# Extended traceroute plugin [(Download the MKP package)](/../../../-/raw/master/active_check_traceroute.mkp "Download MKP package")

This is a extension for the original CheckMK traceroute plugin (Routing)

adds the following options:

- service description suffix
- alternate destination address
- UDP method (without increasing the port for each probe)
- destination port for UDP/TCP path trace
- max hops
- queries per hop
- source address
- source interface (needs root permissions)
- perfometer

**Note: Source address and source interface uses the "shell=True" option in in the "subprocess.Popen" command. This is insecure, so be careful.**

To disable this options you need to comment out the line `shell = True` in [~/lib/nagios/plugins/check_traceroute](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/active_check_traceroute/-/blob/master/lib/nagios/plugins/check_traceroute) like this.

```
    if (source_int is not None) or (source_addr is not None):
        cmd = ' '.join(cmd)
        # shell = True

```

**Note**: the original TCP path trace option also needs root permisions.
