[SailfishDevel] Sailfish Emulator on Lubuntu: SSH not working: Victoria in Excelsis!!!!

Hi Thomas

Thanks for your advice

I was aware of the "Agent admitted failure to sign .." know issue, but  
had not tried the SSH_AUTH_SOCK= workaround, as my error message is  
different.

However in the meantime I upgraded my Lubuntu installation to 13.04.  
After the upgrade, I got the Agent error AND the "Permission denied  
(publickey)" when trying to ssh to the MERSDK.

chris at LubuntuVM:~$ ssh -p 2222 -i ~/.ssh/mer-qt-creator-rsa  
root at localhostAgent admitted failure to sign using the key.
Permission denied (publickey).

--> applying fix from known issues:
chris at LubuntuVM:~$ export SSH_AUTH_SOCK=
chris at LubuntuVM:~$ ssh -p 2222 -i ~/.ssh/mer-qt-creator-rsa root at localhost
Last login: Sat Apr 27 16:10:26 2013
[root at SailfishSDK ~]#


As we see above the SSH_AUTH_SOCK= fixes things for the MERSDK.

Trying the same for the Emulator:
chris at LubuntuVM:~$ ssh -p 2223 -i ~/.ssh/mer-qt-creator-rsa root at localhost
Permission denied (publickey).
chris at LubuntuVM:~$ export SSH_AUTH_SOCK=
chris at LubuntuVM:~$ ssh -p 2223 -i ~/.ssh/mer-qt-creator-rsa root at localhost
Permission denied (publickey).
chris at LubuntuVM:~$

did not fix things for the Emulator.

After a lot of playing around I concluded that the problem is that  
Emulator (should that not be an Ostrichator on Lubuntu?) was not  
mounting its shared folders, while the MerSdk clearly was. In some  
ways i had hinted at this in my original post at the start of this  
thread.

So I tried this in the Emulator:

mount -t vboxsf ssh /etc/ssh/authorised _keys/

And Voila! I can now SSH in from the host Lubuntu as root and nemo.

So next I ventured into the dark world of fstab; adding an entry to automount:
cd /etc
echo ssh /etc/ssh/authorized_keys vboxsf defaults 0 0 >> fstab

After a restart, the shared drive is now auto mounted, and I can ssh in.

Interestingly (in a nerdy sort of way), after doing this the Emulator  
seems to keep its vertical shape. Previously it started wider, was  
briefly vertical, then switched quickly back to the horizontal wide  
shape. (This is circumstantial evidence at the moment, after one  
restart ...)

Most importantly, having ensured that the shared folder automounts, I  
can now build and run the mediagallery example without error: This was  
the original objective of the Lubuntu test installation.

So the question is: Why does:
1) the MerSdk on Lubuntu mount its shared folders no problem, but the  
Emulator on Lubuntu not automount, and needs tweaking as described  
above?
2) the MerSdk and the Emulator on OSX mount their share folders no problem ...

Grüsse

Chris
