luup.inet.wget "http://openluup.home.lan/cgi-bin/cmh/backup.sh" not working

Hi guys,

I have a problem with my scene that runs a backup. It contains only the following luup code:

luup.inet.wget “http://openluup.home.lan/cgi-bin/cmh/backup.sh”

This is what I see in the log of openluup:

2018-08-01 11:08:39.221 openLuup.server:: POST /data_request?id=lr_ALTUI_LuaRunHandler HTTP/1.1 tcp{client}: 0x215ba08
2018-08-01 11:08:39.221 luup_log:0: ALTUI: runLua(luup.inet.wget “http://openluup.home.lan/cgi-bin/cmh/backup.sh”)
2018-08-01 11:08:39.223 openLuup.server:: WGET status: closed, request: http://openluup.home.lan/cgi-bin/cmh/backup.sh
2018-08-01 11:08:39.223 luup_log:0: ALTUI: Evaluation of lua code returned: nil
2018-08-01 11:08:39.224 openLuup.server:: request completed (8 bytes, 1 chunks, 2 ms) tcp{client}: 0x215ba08
2018-08-01 11:08:39.224 openLuup.server:: socket closed: closed tcp{client}: 0x215ba08
2018-08-01 11:08:40.229 openLuup.server:: closing client connection: tcp{client}: 0x1955098

Nothing more.

When I just put the URL in my browser it works fine. Also doing a wget via command line in openluup works fine.

I don’t get it. Can you help me out?

Thanks.

ps. I’m on openluup version 18.3.23

Update

Running it from Vera doesn’t work either, so maybe it’s a network issue. I see this in the log Vera:

I also tried the URL with the IP address in it, didn’t work either.

Try using port 3480?

luup.inet.wget "http://openluup.home.lan:3480/cgi-bin/cmh/backup.sh"

That seems to work. Although I get a timeout in the test lua. Is that expected in this case?

Any idea why it doesn’t work without the port?

Good!

Possible, since the compression of the backup file might take a little while. But I’m surprised. Is this true for both openLuup and Vera, or just one of them?

Any idea why it doesn't work without the port?

Why would it? Vera and openLuup use port 3480 for their server requests. Sending it somewhere else and whatever is listening won’t understand it. Vera has recently (or are about to) switched off direct access to that port, so, in fact, you should go through port 80 using

luup.inet.wget "http://openluup.home.lan/port_3480/cgi-bin/cmh/backup.sh"

which the lighttp server redirects. For openLuup, you must use the actual port, since it runs its own HTTP server, which is nothing to do with the Apache one, or whatever your system is normally using.

Ok, thanks AK!

I think it used to work, but that’s probably because of changes in my nginx setup.
