thank you all guys....

but my problem is that , I want to write a script by which the script asks to enter the host name and the community.. so that the TCP connection will be drawn on the screen as a result of this script....

future: ofcourse I can get these info you wrote me if I have the OIDs..but in my script I cant specify the OIDs because if the values are changed then I cant use the script anymore....
the result of my script should be as the result of SNMPTABLE command..but I cant use this command for some reasons..I must use the snmpgetnext to show the whole table not some info from the table...

thanx alot :-)
