DynDNS blocked me

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 Erik rewrote ez-ipupdate (which is no longer maintained) to be complete php.

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:

Dear Valued Customer:

The hostname, myaccount.homedns.org, in account myaccount, has been blocked for
abuse. This action has been taken due to the receipt of multiple updates
originating from the same IP address.

Please note, updates which result in the IP address associated with a host
changing are NOT considered abusive. Only those updates which result in no
change to the host are abusive. Please take a moment to review our Update
Abuse Policy here:

Show us your system logs.

Also show us /etc/crontab

/etc/crontab:
$ less /etc/crontab

HOME=/var/log

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.
however, I seem to always get the same IP address on every renewal.

I'll look further into the script.

You're cache file still reads 0.0.0.0?

Did it ever succeed?

mickeybyte

nope, cachedIP is always 0.0.0.0, so when it compares wanip with cacheIP, it's always different

sullrich

That's wild. Try unblocking yourself and watching the first run of the dyndns client, if the provider gives a ok message it should update the cache file.

mickeybyte

Let's look at the function DetectChange:
function _detectChange() {

log_error("DynDns: _detectChange() starting.");

$currentTime = time();

$wan_ip = get_current_wan_address();
$this->_dnsIP = $wan_ip;
log_error("DynDns: Current WAN IP: {$wan_ip}");

if (file_exists($this->_cacheFile)) {
if(file_exists($this->_cacheFile))
$contents = file_get_contents($this->_cacheFile);
else
$contents = "";
list($cacheIP,$cacheTime) = split(':', $contents);
$this->_debug($cacheIP.'/'.$cacheTime);
$initial = false;
log_error("DynDns: Cached IP: {$cacheIP}");
} else {
conf_mount_rw();
$file = fopen($this->_cacheFile, 'w');
fwrite($file, '0.0.0.0:'.$currentTime);
fclose($file);
conf_mount_ro();
$cacheIP = '0.0.0.0';
$cacheTime = $currentTime;
$initial = true;
log_error("DynDns: No Cached IP found.");
}

/* use 2419200 for dyndns, dhs, easydns, noip, hn
* zoneedit, dyns, ods
*/
$time = '2419200';

$needs_updating = FALSE;
/* lets deterimine if the item needs updating /
if ($cacheIP != $wan_ip) {
$needs_updating = TRUE;
log_error("DynDns: cacheIP != wan_ip. Updating.");
}
$update_reason = "Cached IP: {$cacheIP} WAN IP: {$wan_ip} ";
if (($currentTime - $cacheTime) > $time ) {
$needs_updating = TRUE;
log_error("DynDns: More than 28 days. Updating.");
}
$update_reason .= "{$currentTime} - {$cacheTime} > {$time} ";
if ($initial == TRUE) {
$needs_updating = TRUE;
$update_reason .= "Inital update. ";
log_error("DynDns: Initial run. Updating.");
}
/ finally if we need updating then store the
* new cache value and return true
*/
if($needs_updating == TRUE) {
return TRUE;
} else {
return FALSE;
}

log_error("DynDns debug information: {$update_reason}");

}

especially the last part here
in comments, it says:
/* finally if we need updating then store the
* new cache value and return true
*/
if($needs_updating == TRUE) {
return TRUE;
} else {
return FALSE;
}

but I don't see anywhere in the script some code that realy updates the cache file?

sullrich

Look further up:

if ($this->_detectChange() == FALSE) {
$this->_error(10);
} else {
if ($this->_dnsService == 'dyndns' ||
$this->_dnsService == 'dyndns-static' ||
$this->_dnsService == 'dyndns-custom' ||
$this->_dnsService == 'dhs' ||
$this->_dnsService == 'noip' ||
$this->_dnsService == 'easydns' ||
$this->_dnsService == 'hn' ||
$this->_dnsService == 'zoneedit' ||
$this->_dnsService == 'dyns' ||
$this->_dnsService == 'ods')
{
$this->_update();
} else {
$this->_error(6);
}
}

mickeybyte

Sorry,

there is in function CheckStatus at the end:

if($successful_update == true) {
/* Write WAN IP to cache file */
conf_mount_rw();
$file = fopen($this->_cacheFile, 'w');
fwrite($file, $wan_ip.':'.$currentTime);
fclose($file);
conf_mount_ro();
}

but it doesn't seem to do it I guess.
