Anonymize -p password

I need to anonymize -p passwords that are appearing in syslog.

Used
props.conf
[syslog_log_control]
source::/var/log/syslog
TRANSFORMS = auth-password-anonymizer

transforms.conf
auth-password-anonymize]
REGEX = -p [0-9A-Za-z]\w{9,255}
FORMAT = $1-p =########$2
DEST_KEY = _raw

I am seeing syslog Cannot parse into key-value pair errors

02-01-2018 00:17:29.320 +0000 WARN ProcessTracker - (child_183__Fsck) IniFile - /opt/splunk/etc/slave-apps/_cluster/local/props.conf, line 95: Cannot parse into key-value pair: source::/var/log/syslog

Please advise

Thanks,

NP

You have no capture groups defined in your regex, and thus $1 and $2 can't be used. Try this:

REGEX = ^(.*)-p [0-9A-Za-z]\w{9,255}(.*?)$
FORMAT = $1-p ########$2

Though it may make sense to use SEDCMD here instead, because you can more easily replace part of a string (instead of rewriting the entire string from components, as you're doing above).

In props.conf:

[syslog_log_control]
SEDCMD-anonymize = s/-p [0-9A-Za-z]\w{9,255}/-p ########/

Thanks a lot to both .

are you trying to set the source to /var/log/syslog? Or is that the source you want to apply the transform to? I don't think your props is doing either correctly, which is why I think it's barking at you.

but it also looks like you may have typed that in above or missed some bits during copy/paste, so not sure if that's exactly how your config looks?
