Locked out of my own firewall

CSF is the first culprit if you are locked out of your own server firewall after too many failed login attempts from a certain IP.

The block was in your firewall, not cpHulk.
The IP was listed in /etc/csf/csf.deny and /var/lib/csf/csf.tempip and /var/lib/csf/csf.tempban
You can whitelist the IP in your firewall by placing the IP in /etc/csf/csf.conf, then running csf -r

Next you can place your external IP in the whitelist of cPHulk:

WHM > Security Center > cPHulk brute force protection > White/Black list > Quick Add your current external IP to: White List (Trusted IP List)

To find your external IP:

http://cmyip.com

SMTP Reverse DNS Mismatch Warning – Reverse DNS does not match SMTP Banner

This alert on an SMTP check on Mxtoolbox is trivial.

It could be because your outbound (sending) mail server is blocking un-authenticated port 25 use by spammers. Instead you can authenticate (login) on port 487 to send email.

This from Mxtoolbox:

“Also, the banner mismatch is just a warning. There’s nothing that says that having a mismatch (or no hostnme in your banner at all) will cause you to have difficulty sending or receiving mail, it’s really more of a best practice.”

If you cannot login with SFTP or SSH but can login with FTP and WHM and Cpanel

This is likely that you need to restart the SSH service. SFTP uses SSH not FTP.

“I just had to restart the SSH service from WHM

Sometimes, SSH will crash

If it does, just login to WHM and restart SSH”

3. Click on the “Load Previous Config” button (if exists);
4. Select “GD” option and any other PHP option you may need;
5. Uncheck the “Skip Apache Build if up to date” option;
6. Click “Start build” button at the bottom of the screen and wait 15-30 minutes.

StripeXS addon fails with white screen in WHMCS when viewing info

This usually means that the server doesn’t have the php-mbsting enabled.

When rebuilding Apache with Easy Apache, on step 6 (exhaustive options), scroll down and check php-mbstring.

Then let it compile as usual.

Mine had an alert near the end of the make process “No package php-mbstring available.
Error: Nothing to do”

However it fixed the problem!

Another way to enable php-mbsting is manually run in SSH shell as root:
“yum -y install php-mbstring”, then “service httpd restart”
Mine couldn’t find php-mbstring, but that’s probably just a matter of adding the right repository to yum.
More info on this here: http://www.webhostingtalk.com/showthread.php?t=873543

In my phpinfo screen, my server now says this:

mbstring

Multibyte Support enabled
Multibyte string engine libmbfl
HTTP input encoding translation disabled

mbstring extension makes use of “streamable kanji code filter and converter”, which is distributed under the GNU Lesser General Public License version 2.1.
