LDAP: What it is?

I just configure my first LDAP server installation on Linux machine. A Directory service running on port no 389, that can be used for Authentication, Directory listing of person and Organization resources like computer, printer etc. is known as LDAP (Lightweight Directory Access Protocal). Don't know whats light in it :o). I used OpenLdap server to configure my service, So far able to add Linux based user to LDap server and can access the data from LAN machine through command line. Will start more work on it ... seems a good application all together. Sumit Gupta

Making Mail Server

I have been trying establishing local mail server, so far so ..boring. Its 3 days I have been doing this, First I thought Exim fulfill all my requirements, I never heard of any other software other than MTAs for this requirement. I thought Exim alone is enough for making Mail server, but I was wrong, Exim fulfill one of the requirement for mail server. and it is only a MTA (Mail transfer Agent) that transfer emails from one server to other, But it doesn't implement POP3 and IMAP which is required for a Mail client to recieve emails from your Mailbox on to your windows or linux desktop machine. But good point is that I easily found other required software for the purpose like courier which I am also installing on my Mail server. Hope fully I will get it complete today itself, Getting lots of error, but good point is still going ahead -Sumit Gupta

Cpanel using Exim as MTA

Hi, after searching for my reply for a day atlast I am confirmed that Cpanel use only exim, Its simple that I can ask them , but believe me I have a post in their forum that doesn't have reply until one day past :( And now I am able to install exim on my PC. A Bit different from other softwares that I install on linux box from source. Actually I miss "configure" file for it... But at the end I read its README and all is done as a piece of cake So In future , do read README or INSTALL or such files before doing something new. Best of luck all Sumit Gupta

Linux Problems

Hi, I have been trying sendmail and Exim for whole day. Looking what exactly they are and how to use them. But still stuck on what they are. I found Sendmail and Exim both are MTA (Mail Transfer agent), but still my Cpanel installation shows that I have sendmail and exim install on same server, How can this be? If I have sendmail listening on Port 25 than where exim is listening for email? Anyone any idea please post comment so that I can work on my project. thanks everyone Sumit Gupta

When government meets God

I was reading about SSL. what they are? why are they used? etc. I found one article at http://www.tldp.org/HOWTO/SSL-Certificates-HOWTO/x64.html. there I found a place where our local government meets the GOD in one of his normal task .... (relatively secure, nothing is certain except death and taxes) ... Its funny, Sumit Gupta

Visual Basic Express 2005

Install on my pc yesterday, and get its first look today... just few hours ago. What can I say about it. Simply amazing software. When I first look at Visual Studio 2002/2003 I thought what extra in a interface they can make. But with Express interface we have new Icons, and programming in no more just a Text editor... I thas cooool icons and things. Try Debugging in VB Express and you really find the difference. Okay enough talk on Interface, now let me tell you one cool feature I like most... Code Editing during Debugging.. in Days upto VS 2003 one has to break the Code execution and than make a text change and than run it again if you found one spelling correction while debugging. But now, just go to editor window edit the spelling and press F8 as usual :o) One more feature I observe.. while debugging I often try to make Xpath queries in Watch window, and there no "."(Dot) works but now it is. Hmmmm.. Microsoft is making us more lazy. Yet to discover its features IF you have any let me know so that I Code rather than discovering Sumit Gupta

Perl Package

Have you ever heard of Classes. OR You must have heard of packages.. I have wrote few perl scripts for my on going Project. I use procedural programming logic and perform the action I want my perl script to do. It goes all good. But one day I got a project analysis task, It's about Bugzilla a Bug Tracking software. I gone through its code and found a new concept. Making Packages in Perl. Now I got a Idea to implement my OOPs concept in perl. And I restart coding my perl scripts. Now the result of my last 3 days of recode .. I reduce 40% of code Though one thing concern me a lot if a programmer been paid for line of code he writes I get 40% less salary Sumit Gupta
