We've installed RHEL 4 (Linux Redhat) on a virtuel machine VMware. This virtuell machine has 2 CPUs (CPU0 and CPU1). We also installed the JBoss on it. But we notice, that in run time the system load of one CPU is quite often 100%. I am not sure if this is caused by the application running on Jboss or there is error by configuration on Linux.

Looking for my process monitor you see that I didn't run any program but my CPU01 100% overload and fax worked a lot,CPU02 just a bit.Ram's just 12%. So what I when wrong? I install Ubuntu 10.04 x64 - ram 4Gb - Nvidia quadro 140M.

I have servers where the disk is partitioned into OS and application partitions. The application is rather sloppy with its file handles, and frequently when there is a system crash, its file systems get corrupted. This will cause fsck to halt the boot, requiring me to get on a remote console, enter the root password, and fsck the file systems.
Is there a way to have just the OS partitions get checked and mounted, then check the application systems, only after the OS is loaded, so I can ssh into the system, instead of having to use a bandwidth-hogging remote console?
The app partitions are already at fsck level 2 in /etc/fstab, but this doesn't prevent OS loading from halting. If I set the fsck level to 0, I don't want the application to start if the partitions are unavailable. Should I just leave the fsck level at 0? Or should have the partitions marked "noauto", then have a startup script run fsck and mount the app partitions?

I was try using some configurations but http pages not loaded.
what is happening on my Centos virtual server (ps I'm having a great time re-learning Linux after a large gap and usually try and find out myself but this has me confused) First thing I did was install Tomcat and try and change the port to 80 using iptables -nat and it complained a kernel module was missing. Instead setup Apache to redirect requests so that's now working I then tried to install CSF firewall and the validation perl script returned fatal errors so I assumed OK my virtual server Kernel is restricted and used denyhosts instead which is working great
Here's the confusion.. I later retried the csftest script and it now works including all the iptables and nat stuff that fataled before. I've not rebooted or changed anything except run denyhosts and the postgres daemon + ended a few daemons that I didn't need (eg pickup,tlsmgr,courier,postfix,qmgr,saslauthd) Running lsmod returns nothing and /proc/modules is zero bytes so I'm not able to tell what is loaded? I'm tempted to try and get Tomcat redirecting via iptables and see what happens but if it works I don't like that something seems to have changed.. before I ran it direct as root now I'm SU into root from another login
I have /var/log/audit and /var/log/audit.log owned by root and 600 permissions. I've also removed and made an empty /var/log/audit directory when that did not we work either.

I have a BIND server that I'm setting up with different views. There is another server out on the public Internet that currently handles all inquiries for this domain.

You can try to start the mysqld daemon with:

View 2 Replies View RelatedI 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?

View 1 Replies View RelatedThis is an odd question, but I can't figure out why my nagios emails aren't being sent. In fact, I got my last one three days ago so it *should* be working.
I have everything in contacts.cfg, and the admin page tells me that the following should be sent: Unknown, Warning, Critical, Recovery, Flapping, Downtime
I also have notify-service-by-email and notify-host-by-email.
I have no idea if nagios emails just don't want to be sent or what -- and I'm not even sure if the nagios emails are even trying to be sent.
Here's my contacts.cfg code...
There's nothing in /var/log/nagios besides the mention of that email address in objects.cache, so I have no idea if an email was attempted to be sent. My sendmail queue is empty as well.
Meanwhile, I have some downtime on a service and didn't get notified. Only the web interface is helping me out here. Any ideas why I am not getting email? How can I run a test to see if everything's working okay?

View 9 Replies View RelatedI have downloaded the Apache web server so I can set up a local web server to test my PHP pages. The download automatically went into the default "Downloads" folder instead of the /opt folder where the Apache instructions said to download the file to. I have tried to move the file from the Downloads folder to the /opt folder but am denied access - says I don't have enough privileges (or some such thing?). Bummer.
So I tried to use the terminal to install the file that I downloaded from Apache (following their instructions - actually copied/pasted the command line so there would be no typo problem) - no joy.
The first thing I was instructed to do was to enter the su command, which I did, and was asked for a password. I have tried every password I have ever used on this system and I receive the following:
su: Authentication failure
and it returns me to the prompt. What is my password?

Is this possible, since I do not have the server set up as my gateway? It is merely connected to the router like everything else.

I seem to having some strange issues with my new sendmail server and was hoping that somebody can offer some assistance with this issue. I recently tried to setup an enviromental monitor that sends alerts via email using a dedicated email account I created on my sendmail server. For whatever reason, it does not seem to be able to send emails, and I have verified the account credentials multiple times.
So I attempted to run a telnet SMTP test to determine what the problem was. I was able to connect and send the emails using this test perfectly fine from my local subnet, however I ran into problems attempting this test from the outside world. When I connect the SMTP PORT 25 from the outside world, I get what seems to be a malformed SMTP greeting.
