Port.pm doesn't wait if iptables is locked by another process

[atika]

Hi. I found this in my monitorix logs (Ubuntu trusty) :

Another app is currently holding the xtables lock. Perhaps you want to use the -w option?
Use of uninitialized value within @i_in in concatenation (.) or string at /usr/lib/monitorix/port.pm line 278.

Hi,

You're right, it looks like newer iptables versions have this new -w option, but including that option will generate errors in older versions of iptables. I need to investigate further on this.

I'll keep you informed. Thanks!

Hi, It's iptables v1.4.21 on Ubuntu Trusty 14.04. I having the same problem on my scripts failing when Iptables was used by another process, I have added the --wait option, it seems to work now.

Please, check the last commit and let me know if it works as expected. Thanks.

Hi. I have updated all files and I no longer have the error messages in the logs. It's seem to work. I do not know if I can test something else or run the script manually. Thanks. I have another message in the logs, I create a new issue for it.

OK, let's close this one.
