I think my root drive is 100% full causing strange problems with my video server. What steps can I use to see what's taking up the room on the drive and perhaps identify files that can safely be deleted?
I recently installed Lenny and used the "Guided - Use Entire Disk" option.I made separate partitions for root, /etc, /var, /home, /usr and swap.I trusted that the auto partitioner would choose sensible sizes but possibly that was a bad move, root is only 340Mb and is full.
I am setting up a mail server on debian. Once it's done, I'd like to have an indentical server on another machine, where debian will also be installed. The solution has to be hardware agnostic, so source machine is different than destination machine. I was reading on some wiki page that one can simply copy the root filesystem via rsync to the computer that he'd like to install the system on, then chroot to it and test if everything works. I'm guessing I'd have to change a couple things before, like :
- The network config - The /etc/fstab file (disks and partitions may be different)
This article is about using rsync to transfer a copy of your "/" tree, excluding a few select folders. This approach is considered to be better than disk cloning with dd since it allows for a different size, partition table and filesystem to be used, and better than copying with cp -a as well, because it allows greater control over file permissions, attributes, Access Control Lists (ACLs) and extended attributes.

This only started after the recent updates which included a lot of sysv stuff in Squeeze. I'm not talking the Gnome or Xwindows consoles, I'm talking the full-on type you get when you do the CTL-ALT-F2 type of console. before those updates, I had no trouble. Now I can't get back into the gui by pressing CTL-ALT-F7 as usual. All i get is just a black screen. I do have the nvidia proprietary driver installed using DKMS, and I am running the latest (I think) liquorix kernel.
If this has been covered before I couldn't find it.
What I'm "Not" Asking... I'm not asking about installing the CD image to a USB hard drive to boot a live install version. I've done that to see is my computer will boot from the USB and it does.
What I want to do is this:
An actual hard disk install of full featured Linux to a portable USB Hard Drive. I want to be able to plug in the USB HHD and go Linux. (Why you might ask? Fair enough. The laptop is my wife's computer and she says absolutely no to Linux.
So, my issues since upgrading to Jessie seem to compound. When I fix one issue, two more arise. Right now, I have a full system disk. How it got so full. So I started poking around. I ran
Code: Select all find / -type f -size +50M -exec ls -lh {} ; | awk '{ print $NF ": " $5 }'
Found a few files I could delete, and did, but I also found Code: Select all/var/log/syslog.1: 33G /var/log/messages: 33G /var/log/user.log: 33G
What I find strange is that they're all exactly 33G each. So that accounts for the missing 99GB I deleted them, however only recovered 27Gb. Whats weird is when I type df -h I get
What are the tmpfs's and how can I reclaim that space, and what is /dev/dm-0 and why is that taking up so much space?
I have 2 LVGs vgdisplay -v
Code: Select allroot@SETV-007-WOWZA:~# vgdisplay -v DEGRADED MODE. Incomplete RAID LVs will be processed. Finding all volume groups Finding volume group "WOWZASERVER"
[Code] ....
After deleting the log files, I was able to regain access to my GDM session. But I still cant find out what /dev/dm-0 is, and where all the 75 GB is being taken up.
I just noticed, however, even though I can access the drive A-OK via browser, terminal, and web services (Our wowza) when I enter gParted I get this error for sda, my primary OS drive!
Code: Select all Libparted Bug Found!
Error informing the kernel about modifications to partition /dev/sda2 -- Invalid argument. This means Linux won't know about any changes you made to /dev/sda2 until you reboot -- so you shouldn't mount it or use it in any way before rebooting
Now that I'm in gParted I see 3 partitions: [URL] ....
It reports now, that I have used ALL of my disk space.
Post Log delete, and fresh reboot, this is what Code: Select alldf -h outputs
Having successfully installed SANE and gotten a scan from my ancient Mustek scanner, I thought I had it setup. But that was running in the root terminal window. When I try to run xscanimage from GIMP in my normal user account it doesn't start up. Running xscanimage in a normal terminal it says it can't see any scanners. Yes, I added my user account to the scanner group. What else needs to be done to let a normal non-root user access the scanner?
I have a "time-server". It's sending time to different devices through different ports/protocols. The problem is that it has no operator and that makes some extra difficulties.
Now when i try to start it using terminal Code: Select allsudo ./myprogram works fine and
Code: Select all./myprogram doesn't work.
It is so because without sudo i have no access to ports. As a result If i add my program to System->Preferences->Startup Applications it has the same problem. So i need to start it as root, auto-start, right after auto-login to system but without entering password cause nobody will do it.
Also I need to start ntpd but it also asks password sometimes I've tried googles but it offer a few ways with entering password that isn't suitable for me or writing some scripts/changing system files but with no example I'm afraid to break it all. So is there a way to start Myprogram and NTPD as root with no password entering?
My system is Debian 6.0.10 Squeeze, Kernel 2.6.32-5-686
Installed Debian 8.2 a while back, and I've been having issues with getting the machine to suspend correctly. If I try to put it to sleep when logged in to my regular user account the screen just goes black and then the computer hangs. However if I put it to sleep as root everything works fine. I do this by running this command (as root):
Code: Select allsystemctl suspend
What can I do about this? Worked fine on Debian wheezy..
Btw, just found this in the dmesg log. Connected perhaps..?

For my dissertation I created a debootstrap install of Lenny. When I boot this system I just can login with root without a password. When I want to ssh this machine with the debootstrap install I can't just login with root. I'm asked for a password which I don't have.
So I created one with passwd root and after that I can connect to the machine with ssh and the given password. But the machine still logs in with without a password.
I'm configuring some security and i'd like to run arpon to a specific device everytime wicd connects.So, if Wicd connects to a wireless, i'd launch gksu arpon -d -i eth2 (for example.) But this doesn't work, because it seems that gksu only works for X apps.I found that if i do: gnome-terminal -e 'sudo arpon -d -i eth2' It works, but it leaves me with a terminal window open, and i'd like to be asked for a password gksu style.I've also tried this: gksu -- arpon -d -i eth2which also works, but the program quits right after it's started.Am i missing something here?
We have setup Squeeze a Test machine , just for some tests, without network, Internet etc. and we need to allow root login in Gnome. We've changed /etc/gdm3/daemon.conf:[security] AllowRoot=truebut still doesn't work.
my debian laptop this morning ,saw that the update manager had updates..97 of them??? then when tried to view them the package manager freezes and becomes unresponsive. needed to do a few things and found my root password is NOT working. this all happened at the same time, i wonder if its related? have i been hacked? is this something new? cant reset root password (tried two methodeds with no luck) and cant view the updates altho i question 97 new updates are needed.
Is there a way where I can take like 50GB from my home folder (I have 375 avail., but using only 22GB) and put it to the root partition? Twice now my system has almost ran out of space on root, so luckly I was able to clear out old stuff so I don't have login issues after finding the hardway the first round lol. I just want to make sure I can login with out being forced back out because root don't have space to let me login.
I made a mistake in Gnome Disk utility tool. Instead of changing the options for a USB key, I changed the options of the root partition.
In Initial state, automatic options were desactivated. I just activated them. And after desactivacting them, I realized my mistake and switched back to "non automatic options".
By doing this, I suppose that defaults values were used since now, the system starts in command line mode and no more in graphic interface mode.
When I try the "startx" command, I get a "read-only" error.
With the command "sudo mount -o rw,remount /" the graphic interface is started.
Below is the configuration of the partition under the gnome disk utility tool :
"Mount at startup" is checked "Show in user inteface" and "Require additional authorization to mount" are unchecked
Mount options : nosuid,nodev,nofail,x-gvfs-show Mount point : /mnt/eb11d4d6-75db-XXXx-XXXx Identify as : /dev/disk/by-uuid/eb11d4d6-75db-XXXx-XXXx Filesystem type : auto
I do not want to change anything that could leat to a critical error. So what do you think I should do ?
I have squeeze with gnome. Various apps let me log in as root when needed to but if I logout as a user and try to login as root it won't let me (won't authenticate password). I had this problem before and reinstalled Debian and definitely checked for it to allow me to do this and it worked for a while after new install. Apparently some update overrode my preferences. This is a major defect and may force me to abandon Debian. I don't use root often but I don't have any use for a operating system that won't let me use it. Anyone know how to correct this. I am not interested in using a terminal on a regular basis or ever for that matter.
on my netbook I've tried to make possible for my user to shutdown without needing a password. battery could run low when I'm not in front of it. Editing sudoers has allowed my user to shutdown the system, but Gnome still prompts me for the root password whenever root is logged in too. That's usually the case, because to avoid entering the root password multiple times whenever I need elevated privileges and not wanting to cache the root password, I keep a Root Terminal always open.
I just installed Debian 6 on a server and when the server powers up, it shows me all the accounts I created in order for me to choose and login under an account, except for the root account. At the colo where the server is going, they need the root account at the login screen.
Reinstalled Debian Squeeze (64bit/gnome) on my Notebook using Netinstall. Everything worked like always but in the setup instead of typing in a root password as asked to i just pressed enter (in the hope of not having to type in a pw in the console later, just having to press enter then)
When i needed rootpw to install some software (using SoftwareDownloader) the normal loginpw seemed to work, but not in the console. ari@HP625:~$ su - Password: su: Authentication failure
I installed Debian Kit on my Asus Nexus 7 tablet, and after following the installation tutorial I got it running except for I'm stuck on the step to create a new user. (btw link: [URL] .... )
Here's how it went (I can't copy&paste from my tablet so I have to type out everything...):
Code: Select allroot@android-6c40984c21c156ae:/# adduser paul374 Adding user `paul374' ... Adding new group `paul374' (5000) ... Adding new user `paul374' (5000) with group `paul374' ... Creating home directory `/home/paul374' ...
[Code] ....
So since I read somewhere that selinux had some permission problem, so I did a few chcons:
...but still same thing as what happened in the beginning...
Anyway my goal is to create and be able to log in to another user so that I'm not stuck running root all the time. (Which, as we all know, is a bad idea.)
If there's a way to manually create the user by editing a few files, and root still won't be able to change passwords, I'm fine with that, as long as I have another user. Whatever it takes to just get a non-root user log-in-able...
I forgot to mention that since this is the Asus Nexus 7, there is no removable media, so chrooting from another Linux machine isn't an option, and neither is removing an SD card to use a LiveCD on it.
I'm using Debian Jessie Cinnamon right now. I've got 1 user account on my machine--fred--as well as root, of course. "fred" is an administrator, and many times that is enough for root priviledges, for example, I can install packages via apt or dpkg. However, I cannot access "Users and Groups", or install packages via GDebi, with my password. For that, I have to have the root password.
I know that it is possible to let the admin account handle everything and not even need root--for example, Mint and (I believe) Ubuntu do it this way. I don't know how, though.
Code: Select allgroups fred fred : fred cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth
I did disable the root account by Code: Select allsudo passwd -l root to see if it would make any change. Nothing different happened except that I now can't use GDebi or access "Users and Groups" since the root account and therefore password is inactivated. Not a big deal to get it back, though.
I have lost my password for my root and for my user account.
Code: Select alluser@debian:~$ su Password: su: Authentication failure user@debian:~$ su Password: su: Authentication failure user@debian:~$ su
I have just installed a gust debian 8 on debian 8 host in virtualbox, and when i wonted too login as su/root on the host there where no login possible, is there a way to regain the root password for the host?
My root filesystems flooded so I'm trying to move it to another (bigger) partition but I'm not sure of the best method. I just tried to use "dd if=/dev/sda1 of=/dev/sda6" to copy it but all that did was give me a brand new partition with no freespace available presumably because the filesystem is smaller than the partition. Is it possible to make the filesystem bigger?
The system crontab (/etc/crontab) uses the same format, except that the username for the command is specified after the time and date fields and before the command.
[code]...
Every hour, I get an e-mail complaining about the first line of the crontab:
[code]...
I get the same complaint from the other entries: It looks to me as if cron, or anacron, is trying to execute the user (root) as a command. Predictably, the shell doesn't like it, so barfs and triggers an e-mail about it. Why is this not doing what the man page says it should do? The 2nd problem I believe is related to exim, not cron. The e-mails I'm getting above are being bounced from my ISP because they are directed to root@myisp.com, rather than my regular e-mail address. When the message bounces, it bounces to my regular e-mail address. In /etc/aliases, I have root: [URL]... and in etc/email-addresses I have root: [URL]... Adding the entry to /etc/email-addresses allowed the bounce to find me because the sender's address is [URL]... but how can I get cron to send these messages to me in the first place, instead of root?
