NDLP Server Information - TOP -
Connection:
Use WS_FTP LE (see Tools) or CuteFTP to transfer your files to the RS6 file server.
You can utilize a Telnet program (OnNet 32 comes with TNVT Plus) to access a command-line interface to the UNIX server.
Login information:
You will need the appropriate account information to login to the UNIX servers. Usually, this is the same as your Network ID or Email ID. Also, you will need to change your default password (supplied by ITS when your account is set up).
Passwords should be >4 characters and <14. Use only alphanumeric characters and include both kinds in your password. You can include upper- and lower-cased characters. (UNIX is a case-sensitive platform, so remember if you do this).
To change password:
Use the command passwd to change your password at any time.
Logoff
To properly end your UNIX server session, type exit.
