After the upgrade to CSF 12.02 the login failure daemon is blocking IP addresses from countries that are listed in CC_IGNORE!

Posted: **09 Apr 2018, 17:20**

Also note that I'm using the CSF cluster functions and its happening across all servers now

I've disabled the LFD triggers on all our servers until this can get fixed.

1. What do you have listed in CC_IGNORE and what is CC_LOOKUPS set to (exactly as set)?
2. Please provide a log line with an IP that should be ignored by that list so we can test

The code for CC_IGNORE has not changed since v12.00 was released with the new lookups.

Note: Edited a few times

Looking at the code, this issue can arise if you have listed the country codes in lower-case. This has always been the case though.

If they are listed in uppercase and the IP resolves to a country I'm unable to recreate an issue, so will need the setting and log lines.

# CC_LOOKUPS must be enabled to use this option
CC_IGNORE = "CA"

We have always allowed Canada as that is where all our servers are from. After the upgrade within an hour we got about 20 calls from Canadian clients getting blocked.

I've emailed your sales email account with screenshots to better describe it.

I need an actual log line that triggered a block that should have been ignored. I also need the CC_LOOKUP setting. As I said, we're unable to recreate a problem.

Have you also checked on the server that triggered the block that the GeoLite2 files are actually listed in /var/lib/csf/Geo/ that corresponds to the CC_LOOKUP setting, i.e.they have been downloaded unzipped by lfd from /var/log/lfd.log?

On all servers:

Code: Select all

CC_LOOKUPS = "1"

On the older servers (centos 5)I'm seeing this:

Code: Select all

On the newer servers (Centos 7) I'm seeing this:

From the lfd log (server is Centos 6):

After looking at the logs maybe this causing the issue on the newer server?

Code: Select all

Apr  9 08:47:26 web4 lfd[13105]: CC Error: Unable to retrieve GeoLite2 CSV Country database [http://geolite.maxmind.com/download/geoip/database/GeoLite2-Country-CSV.zip] - Unable to rename /var/lib/csf/Geo/GeoLite2-Country-CSV.zip.tmp to /var/lib/csf/Geo/GeoLite2-Country-CSV.zip: No such file or directory

Update. OK so I've re-enabled the triggers and they seem to be working on the new servers.

I manually copied the new /var/lib/csf/Geo directories from the newer servers over to the older server and it looks like everything is working now.

1. I think that the new country unzip routines don't work on those legacy centos 5 servers.

2. I also think that after you do a csf -u there might be a race condition that happens if the country DB isn't downloaded yet with the switch from the old legacy to new geolite 2 DBs where IPs might get blocked ..
