I am considering attacks, actually i have proof of them and that's why i am posting here, trying to find out how they can get in other than SSH and FTP.

I do regular updates of my server so as far as i know everything is patched, should be no vulnerabilities,also,no one else has access to the server.

To brute-force my root account 506938 times they will need 253469 IP's cause they get permanently banned after 2 failed login attempts, but even if they did, my password is over 30 randomly generated characters long including upper + lower case letters, numbers, symbols and brackets.

For comparison a 10 char password with upper + lower case letters and numbers has a bit over 107 Billion combinations so i wish them good luck if they try to brute-force their way in lol.

Thats why i've posted here though to find out other ways they can get in other than SSH or FTP login so i can take measures to stop them or reduce their chances of success.

nwvolinfo

NWVOLINFO(8)							     nwvolinfo							      NWVOLINFO(8)

NAME

       nwvolinfo - Diplay info on NetWare Volumes

SYNOPSIS

       nwvolinfo [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -v volume ] [ -N ]

DESCRIPTION

       nwvolinfo displays information on a NetWare Server Volume.

       nwvolinfo  looks  up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more informa-
       tion. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server,  nwvolinfo
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.

       -v volume
	  The volume name to be used. Defaults to 'SYS'.

       -N
	  Display the information in numeric-only format for use in a pipe.
