APE over SSL using stunnel in cpanel server

Refer To APE installation in cpanel server here

1) In order for APE to work with stunnel, make sure that the stunnel version in the server should be less than 4.3. Centos and RHEL 5 will most probably have stunnel installed already. If not, install stunnel.

2) Now we need to create a conf for ape.
vi /etc/stunnel/ape.conf and add the following to it.


cert = /etc/stunnel/stunnel.pem
debug = 7
output = /etc/stunnel/stunnel.log
;disable delay DNS lookup for ‘connect’ option
delay = no
;no time to wait for close_notify!
TIMEOUTclose = 0
[ape]
accept = 1.2.3.4:443
connect = 1.2.3.4:80

Create a file for stunnel log.


# touch /etc/stunnel/stunnel.log

3) Now generate a CSR and key for *.ape.divya.com


# cd /etc/stunnel
# openssl req -nodes -newkey rsa:2048 -out csr.pem -keyout stunnel.pem

FTP login not working, but cpanel does

At times, you may get issues like, the cpanel login details may be working, but the same won’t work for FTP. As you are aware, cpanel and main FTP login details are always same. Resetting the password may not help in this case. Then check if a file named /etc/ftpusers is present in the server and if your username is included there.

Switch Account Option Disappears

Sometimes, when you login to an account’s cpanel as reseller, there should be a drop down box to switch to the cpanel of various accounts under that reseller. If it is not present, you can check the following things.

In WHM -> Tweak Settings -> make sure the following option is not checked.

Disable login with root or reseller password into the users’ cPanel interface. Also disable switch account dropdown in themes with switch account feature.

Sometimes, the problem can be with only one or two domains. All accounts’ cpanel may be listing the drop down, but when you enter into one the drop down just vanishes.

In that case, it could be a problem with the account password. Try resetting the password of that account and see if that solves the problem.
