Find this in the Pure-FTPd configuration file (/etc/sysconfig/pure-ftpd):

• # disallow uploads for anonymous users
• #–anonymouscantupload

Make sure the second line has the # in front of it, then restart PureFTPd.

/etc/sysconfig/pure-ftpd

thank you.

Run the following scripts:

1. /scripts/updatenow
   
2. /scripts/fixndc
   
3. /scripts/fixndc
   • The fixndc script needs to be run twice.

Issue the following commands in a terminal session:

• rpm -Uvh http://httpupdate.cpanel.net/fp-5.0-upgrade/frontpage/frontpage-5.0-0.i386.rpm

Issue the following commands in a terminal session:

1. /scripts/rebuildinterchangecfg
2. /usr/local/cpanel/bin/startinterchange

Issue the following command in a terminal session:

• rm -f /var/cpanel/objcache/whmnews

Most of the services can be restarted from WHM; however, you may need to restart them from the shell. You must be logged in as root to do this. All standard Linux services, such as HTTP, FTP, exim, cPanel/WHM, Interchange, MySQL, etc, have init scripts in /etc/rc.d/init.d/

root@host [~]# ls /etc/rc.d/init.d/
./ atd* exim* httpd.tmpeditlib kdcrotate* named* nscd* rawdevices* snmpd* yppasswdd*
../ autofs* filelimits* identd* keytable* netfs* portmap* rstatd* sshd* ypserv* 
anacron* bandmin* functions* ipaliases* killall* network* portsentry* rusersd* syslog* ypxfrd*
antirelayd* chkservd* gpm* ipchains* kudzu* nfs* proftpd* rwalld* xfs* 
apmd* cpanel3* halt* iptables* lpd* nfslock* radvd* rwhod* xinetd* 
arpwatch* crond* httpd@ isdn* mysql* nofsck* random* single* ypbind*

This is typical of what you will find in this directory. The main ones you should be concerned with are:

• cpanel3 — starts/stops cPanel and WHM. This includes Interchange, cppop, and cluster management services as well.
• exim — starts/stops the exim mail server.
• httpd — starts/stops the Apache web server.
• mysql — starts/stops the MySQL database server.
• named — Starts/stops the BIND DNS server.
• proftpd — Starts/stop the ProFTPd or Pure-FTPd (depending on which is enabled) FTP server.

Using these scripts is very easy. Let’s say that named/BIND is down and we need to restart it. As root, type:

• /etc/rc.d/init.d/named start

You should see it start up, with a green [OK] message on the left side of the shell/terminal window.

If you see a red [FAILED] message, check the message log.

• tail /var/log/messages

You should be able to see the error. If you cannot fix it yourself, contact tech support. Some of these services have more options than just “start” and “stop,” and other ways to do them.

Let’s say you have a lot of domains using your DNS server and you don’t want to stop and restart named just because you edited one domain. Type:

• ndc reload

If you make a minor change to the /usr/local/apache/conf/httpd.conf, but don’t want to restart it, type:

• /etc/rc.d/init.d/httpd graceful to do a graceful restart. A graceful restart finishes current requests before killing the child processes.

If you want to learn more about the commands a script offers, you can simply run the script without passing any arguments to it.

root@saturn [~]# /etc/rc.d/init.d/cpanel3 <br />Usage: /etc/rc.d/init.d/cpanel3 {start|stop|status|restart}

This lets us know we can start, stop, check the running status of the service(s), or restart it. If you can’t get a service to start, and don’t know how to fix it, contact tech support for assistance.

There are a few possible solutions.

Usually, /var is what fills up first. This is because /var holds all the system logs.

To see what directory or log is taking up all the room, start at the base. Issue the following commands from a terminal session:

1. cd /var
2. du -sh *

This will show how much space is used and available in each directory, as well as the file sizes of each file in the current directory. Examine the command’s output. Once you see what directory is taking up all the space, cd to it and type the same command again. Follow this searching pattern until you find the files taking up the space.

Once found, you can either delete the files or, if you’d like to save some of the most recent entries to it, you can type this:

1. tail -5000 filename > filename.new
2. mv filename.new filename
3. sync

This will copy the last 5000 lines from the file to a temporary file. Now you probably want to restart whatever service it is that created the file, to release its file lock.

The /usr directory also fills up sometimes, because of Apache. The first thing you should look at is usually the Apache logs.

1. cd /usr/local/apache
2. du -sh *

You will likely find that the logs/error_log or logs/access_log files are very large. At this point, you are free to delete them or use the tail trick above.

If you want to block access to your server for whatever reason, you will need to log into the shell as root. Your server should either have ipchains or iptables to help accomplish this. In this example, the attacking IP is 192.168.56.210.

Issue the appropriate command in a terminal session:

• If you are using ipchains: ipchains -A input -j DENY -p all -l -s 192.168.56.210/32
• If you are using iptables: iptables -A INPUT -s 192.168.56.210/32 -j DROP

If you just want to block access to one port from an IP :

• iptables -A INPUT -s 192.168.56.210/32 -p tcp –destination-port 23 -j DROP

The above would drop all packets from 192.168.56.210/32 to port 23 (Telnet) on the server.

There are many in-depth tutorials available on the Internet. Consult your favorite search engine for more information.
