Debian Configuration :: All Users Not Able To Write To USB Stick

Jan 5, 2011

I have a USB stick, formatted as FAT32 and I assumed that everybody would be able to read from and write to it. However, I find that if more than one person is logged on to the machine (logged on locally, with "Switch User"), then only one of the users is allowed to write to the stick, and the other users are only allowed to read from it. Is that normal?

Here's the scenario: person A logs into the machine, is in the middle of something but gets called away and the screensaver kicks in. The screen is now locked. Person B comes to the machine to quickly copy a file onto a USB stick, doesn't know person A's password so does a "Switch User" and logs in as themselves. They plug in the stick, can read from it, but can't write to the stick at all. Permission denied.

By doing a "ls -l /media", person B can see that the stick is mounted but is owned by personA with permissions drwxr-xr-x . So only person A can write to the stick. I haven't done extensive testing but it seems to be the person who logged on first who gets to own the stick. It's certainly repeatable as described above. And it's really annoying, because unless person B knows the root password, he can't write to the stick. As a real last resort person B could reboot the computer but he doesn't know whether person A has any important stuff open or not.

Debian Multimedia :: Disable Write Caching For Removable Media?

Feb 9, 2010

how to make removable media (e.g. USB sticks) not have any write caching. I want to prevent data loss when they are removed after file copying appears done but before write caches are written. I'm using Gnome on Squeeze.

I've found suggestions of adding the 'sync' mount option to /system/storage/default_options/vfat/mount_options in the Gnome configuration. However this doesn't seem to completely eliminate write buffering, as the drive activity light continues for several seconds after file copying appears done, and unmounting drives produces a dialog box which says to wait whilst data is written to disk.

Debian Configuration :: HP Media Bar Not Working

Jul 4, 2011

I would appear that I recently installed linux-image-2.6.32-5-amd64. Since then I have noted that my HP media bar up top doesn't work. This means I can't enable/disable wireless. From an lspci output, it still sees the hardware, and it's loaded, however, not functioning. Should I be looking at rolling the kernel back, or work on getting it working via some other means? Any liveCD I've tried doesn't seem to be able to get it going either. So I'm under the assumption here it is the kernel version, and not a hardware problem.

lspci
00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) .....

Also tried this to no avail:
sudo apt-get install rfkill
rmmod iwlagn
rfkill block all
rrfkill unblock all
modprobe iwlagn
rfkill unblock all
ifconfig wlan0 up
SIOCSIFFLAGS: Unknown error 132

Debian Configuration :: Systemd Automounts For Removable Media Not Timing Out

Jul 18, 2015

I have the following hardware setup:

a NAS running Debian that frequently (but not always) has two removable media attached,a Debian desktop that mounts the above NAS via sshfs,the aforementioned removable media are symlinked to the directory on tha NAS that is then mounted by the desktop.

What I'd like this setup to do is to immediately time out if mounts as unavailable. Instead, I only get the expected behaviour if the NAS is down (the ssh client takes about 3 seconds to do that); if it's up, the removable media automounts (they are symlinked to the directory shared with the desktop) seem to never time out, ever. This happens locally on the NAS as well, when ssh'ing to the NAS and trying to run `ls /media/Storage` or `ls /media/Backup`, these commands never return. It's as if systemd was ignoring the x-systemd.device-timeout setting on the NAS.

The relevant part of the NAS's fstab:

Code: Select all/dev/sdb1       /media/Backup   ext4    defaults,noauto,x-systemd.automount,x-systemd.device-timeout=1s,rw,user,nofail,x-systemd.idle-timeout=30s       0       1
/dev/sdc1       /media/Storage  ext4    defaults,noauto,x-systemd.automount,x-systemd.device-timeout=1s,rw,exec,nofail,x-systemd.idle-timeout=5min      0       1

[Code] ....

I find it highly interesting that despite both removable media being detached, only one is flagged as having a dependency failed. Both paths exhibit the hang behaviour, though.

What can I do to actually time out when the media are not there?

Debian Configuration :: Root Doesn't Have Permission To Change Passwords

Jun 19, 2014

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:

Code: Select allchcon --user=u --role=r --type=init --range=s0 /etc/passwd
chcon --user=u --role=r --type=init --range=s0 /etc/shadow
chcon --user=u --role=r --type=init --range=s0 /etc/gshadow

And it did take effect:

Code: Select allroot@android-6c40984c21c156ae:/# ls -Z | grep passwd
            u:r:init:s0 passwd
u:object_r:unlabeled:s0 passwd-
root@android-6c40984c21c156ae:/# ls -Z | grep shadow
            u:r:init:s0 gshadow
u:object_r:unlabeled:s0 gshadow-
            u:r:init:s0 shadow
u:object_r:unlabeled:s0 shadow-

...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.

Debian Configuration :: Apache - Permission Denied On Files Uploaded Ftp?

Apr 12, 2011

I have an apache installation with /var/www/bob as the document root and the only site served up. I have bob as the directory's owner, and he is able to upload his files to that folder via ftp (vsftpd on the server). When a browser tries to access the pages, it simply gets a 403 forbidden. The problem occurs when apache2 tries to access the files bob uploads. The www-data user (Apache daemon) gets permission denied when I try to cat bob's files in the shell, so it's purely a permissions issue. What I can't figure out is how to give the Apache daemon the ability to read bob's files while also making certain it does not have the ability to modify any of them.

Debian Configuration :: Specify Different Languages For Different Users

Sep 27, 2015

I have Debian 8 installed, using:
* gdm3 as the default display manager (set up in "/etc/X11/default-display-manager");
* LXDE as the default desktop environment.

I did "dpkg-reconfigure locales" and I selected three languages: "en_US.UTF-8", "it_IT.UTF-8", "sv_SE.UTF-8" (the predefined one is "it_IT.UTF-8").Now I wish to create two more users each with a different language (both for X and console applications).I did a lot of googling without success; I tried modifying ~/.profile or ~/.dmrc (adding "export LANG=...") but they didn't work. I was able to change only the system-wide language, not the one of a single user.I got the conclusion that It's not possible to have multiple users each with a different language. Is it true?

I made another try.In another installation (Debian 8, with GNOME and LXDE) I created two users:antonio, ida.The former has only one hidden file in its home-dir: ".bashrc" with "LANG=it_IT.UTF-8" as the last line (no "export $LANG" added).The latter ("ida") has only two hidden files in its home-dir:

1. ".bashrc" clean, with no "LANG=it_IT.UTF-8" line
2. ".dmrc" containing two lines:

Language=sv_SE.utf8.I put "/usr/sbin/gdm3" in "/etc/X11/default-display-manager".After reboot both users are OK: each of them displays its own language: antonio has all menus and programs in italian ida has all menus and programs in swedish.

I was able to create 4 users with 4 languages (SE, IT, FR, ES). Then I deleted all directory and files (including "~/.bashrc" and "~/.dmrc") of one user, rebooted the PC, and NOTHING changed! So, where is stored the user's language?Not in his home; there is a list elsewere?

0. Use "lightdm" (not "gdm3") as the display manager (see "/etc/X11/default-display-manager")
To install it: su -c "apt-get install lightdm"
1. su -c "dpkg-reconfigure locales"
(select the desired locales: en_US.UTF-8, it_IT.UTF-8, sv_SE.UTF-8, etc; set "default locale for the system environment=None")
2. su -c "adduser emil" ("emil" is the name of a swedish user)
3. Logout
4. Select "Swedish" as default language (see at the top-right corner of the screen)
5. Write user name (emil) and password to login
6. After login, language is english (but file "~/.dmrc" is created with the correct language).
7. Reboot PC.
8. After reboot, login again as "emil": now language is Swedish

Now you can change the display manager to gdm3 if you prefer.To change applications language: su -c "apt-get install task-swedish task-swedish-desktop"

I found the file containing the user's language: it's the same containing the link to its icon:/var/lib/AccountsService/users/UserName.(needs "apt-get install accountsservice"). Editing that file is much simpler as I described earlier

Debian Configuration :: Plex Media Server Suddenly Stopped Working

Jan 27, 2016

My plex media server suddenly stopped working after years of no hassle use. This is the output of cat /proc/version = Linux version 3.2.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.65-1+deb7u2

My problem is similar to this forum thread viewtopic.php?f=5&t=121945 where I can get it to start by running Code: Select all/usr/sbin/start_pms & but it's not my normal server configuration. I added a couple files to it and it seems to work except it doesn't start when I reboot. I have to run that command again.This is the init script I've been running for years...

Code: Select all----
#!/bin/sh
### BEGIN INIT INFO
# Provides:          plexmediaserver
# Required-Start:    $remote_fs $syslog $networking
# Required-Stop:     

[code]....

My Debian skills are lacking to know how to proceed with troubleshooting what could have happened. Everything else seems fine, I just can't seem to get this application to run at startup or get back my old configuration...

Debian Configuration :: Abysmal Write Speeds Over Network

Nov 11, 2010

Linux beginner, first project is a NAS based on Debian Lenny. Have SMB and AFP running. Hooked to a gigabit network. 8 disk RAID6 with mdadm. Need the NAS to back up our production company's video files.First attempt at back up was very, very slow on smb and afp. Used a Mac disk benchmark app, shows 100+MBps reads, but only .4MBps (as in 400kbps!) writes. Went through office LAN, and also tried just cabling the two machines (MacPro and Debian NAS) directly. Same results. Not sure what the write speeds are internally, as I don't know of any Linux/Debian disk testing software.

Debian Configuration :: Environment Variables For All Users

Nov 27, 2015

I'm newbie on Debian, and I just installed Debian 8.2. (I used to run openSuse, and I see Debian is quite different.)

Where should I set environment variables (like PATH or JAVA_HOME) in order to affect all users?

I read some documentation about that, but It is not clear for me, the difference among "/etc/environment", "/etc/bash.bashrc" and "/etc/profile".

(In openSuse, I used to create a file "/etc/bash.bashrc.local" and set the environment variables there, in order these settings are not lost with updates.)

Debian Configuration :: Can't Use /bin/false As Shell For FTP Users?

Feb 2, 2010

I have vsftpd installed on my Debian (squeeze). I wish to let a local user (ftp) access the FTP server, but not login as normal user through SSH. In vsftpd.conf, I have enabed local user and chroot. I have also changed the shell of the local user (ftp) to /bin/false. The problem is that, I cannot login the FTP server from another computer (I login as "ftp" on a Windows machine). But when I change the shell of the local user (ftp) to /bin/sh, I can login the FTP successfully.

Is this the problem of Windows, or I should use something else instead of /bin/false if I want to prevent "ftp" login service other than FTP?

Debian Configuration :: FTP Users Do Not Have Access Via SSH, Only User ID?

Oct 23, 2010

It looks like my web/ftp server has been hacked but I'm not sure how. I logged in tonight and found I had new mail. I read it and found some e-mails that had failed to send because I don't have mail setup (luckily). The e-mails were trying to send my user name and password to the e-mail address lostsoul2k@ymail.comI've no idea where to start, I use SSH, FTP now and then and it hosts a Wordpress site. The FTP users do not have access via SSH, only my user ID. However, the e-mails also contained another user ID that only has FTP access to the server.I've looked through the logs for rkhunter but it doesn't look like it found anything.

Debian Configuration :: Migrate The Users Without Resetting Their Passwords?

I have already copied the passwd, group and shadow file with the user accounts information but the Debian machine doesn't let the users login. I have already looked in the pam files to make it accept the MD5 encryption without any luck. how can i migrate the users without resetting their passwords?

Debian Configuration :: Newly Created Users Can't Login?

Aug 27, 2010

i've written a bash script to add new users to our system. the script works so I won't bother you all about that. when a new user is created with it, they can immediately login to our domain from any terminal, which is good. However, the newly created user is unable to login to debian at all, and so cannot access the server. when attempting to do so, they get a message like "the system administrator has disabled your account". This is a good thing really as normal users have no need for debian login, but I do need to add a few admin users who will need direct access to the server machine.

/usr/sbin/useradd -g smbusers -d /home/$username -s /bin/false -m $username
passwd $username
smbpasswd -a $username

This is the code I'm using to add the user. The rest of my script is just a wrapper and GUI. I figure the login shell may have something to do with it, so I tried changing the shell of a user to the default /bin/bash. This resulted in the user being able to login - sort of. Gnome doesn't load though, and there's a cascade of errors across the screen about things failing to save or load settings. mostly stuff like nautilus, X, and gnome. the desktop background is black and there's no interface. Logging in with a previously existing account works fine though. Clearly I have an issue somewhere.

- www-data (obviously no Apache is installed)

I was wondering if there was a way to avoid this from a minimal install?
