[128] | 28 | DEPENDS |
---|
[126] | 29 | On Debian, you need the package |
---|
[128] | 30 | |
---|
[126] | 31 | apt-get install tmux ncurses-bin wamerican nmap |
---|
| 32 | |
---|
| 33 | wamerican (or wfrench...) is used to choose a random word in the file /usr/share/dict/words |
---|
| 34 | for each new tmux session. |
---|
| 35 | ncurses-bin is required for the tput command |
---|
| 36 | to automatically split your terminal into several small panels. |
---|
| 37 | nmap is only used for dynamic DNS domain and dynamic scan. |
---|
| 38 | This is not mandatory for general use. |
---|
| 39 | |
---|
[128] | 40 | By default, tssh use tput to know the number of columns and lines of your terminal. |
---|
| 41 | It takes 10 lines and 40 columns for each windows by default. |
---|
| 42 | If tput is not installed, the default is 16 windows... |
