First install epel repository #yum install epel-release Install shellinabox by below command #yum install shellinabox The shellinabox config file is located in /etc/default/shellinabox file by default in Debian/Ubuntu systems. In RHEL/CentOS/Fedora, the default location of config file is /etc/sysconfig/shellinaboxd. To change web terminal color scheme to white on black follow the following steps #vim /etc/sysconfig/shellinaboxd comment below line OPTS="--disable-ssl-menu -s /:LOGIN" uncomment below line OPTS="--user-css Normal:+black-on-white.css,Reverse:-white-on-black.css --disable-ssl-menu -s /:LOGIN" This enables right change in profile on right click on browser. restart the service note* sometimes the white-on-black.css is not installed. then service will not restart/start and will give error workaround : cd /usr/share/shellinabox/ #cp black-on-white.css white-on-black.css #sed -i s/ffffff/111111/g white-on-black.css #sed -i s/000000/ffffff/g white-on-black.css #sed -i s/111111/000000/g white-on-black.css now restart the service.
