passwd file - which language is this?

[shnsqr]

Hi guys
I am wondering which encoding language it this used to encode the username and password of the dm into single line!

I have the passwd file and want to know the user and pass of the dm without changing them.

In fact, I want to "decode" the "encoded" line in the passwd file without changing it
So I don't want to rest it to root:dreambox, I just want to know it

The easiest woukd be to reset to root/dreambox(elsewhere on this forum) and then use "passwd root", through telnet, to change it to whatever you want.

I know how to reset it, but I want to know the current password without reseting..

That is the whole point about having a security password, if it was stored in a way which would let you find out what it is, it would not be a very secure password would it O-zzz

If you need access to the box simply reflash it.
If you don't want to do this then we know why !
You will never find out that password.

The encoded line is generated by a non-reversible encryption of the password the original user has input (the time he installed the system or last used the 'passwd' command).

Every subsequent time you log on to a linux-system, the password you enter is encrypted the same way, and then result gets compared against /etc/passwd.

To cut the story short: you simply can't decode passwords off /etc/passwd, it's mathematically proven impossible (and that's the way it should be - this is about security, as has been already stated here). You want to hack someone's account without them noticing it - find another way...

thank u all guys
it seems impossible to do that

Unfortunately its not impossible.

Its possible by exploiting the very process you mention....

Every subsequent time you log on to a linux-system, the password you enter is encrypted the same way, and then result gets compared against /etc/passwd.

Granted, it could take a VERY long time to crack a strong password, but a weak one could be cracked in no time.

For those who are tempted to use weak passwords, its advisable to use as many characters as you can possibly remember along with a mixture of upper/lower case letters, numbers and special characters. Dont use common words that can be easily read from a dictionary.

@shnsqr: This is a satellite hobbiest forum, not a cracking/security based forum. If you really want to do whatever it is you are attempting to do, you'll have to do the leg work yourself, which will mean a lot of work for you.

My advice: Ditch the pay server and take ownership of your box.
