFS server with LVM and snapshots enabled
by carlopmart 20 May '08

20 May '08

Hi all, I need to build a NFS CentOS 5.1 based server with LVM and snaphosts for disaster recovering to serve storage to three ESX servers for a development dept. I have 500 GB for storage. Data that I need to store on this server is 150 GB and can grow to 210 GB to the end of year ... My questions are: - Is it possible to do some type of scripting to do data snapshots every day and then copy to a remote server?? Some example, please?? - How can I restore snapshot data on the production server if I need to recover it?? Openfiler or FreeNAS isn't an option to do this task (customer requeriment). -- CL Martinez carlopmart {at} gmail {d0t} com
