Description

When configuring remote syslog servers in status_logs_settings.php each server is entered as IP[:port]. Port 514 is assumed if no port in entered.

However the page will allow you to enter a range on invalid values there such as:

5140
514:5140
192.168.1.105140

All result in invalid syslog configs.
Some are interpreted as IP addresses resulting in sending syslog data to an unintended target. For example 514 is seen as 0.0.2.2.

Tested 21.05 and 2.5.2.b.20210604.0300

OS interprets numeric-only value as decimal IP address:

[2.6.0-DEVELOPMENT][root@pf41.localdomain]/root: ping 10
PING 10 (0.0.0.10): 56 data bytes
[2.6.0-DEVELOPMENT][root@pf41.localdomain]/root: ping 255
PING 255 (0.0.0.255): 56 data bytes
[2.6.0-DEVELOPMENT][root@pf41.localdomain]/root: ping 256
PING 256 (0.0.1.0): 56 data bytes

Tested on the:

2.6.0-DEVELOPMENT (amd64)
built on Mon Jul 26 14:27:42 EDT 2021
FreeBSD 12.2-STABLE

The validation check works only in the first input filed. If you insert a valid value in the first field and an invalid in the second and third, it will accept the settings.

Please check.

It works fine. It considered my entry as FQDN (192.168.33.33333) and passed the validity check.

The ticket can be resolved.
