Debian Configuration :: No Longer Allowed To Access The System Configuration
Jul 31, 2011
I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.

I have recently installed Debian 504 AMD64, when I try to access "System" --> "Administration" --> "Users and groups" logged in as root, I get the following message:
"The configuration could not be loaded. You are not allowed to access the system configuration."
The system does not even ask for a password and the result is the same if I log in as a normal user.
I have installed from a single ISO DVD downloaded from the internet and read the DVDs of my previous Debian distro to install packages not included on DVD 1 of Debian 504 although I do not think this unusual approach can have any effect on the installation. I suspect I'll have to boot in single user mode but I have never done any troubleshooting at the command line.
(/etc/passwd and /etc shadow look OK).

I keep receiving the error message in the title above whenry to enterebmin.abc.com/webmin. I'm on Ubuntu 9.10. Other errors I'll receive are "You do not have access to any Webmin modules". Wondering if anyone knew what settings our permissions on files I could change to avoid these error

I have two machines running SQUEEZE, both installed and configured within the same week (not simultaneously). Both get the users info from a NIS server. In one of the machines (named "corona"), users cannot login, neither locally nor by ssh, in the other one ("xxlager") there is no problem. Both mount the users home directories by NFS. I have not found much useful info in the web. /etc/passwd, /etc/group/, /etc/shadow, are equally configured. The only difference I have found is when I use getent. Using "getent passwd isaenz" on xxlager yields:
isaenz:x:1001:1001:User Name,,,:/home/isaenz:/bin/tcsh
but on corona the result is
isaenz:x:1001:1001:User Name,,,:/home/isaenz:
so the shell info is empty.
Checking /var/log/auth.log I see a message saying:
"User isaenz not allowed because shell does not exist"
But "ypmatch isaenz passwd" returns complete information for isaenz, both on xxlager and corona.

I just installed Debian and am getting a problem where I can't open the list of network connections. I can use the network manager applet to connect to wireless networks, but I cannot access the network connections list from there either (right click "edit connections)
I'm not incredibly knowledgeable with Linux, but I tried a few simple things I could think of like reinstalling the packages, or restarting the interfaces. (ifdown/up wlan0)
It's strange, because when I click "network connections," I see it show up for a second on the bottom panel, I get some rotating mouse icon while I wait a few seconds and then if goes away. Is there some kind of logfile that could help me identify the problem?
Using Debian 6 on eeePC1000HEB with Ath9k (i think) wireless card. Net Interface: wlan0

This morning I upgraded two of my systems. The new 2.6.38 kernel fixed the missing pointer on the system that has an Intel video subsystem. Yay!
This afternoon I tried to upgrade my wife's systems. Aptitude is listing 2.6.32 as obsolete, but it isn't offering me 2.6.38. Was it withdrawn?

I have a problem. I'm using the latest Debian stable, Lenny. I am trying to get my usb wifi card working.
The Debian wiki advised me to upgrade my kernel to 2.6.30 using backports, because the drivers for my wifi chip are supposedly in the newer kernel.
So thats what I did. The install went fine. However, after rebooting the computer hangs when it is starting gdm. Only the desktop background appears with some fuzzy stripe over it, the mouse doesn't respond. Pressing ctrl+alt+f1 does nothing. I can only restart with ctrl+alt+del.
I can still use the computer with the old kernel. No problems there. I tryed disabling GDM and rebooting again with the new kernel. It boots up and works fine on command line. However when I type startx it hangs, just like before.
I'm not an expert, but I'm suspecting there might be problems with the graphic drivers in the new kernel.
When I installed lenny at first, X started fine. However 3d acceleration was not functioning. I got help from IRC, I had to install some package to enable direct rendering. Don't remember which one anymore.
Here's what lspci gives for VGA:
01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS

There is something strange going on with Pidgin in Debian 6. I have just installed the system, then Pidgin, then configured my MSN accounts and chatted; but after rebooting, it no longer works. It just hangs while trying to connect - this is what I see from strace:
[Code].....
- a largish number of times. My very rough and ready thoughts about this so far are that it is probably not Pidgin that has an error, since 1) It worked initially, and 2) I am pretty sure the developers would have know about it very quickly if this was a general problem in Pidgin. On the other hand, my networking seems otherwise to be fine - s what is going on here?

I upgraded from lenny to squeeze on a notebook and I can no longer connect to the wireless network. The computer is an LG notebook and the network card is ralink rt2860. I am using Gnome and NetworkManager. The wireless key is WEP hex. It was working fine with lenny till before the upgrade. After the upgrade, the network card stopped working. So, I checked
$ lspci|grep Network
08:00.0 Network controller: RaLink RT2860
Then I reinstalled the driver with apt-get install firmware-ralink wireless-tools Then the network manager tray started working again and saw the network, but cannot connect. It was trying to connect but timed out and kept asking for the password. It is the correct password. I tried deleting the old connection and recreated a new one in the nm. But still does not work.

I upgraded my testing/Wheezy Inspiron N5010 to 2.6.38-2-amd64 recently (along with a bunch of other updates, of course) and now my Samba network share is no longer automatically mounting, I have to open a root terminal and do a "mount /mountpoint"; my relevant /etc/fstab entry:
I've tried over options, as well, but it isn't automatically mounting. Any suggestions (including where to file a bug report)?

I try to fix bugs on my web server. The remote web server allows redirects to arbitrary domains. Description : The remote web server is configured to redirect users using a HTTP 302, 303 or 307 response. However, the server can redirect to a domain that includes components included in the original request. A remote attacker could exploit this by crafting a URL which appears to resolve to the remote server, but redirects to a malicious location.

we have moved and in the new apartment there's a connection with no external IP. Can I somehow access ssh from outside? There's absolutely no chance of granting a port from the ISP's side.

I have a windows based Domain Name Server (DNS) and I have a debian pc connecting to this network, obtaining an ip address via a DHCP server. I can ping any machine on the network using the ip address however I would like to be able to ping other machines on the network using their host names. For example I would like to be able to type... ping machine1HostName ... instead of ... ping 00.00.00.00 To do this I realise I need to tell debian to access the windows DNS but how can I do this?

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.

This is a perennial problem with Linux. I am just not comfortable moving a lot of casual files around as root. How can I have user access to a USB stick? I've done my Google searches and tried several methods, some of which work temporarily but not permanently. At the moment, I have this line in my /etc/fstab: /dev/sdd /media/usb_flash ntfs noauto,users,rw,umask=0 0 0
As with other methods, this worked last week but not now.
All I want to do is insert a USB stick, transfer some files and remove the stick. I want to do this as a user. This should be simple. What is the trick?

I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage.
Services like proftpd have:
AllowGroup ftpgroup
sshd have
AllowGroups sshgroup
And samba have
valid users = @smbgroup
But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf) Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password?

I've installed Debian on a Sun Ultra 450 Enterprise system using the net install version, so I know that my network is working correctly. However, now that Debian is installed and I bring up Gnome, I have no network access. I've set eth0 to DHCP, and have pointed it to my DNS server, but it never gets any information from the DNS server.
I've looked through /etc/network/interfaces, which looks like this:
# This file describes the network interfaces available on your system and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface allow-hotplug eth0
#NetworkManager#iface eth0 inet dhcp
/etc/resolv.conf contains:
nameserver 192.168.0.1
which is correct.
I've run
/etc/init.d/networking stop
/etc/init.d/networking start
So far, nothing works. Why would the Debian network install disk work, but not be smart enough to set my network correctly from the start once I'm actually running Linux? Also, how do I get the network running in Gnome?

I installed Debian Squeeze on my Acer AspireOne yesterday, and was delighted to see that my ZTE MF627 broadband dongle (from 3 UK) appeared to work "out of the box". I wasn't able to connect due to lack of signal, but the behaviour was as I expected. (The dongle is one with a "zero CD" that needs to be ejected before the modem itself can be accessed. Recent versions of udev are supposed to do this automagically.)
However, when I tried to use the dongle today, I was unable to make it work. It appears that udev is no longer ejecting the zero CD when it is inserted, but is instead detecting the modem as a (non-functioning) serial port.
Here is the output from /var/log/syslog for the "successful" attempt. Note the disconnection at 4769.479857 which is followed by reconnection as a different device:

Following yesterday's and then today's upgrade of my Debian 8 32-bit system (among other things to samba 2:4.1.17+dfsg-2+deb8u2 (yesterday: ...deb8u1)) I cannot connect my Mint 17.3 laptop to the server anymore. Were there any changes to smb.conf regarding authentication or other aspects that might lead to this problem? I am enclosing part of my smb.conf. By the way - I also have trouble using ssh to connect to the Debian machine, such as the ssh-command taking "for ever" and then getting the message "Write failed: Broken pipe" when entering an ls-command on the command line.

Let me introduce myself, my name is Carlos AlegrÃa from Chile and I'm System administrator for a educational Institute. We use samba+ldap, for login accounts and file sharing but we not use samba with PDC.
Long time ago at the 2009 year, I was Installing the same system and this worked perfectly. But on our summer the hard disk of server has broken, so i was need installing all the system again. So the problem is with SAMBA, when i connect to the network resource, this is to slow, and when i try transfer files are slow.
My sistem is on Debian 8 Jessie and the Samba Version is 2:4.1.17+dfsg-2+deb
Code: Select all[global]
  workgroup = LABORATORIO
  netbios name = Shinigami
  server string = debian

"My network" is behind a firewall inside a larger windows network with AD. My network has a Debian Server with samba 3.2 running. One of the hosts that are on the outside of my firewall has a share that I and other Linux-users on the debian server wants to access.

In a squeeze box, I installed awstats and it's working like a charm. Its cron job update the awstats database every 10 minutes (as it runs as root). But I would like to be able to update the statistics from the browser as well. So I setup everything as required and I gave "read" access to "others" to every apache log file. Now, a couple of questions came to my mind:
1. Am I compromising server's security giving "read" access to "others" to apache log files?
2. Instead of giving "read" access to "others", I could add www-data user to adm group (as apache log files are owned by root:adm and permissions are rw-r----). Is this more secure than giving "read" access to "others"? 3. If the option would be giving "read" access to "others" at the end, a log file would be owned by root:adm and its permissions be rw-r--r--. As apache rotates its log files, when Apache create a new log file, does it preserve the permissions (rw-r--r--) or create it with the default permissions (rw-r-----)?

I am having no luck configuring ProFTPd on a Debian Lenny production server we use to host our MySQL databases and a few websites. I had originally set it up so I could login and manage our internal sites, but I have the need to allow a few clients in to access their sites that we host. I am trying to root the users in their site directory, which would be "/sites/www.whatever.com/".
It just hit me while typing this. Is it possible to create a user without a shell to prevent login via SSH and set the home folder to /sites/whatever instead of /home/username? That would allow me to continue operating with my current configuration and root them in their site while preventing SSH logins.

i have a HP MSA 2312fc SAN with 2 LUNs configured. The first LUN (LUN ID 1) is correctly connected to the system, but when i connect the second LUN (LUN ID 30), i find in the syslog this message: multipathd: 8:64: size 6835937472, expected 5267578112. Discard
Here is the multipath.conf

So I correctly see the two luns, but multipath doesn't create the relative devices. Under /dev/mapper I see: control mpath0 mpath0-part1 mpath0-part1 is the first lun, the one I mounted in a directory under filesystem. I can't find the device for the second lun

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

I have a PC104 running debian. I have 3 hard drives (in addition to the one booting) mounted in fstab by UUID. I use the options defaults,error=remount-ro. However, this means that when I boot with the hard drives not attached, I have to press Ctrl-D to bypass when the boot discovers the drives are missing. Is there a timeout commandoption I can add to fstab so that it automatically continues booting even if the hard drives are not attached? I could not find anything on a timeout command. (I tried adding timeout=1000 but no-random guess)
