No Access to my SME-Server
« on: February 26, 2014, 03:16:07 PM »
Hi
I'm new to this Forum and I apologies for my English.
I'm running a SME 8.0 Server for a while now. I use it primarily as a Calendar-Server with a SOGo-Installation.
Since two Days now, I have no access to this Server via the server-manager, nor the SOGo-Interface. I can log me in on the server, I can reach the web server (under construction), I receive the ping; but no chance with server-manager or an other access.

Can anyone help me?

Greetings
Luca

What happens when you try to access server-manager? What exactly do you mean by "an[y] other access"?

You will need to have skills at the command line to solve your problem. You will need to log in and look at log files, and use tools such as 'top', 'ps', 'netstat' etc to see what processes are running and what their status is.

There is no simple short answer to your questions.

When I try to access, I get an Timeout!
Other access would be SSH . There too I get a Timeout.
Sure. I'm not really good, but I know these sort of commands.

From a windows workstation behind your sme server, open a browser to grc.com & do a port scan.
This will check to see if required ports are open eg 443 for server manager, 22 (or whatever you use) for ssh etc & so on.

Log in as root at the command line & show output of

service httpd-e-smith status
(Should be something like
run: /service/httpd-e-smith: (pid 2033) 12660s, normally down)

service httpd-admin status
(Should be something like
run: /service/httpd-admin: (pid 2017) 12683s, normally down; run: log: (pid 796) 13157s)

service sshd status

Did you make any changes, install software, upgrade the server etc 2 days or earlier ago ?
If so what changes ?

Can you access the text based server manager ?
To access that, Log in as root to command prompt,
type
console
then select server manager option
Use the tab key & cursor keys or mouse to move around.

Also look in the log files eg /var/log/messages
around the time you try to access services that are timing out

Also look in the specific log files for those services eg httpd-admin

eg cat /var/log/messages

It is a little more difficult to read them without access to the GUI server manager

Try issuing the command
htop
& review the output
this is a good way to list services & their status. You need to see if httpd-admin & sshd are running & so on.

As Charlie says there are many places & things to look at to determine where the problem lies, but got to start somewhere.

Hi Janet

Thank you for your help.

In summ I can tell you:

All needed ports (http; ssh, sogo etc.) are available - mmap says filtered.
httpd-admin and ssh are running. httpd-e-smith is not running.
With top I see that all processes are running.
I did not change anything. That's why I don't understand the problem …

I accessed many times the text based server-manager. All Accounts seem to run ok.

I checked "messages" and found an error on the mysql database.
- mysql.init: Error 1060  (this on several lines)

I checked ssh log at a time, when I tried to log in. It says:
- server listening
- Received signal 15: terminating

If I could print out the log files, it would be easier for me.

Hopes this helps,
Luca

Something strange happened. I installed the Printer Queue admin on my machine. In the server-manager I found no further informations. Then I tried thru a Webbrowser to access the admin; and it worked! I was able to log in to the Queue admin and analyze my printer.

But the rest is the same …

Thanks for your help
Luca

it's smeserver-print-monitor. But it is not so important.

httpd-e-smith is not running.

If that is so, it should be easy to find out why not.

cd /service/httpd-e-smith
sv d $PWD
./run

cd /service/httpd-e-smith
sv d .
./run


I typed these commands and get:
[Warn] worker http://127.0.0.1:20000/SOGo/dav is already in use by another worker

I saw this warning also in the messages...
