I would say, that the rule of thumb is that you should quote where a string is expected in values. Our grammar accepts strings without quotes, but then it is possible to have collision with config keywords (e.g. syslog is a keyword). So, in case of netmask(), this one should be used: netmask("127.0.0.1/32").
I think that maybe some filters, the ones that take strings essentially, are quoted, and not the ones that take numeric data. Is that correct?
Exactly, just like I described above. Regards, Gabor ________________________________ From: syslog-ng <syslog-ng-bounces@lists.balabit.hu> on behalf of Faine, Mark R.

Do not follow guidance, click links, or open attachments unless you recognize the sender and know the content is safe. What is the policy on quoting values in filters? In the docs it seems that sometimes they are quoted and other times they are not. For example, are these equivalent: netmask (127.0.0.1/32) and netmask(“127.0.0.1/32”) I think that maybe some filters, the ones that take strings essentially, are quoted, and not the ones that take numeric data. Is that correct? Thanks, -Mark
