[webif] Web Interface 1.2.x

hairy_mutley · Feb 12, 2016

OK, that confirms it. Just upgraded tunefix, it took about 10 seconds for the Internal Server Error box to come up. For approximately the last 7 days, every single upgrade, irrespective of what package it was (several have been webif, including 1.2.8-2 to 1.2.8-3 this morning), causes the same problem. It appears that the time it takes for the box comes up probably relates to the time it takes to perform the upgrade, long for a webif update, short for most others.
Once the box has come up, the HDR keeps working normally, but the browser is unable to connect to the webif. The webif is only restore by a reboot.

Hate to moan about the webif... the package page is definitely a lot quicker; it just seems to have brought this quirk with it!

Unfortunately I can't replicate this on my setup. Is there anything in your webif-error.log (command line, cat /tmp/webif-error.log) when this happens?

Unfortunately the log file is empty

This is a bit vague. What exactly does "unable to connect" mean? Is the server still running?
"service" or "ps ax" at a command prompt might tell us more.

af123 · Feb 12, 2016

Does this happen if you add or remove a package too? bash is a good one to test with as it's small and stand-alone..

What he means is

but the browser is unable to connect to the webif. The webif is only restore by a reboot.

Which is exactly what I get. There is one entry in my webif.log which is "2016-02-12 07:35:54: (log.c.194) server started" Which is when I rebooted after doing an update of tunefix and not being able to connect the browser on my PC to the Web I/F on the T2 without a reboot. Just get a 404 error on the browser until reboot.

Trev · Feb 12, 2016

Couldn't find bash. but just updated to tunefix x.x.x-9 and it's bloody locked up yet again. Back soon. Off to reboot.

EDIT. Installed bash. Server error. 404 on WI. Off to reboot yet again. :sigh.

I'm with hairy on this one. I think it started a few days ago when I had three upgrades. IIRC they were web i/f, lightpd, and tunefix

MymsMan · Feb 12, 2016

It works for me so unable to contribute diagnostics

af123 · Feb 12, 2016

404 error? Sounds like the web interface is still running then...

af123 · Feb 12, 2016

When you get that error, what's in the top/address bar of your browser?

Brian · Feb 12, 2016

I am also having this problem when updating packages. After getting the server error, I have used Telnet to run the 'service' command, which shows that lighttpd is no longer running. The command 'service start lighttpd' will then allow the web interface to work again without rebooting the box.

Trev · Feb 12, 2016

No. That's my interpretation.
It says something along the lines of Web page is unavailable. I'll test it now. Bash uninstalled with no error.

Trev · Feb 12, 2016

Right then. Re installed bash. Got the internal server error. Address bar at the time (still displaying WI) =http://foxt2/pkg/#1. With the package management popup still present.
Closed that, still the same after it had gone.
Refresh page. Chrome error= "This webpage is not available". Address bar is still the same as above.
From what Brian says, it seems that it is lighttpd that's causing the problem somehow. Have you still got the previous version to try?
Off to reboot.

Brian · Feb 12, 2016

af123, is there anything useful in this webif log?

"service" or "ps ax" at a command prompt might tell us more.

That is what Firefox said, in large letters across the middle of the page.
The address bar just shows "http://humax/" as it normally would for accessing my T2.
I haven't seen a 404 reported at any time.

Code:

Unable to connect

Firefox can't establish a connection to the server at humax.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer's network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

while all is running normally

Code:

I am with Brian, lighttpd has stopped, starting it has restored the webif without the need to reboot.

hairy_mutley · Feb 12, 2016

Confirming what Trev tried
Uninstalled bash with no problem... all keeps working.
Installed bash again, webif gone, but I am able to restore by starting the lighttpd service.

Still nothing in /tmp/webif-error.log

Brian · Feb 12, 2016

It seems that installing, or upgrading packages is causing lighttpd to stop running.

I'm seeing all these lines, with the exception of the "cgi died" one, and my server stays up.
Why is it apparently trying shut things twice I wonder?

Nor have I explicitly. I was wrongly interpreting a 'page not available' as a 404 error

But only after the recent update.
