DynDNS blocked me

Hi,

better activate ssh and use a ssh session to do it.

You can however run the commands in the exec.php window, one at a time, but a "cd" won't work, because each time you are indeed again in the default directory

Thanks mickeybyte ;)
Cheers

EDIT: I have successfuly sshed to my box.
I am currently in "/etc" and I can see the file "crontab".
But now what do I do?
What did Scott mean by "update_file.sh"?
TIA

mickeybyte

you actually don't need to "cd" to that dir

in fact, you only need to enter the commands like Scott said
so at your shell prompt you type:

update_file.sh /etc/crontab <enter>==> updates the crontab file
update_file.sh /etc/inc/dyndns.class <enter>==> updates the dyndns.class procedure
shutdown -r now <enter>==> reboots the firewall

I think you might as well update the dyndns.class file also before rebooting

So you could have just entered those commands one at a time in the command box using the webinterface (in stead of <enter>you click <submit>)</submit></enter></enter></enter></enter>

Thanks mickeybyte ;).
BTW how is that dyndns service behaving so far?
Cheers

EDIT:

# update_file.sh /etc/crontab
trying to fetch latest /etc/crontab
fetch: http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/etc/crontab?rev=1;content-type=text%2Fplain: size of remote file is not known
/etc/crontab                                           465  B  110 kBps
# update_file.sh /etc/inc/dyndns.class
trying to fetch latest /etc/inc/dyndns.class

/etc/inc/dyndns.class                                   20 kB   44 kBps

This is what I got.
Is this ok?
Cheers

mickeybyte

until now still running fine (fine = not being blocked)

however in the logs it still says every hour cache ip (0.0.0.0) != wan ip (current ip) although it did not change!

Strange I think, because I used to have m0n0wall and I had never any problems with that system.

Nevertheless, I'll keep you informed if my DynDNS account status changes! ;)

sullrich

#1. There was a bug where the cache was being updated every time. Now the cache will not be updated unless it has received a OK status from the provider. So that means your cache statement will be updated as soon as you're ip changes.

#2. We do not use any of the same code for DYNDNS. Erik rewrote ez-ipupdate (which is no longer maintained) to be complete php.

mickeybyte

Great :)

And thanks for support!

rds_correia

Thanks for clarifying this for us Scott.
Cheers

hoba

btw, that also is the reason why the dyndns providerlist of m0n0 and pfsense is different.

mickeybyte

oops :-[, never saw the difference…

Well, it did last a day longer than before, but there it was again in my mailbox today:

Show us your system logs.

Also show us /etc/crontab

mickeybyte

/etc/crontab:
$ less /etc/crontab

Systemlogs are more difficult, unless you can tell me where I can find them on pfSense (not the webinterface, but the files itself)? Problem is I sent all syslogs tot a syslog daemon, but last night my switch gave up, and I've just repaired the problem, so I don't have any logs in my syslog daemon since late last night. I'll see if I can already find something in there.

sullrich

From a shell:

cat /var/log/system.log | grep Dyn

mickeybyte

looking at the crontab, I've noticed the dyndns line stating
1 0-1 * * * …
what exactly does it mean? when does it run.

I'can only find logfiles on the firewall since I've rebooted it a few hours ago, and there I noticed it updated it every 10 seconds?
In my syslog daemon, I can only find logs until 12 o'clock last night and there it shows up every once an hour, but still not blocked.
The mail that said I was blocked again came around 3h30 this morning

sullrich

The first 1 is first minute. I thought 0-1 is a randomized midnight to 1 am.

I'll change it to run at 1:01 am

Run update_file.sh /etc/crontab again

mickeybyte

Scott,

If you ask me, that's not the best solution.
say, my Ip changes at 4am, it will take until next day 1h01, until my dyndns will get updated? or am I getting it wrong here?

Still can't resist to bring up the CachedIP problem again. That's where the problem is according to me, if it can correctly compare cachedIP and current IP, and only contact dyndns if that's different, what actually does at this time, but cachedIP is always 0.0.0.0.

I'll take a look at the dyndns.class file to see if I can find anything there (not that I'm a freebsd geek, but I do have some programming skills and some linux knowledge)

The dynamic dns client is run after ANY ip change. The only reason for the once a day check is to check back in after 28 days to keep the item from expiring.

seems like it is updatin every hour, of half an our. This could be related to my DHCP renewal time. Sometimes it's 1800 seconds, other times it's 3600 seconds.
