[Bug 374782] Re: Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04
tz i have solved the problem. the key is in SysAdminPrintingNew PrinterOther. by selecting Other, a URI request is made, and in it one enters bluetooth://MAC addr where MAC addr is the addr of my BT-200 which is connected to the HP 4 printer parallel port. the epiphany came when i started working with Ubuntu 9.10. but on a computer with 9.04, i made the requisite URI entry and the computer easily connect to the printer. it of course seems simple and somewhat obvious now, but this is how these things nearly always go. at any rate, i am now moving completely to the linux (Ubuntu) platform save for ACAD2000 (which i still will try to get to work under WINE. thanks again for all your time and support. -- Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04 https://bugs.launchpad.net/bugs/374782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 374782] Re: Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04
Also try rfcomm -a (may need sudo). Do you have the device in the /etc/bluetooth/rfcomm.conf file? If so could you include it (you can change the addersses if you are concerned). Also, try if it says bind yes, try bind no; (or just use # to comment out all the active lines), reboot, then from a command line as a normal user, type: rfcomm connect 0 btaddr have another console window open, and if the above says connected, do the ls -l /dev/rfcomm0 and see if the ownership and/or permissions have problems and/or try printing. Part of the problem might that you are binding the rfcomm device - telling it to listen, and the printer at the other end is also listening. When you do the open on /dev/rfcomm0, it might try to connect or might assume there was a connection. It won't work if both are listening and neither is starting up the connection. The rfcomm connect command above will initiate the connection to the printer. (you may also need the -r switch on rfcomm command line for the printer to work) -- Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04 https://bugs.launchpad.net/bugs/374782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 374782] Re: Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04
I remmed out all lines in /etc/bluetooth/ rfcomm.conf and ran rfcomm -a. it returned the MAC addr, channel and clean. the lines are 1)rfcomm0, 2)bind yes 3)device MAC 4)channel 1 (no # parentheses of course). rebooted computer and ran/get the following: ro...@rocky-desktop:~$ sudo rfcomm connect 0 00:08:f4:23:28:71 Connected /dev/rfcomm0 to 00:08:F4:23:28:71 on channel 1 Press CTRL-C for hangup in all cases, i continue to run test printer (with printer on) but msg still returns ' Idle - Unable to open device file /dev/rfcomm0: Permission denied' I set the URI to serial:/dev/rfcomm0 (CUPS GUI ?) believing this to be correct to set up a virtual com port for the printer which is what BlueSoleil does. I assume that this is correct? It is my understanding that we are trying to direct the printer to go out thru a virtual com port. from your suggested rfcomm connect cmd, it would seem that /dev/rfcomm0 is by-passed since everything is remmed in rfcomm.conf? and i tried the following with result: ro...@rocky-desktop:~$ sudo rfcomm -r connect 0 00:08:f4:23:28:71 Can't connect RFCOMM socket: Device or resource busy so does any of this produce possibilities? i see that BlueSoleil under XP sets up on COM port 4 if that means anything? mark -- Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04 https://bugs.launchpad.net/bugs/374782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It does say the fix is in jaunty-proposed. It would probably be a backport now, but you can use Software Sources to enable proposed and the update program might fix it. With the added udev rule, what is the full output line from ls /dev/rfcomm? Also did you try sudo ps ax | grep rfcomm?

going on? except for ls /dev/rfcomm0, i do not understand meaning of

/dev/rfcomm0 is NOT a file, it is a device node. That is what the c in crwx... means. When the bluetooth serial connects, rfcomm can CONNECT THE DEVICE TO THE NODE. It normally crates the file when it starts. Most things in /dev don't exist - check but I think /dev is mounted and populated by udev and other programs with nodes as the system finds devices.

Agree. Binaries have been uploaded to ubuntu-proposed with the merged fix from karmic.

Accepted udev into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This also affects many, if not every serial port profile device. In particular, GPS units no longer work for any program which uses rfcomm to create the connection. OBD2 sensors often use bluetooth, and generic serial ports (instead of a USB-to-Serial) The only things which might not use rfcomm are HID (mice, keyboards) and Audio devices. This should be marked to a reasonably high priority and included in some update to Jaunty instead of waiting for Karmic. -- Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04 https://bugs.launchpad.net/bugs/374782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This has already been fixed upstream (rfcomm were not in the dialout group) The following extra rule will fix it for you: KERNEL==rfcomm*, GROUP=dialout ** Changed in: udev (Ubuntu) Status: New = Fix Released -- Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04 https://bugs.launchpad.net/bugs/374782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
