How to set up phpMyAdmin on CentOS 6.2. It would be a good idea to set up phpMyAdmin as a secure website (HTTPS), rather than in clear-text (HTTP). This will ensure that all traffic between the web browser and phpMyAdmin is encrypted.
I will be using this CA to generate the necessary certificates, but don’t worry if you don’t have one, you can use makecert or OpenSSL to generate a self signed certificate. Read more »
January 25th, 2012 Frank Boros Anaconda is the installer tool for Red Hat Enterprise Linux and Fedora. This tutorial is applicable for their derivatives like CentOS and Scientific Linux also. This tutorial empowers you to fix the bugs or missing features in installer without waiting for Red Hat. The update image you generated is used while installing.
Anaconda update image involves updated files from anaconda itself and/or its dependents. In my case I take kudzu as dependent. BTW kudzu is a hardware detection tool. i.e., I am going to patch two files, one from anaconda package and another one from kudzu package. In your case instead of anaconda/kudzu it may be some thing else.

January 24th, 2012 Frank Boros Ubuntu and some gnome based distros use a centralized password management tool called Seahorse, which is a GUI front end to GNOME’s keyring management system. It stores all your saved passwords, PGP keys, SSH Keys etc. used in different applications with a master password. This master password is same as your initial login password.
Usually, when you login, the keyring is automatically unlocked. But when you change your login password or enable automatic login, the keyring cannot be unlocked automatically and a prompt appears, “Enter password to unlock your login keyring”. Read more »

Installing a Perl module is not a genius’ work, but getting it done without root access can be a challenging task (of course not impossible). You may face this situation when you do not have rights to standard directories where a Perl module is installed. In this tutorial we will see how we can install a Perl module without root or super user permission by installing it in separate non-standard directories.

January 22nd, 2012 Frank Boros Recently I needed to configure a solution for remote desktop on a Linux server. I decided to give XRDP a shot which uses TigerVNC Server by forwarding the standard RDP port of 3389 to a port VNC is listening on. The end result is to set up a SSH tunnel that forwards local port 3389 over SSH to XDRP which is listening only on the remote localhost on port 3389 as well. Use the information below to set this up on CentOS Linux though the instructions will be similar for other Linux distros as well.
First install XRDP via the EPEL repository. If you do not have the EPEL repo installed then you can attempt to use the command below to do so or checkthis link for an updated version of the EPEL repo RPM file for CentOS Linux.

NTP, Network Time Protocol, it is an Internet protocol used to synchronize the clocks of computers or servers to some NTP server on internet or intranet. This is just a brief howto about installing and configuring NTPD (Network Time Protocol Daemon) on a Linux server which in this case is specifically NTPD. First we will install ntpd, then update the current time on the server, configure ntpd to restart on server boot, and then start ntpd.

January 21st, 2012 Frank Boros How to port forwarding with iptables between 2 hosts on different networks in Linux?
I’ve been reading for about 2 days iptables forwarding examples and I cannot do a simple port forwarding. I got 2 machines on different networks. server1 (S1 with ip 195.21.2.41) is at my house and server2 (s2 with ip 10.234.141.126) is at Amazon EC2.
I need to forward all the traffic that goes to s2 to s1. I tried this:
Flushing all rules, activate kernel parameter to forward, add a postrouting and prerouting rule
January 21st, 2012 Frank Boros We just moved from a 32-bit machine to a 64-bit machine. We have quickly ran out of memory despite the new boxes have twice as much ram as the old boxes.
Running a simple ps command will illustrate the problem.
