debian 3 question

Debian 3.0 is a very very old distribution, which is out of support for a long time already. That means you wont get security updates for it anymore.

If you really want to use debian 3 here you can find the ISOs

http://mirror.debianforum.de/debian-iso-archive/woody/i386/ 

So what kind of information you want to get of the server? Some Hardware specs? Some files saved there?

Does this server serve things directly to the internet?

I want to find out what exact HW is used like HP, IBM or dell and model number.

This server sitting some where in the data center. I don't have any details so far.

How do i find what release installed on my server?

cat /etc/debian_version
3.0

I am not getting what release it is just 3.0

lshw
su: lshw: command not found

in debian 3 there are many releases. how do I find what is my release level?

please advise

how do I find what is my release level?

it would be the second decimal
since yours doesn't have one it is the initial debian 3 release
i have not been able to find a valid site with an iso for that version

To determine the hardware of the server you might boot from a bootable linux CD like knoppix to run lshw and other hardware detection and diagnostic tools.

Can i able to do in place upgrade for Debian

I have Debian 3 and want to upgrade to 4.

Can I able to upgrade from 3.0 to 3.1 and upgrade to 4?

theoretically yes, but im afraid there are no working and complete repository servers out there anymore which provide the packages for the mentioned distributions.

A few days ive tried to use the jigsaw files to create the debian 3.0 ISO images and it failed due to files missing or wrong on the servers.

So before you try a update be absolutely sure you have a working backup of the server OS and its files.

I have debian 3.0 but how do i find if it is r1,r2,r3,r4,r5,r6?

 cat /etc/issue
Debian GNU/\s 3.0 \n \l

cat /etc/debian_version
3.0

 uname -r
2.6.1

I am trying to find the exact image to download and not available.

can you able to locate the exact image location

I went to this site which one is exact match?

http://cdimage.debian.org/mirror/cdimage/archive/

cat /etc/issue
Debian GNU/\s 3.0 \n \l

cat /etc/debian_version
3.0

 uname -r
2.6.1

Unless you math package versions it is:
3.0_r0 to 3.0_r6 (Woody)

what is debian jigdo?

jigdo is a program that downloads deb files and combines them in an ISO file.
