I have installed a driver on SUSE, and changed permissions for it (/dev/name) with the chgrp command.
However after rebooting my computer the change is lost. How can I save the permissions for the device?
I wanted to save a python program because I am reading byte of python and I went to save in !/usr/bin. When I try to save in this folder I get this error "[Errno 13] Permission denied: 'usr/bin/helloworld.py'.

-rwxrwx--- user1 group1 file1.txt
-rwxrwx--- user1 group1 file2.txt
When user2 (who is also a member of group1) edits file2.txt the permissions change:
-rwxrwx--- user1 group1 file1.txt
-rwxrw---- user2 group1 file2.txt
user1 then has issues opening the file. This also goes for new files that are created (they are missing the group execute permission).
I have set the option "create mask = 0770" in my smb.conf. Without this set, permissions default to something like -rwxr--r--
I just setup a FireWire audio interface. Everything works fine, except for I need rw-rw-rw- permissions on /dev/fw0. I can always sudo chmod 666 /dev/fw0 just before setting the thing up, but then it will be gone on the next rebooting.The solution to modify /etc/udev/rules.d/020-permissions.rules (which is for Ubuntu Breezy) doesn't go well for Ubuntu 10.10 Maverick because there is no /etc/udev/rules.d directory.

View 9 Replies View RelatedStill getting the "cdrecord has no permission to open the device" error when trying to burn an iso image to a DVD-RW.
I did yet another clean install of openSUSE 11.2 64 on my desktop computer, did updates, added Nvidia and Packman repos (it's not a repo problem as I tried it several times on a totally clean install), added codecs and stuff as advised by caf.
I updated the DVD drive firmware earlier today.
My user is a member of ALL groups.
Drive is an LG GH22NSS50 (sata)
It all works (with the same DVD-RW) under winxp on the same machine.
Is it HAL or something else that blocks permission to devices?
I'm really getting sick to death of this problem, and would be happy just to get rid of anything blocking permissions to the DVD drive.
I recently compile Kernel 2.6.34 (to fix the AMD PowerNow issue with 1055T processor, and it worked!) However, the device
/dev/shm
starts up at boot as Read-Only.
Google Chrome requires this device to be user-writable, or it won't start up. Presumably, the stock kernels (and all that are updated) have it set to User-Write. I have not noticed any other ill effects with the permission being read-only. If I do:
sudo chmod a+w /dev/shm
Everything will work from there, but each time I reboot, I have to do that. How do I make that permission-change permanent?
I am new to k3b and trying to burn an iso and get the following message during the burn process .
"CDrecord has no permission to open the device".
I was trying to burn an .iso with K3b a little while ago, and had some problems. First of all, even though I chose 8x to burn my (16x) DVD, it switched to 11x or 12x around halfway through the burning process. There were also some ticking noises that I'm pretty sure were coming from the DVD writer, not terribly loud, but noticeable. This had never happened before. Finally, it got stuck at about 98% (but not frozen, as the time elapsed kept going), and did not finish burning--got an error message (and a bad disc): "cdrecord has no permission to open the device"
I inspected the disc and there was one dark spot (on the dye) about halfway through the disc, very thin and couple of millimeters long. (This was present only after burning). I'm using Ubuntu 10.04, K3b version 1.91.0, Lite-On DVDRW SHW-160P6S

Hello,
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.
my sript runs:

Even a simple:
scanimage -Lv
in console gives this on a separate --current pc as well.
On one of my machines the DVD/DVDRW/CDROM drive appears as /dev/hdc and is not identified as an optical drive by HAL. It is owned by root: disk and thus no users get permission to read/write in the device (not even those in the cdrom group). This stops playing DVDs, ripping CDs, no notifications appear when a disk is inserted, etc. etc. When I set the permissions for all to read/write from the device then users can access but still no notifications are shown.
On all my other machines the optical drive is identified as /dev/sr0 and is owned by root:cdrom . All have Slack 13.1 . Previously with Slack 12.2 this machine still had the drive in /dev/hdc but the permissions were right (I think because I added it to /etc/fstab with options for users to access it). I believe the problem is down to HAL not setting this drive to the correct group, but how do I fix it? I hate HAL, it has a mind of its own, just like in the scifi movie
I tried to burn with k3b but after a while the fateful message "cdrecord has no permission to write to the device. " Then I launched k3bsetup and I selected the burning group. Did not exist. I created it and now i'm included in it. Then I checked all the boxes for the write permissions of the programs used by k3b and the writer. Now it works. But after reboot, the box of the burner device is not checked. So I have to select it each time. Boring. DO you know how to save the setting permanently

I want to save notes against a file on linux... i want to save meta data about a file..because the file names are restricted in max length...So how to save notes or comments about a file on linux so that it gets saved along with the file itself...I used the notes tab in the file properties dialogbox.. but that way the notes stick to the file only on that OS only.. if i open that file in another linux os.. those comments/notes are gone...Way to embedd these notes into the file so that i dont lose them ever..At lease a solution that makes this possible on switching linux distros. if its not portable enough that these notes stick b/w windows and linux its ok for me.. but atleast if i format my linux os.. atleast i shouldnt lose those important notes..and be able to access on newer linux..
And i also have no idea if this notes tab was implemented to be linked with the OS only.. i dont see much use of it.. and a normal user also has noway to know this.. i also came to know on superuser chat from a buddy.. @Sathya ..this thing is more useless especially if u use ubuntu which has 6 months timeline..and crazy people like me who are always eager to upgrade their os as soon a new one is available..and any way i can search these notes from the terminal?

View 2 Replies View RelatedI often send and receive gpg-encrypted mail. At the moment I use thunderbird + enigmail (in linux) to do that. As far as I know there is no way in thunderbird to find all encrypted messages which bodies contain particular keywords. There also seems to be no option to save encrypted mails decrypted (so they would be searchable). However for me it is important to be able to search old encrypted mails.
Is there a way in linux to save incoming mails automatically decrypted in my inbox and save outgoing encrypted mail decrypted in the send folder? Both times adding a line to the body which remarks that the mail was encrypted.It could be another email client for linux that could to that or perhaps a solution using procmail or maildrop.For a procmail solution I guess there could be some problems with encoding (perhaps one have to use emil?). Note that the solution should work for multipart encrypted messages (including encrypted attachments) too. The point is that the mails are encrypted on the mailserver or more generally on their "way through the net".
An external 3½" HDD seems to be in danger of failing” it's making ticking sounds when idle. I've acquired a replacement drive, and want to know the best strategy to get the data off of the dubious drive with the best chance of saving as much as possible. There are some directories that are more important than others. However, I'm guessing that picking and choosing directories is going to reduce my chances of saving the whole thing. I would also have to mount it, dump a file listing, and then unmount it in order to be able to effectively prioritize directories. Adding in the fact that it's time-consuming to do this, I'm leaning away from this approach.
I've considered just using dd, but I'm not sure how it would handle read errors or other problems that might prevent only certain parts of the data from being rescued, or which could be overcome with some retries, but not so many that they endanger other parts of the drive from being saved. I guess ideally it would do a single pass to get as much as possible and then go back to retry anything that was missed due to errors.
Is it possible that copying more slowly — e.g. pausing every x MB/GB — would be better than just running the operation full tilt, for example to avoid any overheating issues? For the "where is your backup" crowd: this actually is my backup drive, but it also contains some non-critical and bulky stuff, like music, that aren't backups, i.e. aren't backed up. The drive has not exhibited any clear signs of failure other than this somewhat ominous sound. I did have to fsck a few errors recently — orphaned inodes, incorrect free blocks/inodes counts, inode bitmap differences, zero dtime on deleted inodes; about 20 errors in all.The filesystem of the partition is ext3.
I loved Gnome's Nautilus and FTP integration and being able to mount a remote FTP directory as a regular bookmark/directory, and double clicking any remote files to open in any unmodified program. I also loved editing text files with GVim.
However, if I double clicked file on Nautilus to open a text file in Gvim, then saving a file will take about 10 seconds and GVim will hang for that amount of time. The major irritant is that I cannot continue editing while the text editor is waiting for the write to finish, this delay interrupted my workflow and thought process and saving becomes a painful process. The other problem is that I don't think simply uploading a file should take that much time.
I'm aware of GVim's internal FTP support, but they are not as well integrated with Nautilus's FTP and it suffers from the same problem.
So a few question:
Is there a way to make GVim or GVFS to save in background while I continue editing?
Why is GVFS so slow? Is there any way to set GVFS to use a single persistent FTP connection instead of creating a new FTP connection each time?

i decided to try archlinux in my pc a while ago so i installed it... after three months i started to miss slackware so i decided to reinstall it but i wanted to save my /home partition so when i installed slackware i left my /home partition from arch hoping that i could just mount it on slackware...but now when i try to mount that /home partition this is what i get:
bash-3.1# mount /dev/sda4
mount: wrong fs type, bad option, bad superblock on /dev/sda4,missing codepage or helper program,or other error In some cases useful info is found in syslog - try dmesg | tail or so
code....
So i dont really know what is going on here but i hope somebody could help me because i really NEED to get the data from that partition.
oh and by the way i installed slackware on ext4 partitions and the /home partition from arch is ext3 so i dont know if that's maybe the problem o_O?
When I reinstall my distro (MEPIS, for the last 2.5 years), making my new user account preserve all the old account's settings has always been a difficult and very messy process, especially if I have installed a new copy on another partition. (I'm doing that soon, so I have this copy as a backup until I have everything the way I want it on the new copy.) Most of my stuff gets saved, but not everything. The biggest problem is that, even if I select "preserve data in /home" in the MEPIS installer, my keyboard shortcuts become unusable (not completely erased) under odd circumstances. They're still listed in file /home/josh/kde/share/config/khotkeysrc, but they still can't be used, and I have to open hhotkeysrc and manually delete them and then reenter them in the menu editor (the K menu, by the way, gets completely overwritten).
I can't just overwrite the entire new user account with the old one; I've tried, and something goes wrong so that the new account can't be opened (probably because some important files are inaccessible--I can't tell which ones they become inaccessible).Anyway, is there a program that can preserve all the user account settings neatly for a new installation of the distro? I am supposing there is a program or at least a method, because I never hear others complaining about this problem. I probably don't know something I should know.
I usually work with plain text files, and when moving them across platforms, the differing format creates problems. I want that whenever I save a file with extension *.txt, it be saved as DOS format, and all other extensions or without get saved as Unix format.
