look for “Edit lfd ignore file” select csf.ignore – IP Blocking on dropdown list and click Edit button

Info for csf.ignore file is all IP addresses listed will be ignored by all lfd checks. Since it will be ignored so it won’t be blocked (automatically whitelisted)

You can change maximum message size by adding line

message_size_limit = 5M

on the first textarea of the Advanced Mode editor in WHM > Exim Configuration Editor. That will put a 5MB message size limit on email.

PS: the limit only affect is email is sent directly using Email Client, if using Webmail (Squirrelmail) there is another limitation set by PHP when uploading file. it’s variable upload_max_filesize, you can change the value on WHM >  PHP Configuration Editor. Restart apache to make sure variable.

This command will make your cpanel install is updated with latest version by force (replace all file). Detail here.

I recently changed the IP addresses of a server running ISPConfig 2 and stumbled upon this thread. Since the server was hosting many sites, I was looking for a more effecient way to update the IP for all the sites in ISPConfig. Thought I would share my solution in case anyone else has this issue.

Please note: this worked for me on ISPConfig 2 running on Ubuntu 8.10. Location of config files my be different depending on your system.

After you change the IP on the system, log into ISPConfig and replace the IP address under Management > Server > Settings. Then replace the IP address in config files:

xxx.xxx.x.xx represents new IP
yyy.yyy.y.yy represents old IP

Bind9

perl -pi -e 's/yyy\.yyy\.y\.yy/xxx.xxx.x.xx/g' /var/lib/named/etc/bind/*

Apache

perl -pi -e 's/yyy\.yyy\.y\.yy/xxx.xxx.x.xx/g' /etc/apache2/vhosts/*

Now, log into MySQL, use the ispconfig database, and run the following queries to update the IP in ISPConfig:

DNS Manager

UPDATE dns_a SET ip_adresse = 'xxx.xxx.x.xx';
UPDATE dns_isp_dns SET dns_soa_ip = 'xxx.xxx.x.xx';

ISP Manager

UPDATE isp_isp_web SET web_ip = 'xxx.xxx.x.xx';
UPDATE isp_isp_domain SET domain_ip = 'xxx.xxx.x.xx';

Of course, you will need to restart apache and bind. Now all sites should load and when you log into ISPConfig you will see the new IP for each site and all your DNS records. Go to one of your sites under ISP Manager, make a minor change and hit save so that ISPConfig rewrites the config files. Then verify that ISPConfig is using the new IP and you’re good to go.

Make sure all vmware service is running, especially vmware-hostd, vmware-mgmt. Like below

# netstat -pant

If not try to restart vmware-mgmt.

# /etc/init.d/vmware-mgmt stop

Kill the rest wmware-hostd PID, and start it again

# /etc/init.d/vmware-mgmt start

Update:
1. Try another browser if you can’t access VMWare Management Console (like. older IE, older Firefox or use Opera)

2. You should access your VMWare Management Console URL using the same name in your VMWare’s SSL certificate. In my case on the certificate I name the vmware server as vpsserver.myholding.com so I should type on browser. Create an A record for it if you don’t have it.

https://vpsserver.myholding.com:8333/

3. For Firefox 3.6 has been disable SSL2 support. To enable it type “about:config” in url then set security.enable_ssl2 into true.

qmHandle is a simple program which allows you to view and manage the qmail message queue.

The key features of qmHandle are:

• Freeware and open source, under the GNU General Public License;
• More information provided when reading queue contents compared to qmail-qread
• You can print queue statistics, like qmail-qstat, with color capabilities;
• You can view a message in the queue;
• You can remove one or more messages from the queue based on a criterion or use multiple delete requests each having its own criterion;
• Written in Perl, and therefore easily customizable and truly multiplatform.

The software will work on every Unix platform with Perl installed and qmail installed.

qmHandle can be downloaded qmHandle project homepage

For me qmHandle is a great tool and a must have for sysadmin for managing qmail queue system. Enough for explanation. Now let’s get started how to use it.

The first line 16923 (18, R) shows us the message ID (16923), and queue type (Remote or Local) in this case both of them are remote queue, which mean this message are sent from other mailserver. The rest of lines is header information for you to tell from where, to where, when, what subject and message size.

you can use -L or -R option to list message queue only from Local or from Remote

# qmHandle -L
Messages in local queue: 0
Messages in remote queue: 4

# qmHandle -R | more
16946 (18, R)

Now to see the body of message use -m option followed by message id

# qmHandle -m16197 | more

Dear team,=20

Mohon bantuannya, makasih

To display statistic only for local and remote queue, use

# qmHandle -s
Messages in local queue: 0
Messages in remote queue: 4

Send queued messages

If message failed to sent, they will be in queue for re-trying until it past queue life time.  You can try to send all queued messages by running

# qmHandle -a

Delete queued message

Okay now we came into our important section, before you use one of these options make sure qmail has stop to prevent corruption in queue message.

Delete 1 message, use -d option followed by message id

# qmHandle -d16197

Delete all messages

# qmHandle -D

Delete all queue messages with Subject containing “REPORT 14 JANUARY 2010″, remember Reply and Forward messages also will be deleted because the Subject is “Re: REPORT 14 JANUARY 2010″ or “Fwd: REPORT 14 JANUARY 2010″

# qmHandle -S"REPORT 14 JANUARY 2010"

Delete All messages, use it with precaution and make sure this is the right choice

# qmHandle -D

That’s all folks, now you know what to do with your queue system, just in case you sent the wrong email.
