Re: Linux and JMRI software.(SOLVED)
« on: October 08, 2011, 05:27:08 PM »
Hello,
      I have installed JMRI software into my home folder on a spare laptop.It is from outside the repositories so I recognize I have crossed a red line. :)
I would just like to inquire if anyone else has used this software successfully on a  PCLinuxOS setup.I didn't want to use another distro like others have as I prefer PCLinuxOS.
I am curious to know if the old fashioned serial ports are still supported with current kernels.The reason being that programs in JMRI keep highlighting "No ports found"  
Thanks.
trustytrev. :)

Since JRMI is written in JAVA you really haven't crossed any red line by using it.

Everything that I see suggests that they are still supported. Even if they were not supported JMRI is compatible with USB-to-Serial adapters

Did you do this
Give user-level application access to serial ports
chmod 666 /dev/ttyS0
chmod 666 /dev/ttyS1

from what I see they are by default set to 660

No not yet but I will give it a try.
That would need use as root does it not?
Thanks.

Looking at /dev in Krusader-root mode it shows as /dev/ttyUSB0 and shows as rw-
How do I get to display  user-level application access with numbers?

the /dev/usb0  is for your usb not the serial port.  you want /dev/ttys0 or ttys1  those are your serial ports.
I am sorry I don't understand your question here "How do I get to display  user-level application access with numbers?"

The /dev/usbo is the Merg usb module I am using.

I wondered why they don't show when I check hardware in PCC and DecoderPro or PanelPro announce "No ports found"

I was referring to how to display the current file permissions as numbers rather than rwx ie:7 or r=4  w=2 and x=1
to check the file permission settings before I change them.
Thanks.

Hello,
      I found out about file permissions. :)
I have done:
chmod 666 /dev/ttyS0
chmod 666 /dev/ttyS1
and chmod 666 /dev/ttyUSB0
I believe that covers all the ports in question.
But I am still getting "No ports found" when I start the JMRI software up.

Hello,
      I have had a response from the JMRI user forum.Can anyone advise please, if it is possible to make appropriate changes, and how to go about it.?

This is your problem. You need to have the right permissions to create the
lock file.

This is where things get to be a pain. It's an easy fix, usually. Add
yourself to the group that can write lock files, and you're all set.

The tricky bits being: what is the name of the group that can write lock
files?

Depends on your distribution. I know nothing of PCLinuxOS, so I can't speak
from direct experience. On Fedora, it's group 'uucp'. I think it's
something different on Ubuntu. It can usually be found by checking the
lock directory for the controlling group. Of course, where the lock
directory is varies from distro to distro as well.

Once you get this squared away and have added yourself to the right group,
log out and log back in again for the new group permissions to take effect.
Then re-run DecoderPro.

Open PCLinuxOS Control Center. Click System in the left panel and Manage users on system in the right panel. Highlight your username, then click the Edit button. Click the Groups tab in the popup window. Scroll down the list and put a checkmark next to uucp. Save all changes.

Hello,
      I did as suggested in the last post.It has progressed the issue with running jmri software but it still has problems.I will refer back to the jmri users forum and see what they say about the out put from the console.I am presuming the problems remaining are with the jmri software.As can be seen it has changed output since following the advice in the last post.

Hello,
      I have had success thanks to assistance here, the JMRI user grouphttp://groups.yahoo.com/group/jmriusers/and the MERG forumhttp://www.merg.org.uk/forum/viewtopic.php?f=69&t=1412My journey can be followed at the various forums.
I guess I can say JMRI software will work on PCLinuxOS.Linux does it again. :)
Thanks to all.
