Adding users to more than one group?

arashi256 · 01-22-2008, 01:06 PM

Possible under FC8/GNOME? I think I need to do this to allow the PalmOS connectivity to work with the daemon controls the /dev/USB0 (or whatever) that controls the directory permissions for USB connectivity at /dev/USB0 and /dev/USB1 for syncing my Palm TX PDA, which seems to belong to the group "uucp" (whatever that is).

Any advice welcome.

Yes, of course it's possible. Here. for example, is my output of the id command
teddy@toshiba64 ~$ id
uid=1000(teddy) gid=1000(teddy) groups=92(audio),93(optical),1000(teddy)

You can do it either when creating the user, or later, by using the usermod command.

Natilous · 01-22-2008, 02:24 PM

in debian distros in /etc/group you can add users to any groups available.
I think on Fedora like this .
#vim /etc/group ({or other editors})

good Luck !

The proper way under Linux to edit groups is by issuing the command "vigr"

Code:

mingdao@silas:~$ man vigr
VIPW(8)                                                                                                                                                                 VIPW(8)

NAME
       vipw, vigr - edit the password, group, shadow-password, or shadow-group file.

SYNOPSIS
       vipw [-s]
       vigr [-s]

DESCRIPTION
       vipw  and  vigr  will  edit  the  files  /etc/passwd and /etc/group, respectively.  With the -s flag, they will edit the shadow versions of those files, /etc/shadow and
       /etc/gshadow, respectively.  The programs will set the appropriate locks to prevent file corruption.

       When looking for an editor, the programs will first try the environment variable VISUAL, then the environment variable EDITOR, and finally the default editor, vi.

SEE ALSO
       group(5), passwd(5), shadow(5)

                                                                                  26 Sep 1997                                                                           VIPW(8)

i have always used usermod -G for adding users to groups.

arashi256 · 01-23-2008, 03:32 AM

Okay, thanks - I'll try that and see if it helps with my Palm TX any. Good to know how to do it anyway.

If you are successful getting a Palm T|X to work with Linux, I'd like to know. I have one and have followed every bit of advice on the world wide web and it has never worked with kpilot or j-pilot. My kernel recognizes it as an USB device:

Code:

root@silas:~# tail -f /var/log/messages
Jan 23 20:02:39 silas -- MARK --
Jan 23 20:22:39 silas -- MARK --
Jan 23 20:42:39 silas -- MARK --
Jan 23 21:02:39 silas -- MARK --
Jan 23 21:21:20 silas kernel: usb 4-2: new full speed USB device using uhci_hcd and address 2
Jan 23 21:21:20 silas kernel: usb 4-2: configuration #1 chosen from 1 choice

but that's as far as it goes. None of the other programs that should work have ever seen or connected with it. For the time I invested recompiling kernels and compiling software, I could have built a dedicated Windows boxen and used the software written for it instead.

arashi256 · 01-23-2008, 07:43 AM

Yup, thats about as far as I've got with my Palm TX under Linux right now. By monitoring the dev directory, it adds ttyUSB0 and ttyUSB1 when plugging in the Palm TX via the USB cable, but will not recognise a sync. If I manage to get it working, I'll post back - its an ongoing thing at the moment.

Bruce Hill · 01-23-2008, 09:02 AM

In my recent custom kernel I didn't compile support for USB-SERIAL. So I recompiled a kernel, and now have this:

Code:

mingdao@silas:~$ lsmod | grep usbserial
usbserial              25960  1 visor

The output from the kernel is different, also:

Code:

root@silas:~# tail -f /var/log/messages
Jan 23 22:36:37 silas kernel: usb 4-2: new full speed USB device using uhci_hcd and address 3
Jan 23 22:36:37 silas kernel: usb 4-2: configuration #1 chosen from 1 choice
Jan 23 22:36:37 silas kernel: visor 4-2:1.0: Handspring Visor / Palm OS converter detected
Jan 23 22:36:37 silas kernel: usb 4-2: Handspring Visor / Palm OS converter now attached to ttyUSB0
Jan 23 22:36:37 silas kernel: usb 4-2: Handspring Visor / Palm OS converter now attached to ttyUSB1

but I still can't get it working with J-Pilot of KPilot. This is the other output:

Code:

mingdao@silas:~$ pilot-xfer -p ttyUSB0 -C
   Unable to bind to port: ttyUSB0
   Please use --help for more information

mingdao@silas:~$ sudo -i
root@silas:~# pilot-xfer -p ttyUSB0 -C
   Unable to bind to port: ttyUSB0
   Please use --help for more information

Didn't work as user or root.

I also added my normal user, and root, to both tty and uucp groups, which didn't change anything.

And for the /dev entries:

Code:

mingdao@silas:~$ ls -l /dev/tts/USB0
crw-rw---- 1 root uucp 188, 0 2008-01-23 22:55 /dev/tts/USB0
mingdao@silas:~$ ls -l /dev/ttyUSB0
lrwxrwxrwx 1 root root 8 2008-01-23 22:55 /dev/ttyUSB0 -> tts/USB0

I've not come across a single <Linux> Google hit that helped ...

Bruce Hill · 01-23-2008, 09:14 AM

Furthermore ...

Code:

root@silas:~# ln -s /dev/ttyUSB1 /dev/pilot
root@silas:~# pilot-xfer -p ttyUSB1 -C
   Unable to bind to port: ttyUSB1
   Please use --help for more information

root@silas:~# pilot-xfer -p ttyUSB0 -C
   Unable to bind to port: ttyUSB0
   Please use --help for more information

root@silas:~# pilot-xfer -p ttyUSB0 -C
   Unable to bind to port: ttyUSB0
   Please use --help for more information

root@silas:~# pilot-xfer -p ttyUSB1 -C

   Listening for incoming connection on ttyUSB1... connected!

   Thank you for using pilot-link.

root@silas:~#

but I'm clueless what to do past that point. KPilot and J-Pilot still don't work, or report that access is denied to /dev/ttyUSB0

Bruce Hill · 01-23-2008, 09:22 AM

Well, reading those "man pages" is paying off ...

Code:

mingdao@silas:~$ man pilot-xfer
OPTIONS
   pilot-xfer options
                               -a, --archive
                               <dir>

       Archives files which have been removed from the Palm to lt;dir> instead of just deleting (unlinking) them.

                               -b, --backup
                               <dir>

So I pressed the hotsync button on the Palm, and issued and got this:

Code:

root@silas:~# pilot-xfer -p ttyUSB1 -b /home/mingdao/palm

   Listening for incoming connection on ttyUSB1... connected!

It's still backing up the Palm ... don't know what else to tell you. I should have issued the command as a normal user, because the files under my home directory are owned by root atm. Though a simple "chown -R mingdao.users /home/mingdao/palm" will solve that issue.

In the kernel you need USB_SERIAL, as well as the normal UHCI or OHCI support, USB-HID, etc.

You need to symlink /dev/ttyUSB1 to /dev/pilot, then issue those commands.

Maybe someone with more experience will come along and bail us out.

arashi256 · 01-23-2008, 09:49 AM

Some of that stuff is double-dutch to me at the moment, but I'll check your posts carefully tonight when I have more time to do some research too. I really hope Fedora has that USB_SERIAL thing included, as I'm in no shape to recompile my kernel at the moment.

arashi256 · 01-26-2008, 10:17 AM

Gnome-Pilot now seems to work with the USB cable after installing the latest kernel update. Works a charm. Perhaps I didn't have USB_SERIAL support or whatever on by default in the last one.
