How do the group-ids for the devices in /dev get determined during boot up? The system must get the defaults for the devices some time during the boot process. Where are the defaults listed?
Actual reason for my question is that I need a permanent change of "dialout" to "uucp" or, even better to "dialout,uucp" in this line:
Code:
crw-rw---- 1 root dialout 188, 0 Nov 14 15:00 /dev/ttyUSB0
when connection to a network the following error massage shown (unable to determine IP information for eth0. link not present)
and about the internet it said that the host not found
im using an Ethernet cable
I am trying to use a second sata 3.5 HD and at other times a USB 2.5 HD. Both prove a pain to use because Ubuntu tells me their permissions can not be be determined. They have only been partitioned to ext2 on Ubuntu. This happens on 9.04 10.04 and 10.10
I have searched the web about this found many answers which just do not work.
I want to launch Firefox at a different time every day, and send it to a landmarked page, not my home page.
Is there a relatively simple way to automate this?
How is the super user determined for the dialog box that pops up when trying to perform administrative tasks, "An application is attempting to perform an action that requires privileges. Authentication as the super user is required to perform this action."? Does it always ask for the password of the default user created during the OS install, or should it prompt for the current user's password if that person is an administrator?I use likewise-open for windows domain authentication, so I typically log in as a windows user that likewise-open has added to the list of users on this system. I have given this user sudo access and added the user to all the same groups as the default user, yet whenever I perform an administrative task in gnome I am prompted for the password of the default user. Is this normal? It seems like the behavior would be to ask for the current user's password if that user is an administrator, and if so what determines that the current user is an administrator?
View 4 Replies View RelatedI just did a fresh install of Fedora 11 and added Raid 1 for two additional drives during the install,
So, I have 3 drives. One with the OS, that I boot from. /dev/sdc
Then 2 others in a Raid 1 config, /dev/sda and /dev/sdb -- those are in /dev/md0
Everything with the system is fine. I can boot up, and everything runs great. So then I try to view the Raid and it looks ok when I open 'Computer'. it shows the main OS drive, and what looks like the 2000GB raid drive. So i open it and just see a 'lost+found' folder. Not surprising, b/c I haven't added anything to it. But when I right-click I can't create a folder b/c it's greyed out, I can't drop files in there, and when I get Properties on the drive itself it says 'The permissions of {driveid} could not be determined.'
How can I create a user group that restricts Internet privileges to only members in the group, then I will assigns certain applications to join the group for access to the Internet.
For example, I want only group net to have access to the Internet. Group net is then connected to:

So far, I am using the gnome group policy manager that is standard with ubuntu but Its not working. It is possible that im misdirected and that I should use a firewall instead?
I have a text file that currently has around 150 000 usernames in it. I need to somehow group them into smaller groups of 1000 and then add that value into the DB. for example user xzy group 1 (hopefully the groups will be digits incrementing)
[Code]....
how to search for 1000 then assign them group 1 and then 1001-1999 to group 2 etc.
I examined the problem, and determined that a huge amount of disk space is being taken up by files in /var/log/ The following files:
Code:
/var/log/messages.1
/var/log/kern.log.1
/var/log/daemon.log.1
/var/log/messages
/var/log/kern.log
/var/log/daemon.log
/var/log/syslog
are all over 1 GB in size. The largest is 18 GB. Together, they total 48.3 GB. I restarted the system, forcing a fsck.
I am wondering how I would go about creating a .deb file that would extract it's contents to two different folders. I would have one file directory that should be extracted to /opt and I have a second that should bextracted to the current user's home folder and /etc/skel - How would I go about doing this?

View 3 Replies View RelatedI've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)!
EXT3-fs: group descriptors corrupted!
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.
I just made a really nasty mistake. My system has an LVM for the main system using drive /dev/sda. There is a second LVM using drive /dev/sdb which was actually an old drive that I was using as a backup. In a fit of idiocy, I wiped the partition table on /dev/sdb. Which means I lost my backups, but hopefully only those. I can live with that. (I actually wanted to wipe the partition on /dev/sdc, which was an external drive...)
However, I now cannot boot. On boot, GRUB comes up, and Fedora 12 starts to boot. Which seems to be proof that I didn't delete my real system, since the old drive had an older version of Fedora (10 or 11) on it. This boot process dies during the fsck. Here are the approximate messages (copied on postit notes and running over to another computer):

Before creating this topic I googled a lot and found lots of forum topics and blog posts with similar problem. But that did not help me to fix it. So, I decided to describe it here. I have a virtual machine with CentOS 5.5 and it was working like a charm. But then I turned it off to make a backup copy of this virtual machine and after that it has a boot problem. If I just turn it on, it shows the following error message:
Activating logical volumes Volume group "VolGroup00" not found Trying to resume from /dev/VolGroup00/LogVol01 Unable to access resume device (/dev/VolGroup00/LogVol01) ... Kernel panic ...! During the reboot I can see 3 kernels and if I select the 2nd one the virtual machine starts fine, it founds the volume group etc. (But there is also a problem - it can not connect the network adapters.) So, it is not possible to boot it with the newest kernel (2.6.18-194.17.1.el5), but it is possible with an older one (2.6.18-194.11...)
I looked into GRUB's menu.lst and it seems to be fine. I also tried #mkinitrd /boot/initrd-2.6.18-92.el5.img 2.6.18-92.el5 no luck! Yes, I can insert DVD .iso and boot from it in "linux rescue" mode.
I have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP
...
GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW
[code]....
Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?

View 4 Replies View RelatedI have a number of users, categorised into various groups. I would like one of those groups ("developers") to be in the wheel group as well. I don't want to just copy the people from the developers group into wheel, because then when that group changes I'll have to change it in two places. Is there a way to specify that anyone in developers is in wheel, and have that be dynamic?
View 7 Replies View RelatedAfter upgrading to Lucid 10.4, I find that after booting I can no-longer auto-mount any USB drive when they are plugged in. They simply doesn't appear on the desktop as they did. Swap my PATA drive back to the one with 9.10 still installed on it is well.However, if I have USB drives plugged in before boot, they appears on the desktop, but are not auto-mounted as previously. Also when I click on any drive icon for the first time there is no response. Try again (on any drive) an the devices will all auto-mount revealing their contents in the window that subsequently opens. Everything them seems fine. I can unmount and remount at my leisure with any number of devices.
I do not have the problem of root only access that others have mentioned. I have played with usbmount and pmount as others have suggested, to no avail. They have both been removed.I have the HAL installed as default, and have already ecked media_automount_open for Nautilus on the gconf-editor.Disabling the floppy in the BIOS has not effect and I do not use autologin option.With (say) two USB drives attached, whether the devices are recognised at boot or not after boot,lsusb reveals:

View 1 Replies View RelatedI have a relatively new server (Ubuntu Server 10.04.1) with a "/backup" partition on top of LVM on top of an MD raid 1.Everything generally works, except that it freezes during the fsck phase of bootup, with no errors. I've given it 20 minutes or so. If I press 's' to skip an unavailable mount (documented here), it reports that /backup could not be mounted.here are no LVM related messages in /var/log/messages, syslog, or dmesg.
When I try to mount /backup manually, it reports that the device (/dev/vg0/store) does not exist. Apparently the volume group was never activated, though all documentation seems to claim it should happen automatically at boot. When I run "vgchange vg0 -a y", it activates the volume group with no issue, and then I can mount /backup./etc/lvm/lvm.conf is unchanged from the defaults. I've seen posts mentioning the existence of a /etc/udev/rules.d/85-lvm2.rules , but no such file exists on my server, and I'm not sure how I would go about creating it manually, or forcing udev to create one.There are some open bugs describing similar problems, but surely it doesn't happen to everyone or there'd be many more[URL]
One question: should F13 mount all attached USB devices after boot automatically? I guess it should. However, what I've experienced is that after boot and login, my USB modem + flash memory is not mounted. I need to manually unplug it and plug it again, and then it's mounted
