Logging my daily changing WAN-address

If you have a dyndns client running on the WAN it should only notify you when the WAN address changes.

I'm pretty sure bob.dig can make a patch out of it, so it can be re installed with a click ^^

Actually no, you must mistake me for someone else. But thank you and @fireodo for that solution. I think, I like it the most so far.

True, but any gateway event will also trigger emails, as far as I remember, and with 10+ flaky privacy-VPN-clients, that are WAN-type interfaces, this becomes very annoying, I can tell you.

I get it.
Still, the Dyndns setp will only send a mail IF the WAN IP actually did change.
If the "do something with the WAN interface" is called many time, it doesn't matter : only if the IP changed, you get a mail.
If it changes x times a day, you will get x mails a day, true.

Marked solved, thanks guys.

If someone reputable wants to make a site "pfSense Helper Scripts", I wouldn't mind.

Hi,

in case of using if_pppoe (in pfsense 2.8.0) what file would have to be edited and attach these lines

cat /tmp/pppoe0_ip >> /root/iplog/iplog.log
date >> /root/iplog/iplog.log

for having the WAN-IP get logged? (the /usr/local/sbin/ppp-linkup is not used anymore)

Thanks and nice sunday,
fireodo

You could probably add something to pppoe-handler. But that's PHP not a shell script.

Thanks - I'm not a PHP guru - do you have a "code" example?

stephenw10

Ha, I thought you might ask that and...nope not off hand. I'm no php guru either!

But if you're just logging the IP it's probably a one liner....

Bob.Dig

Maybe @Gertjan knows how to do it and can give detailed instructions how to do it for a noob like me.

Doesn't exist anymore ?
I'm not using 2.7.2 or 2.8.0, - not using the pppoe or the new pppoe.

This (you mentioned) still exist but the executable /usr/local/sbin/ppp-linkup, is not used with the if_pppoe, so the lines that where attached at this file:

cat /tmp/pppoe0_ip >> /root/iplog/iplog.log
date >> /root/iplog/iplog.log

doesn't function anymore. stephenw10 suggest to modify the /usr/local/sbin/pppoe-handler file but I'm not familiar with PHP ;-)

Or how to do it with the DDNS-thingy.

I will look, until I find a solution I stay with mpd as all the time before 2.8.0 ... :-)

Hi,

i found a solution everybody interested is invited to try :-)

I made a shell script file called "logip" with following content:

#!/bin/sh

# IP-Logging
cat /tmp/pppoe0_ip >> /root/iplog/iplog.log
date >> /root/iplog/iplog.log

and placed in "/root/bin/" and made it executable.

After that I modified (attention - this is a original pfsense file!!!) the file "/etc/rc.newwanip" attaching at the end (before the "?>" this line of code:

shell_exec('/root/bin/logip');

The rc.newwanip is executed each time the system gets a new WAN IP so it should work. (I tested here and it works).
The "bad" thing is that the "rc.newwanip" has to be edited each time the system gets an upgrade/update ...
If someone gets a more "elegant" solution I'am open to it :-)

Regards,
fireodo

You could create a patch that adds that line to rc.newwanip and set it to auto-apply.

Yes that would be an option!

But now I found a new "problem": Snort cannot handle the pppoe0 interface (with if_pppoe) and exits with this error:
"FATAL ERROR: Cannot decode data link type 51"
so there is more work to do I switched back to "mpd" because i need Snort working ...

Hmm, using in-line mode?

No, legacy mode ...
