Hi,

I'm trying to sync my Palm in Slackware 10.2. I "think" I have most issues worked out. (I've installed Pilot-Link and JPilot.) The hang up seems to be on my permissions. When I try to connect through ttyUSB0, I get a message in console "Permission Denied." I tried logging in as root, chmod +x /dev/ttyUSB0, then opening another console tab and starting JPilot...I still get "Permission Denied."

Thanks,
_Joe

+x = execute
+w = write
+r = read

When I use +r, I get "No such file or directory." But, when I press the "Sync" button on my palm pilot, I receive the following output:

I admit I'm lost here. In other distros, I simply used /dev/ttyUSB0 or /dev/ttyUSB1 or /dev/ttyUSBwhatever and everything worked just fine. I've tried every possible combo I can think of with this, and I still cannot get this to link with either JPilot or KPilot.

As root run chmod 666 /dev/ttyUSB0 and/or ttyUSB1. If your using a 2.6 kernel with udev you should make a rule to do this during detection. And, if you need, I could post mine for you to use as a model.

Hi dracolich!

That absolutely did it. I can sync now.

Thank you!

Hi gbonhevi!

I didn't know about +r and +w. I'll make a note of it.

Thanks,

In case anyone ends here, the letters are actually a "wrap" for the numbers, they do the same thing.
1 = +x = execute
2 = +w = write
4 = +r = read

3 = 1 + 2 = +xw = execute + write
5 = 1 + 4 = +xr = execute + read
6 = 4 + 2 = +wr = write + read
7 = 1 + 2 + 4 = +xwr = execute + write + read

I guess you get the point

And if you are not on the subjects of permission, you may wonder why a 6 three times?
The first number belongs to the user owning the file, the second to the group the file belongs to, and the third to other users.
So with chmod 666 /dev/ttyUSB0 you gave that file read and write permissions to everyone, the owner, the group and other users.

What you did, was to give that file write and read permissions which is what the program needs to be able to sync with your Palm.
