I manage a number of different web sites for various clients, and this is generally what I do. First, the top priority for security updates should be the web application itself. The vast majority of attacks will be targeting your web site and the code that runs it, and this needs to be kept secure. If you use off-the-shelf web applications, this is one ...

The easiest way to solve this problem is to run CentOS or Fedora, rather than RHEL. Anything along the lines of walking the filesystem using sed is the path of madness.

OpenSSL on RHEL6 is affected only in versions openssl-1.0.1e-15 through openssl-1.0.1e-16.el6_5.4. openssl-1.0.1e-16.el6_5.7 and later contain a fix backported from OpenSSL 1.0.1g and don't bump the letter part of the serial number up. Thus, it's likely you are confused by the e and your system is in fact patched. Source: ...

The program which modified the sender was postfix. By default crontab/mail will use username as email sender without domain parts. So the sender becomes myuser Because postfix sees sender doesn't domain name, by default postfix will append hostname as its domain. See parameter append_at_myorigin and myorigin in /etc/postfix/main.cf. The sender becomes ...

Firstly, I will use FreeIPA and Red Hat Enterprise IdM interchangeably. If this causes discomfort, let me suggest a drink. FreeIPA should be a separate Kerberos realm from Active Directory, and should use a separate DNS zone corresponding to the Krb5 realm. If your AD Domain uses the DNS zone "domain.com" with child zones "dev" and "prd", you would want to ...

For a very large part it depends. The obvious is that Critical security updates are typically best installed As Soon As Possible, but only you know your infrastructure and platform. What is ASAP is specific to you. If you're running a web server, something recent like: "CESA-2014:1919 Critical CentOS 7 firefox Security Update" is not an issue for ...

As a lesson to people who try to install old versions of Linux on new hardware, this won't work... RHEL 6.2 was released in December 2011 The HP ProLiant DL380 Gen9 server was released a few weeks ago in late 2014... HP's compatibility matrix states the certified operating systems and minimum versions needed to operate on a given hardware platform. ...

Try check the existing permissions on the file: ls -l index.html Fix them if necessary: chmod 644 index.html If all the standard permissions are correct and you still get a Permission Denied error, you should check for extended-permissions. For example you can use the command setenforce 0 to turn off SELinux and check to see if the problem goes away. ...

It seems like you have nothing in /mnt/cdrom/ directory. Thats why Yum gives you the following error: No such file or directory

The OpenShift cron directories are meant to contain the actual scripts to be run, not traditional crontab-style entries. So you should instead write a simple script to call your PHP code. #!/bin/bash /opt/rh/php54/root/usr/bin/php ../../../cron/status.cron.php

I am not sure from where the crontab picks up the hostname part of the from email address, but one thing that you can do is to add a MAILFROM= line on the very top of the crontab so that it will send the email from the address mentioned in the MAILFROM= line. [root@mercury01 ~]# crontab -l MAILFROM=root@mercury.example.com */10 * * * * sh ...
