How Termius Detects the Server's OS

To detect the OS installed on a server, Termius executes a script. It happens when the connection is being established (in the exec channel) and if Termius hasn't already detected the OS. Having identified 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 Pro or Team account).

OS detection can be enabled / disabled in the settings, and is enabled by default. Disabling OS detection will not cause the logos of detected OSes to disappear.

Note: A server may return information about the installed OS during connection process / handshake. Termius will use that information and show the OS logo, even when OS detection is disabled.

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
