os-ddclient checkip - randomly stopped working today using any given IP check service

[ilikenwf]

I am afraid I can't tell you what caused this issue as no settings have been altered - the latest changes were just installing the latest minorversion update to OPNsense 22.1.10 and I have yet to have a chance to restart and try again, but even in the shell, calling checkip manually as so:

/usr/local/opnsense/scripts/ddclient/checkip -i em0 -t 1 -s nsupdate.info-ipv4

Results in "None" with any of the available services.

If I replace the cmd called in the ddclient.conf with:

cmd="/usr/local/bin/curl -sB icanhazip.com",

It works properly.

don't force an interface? your curl command uses the default route, checkip is set to force em0

[ilikenwf]

I tried both with and without an interface forced with no luck - checkip, regardless of the settings and service chosen, always fails. Not sure if there's a routing issue or what - I can manually pull with curl the same URIs used by checkip with success, I should mention.

[AdSchellevis]

the script basically uses curl underneath

https://github.com/opnsense/plugins/blob/fc2c08b029e6625be9ba12229093a7c674308ab3/dns/ddclient/src/opnsense/scripts/ddclient/checkip

which with the chosen options would render into :

/usr/local/bin/curl -m 10 --interface le1 https://ipv4.nsupdate.info/myip

maybe nsupdate isn't reachable from your location, there are many other options to choose from in the list icanhazip.com just isn't one of them

I had this same issue, the problem was the python script /usr/local/opnsense/scripts/ddclient/checkip always returning None. This script calls the various services via curl, which is hard coded to timeout after 10 seconds. Updating the script to timeout after 15 seconds fixed the issue for me...

I can confirm this fixes it for me. Can we get this to be a configurable or increase the default? 30 seconds for something like this would still be sane since it's not a time intensive operation.

It wouldn't be bad either to have icanhazip.com added as a provider since all it does is puke out an IP address...

[AdSchellevis]

just open a pull-request and we'll review it, it's not very difficult to add another provider to the list.

[ilikenwf]

I'll try and get around to that and a separate one for the timeout perhaps.
