[Serusers] SER/FIFO not accessible

[Steve B.]

I am new to SER. I have installed SER 0.9.6-2 on a fresh Kubuntu server using apt. I have been able 
to get SER to run using the sample ser.cfg files (only changing module paths from /usr/local/lib... 
to /usr/lib/...).

I am trying to setup the mysql support. In a nutshell, when I run serctl I get an error:

# serctl add sbelt at ser.mytestsite.com sbelt sbelt at mytestsite.com
MySql password: (here I enter 42serro11)
error: SER/FIFO not accessible: 2
#

Am I using the correct password? I am not sure which Mysql Password is being requested here. I have 
also tried the mysql root password with the same result.

I have seen other posts similar that seem to indicate it is permissions on the /tmp directory. I 
tried adding to ser.cfg fifo_mode=0777. I have verified the current user can write to the /tmp 
directory. Frankly, I do not know if this /tmp/ser_fifo is all a red herring.

Thanks for any help on how I can figure out what I am doing wrong.

Here is my ser.cfg
