I ran into a problem yesterday.

 

After a reboot of the Vu+Duo2 (OpenPli 4) Webif got inaccessible. Everything else, OScam, FTP, telnet etc. seems to running fine.

I have custom ports on everything, webif, telnet, ssh, ftp and is behind NAT.

 

The thing is that the box is placed on a remote location (an island in fact) so I have no physical access to it. Therefore Webif is essential. 

I have a PC in the local network of the box so I can reach it from inside if needed.  

 

 

I have tried the following without any success:

opkg update
opkg upgrade

root@vuduo2:~# opkg remove —force-depends enigma2-plugin-extensions-openwebif

I'm stuck, not sure how to proceed.

 

If you'd like to see logs I can pull them out for you, just tell me where.

 

Thanks in advance!

Difficult to say. OpenWebIf normally presents itself on port 80. If all other functions work perfectly on the given IP and ports you might consider 2 things:

 

1. Port 80 on router has been closed for outside access.

2. OpenWebIf is at fault..

 

In any case: opening up your STB without stringent protection is asking for trouble. At least use a VPN connection and strong passwords. STB's are not designed for internet access. They lack the necessary protection....

[SpliNT]

Yes, that's about the conclusion i drew myself. I doubt this is a port problem since I get the same results in the local network where the box is situated. 

I get no luck on neither the custom port or port 80. If OpenWebif is at fault, is there no way of rebuilding it from telnet? 

 

It is like its refusing connections. 

 

Is really a flash the only way?

[goldeneye]

The only thing you can do is simply visit the location and check the internet connection. Maybe the router needs a 'kick in the butt'. If you have remote access to the router you may want to check things first...

Best guess now (and it really is a guess/assumption) is that your box has been compromised. So yes.. Flashing is the best thing to do.. Set up a VPN connection to the box and secure the connection... As stated earlier, STB's are NOT designed to advertise themselves over the internet however convenient this might look... In fact, there is no need to unless one wants to engage in illegal activities...

If you can telnet into the box, type

netstat -lnp | grep :80

You should get this back:

tcp        0      0 :::80                   :::*                    LISTEN      503/enigma2

If not, then the webserver that is part of Enigma isn't running. As far as I can see there have not been any recent changes to the webif, git1332+3f47ff8 is the latest commit, three days ago.

[SpliNT]

Wanwizard: Seems like you're onto something here.

root@vuduo2:~# netstat -lnp | grep :80
tcp        0      0 :::8002                 :::*                    LISTEN      496/streamproxy
tcp        0      0 :::8003                 :::*                    LISTEN      496/streamproxy
root@vuduo2:~# 

Is there anyway to start the webserver from telnet?

[SpliNT]

I tried going to 192.168.x.x:8002 in the browser and I do get to a page with system info.

 

So.. the webserver seems to work..

[WanWizard]

The webserver component is a python plugin.

 

Can you stop enigma using the "init 4" command, and than start it manually using "/usr/bin/enigma2". It should that log it's output to the terminal. If you can capture that and see if you see any webif related messages?

 

When you're done you can start enigma again using "init 3".

 

edit: the other ports are serviced by a different component, so that doesn't say anything.

[SpliNT]

Done. Couldn't find any webif related messages. Pasted the output here in case I missed something.

[SpliNT]

Hmm. I can't seem to find config.py at that location, only config.pyo. I tried to open config.pyo but it didn't make me wiser. 

[WanWizard]

The problem is not in the code, but in the config somewhere.

 

I'd start by checking /etc/enigma2/settings, which is your main config file. The error suggests there is a config key "config.misc.prev_wakeup_time" which should be defined as an integer, but is in the config file as a float ("1448265935.02").

 

1448265935 is unixtime for Mon, 23 Nov 2015 08:05:35 GMT, not sure how a float value could be stored there. Wakeup time for EPG import perhaps?

Ah yes, that one. I've had it a few times as well. It IS an error in the config, but it's caused by a bug in enigma. For me it happens when I stop enigma before it has finished completely starting up. The simple workaround is to change the value to zero or to remove the key altogether. But the bug needs to be fixed. Apparently somewhere this value is written as float and read back as integer. I am not completely sure the above value is valid anyway, but it shouldn't crash.

[WanWizard]

Used here: https://github.com/O...rev_wakeup_time

 

Navigation uses it, and sets it to zero. Mytest checks if it's zero. It isn't used elsewhere in the Enigma2 repo, so I assume it's a plugin that sets it?

/etc/enigma2/settings

 

config.misc.prev_wakeup_time=0

 

Changing the value to zero did the trick! 

 

Thank you so much both you for the fast help! 

You saved me from a cold trip to an island in the Stockholm Archipelago.

Think of all the beautiful scenery you will miss on your trip...
