OpenSUSE :: 11.3 Minicom Permission Denied With Usb Serial Adapter?
Jul 21, 2010
I have a usb serial adapter and was happily using minicom with it under openSUSE 11.2. I've upgraded to openSUSE 11.3 and I can only use minicom with this serial adapter as root. I had previously had problems writing to /var/lock under openSUSE 11.2 which I worked around by changing the minicom config to use /tmp as its lock file location.
Unfortunately my laptop doesn't have a built in serial port so I can't tell if its a general problem or something specific to the /dev/ttyUSB0 device. This is the output I get when I run minicom with my regular user account. I get the same output whether the lock file location is set to /tmp or /var/lock
Code:minicom usb0 Device /dev/ttyUSB0 lock failed: Permission denied. Before I started tinkering my user belonged to the following groups groups=16(dialout),33(video),100(users) I've since added 5(tty),14(uucp),21(console) but still no joy.
I am using a Prolific pl2303 USB<=>Serial adapter. dmesg reports everything seems ok when I plug it in (see below) but when I open the ttyUSB0 port in minicom, it is always offline and nothing works. Also, minicom reports:
[code]....
If I plug the adapter into a different machine (Windows) everything works fine. The serial port is setup correctly (9600-8-N-1) What can I do to get this working?

I am working on a embedded target board which runs on linux. The target board is connected to a linux machine through serial port. To bootup the target board, I run the minicom in the linux machine, boot the kernal of the target board through giving the boot command through the serial console (minicom). Now the question is when the target board boots up, it doesn't starts a shell. The rc scripts are getting executed. There are target specific applications getting started from the rc scripts. I appended & to the last launched application. Still I don't get shell prompt.
Minicom was running fine two days ago capturing data from a gage device via a serial cable. Yesterday, users of the data started complaining that they were not receiving any data.
The minicom status line reads offline. Is this part of the problem or is this normal (I never really noticed it before.) All settings on the gage device match the minicom settings.
I am running kubuntu 9.04. I have minicom, Gtkterm and Putty installed. minicom seems to be really good, but I am missing scroll back functionality on there. Either that or I'm a novice with it and don't know how to do it. Putty is a GREAT app. But what I'm finding is that after the terminal runs for a bit, the screen shows characters from the previous lines and goofs up the output. If I move the window, the gibirish disappears. gtkterm is adding several empty lines to any of the screen output.
I am hoping to be able to get an old serial-touchscreen to work with a usb/serial adapter. I had this touchscreen working some years ago on different hardware. I would like to hook it to the machine I am setting up as a multimedia host with mythtv among other things.
Following the instructions I left behind when I got this to work way back when does not work. See [URL] ....
This info is a work around to get the xserver to see the touchscreen. [URL] ....
I do know that the touchscreen works as I am able to get garbage on the screen as in the first part of my howto. But I have not had any success getting xorg to see it. I wish I had posted a copy of the xorg.conf at the time, but......
There is an issue with the current xserver in testing that I am hoping the next update (in unstable) will fix when it gets pushed to testing. That is that Code: Select all# X -configure fails with a segfault. So I am not able to generate the xorg.conf needed to get it to work. I was going to post a bugreport, that is when I found out there is an update in unstable, so I am waiting for it to get pushed at the moment.
Anyway I am hoping that I can link /dev/ttyUSB0 to /dev/tty0 and get it to work. I would like some kind of guess as to my chances of success before I go to all the work of getting the monitor hooked to the host.
I noticed when running "ps -ef" that there are a bunch of processes listed with brackets. ie "[process]". Some of them appear to be daemons and others look more like kernel modules? I haven't found a program directly associated with them and was hoping somebody could clarify this for me?
Also, if I run a search of the file system with sudo or as root, there is a directory in my home that returns a permission denied. I understand permissions but shouldn't operations as root be able to do/access anything on the system?
After an upgrade to opensuse 11.3 from 11.2 it turns out that cron uses pam for authentication. Now I have one user 'mythtv' which does not have a login and is not part of the 'users' group. This user is being denied access (permission denied messages in /var/log/messages from crond).
Now, I have been experimenting with the /etc/pam.d/crond config file. I wanted to use the pam_listfile module to grant access to this specific user without authentication. That however didn't work and I have now narrowed down the problem even more.
I am trying to connect to my web host via ssh. I can do this on Windows using Putty without issue. However, if I run this on Linux, I receive a "permission denied" when I am prompted for my login and password. It's obviously making some type of connection, otherwise it wouldn't be prompting me for authentication.I initially thought this was a firewall issue.I opened up port 22 and I even tried disabling the firewall altogether.However, I still received this error.
i have client and server PCs, both with openSuse 11.2.
on the server side, i have mounted HD partition to /vmshare dir. relevant line in /etc/fstab reads:
Code: /dev/disk/by-id/ata-WDC_WD3200AAJS-07B4A0_WD-WCAT16493946-part2 /vmshare reiserfs user,acl 1 2 i want to export /vmshare dir via nfs. i have configured it through yast and resulting line in /etc/exports reads: Code: /vmshare *(rw,root_squash,sync,no_subtree_check,crossmnt) the permissions for this directory is drwxrwxr-x root vmshare.
i can successfully mount the exported dir on client side, i can move between directories and list contents, but i can't write into it (not even as a root). on the server side, i can write to the directory only as root. the vmshare group is created on both machines with same gid as well as all users have same uids. firewalls are down.y.
I am trying to use VirtualBox which worked just a week ago (I haven't changed anything with it) but now it fails. When I try to start it (from the command line) with /usr/bin/VirtualBox, as a regular user, it fails.
I'm configuring Amanda Enterprise on an OpenSuSE 11.3 system, and everything but the scheduled backups are running. I decided to try and fix it tonight, but I'm pretty fed up by now.
So here's the background:
The application creates an account on the box named "amandabackup" and adds it to the 'video' and 'disk' groups.
It generates cron jobs in /etc/zmanda/zmc_aee/crontab, which is configured as the location of the crontab file for the amandabackup user.
The crontab is owned by amandabackup:disk with a mask of 644.
So I played around with it a little bit; I ran the backup task manually as amandabackup, which worked fine.
I then tried adding the following to the crontab:
And touched amandacron.log, then made sure it was owned by amandabackup with a mask of 644 (i also tried /etc/amanda/amandacron.log, which is a directory the account stores backup session configs in, so I know it can write to it properly). The file is never updated. I tried adding amandabackup to different groups (it's currently been added to the "Users" group), with no success. I tried a symlink to the crontab file in /etc/cron.d to see if that would make a difference, but it didn't.
At this point, I went online and tried some more stuff I found:
I checked /var/log/mail/amandabackup - everything *but* cron jobs were reporting to it.
I verified cron was running with both "ps -ef | grep cron" and "rccron status"
I ensured /var/spool/cron/tabs/amandabackup existed, showed the proper entries, and was set to 644. (this one's the important bit)I checked /var/log/messages, and every minute on the dot I see: <timestamp> /usr/sbin/cron[PID]: Permission Denied
I ensured there was no /etc/cron.allow, and that /etc/cron.deny did not contain amandabackup.
I tried making an /etc/cron.allow, adding amandabackup, and restarting the cron daemon, but this did nothing.
I don't think I've forgotten anything, but my attempts have been getting progressively more feverish, so I'm not positive. Is there some annoying YAST cron panel I'm not seeing? Is there some way of getting more verbose logging out of the cron daemon than just "permission denied"? Is there some draconian rule about crontabs only working based on some otherwise-arbitrary account setting?
11.3 in use with KDE. When I plug in an USB stick or my HTC phone into the USB connector the device is recognised but can't be opened in dolphin. This is the error message:
Code: org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freedesktop.hal.storage.mount-removable auth_admin_keep_always <-- (action, result) but the device is shown in dolphin as a removable device and

I'm running openSUSE 11.4 (gnome) and I'm trying to transfer files to my windows partition and it says that I don't have the permission to do so. How do I gain access to it?
As root I get the following result: ngssuse:~ # traceroute -nI 10.200.123.45
Note: the -i and -I options were exchangedfor compability with LBL traceroute Use -I for ICMP, and -i <ifname> to specify the interface name unable to create ICMP send socket: Permission denied. Is this a bug?
I did some reading on Openvpn and am following some instructions I found @ Install & Configure OpenVPN SSL VPN in SUSE & openSUSE Linux | SUSE & openSUSE
I keep getting the same error message when I run the . ./vars command "NOTE: If you run ./clean-all, I will be doing a rm -rf on /etc/openvpn/easy-rsa/2.0/keys"
But when I run ../vars I get "Bash: ../vars: Permission denied"
And I added umask 022 to the user login script problem I have: I login with user and password that exists as a local user on my suse machine. I can read and download from my homedirectory, but I cannot upload with filezilla. Then I get the error: 550 permission denied critical file transfer error
Code: # traceroute -I 69.12.32.2 Note: the -i and -I options were exchangedfor compability with LBL traceroute Use -I for ICMP, and -i <ifname> to specify the interface name unable to create ICMP send socket: Permission denied Note that the command was done as root. This worked in 11.3.
And yes, it works without the "-I". But it should work with the "-I". One shouldn't have to boot into Windows, just to run "tracert" there.
i need a usb to rs-232 converter to get into the console port i have an aten uc-232a converter and i have downloaded a .gz file called uplcom.4freebsd.gz i have unpacked it but i do not know what to do from here could some one please help i need to do some practice for the external icnd 2 exam and i have left it to the last minute as per usual.
My program tries to open serial port on Fedora 12, and shows "Access denied" on Open Port operation. The same program runs successfully with root rights. What can I do to get COM port access as regular user?
I am using a Sealink PN 2202 USB serial adapter on a linux box (Ubuntu 10.4) running kernel 2.6.32-28-generic. I have written a perl script to simply log the incoming RS232 data (9600 8N2) and it works fine when I start it from a bash shell: perl /home/pk/PerlCode/RS232_D4_v11.pl
However, I need the computer to boot and start logging after a POR. If I try to use Startup Manager to execute my script everything seems ok but I randomly loose about 20% of the incoming RS232 data. In Startup Manager I use the command gnome-terminal --title="D4 RS232 Log" --execute bash -c "perl /home/pk/PerlCode/RS232_D4_v11.pl"
If I close the automatically-started script and restart it from a bash shell, I again will randomly loose about 20% of the incoming RS232 data. It almost seems like I have screwed up the driver by using the Startup Manager. The only way I can get reliable logging again is to remove the script from Startup Manager, then restart the computer and manually launch the perl script. I was thinking that maybe the order in which the driver was loaded and perl script started might be an issue. So I tried a bash script that sleeps for 15seconds, then starts the perl script. Again, I loose random pieces of incoming data when this is initiated by Startup Manager.

I though it may have something to do with su vs my ownership of files. If I do a sudo chmod 777 /dev/ttyUSB* then ls -al /dev/ttyUSB* crwxrwxrwx 1 root dialout 188, 0 2011-03-08 09:56 /dev/ttyUSB0 crwxrwxrwx 1 root dialout 188, 1 2011-03-08 09:56 /dev/ttyUSB1

Im a very basic Linux/ Centos user. I have Putty installed and a USB to serial adapter. All settings seem to be right as far as speed, etc, but I'm not sure how to list the device to open for the program. The default location it gives is "/dev/ttyS0" Trying to find where the USB is located using the "/sbin/lsusb" command gives me-
Bus 001 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 004 Device 002: ID 0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303] Bus 004 Device 001: ID 0000:0000
So I think this means that it is on bus 4 correct? So how do I list this for putty to open the device.
I picked up as Dynex usb2serial converter to use with my cisco router/switch. The dongle works fine if plugged into a windows box & puTTy, but I cannot get it to work with Fedora 14. When I try to use cute, mini or command line it tells me it cannot open the connection. Here is the output from lsusb and dmesg. susb output:
