Logging my daily changing WAN-address

It changes , => you get a mail.

Interesting. The problem with that, having many VPN-clients as gateways makes a lot of gateway-alerts and with that emails. So I would need to fight that first. And I recently changed my email server and now it is more cumbersome creating this types of rules. Maybe I should look into that anyways.

Keep in mind that Dyndns, triggered when a WAN type interface event happens, will only update the IP, and send a mail if the previous WAN IP was different as the current, new one.
So, you'll get a mail and if you do not want a mail, you know now how to disable the mail notif] ( see here - and 7 lines lower for the IPv6 equivalent).

Hi, I propose you another solution (if you like and you are not to shy to edit a system file)

Edit this file:

/usr/local/sbin/ppp-linkup

(this file gets executed each time the pppoe triggers a new connection (implicit a new IP))

attach at the end of the file (before the "exit 0")

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

In this example the destination is a file in the root directory: /root/iplog/iplog.log (you can choose another destination as you wish)

@fireodo

mkdir -p /root/iplog
touch /root/iplog/iplog.log

If for some reason, the sub folder didn't exit (because pfSense was re installed, or some &@$!!¤ deleted the "iplog" folder in /root/), its created.
Same thing for the file "iplog.log" : if it didn't exist, a zero byte "iplog.log" will be created.

and from now on its happy appending :

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

Thanks for the completion! Also after a pfsense-update the "ppp-linkup" file has to be edited again.

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

Of course, but maybe someone else read and want that too ...

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

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.

@Gertjan said in [solved] Easy solution for logging my daily changing WAN-address:

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 ... :-)
