Network Interface BondingInterface Bonding is one of the simpler tasks which ensures high availability on the network. Bonding/Teaming is a way through which two or more physical NIC cards could work in tandem in order to ensure high availability from network perspective. It saves us from a network switch failure, network cable failure as well as NIC card failure. Ideal configuration for a high

Did you ever want to connect to IBM lotus sametime using the Linux messenger client (pidgin)? Here is a procedure of doing the same:-OS:- Linux redhat 4 U4 (Nahant)Messaging client:- pidgin (by default included in Redhat). If you don't have pidgin, I would recommened downloading the rpm or debian package from Internet depending upon the OS version you have. Its a nice client used to connect to

Ever wanted to get rid of some of the old veritas disk groups from a Sun Solaris box in order to allocate that space onto a new server? Here is a short summary of steps which could be really helpful. As we all have faced these scenarios, I thought of documenting it.RequirementTo remove about 10 recently allocated storage LUN devices (out of available 18 devices in the veritas disk group) from the

My experience with SUN Sparc servers has been pretty good except for the fact that Sun charges $$ for anything which does not qualify as support and hence does not fall under master support contract.I was once setting up a SPARC box V4** series and wanted to connect it to Sun Storage. I was told by Sun that it would cost us to connect the server to storage, as it was a new addition and not an

Thought of sharing this vital info and challenge which I faced while setting up Linux on Dell PowerEdge server. I am a firm admirer of HP hardware machines and there ease of deployment. The thing which I liked about Dell's motherboard was the presence of two onboard NIC cards compatible with Broadcomm redundancy module. Although not required but this could very well be a boon for NIC bonding for

At some point of our daily tasks, we come across a scenario where we would prefer to be able to send the attachments via mail command in Linux or Solaris. Here is a quick way to do that:-# uuencode abc.txt abc.txt | mail -s "subject" email.address@domain.comuuencode is a utility which is available in sharutils rpm for Linux or as a package in Solaris.This is a quick/easy way in order for sending

This is actually a continuation to my earlier post. There was an instance in which I ran into an issue with pseudo devices. Here is a shorter version of what happened:-We manage an Oracle 10g RAC cluster on two Linux boxes which have ~30 EMC devices. Out of which about ~25 devices are shared between both servers** and remaining ~5 devices are different on both servers, which means that there are

I am having a lot of servers actually connected to various EMC storages like Symmetrix, Clariion. As with all storage softwares, the biggest challenge is to manage the multi-path devices and to ensure that devices remain on OS even in case of a Service processor failure or an HBA card failure.As with all other storages like HP, SUN etc. EMC provides a software known as EMC Powerpath. This

I came across to this nice utility for accessing RDP (Remote Desktop for Windows) through Linux/Unix based systems through X windows.rdesktop is a client which is capable of communicating with Windows Terminal Services, thus bypassing the slow "mstsc" services of Windows. I prefer to connect to some of my Windows servers through a desktop Linux (run-level 5 as usual :) ).The syntax is pretty easy
