Server :: If Server Failed Or Offline - Any Way To Check Status?

Mar 9, 2011

I would like to implement something when a server is offline for whatever reason. For example. I got my own DNS servers and webservers. I would like it if the users goes to and the server it is actually on is down for maint. or For whatever not able to respond. What can be done so that if the server isn't able to be contacted that it can point to either a another server or the dns somehow can display a page stating who to contact to report a problem or to let them know its down for maint. And can goto a site to check the status or whatever.

Server :: PHP And Sendmail With External Mail Server / Failed Reverse DNS Check?

Jun 7, 2010

After searching the forum I could not find a clear answer to my question so I am giving it a try...

I have installed a LAMP server with Postfix as mail server. The scripts send email as user www-data using the mail server on the same machine.

However, the email got rejected by external mail servers (failed reverse DNS check) so I setup a mail server that meets all needed requirements.

Now I would like to use this second server instead of the mail server on the LAMP server. I found that this could be done with changing sendmail settings in php.ini (I think).

However I am not sure how that will go: www-data is no actual user on the new email server (which requires authentication before sending). Do I need to create a new user on the email server or change the settings in php.ini to match an existing user?

Server :: Sendmail Server - Status - Sent - But Unable To Retrieve On User Inbox - FEDORA CORE 9

Jan 20, 2010

We're running a sendmail server on a fedora core 9 which we've configured recently. The problem is, the server is working fine but there are some e-mails that enter our server but doesn't get forwarded to the user.



Here it says "stat=Sent" but nothing from the above mail address has been received on the client's inbox. We've experienced this with Microsoft Outlook, Outlook Express and Thunderbird alike so far with Two(2) of our user accounts.

Server :: Putty/SSH Login Failed When Using RSA Public Key: 'Server Refused Our Key'

Sep 19, 2010

ENV: openssh-server-5.4p1-1.fc13.i686 Problem: I am unable to ssh using Putty (when using ssh-auth/pki) to a fedora box . I get the message: Server refused our key. Here's what I tried so far:

- Tried generating rsa (as well as dsa) keys on the linux server and put the generated public key in the ~/.ssh/authorized_keys. Then I converted the private key using PuttyGen.

- Also, tried generating keys using PuttyGen and then converted the public key and placed it on the server

- Configured the sshd server (ssh_config) for using RSAAuthentication=yes. Tried all combinations and purmutations; however, I still get the "Server refused our key" error.

Ubuntu Installation :: Upgrade 10.10 Server To 11.04 Server Failed?

Apr 30, 2011

I am running 2 Ubuntu servers, one as UEC frontend and the other as UEC node. I started, last night, the server upgrade on the frontend. As it promised to take several hours I left it alone to proceed through the night. This morning it was waiting on a prompt which, by virtue of hitting esc to relight the monitor, it continued upgrading packages. At some point subsequent to that it paused on a discrepancy between the eucalyptus.conf file the install wanted to save and the eucalyptus.conf file that existed. I reviewed the deltas and determined that the current, as it existed, would suffice. I received 3 more messages on the console:

Installing new version of config file /etc/init/eucalyptus-network.conf. Installing new version of config file /etc/init/eucalyptus-conf...
eucalyptus start/running process 15290
Then no further console messages nor apparent disk or cpu activity
I can shell into the machine and see the following:
root 7077 6784 0 Apr29 tty1 00:00:33 /usr/bin/python /tmp/update-manager-0r8nH5/natty --mode=server --frontend=DistUpgradeViewText

General :: Check Status Of A Shell Script?

Aug 2, 2010

I'm running CentOS 5.5 and have created an init script. The start of the script contains:

# Source function library.
if [ -f /etc/init.d/functions ]; then
. /etc/init.d/functions

The start bit works fine, but I'm having problems with the status and stop part:

echo -n "Status of script: "
status "/bin/sh /path/to/"

In PS AUX the command appears as "/bin/sh /path/to/" and I can see the PID. But when I run:

./my_init_script status

It says the script is not running. Should I be using the /bin/sh bit, or just the full script path, or just the script filename?

The stop part of the init script utilises "killproc". Again what command should I be using to successfully kill all occurrances of the script?
