Using exec probably is enough for unix systems, but you might want to use a more direct approach, eg. for use on multi-platform scripts

Digging around, the nsicmp TCL package seems to provide such ICMP ping support : https://bitbucket.org/naviserver/nsicmp/overview

Just exec the regular ping binary and catch its error code: Unix ping returns 0, 1 or 2 depending on whether it suceeded in verifying the host's reachability of not.

You'll probablty need to use -n N and -q options to ping and redirect its stdout and stderr to /dev/null.

For an example on how to call an external program via exec and trap possible errors see the "Unix" section down in the exec manual page.
