No web interface

Hammer · Post by **Hammer** » 13 Oct 2007, 11:41

The starting web page is gone.

By that I mean when surfing to http://bubba or using the external IP, I get "Internet Explorer cannot display the webpage".

Everything else works fine, including the itunes web page.

Have tried rebooting bubba, restarting ftd.

No bleeding luck.

Any ideas?

Can you reach the web-interface directly with http://bubba/web-admin?

If not, can you try to ping bubba from the commandline? My interest here is to see if your computer manages to solve the hostname "bubba" to an ip-adress.

No.

Even when using the IP no + "/web-admin" I get this:

Network Error (tcp_error)

A communication error occurred: "Connection refused"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

Does "normal" file access from within the windows filemanager work? Are you able to access your the home and storage shares from the network? Do you run any firewall on your computer?

Yes, I can browse to Bubba with wincmd/explorer and transfer files from the primary computer, no problems.

I can stream from bubba to a second computer (on the LAN).

I can access the iTunes applet and have it sing for me.

Might it have something to do with ports?

Hi Hammer,

Just to make sure that the web server is running, could you log in on Bubba and issue:

Code: Select all

ps ax | grep apache

and

Code: Select all

netstat -tl

and return the output.

Hi

the ps command only works properly when the correct switches are placed:

Code: Select all

ps auxw | grep apache2 | grep -v grep

if that gives nothing try (as root!):

Code: Select all

/etc/init.d/apache2 status

if it says something else than [running], try:

Code: Select all

/etc/init.d/apache2 restart

as your netstat is not listening to port 80, you may probably skip straight to that last command

if that does not work, you can test the apache2 config file:

Code: Select all

apache2ctl -t

Hammer,

Ubi is right in that apache, the webserver does not seem to run. Strange that a restart of bubba does not fix this.

What happens if you try the last two suggestions from Ubi?

Hammer · Post by **Hammer** » 18 Oct 2007, 13:16

First command gives nothing.

Second gives:
"Usage: /etc/init.d/apache2 start|stop|restart|reload|force-reload"

Third gives:
"Forcing reload of web server: Apache2 ... no pidfile found! not running?"

Fourth:
"Syntax OK"

Then I got creative and tried
"/etc/init.d/apache2 reload"
which gave me

"Reloading web server config...httpd not running, trying to start
done."

and while I were at it also the "force-reload" switch.

Here I stopped this mindless hacking and just typed in bubba in my browser, and alas, it works!

Anyone got any idea of why??

Thanks for your help guys!

Hi Hammer,

Nice to hear that you can access web-admin again.

It seems like apache somehow either did not start or crashed for some reason. Thats why when you issued "/etc/init.d/apache2 reload" it probably started.

The big question is why a restart of Bubba it self did not solve this. It should have been started at boot. So there is a big risk that when you restart bubba next time, apache wont run.

If that happens, please let us know.

Ok, now it has happened again.
I have restarted SSH, FTD and Apache2.
I can login to webmin and do everything, but when I go the downloads page the whole web interface freezes.

¤#%&"#¤%"¤&!!!!!

That felt better.

This started when I entered a torrent via my cell phone. (http://torrents.thepiratebay.org/385313 ... PB.torrent)

Here's a little output:

bubba:/home# ps ax | grep apache

13281 pts/0 S+ 0:00 grep apache

Why so many apache2 processes after this sequence??

Post by **tor** » 23 Oct 2007, 08:45

Hi Hammer,

The many apache processes are completely normal. Apache starts that many instances of the web server to be able to serve requests more efficient.

I think this is actually a general bug in FTD or its interaction with apache. On some torrents, or on some days, I see this exact behaviour. Maybe ftd is waiting for something, but not timing out properly. Often restarting both apache and ftd is the only thing to solve the freeze. Some days everything goes fine. I acknowledge that this inconsistency makes debugging a nightmare, but it is IMHO the single biggest bug in Bubba (Fortunately, a new version is in the works).

BTW1; restarting SSHd is really not useful here. It has nothing to do with this issue.

BTW2: please do not confuse web-admin with webmin (http://www.webmin.com/). They are quite different but both can exist on Bubba.

tor: ok, thanks, but got anything to say on the actual problem?

Ubi: Agree on the bug assessment and both your BTWs noted, thanks. I write those up to my infinitesmal knowledge of linux.

It doesn't matter how many times I restart ftd and apache2, it still hangs.
There is nothing in the torrents directory, can there be remnants of this infernal Dexter torrent somewhere else that clogs things up?
