Re: How to identify a Unix machine....

Hi there,

The standard FTP service (if enabled) is also a good way to know the
system type...

[narain@dracula narain]$ ftp matrix               
Connected to matrix.    
220 matrix.in.tatainfotech.com FTP server (Version wu-2.4.2-academ
[BETA-18](1) Mon Aug 3 19:17:20 EDT 1998) ready.
Name (matrix:narain):
331 Password required for narain.
Password: 
530 Login incorrect.
Login failed. 
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> syst   
215 UNIX Type: L8
ftp>           ^^

As can be seen from the above transcript, we even don't need to have a
login on the machine to access this info. Winduz returns something
different for the same sequence of commands... I think the L8 above
signifies something special (like the OS type or something)...

On a SUN machine, I got the following...

ftp> syst
215 UNIX Type: L8 Version: SUNOS 

On a SVR4 system,

ftp> syst
215 UNIX Type: L8 System V/PENTIUM Release 4.0, Version 2.

On a Unixware (SVR5) system,

ftp> syst
215 UNIX Type: L8 SCO UnixWare System V/i386 Release 5, Version 7.1.1.

But overall, a good indication of the OS...

HTH,
Narain.

Hi
 As in telnet you can use socket programming in Win32.
connect to the remote machine and then read out the
message. it will pop out the version of Unix(variant).
There might be many other ways also.
