irserver Segmentation fault - maybe me as confused

[nodepeeker]

Hi,

Device has IP 10.0.1.9
IRtrans (ethernet only) is working fine as I used my XP box to learn codes and save remote commands etc. It just won't work via Linux box.

so I installed latest software from website, all went fine.

I decided to use irclient, thinking my irtrans ethernet would just need the client software, so I typed:
./irclient 10.0.1.9
IRTrans ASCII Client Version 6.01.01
1 - Send
2 - Learn
3 - Status
99 - Exit
Select command 3
Getting Device Status ...This operation is only supported using the irserver
1 - Send
2 - Learn
3 - Status
99 - Exit
Select command 99

OK maybe I do need the irserver running on the Linux box.

As the hardware is not physically attached to the Linux box I PRESUMED as the documentation doesn't make clear, that device is the IP address of the hardware?

So I typed:
./irserver 10.0.1.9
IRServer Version 6.02.07

ANy Ideas? Pointers? etc?

Learning of codes has to be done through the irserver. That means the irserver needs to be running and the irclient connects to the irserver.

If the irserver crashes on startup there might be an illegal .rem file in the remotes folder or the server cannot access the remotes folder.

Please note that the irserver needs to be run as superuser (root).

You can also learn the ir codes using the Windows SW and simply copy them onto your LINUX box.

Hi, yes, learning codes is not the issue, have learned those.

Have removed MY .rem files from the remotes dirtectory incase they are corrupt.

I am logged an as root (always am)

Should the remotes folder have sticky set? Surely not the problem.

Just want to send commands to the irtrans (10.0.1.9)

OK, so using your "maybe bad remote" clue:

So I removed the next one that would be read
-rw-r--r-- 1 cupsys users 1494 2009-02-14 17:31 kathrein-ufs.rem

and bingo.

So anyone else getting this in future.
1) turn up the debugging
/usr/local/irtrans/irserver -timestamp -loglevel 4 10.0.1.9

2) Look for last thing it did ok, and remove the next item in the remotes folder.

Cheers

[IRTrans]

Thank you for the info !

We will check why the Kathrein .rem file crashes the server - that should not happen because it is one of our supplied remotes ...

IRTrans

[IRTrans]

Hmm, looks like you did not fully install the software.

You have an irserver version 6.01.15 while the latest download contains 6.02.07. Using that version nothing crashes on my test system.

IRTrans

[nodepeeker]

OK, just so you know, just removed the software, downloaded your latest, installed it and got:

so katy is the Bitch here rm her

[IRTrans]

Thank you for the info - that is really strange as it is working on our machine ...

Anyway, we will check that.

I have the same problem, it seems to have to do with stack trashing, which is detected on recent Ubuntu machines:

FYI: #define VERSION "6.02.07"

Solution: change line 2677 to something like

char cm[100],par[1000];

[IRTrans]

Thanks a lot for the info

You are absolutely right - we have already changed that and we will put a new version on our website shortly.
