I am SSH-ing to the box.

Well, this kind of silly but I think I am missing something. So we have this Solaris 10 server which acts as syslog server for network devices. Problem is the syslogs clutters whenever I use the...

Without even little knowledge of your network infrastructure, I don't think it's possible to just hand out the solution.

Please let us know how your clients are connecting to the server. Is there...

I'm sorry, but I found this a bit funny. How is it even possible to install a System Z RHEL on x86 platform? :D

If you really want to free up some memory space, by clearing out free page caches, directory entries and inode caches, try the below:


for i in 1 2 3; do sync; sleep 1; done; sysctl -w...

I would suggest rather than decreasing the reserved block percentage, use tune2fs -u to specify a user id (usually user id of the application which will use the file system, I'm assuming it's oracle...

You can safely turn off the NetworkManager service. It's good for a Desktop computer but not for a server.
chkconfig NetworkManager off
service NetworkManager stop

Well as pointed out, it's recommended to use the NTP servers for updating date/time using the ntpdate command.

If this is not available, then the next recommended method is to use the hwclock...

Hi,

Please post the contents of the /etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1 files.

Hi all.

May I get some expert advice on troubleshooting performance issues of a 1000 nodes Apache LB cluster. Users report slow loading/response of webpages. Different websites are hosted on this...

You have to specify ChrootDirectory in /etc/ssh/sshd_config which will be chroot-ed during an sftp session. You may make this as the home directory for the "functional ID" (shared ID I suppose).

There's the proof. It's pretty obvious that gdm user does not have any permission on /var/lib/gdm. Please change the ownership as suggested earlier:

chown gdm:gdm /var/lib/gdm

Could you post the output of the following command:

If you really have done it (accessing through virtual terminal CTRL+ALT+F1/2 etc or through ssh), then there's only way it can be solved: remove and reinstall GDM.

But, I'm sure it can be...

chown -R gdm:gdm /var/lib/gdm...

Yes, vsftpd works on the same old ftp protocol and supports both active and passive modes. But, it's really tightly secured. That's why the name "Very Secure FTP daemon" :D

True, xinetd is not that much used now a days. But it sure does a good job of make the system resources available for other use. For an example, a PXE server serving TFTP requests. Now, do you really...

Great! :b:

I understand /dev/vg_domino8/lv_domino8_base is still appearing. If so, try to figure out which dm device it corresponds to (from /dev/mapper) directory. Then, you may take a look at /sys/block/dm-x...

Have you tried deactivating the LVs and VGs which were on the affected PVs?

lvchange -an vg_name/lv_name

After that, you have to use lvremove and vgremove to remove the...
