Clamd FAILED :: Starting Clam AntiVirus Daemon: LibClamAV Error: cl_cvdhead: Can't read CVD header in /var/clamav/daily.cld

Posted by Mayur's BLOG

If you are getting following error while restarting the clamd
--------------------------------------

Stopping Clam AntiVirus Daemon:                            [FAILED]
Starting Clam AntiVirus Daemon: LibClamAV Error: cl_cvdhead: Can't read CVD header in /var/clamav/daily.cld
LibClamAV Error: cli_loaddbdir(): error parsing header of /var/clamav/daily.cld
ERROR: Malformed database
                                                           [FAILED]
--------------------------------------


That means the DBs are corrupted. Do this:
--------------
cd /usr/share/clamav/
--------------
Empty the content of these 3 files:
daily.cvd
main.cld
mirrors.dat
Then run this command to download fresh copies for your DBs:

/etc/cron.daily/freshclam

Although this is not necessary, but restart clamd:

Code:
/scripts/restartsrv_clamd
Hope this helps!

Run FTP on multiple ports (Proftpd & Pure-FTPD)

Posted by Mayur's BLOG

In many cases you don't want to allow default FTP port which is 21 and need to set FTP on different port OR you want both for FTP. Here I am specifying the steps to configure FTP on multiple ports and I am using custom port number 8226 here for FTP:

Pro-FTPD

in pro-ftpd, its quite simple and you just need to specify the different port in "/etc/pure-ftpd.conf" as given below:
---------------------
Port                            8226
PassivePorts    30000 50000
---------------------

On my testing server I've added these lines above following line which works fine:
---------------------
# Umask 022 is a good standard umask to prevent new dirs and files
---------------------

Once you are done with the changes, restart the service:
---------------------
/etc/init.d/proftpd restart
---------------------

make sure it is working through following command:
---------------------
root@[~]# netstat -lpn | grep ftp
tcp        0      0 :::8226                     :::*                        LISTEN      854817/proftpd: (ac 
tcp        0      0 :::21                       :::*                        LISTEN      854817/proftpd: (ac 
---------------------

Now try connecting with both ports and it should work.

Pure-FTPD

Pure-FTPD configuration is bit lengthy but it is always recommended to use pure-ftp instead as Pure-FTPd is generally regarded as faster FTP than Pro FTPd. So here is the configuration for running pure-ftpd on multiple ports

1. Make a copy of default pure-ftpd.conf file
---------------------
cp -p /etc/pure-ftpd.conf /etc/pure-ftpd-8226.conf
---------------------

2. Edit the file /etc/pure-ftpd-8226.conf
---------------------
vi /etc/pure-ftpd-8226.conf
---------------------

3. Find and replace the lines
---------------------
# Bind 127.0.0.1,21
With
Bind 0.0.0.0,8226
---------------------

4. Now make a copy of the start-up script and run with the new config as a separate service:
---------------------
cp -p /etc/rc.d/init.d/pure-ftpd /etc/rc.d/init.d/pure-ftpd-8226
---------------------

5. Edit the /etc/rc.d/init.d/pure-ftpd-31 to load with the new config.
---------------------
vi /etc/rc.d/init.d/pure-ftpd-31
---------------------

6. Find and replace the lines
---------------------
$DAEMONIZE $fullpath /etc/pure-ftpd.conf -O clf:/var/log/xferlog $OPTIONS –daemonize
With
$DAEMONIZE $fullpath /etc/pure-ftpd-8226.conf -O clf:/var/log/xferlog $OPTIONS –daemonize
---------------------

7. Now start the new service.
---------------------
/etc/init.d/pure-ftpd-8226 start
---------------------
Done, now make sure that both ports are working
---------------------
root@vault [~]# netstat -lpn | grep ftp
tcp        0      0 0.0.0.0:6497                0.0.0.0:*                   LISTEN      7589/pure-ftpd (SER 
tcp        0      0 0.0.0.0:21                  0.0.0.0:*                   LISTEN      23093/pure-ftpd (SER
---------------------
Note :: 
# If you want to stop serving port 21 for FTP with pure-ftpd, simply stop the default service:
---------------------
/etc/init.d/pure-ftpd stop
---------------------
and restart another start-up script
---------------------
/etc/init.d/pure-ftpd-8226 restart
---------------------
That's it.

# The another important thing is that you need to allow passive port range in custom conf file (/etc/pure-ftpd-8226.conf), simply remove the comment (#) in front of below line:
---------------------
PassivePorts    30000 50000
---------------------
# Make sure that passive port range (30000:50000) and custom port (8226) is open in firewall if you have any

I hope this post will make your work easier :-)
