Re: [Gumstix-users] ssh

Craig,

my mistake.  I forgot to use "ls -a". That's why I didn't see the directory and the "know_hosts" file.

Sorry, I suppose the 4 years break from Linux have been too long for my memory.

Rock. 

Craig,

there is a small misunderstanding. I did NOT reflash the Gumstix.
My Connex is still programmed with the kernel that Dave build for me.

When I installed the arm gcc tools I did not install it in a "gumstix-buildroot" directory.
Each time I was doing something that was on the wiki or suggested by the list I got
confused with the directories and decided to clean house and reinstall everything from
scratch in the "gumstix-buildroot" directory.

I can't follow the direction of the message because the directory, as mentionned, does 
not exist.

Sorry for the confusion.

Rock.
