How Termius detects the server’s OS

To detect the OS installed on a server, Termius executes a script (see below). It happens each time when the connection is being established (in the exec channel). Having found out the OS installed on a server, Termius can display the logo of the OS next to the host name in the interface, instead of a generic icon.

The information about OSes is synchronized across all devices (requires a premium account).

Only the mobile versions of Termius detect OSes. The desktop app doesn’t detect OSes, but it will display OS logos if the OSes were detected in a mobile app and that information was synchronized.

OS detection can be enabled or disabled in the settings. It is enabled by default.

OS detection algorithm

Before Termius executes a script to detect OS, it finds out which shell runs on the server, which is done like so:

echo $SHELL
exit;

If the above script doesn't return an error, Termius runs one of the scripts below, depending on the shell being used on the server.

if set name (uname) = "Linux"
cat /etc/*release
else
uname
end

HISTFILE=;
SA_OS_TYPE="Linux"
REAL_OS_NAME=`uname`
if [ "$REAL_OS_NAME" != "$SA_OS_TYPE" ] ;
then
echo `uname`
else
DISTRIB_ID=\"`cat /etc/*release`\"
echo $DISTRIB_ID;
fi;
exit;

If any of the scripts mentioned in this section returned an error, Termius checks whether or not RouterOS is installed on the server:

:put [/system resource get platform]

Turn OS detection on or off
