Slackware :: Error - Cannot Open /dev/ttyACM0: Permission Denied
Aug 7, 2010
I installed wvdial on my Satellite Toshiba laptop. All works well but I have to use the <wvdial> command as root. If I try to use it as a user i get an error message Cannot open /dev/ttyACM0: Permission denied So Im just wondering; is it ok to use wvdial as root?
this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.
Error in console:
libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied. libusb requires write access to USB device nodes.
I have tried several things to attempt to fix my sudoers file however it is still coming up with errors. The error says
the sudoers configuration file is set to the default as I have ran a dpkg on it, have also uninstalled and reinstalled it, and went over the configuration file ensuring it looked like the defaults I had seen online.
I'm getting error from KVM when i try to create new machine. I have install group Virtualization. From gui virtual-manager (after being asked for root passwd) tried to create new machine. When pressed on 'Finish' got this 'Permission denied' error: Code: Unable to complete install '<class 'libvirt.libvirtError'> internal error Process exited while reading console log output: char device redirected to /dev/pts/3 qemu: could not open disk image /sonik_data/software_archive/CentOS-5.5-x86_64-netinstall.iso: Permission denied

It's running as a root, what permissions we are talking about here? I'm running F14, kernel 126.96.36.199-72.fc14.x86_64, libvirtd 0.8.3
when I try to su, with the right password I know it is because I have reset it with a sudo, it says su: incorrect password. Looking at /var/log/messages I see su: Unable to open admin password file: Permission denied. This must mean that the file has incorrect permissions and or owner/group. I am wondering if anyone knew where the file was located and the correct permissions/owner/group.
I do a "clean" root-only install; i.e., the only partitions that are formatted are the root and usr partition leaving the others untouched (so I don't have to restore the entire thing every time or fiddle with updating). That leaves almost everything in place with only a few edits and additions to make to get back in business; smart and dumb and the same time, sigh.
The partitions look like this for what it's worth:
Anyway, my web server comes up just fine and other applications work as expected except for Bugzilla and I can't remember what the heck it is I have to do to get it going again. I add a file, httpd-bugzilla.conf in the extra directory and include it at the end of httpd.conf:
In the above, /var/www/htdocs/bugzilla is not a symbolic link, Bugzilla is actually installed there (and has worked just fine for a long, long time). And, yeah, I know I'm not really supposed to do that but there it is.
I also run checksetup.pl which completes cleanly (it also sets permission masks and group) and double-check that localconfig looks like it ought to.
I just isntalled LAMP using tasksel and have a problem. Whenever I try to access a page (aside from phpmyadmin, that works well), I get this error... Code: Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0 Fatal error: Unknown: Failed opening required '/var/www/index.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0
I have restarted the computer, restarted apache, etc and still nothing. When I first installed, phpmyadmin was inaccessible, so I ran some command in terminal which apparently created a symlink between phpmyadmin in the user/share dir to the /var/www dir, and curious if this is the problem. I have no clue how to remove this symlink if this is the case, and have phpmyadmin working now due to install using sudo apt-get install phpmyadmin.
I was able to get the a2ensite command to enable a virtual site because it says "Site xxxxx.com already enabled" when I run the command. My problem now is that even though a site is enabled it says this: Code: /etc/init.d/apache2 restart * Restarting web server apache2

I am having problems gaining access to the BackupPC admin web page. The error:

Why is this occuring, is there anyway of getting around this? I just cant remember originally on my old system how I set this up.
I have a shared directory on another machine but I can't get it to mount. The permission denied doesn't say where/which permission is denied. Is it on the remote on on the local machine? The remote has sharing enabled for the shareddocs directory and after I have mkdir'ed the local mount point I open it's permissions too.
The verbose response from mount.cfis looks like this:
mount.cifs kernel mount options: unc=//192.168.1.102shareddocs,domain=WORKGROUP,ver=1,rw ,username=clive,,,,,,,,,,,ip=192.168.1.102,pass=** ****** mount error(13): Permission denied Refer to the mount.cifs( manual page (e.g. man mount.cifs) The man page does not have a list of error codes.

When trying to mount samba share off of domain member server sysimage in Windows receive error "There are currently no logon servers available to service this logon request". When trying to mount.cifs from PDC to samba share on sysimage receive error "mount error(13): Permission denied".
PDC is ClearOS 5.2 named "dc0" Samba file server is CentOS 5.5 x86_64 named "sysimage" dc0 Samba version is samba - 3.5.5-1.1.v5.i386 sysimage Samba version is samba-3.0.33-3.29.el5_5.1.x86_64
dc0 is configured correctly to my knowledge, windows machines can join domain, domain users can log into windows machines, user directories are mapped properly, logon scripts run properly. sysimage ldap authentication is set up as shown in "Procedure 7.1.
I had Fedora 8 installed in few clients and a server (same server for NFS and NIS), and NIS and NFS configured, and was working fine. Yesterday, I upgraded few client computers to Fedora 15 (server is still same), and configured NFS and NIS client. NFS is working fine, I can see home directories.
For NIS: ypwhich, ypcat passwd gives me correct uutput, ypbind is running. The problem is, I can't login to NIS client. The error is: Permission denied, please try again. My nssswitch.conf is
I'm having a permissions problem with Ubuntu and apache. There are two users, I'll just call them A and B. All of the files belong to A and group root. I'm logged in as B and I have admin privileges. My website is working just fine but when I create a directory in the web root, change the owner to A on the directory and all files I still get a Permission Denied error when I try to access it from the web. I've also set permissions to rxwr-xr-x on the directory and all the files. So I don't understand what's going on. Why am I still getting a permission denied error?
I want to use SSH to connect to my desktop. I have used Ubuntu 10.10's encryption to encrypt my home folder (thus encrypting my .ssh folder). This means that the OpenSSH doesn't have access to my .ssh folder. When I try to log into SSH before logging in on the local machine I get the following error:
If I log onto the machine, then use SSH it works fine. I want to use key based login, One way to get around this error would be use a different authorized_keys file, but I don't know of a way to do this. This is the contents of my sshd_config file:
# Package generated configuration file # See the sshd_config(5) manpage for details # What ports, IPs and protocols we listen for
I am using Ubuntu server edition 10.04.1 running in Vmware server 2.02.I am connect via Putty so I can use copy and paste.My first goal is configuring a ftp server using PureFtpd using this guide.In section 10 I need to write this command
I'm trying to create a folder using the archive manager to install Resin (web server) in the usr/local folder but I get the error message 'error creating directory: Permission denied.' Is this the easiest way to install an app--by using the Archive Manager--and if so how do I establish the correct permissions.
I'm breaking my head on this.I want to create a development environment. This means that I want to be able to create/change files myself, but php should be able to do the same. I installed a lamp-stack using tasksel. Afterwards I installed phpmyadmin. So far so good. Going to http://localhost shows "it works".
Then I created a folder /home/hwc/www and created a new apache site called hwc, disabled default and enabled hwc that points to /home/hwc/www and has the directive AllowOveride All set. But when I go to http://localhost know I get a 403 Permission denied error. I've tried several trings like changing ownership of /home/hwc/www to www-data:www-data, to hwc:www-data, to hwc:hwc, but all to no avail. Even adding www-data to group hwc and hwc to group ww-data did not help. According to other posts at least on of these solutions should have worked, but it did not. I could probably fix it by letting apache run as hwc, but that doesn't seem right.
