I logged into metasploitable from kali linux using SSH.(Windows host)

Now I want to access file named config.inc (/var/www/mutillidae/config.inc) in metasploitable.

I tried opening it using sudo nano /var/www/mutillidae/config.inc command and it showed me an error.

error opening terminal: xterm-256color

  • How to overcome this error?
  • Is there any problem as I opened it using SSH?
  • Try sudo less /var/www/mutillidae/config.inc and use ssh -X instead of just ssh Aug 13, 2017 at 13:33

    try sudo vi /var/www/mutillidae/config.inc

It seems like you have a problem with the terminal definition.

Try using xterm instead of xterm-256color

export TERM=xterm

or the following terminal setting:

export TERMINFO=/etc/terminfo
export TERM=linux

Also, if you still have problem with nano try using vi which is a simple editor and doesn't required much from the terminal

sudo vi /var/www/mutillidae/config.inc
  • Thanks. After changing it from xterm-256color to xterm, it worked. Aug 13, 2017 at 13:48
