matches null string many times is regex

[bduong]

Hello,
I running a trail version of PROXMOX 2.1. I am getting multiple warning in the Realtime Logfile Query. The following error.

Feb 21 11:53:50 proxprox 15840 WARNING: ^* matches null string many times is regex; marked by <-- HERE in m/^* <-- HERE .******/ at /usr/share/perl5/Proxmox/RuleDB/WhoRegex.pm line 94



--- ******* / - item in blacklist



This will repeat very offten with all items in the blacklist. Is this normal?

Thanks!!

Never mind, I found the problem. It’s a user error. I did not use the proper parameter in the regular expression.

Same error

It is described in short in the reference documentation: https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmg_mailfilter_regex
usually this error comes from a misunderstanding of regular expressions vs. globs:
* for regular expression to match 'anything' the expression is '.*' (for globs it is '*')
-> check your rule system for this

I hope this helps!

example, that is, instead of *@zopid.ru you need to write .*@zopid.ru?

yes - just try it and watch the logs

Dear i have received warning below. Are is critical one or can ignore. Why is generATED
WARNING: ^* matches null string many times in regex; marked by <-- HERE in m/^* <-- HERE @*.work$/ at /usr/share/perl5/PMG/RuleDB/WhoRegex.pm line 90

as explained above (https://forum.proxmox.com/threads/matches-null-string-many-times-is-regex.351/post-328816)
it seems you wrote a glob expression, but a regex is needed
instead of:

*@*.work

use:

.*@.*\.work

I hope this helps!
