Debian Configuration :: Make Shared Directory Safe And Access Dir From VPN
Apr 4, 2010
I am planning to build a server in future. That will be a computer with GNU. It will be a router and file server. It will get the VPN-Internet and share it with all the PCs connected to LAN. There will be Samba for file sharing. And I'm thinking that if I just share some directory on that server with Samba, it will be possible to get access to that dir from VPN. So it's not very safe to do that. Is it possible to prevent access to Samba dir from VPN connection?

I've got a problem when I try to use to load modules like when I try : modprobe tun It says : FATAL: Could not load /lib/modules/2.6.32-4-pve/modules.dep: No such file or directory I've checked in my filesystem, the directory 2.6.32-4-pve doesn't exist, instead I have 2.6.39.2.110628 So how could I make modprobe look into the right directory ?

2 of us have been googling all morning trying to find out how we can restrict ftp logins to their own home directories only but nothing we've found so far has worked. We've tweaked sshd_config so that they default to their home directory but they are able to navigate up/across/down to everything. This is a "straight-out-of-the-box" debian 5.0.5 Netinst. Just a basic system with Apache/MySql/PHP/SSH and no desktop.

Unfortunately I haven't been able to figure out yet how to share specific directories only, so I set up my Samba server to share users' home directories (which is not a security issue here since the only possible client is my other machine). My user's home directory contains a symlinked directory on another hard drive partition, which I had to explicitly share to be able to access it from the other machine. This setup has been working for months now, but for a reason that escapes me at the moment it stopped working today, presumably after samba got updated from 3.4.2-1.1.3.1 to 3.4.3-3.2.1.
The error message on the client (Windows XP/SP3) for this one above mentioned directory, and for this directory alone, is "Access denied"; I can access all other directories fine.

I've a question about a connection to a shared folder on a pc behind an ubuntu 10.04 server. The Ubuntu machine itself is behind a Cisco router. Cisco router has a nat 1-to-1 to Ubuntu machine with the static public ip x.y.x.z The Ubuntu machine has one only interfaces eth0 bridged with a virtual tap0 in the virtual br0 interface. This because on the Ubuntu machine is running OpenVPN in bridged mode. I want to reach a private share on the host 192.168.100.2 using the x.y.w.z static IP. Is that possibile? Ubuntu machine has no firewall running (I was not able to run shorewall firewall for now).

I have an ubuntu server set up in which i would like my shared media directory to be accessable with multiple usernames / passwords because I use my admisistrator username and password for samba as well, but I do not want to give out that password to all clients in my house. And, I would like to have write permissions but keep other users to read only. Is this possible or do i need to just make one separate username / password for samba sharing?

Ubuntuzilla is an APT repository hosting the Mozilla builds of the latest official releases of Firefox, Thunderbird, and Seamonkey. This repository should also work on Linux distributions that are derivatives of Ubuntu, and probably also on any Debian derivative.

My system goes through slow periods where it just crawls and others where it's fine, but I'm wondering which service settings are OK to just shut off to give me a bit more oomph when I boot up.The others I'm pretty OK with like spam assassin, dictionary server and so on, but some of the others i wonder if they only serve to slow things down..Also..I live in a very dusty environment and I KNOW the fans and other parts get caked with dust and it wouldn't surprise me if the dust got so bad it just stops the fans completely so once in a while I use my air compressor to blow the crud out and I usually get covered myself, but how safe is using the compressor? It's not the type that typically fills up with condensed water droplets so that isn't a super critical issue..It's a small 1 hp deal, elect drive and so on.. Safe enough? It's all I have and/or can afford..

After adding a second ubuntu variant to this machine I wanted to share the home directories so I had easy access to the same files regardless. so I read up on modifying home directories and put in the correct location and then rebooted. On boot-up the system warned me that it could not access the "shared" home directory and after a few more errors and warnings ended up at a blank screen with a mouse pointer!. All I can do is access a term window (ctrl-alt f4). So what I need is to know is where the user properties are stored so I can go and edit those from term rather than the usual way!

I'm running a Debian based distro.
When I run ipcs this pops up:
This happens only while KDE3 is running. Regardless of the runlevel, if kdm is not started, this will not show.
By running ipcs -p the PID points to process
Is there anything wrong with that command?

Initially when I shrunk my NTFS Windows partition to install Fedora 11 I underestimated how much space I'd need for Fedora. Now that I'm using it as my primary operating system I have wasted space in the form of spare space on my NTFS partition. I was just wandering how safe it is to shrink this partition and move the free space to my /home partition using gparted on Linux? This would probably involve having to shift things towards the beginning of the drive as the Windows partition is at the beginning and the /home directory is at the end. Would I need to use a LiveCD to do this since it's meddling with an active operating system? I know I should back up the data, but is it quite safe to do it despite gparted in all likelihood having to move data from block to block across the drive?

I build and use a custom kernel, and use the nvidia driver. This is on debian stretch.
By default, I build the image and headers packages with this line:
CONCURRENCY_LEVEL=8 nice -n19 ionice -c3 fakeroot make-kpkg --initrd --append-to-version=-something --revision=1 kernel_image kernel_headers
These kernel sources are usually the sources from debian, with a couple of more patches that I add. It appears that for nvidia-driver package versions higher than 352.79-1, the kernel headers/sources need to be prepared with 'make prepare' and 'make prepare scripts'. It's that simple. I concluded this after the nvidia dkms build failed on my custom kernel, but then succeeded after I pointed it to the full sources, but only after running 'make prepare' and 'make prepare scripts' on them. The problem is that this make-kpkg scheme doesn't appear to do this, or if it does, it doesn't properly include in the headers everything that it should.

I had a pretty much standard installation according to some tutorial (I don't remember, which one) for courier, including ssl. After upgrading from Wheezy (7) to Jessie (8) everything continued working fine, excep ssl connections to pop or imap.
In the log I get this error message while connecting to imapd-ssl:
Code: Select allFeb 26 20:16:22 mx imapd-ssl: couriertls: connect: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher
First I thought there got some chiphers removed from default configuration. But even when I try to allow all protocols and all ciphers:
Code: Select allTLS_PROTOCOL="SSL23"
TLS_CIPHER_LIST="ALL"
And then test via s_client:
Code: Select all# openssl s_client -connect 127.0.0.1:993 -cipher ALL
CONNECTED(00000003)
3073349308:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure:s23_clnt.c:770:

---
SSL handshake has read 7 bytes and written 341 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported

TLS over STARTTLS is also not working and does not invoke a log-entry. So I want to solve the ssl-problem first. I guess the STARTTLS-problem is automatically solved then.
My update procedure was:

I run a network with about twenty Debian systems, currently running Etch. I maintain a central passwd and group file, which is regularly copied to each system. This works fairly well, but I have some problems with the system account UIDs and GIDs.
I find different systems often pick different UID and GID values for system accounts like bind, ntp, sshd etc. I think the values chosen at install come from the system UID and GID ranges, and are allocated sequentially, so the values on a system depend on which packages were installed, and the order they were installed in.
Is there any way to specify the UID and GIDs for system accounts at installation time? Are there any other thoughts on how to implement shared passwd and group files (apart from NIS, which I don't want to use)?

how to get clients connecting to an office printer. during a migration from windows server to debian/samba.
We have:
5 windows XP machines one Windows Server 2003 machine, PDC of the old domain One debian Samba PDC (of TEST domain)/print server (with CUPS installeD) running in a virtual machine hosted by the windows server One Toshiba eStudio 3511 printer
Using the CUPS control panel, I've been able to autodetect and add the printer, and it appears as an available share in SWAT for samba. However, the driver isn't perfect. CUPS could only supply drivers for the 3510c, not the 3511.
However, clients on the TEST domain are unable to access it. Doing so gives an error about a local policy preventing a connection to the print queue. I've tried googling this error and the fix that comes up in every result about changing a point and print policy setting, does not work.
however, I've been able to work around the issue. by first logging in as local administrator, navigating to the domain server, then inputting the domain root account credentials at the prompt. That allows me to attempt to connect to printers, but with a different error
"The server for the printer does not have the correct driver installed...."
I very strongly suspect that the 3510 driver actually will work, but it's just not being shared properly. The printer driver share folder is /var/lib/samba/printers, and that directory contains only a few empty subfolders. CUPS did not place the driver there as I would expect, and that is where clients are looking for it.
The thing is, I have no idea where CUPS DID put the driver.
On the old domain, the printer uses drivers for es4511, and looking on the toshiba site, this seems to be what they provide. The Toshiba Site provides a huge variety of drivers, including several windows ones, a universal driver, and a CUPS PPD. Cups asks for an optional PPD during install and I tried supplying that. It said installed successfully, but didn't change anything.
I've tried pasting the windows drivers into /var/lib/samba/printers/W32X86 too, and likewise with other drivers from toshiba's site. but this doesn't change anything either, so I'm at a bit of a loss.
how to install/setup drivers on a samba PDC, for windows machines?
Also relevant, my smb.conf:
anyone see any possible causes of problems?
# Samba config file created using SWAT
# from UNKNOWN ()

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.

has anyone been able to connect a Linux VPN client to a safe@office 500 using pre-shared keys?From windows, I can establish a IPSec/L2TP(also PSK) connection with no issues(No third party software. Just created a new connection in XP).I have tried using StrongSwan and xl2tpd on Karmic without success.PPPd never gets launched. To me it seems like this should work given I can create a vpn connection directly from WinXP without installing any checkpoint clients.

I am using Centos 5.2, and I installed all of the available gnome and gnome development libraries available via the "add software" menu item. Still, when running some programs, I get the following error message:
"error while loading shared libraries: libzvt.so.2: cannot open shared object file: No such file or directory"
If I understood it correctly, libzvt.so.2 is part of some gnome libs... where to find and how to install them?

I know that boot partition is possible to create within debian distribution that has grub 2.0, as I have done before with ubuntu. I have been trying many different options with my preseed file but it keeps taking the boot partition out of LVM and creating and extended partition too and then creates the LVM primary partition.
### Partitioning.
# you can specify a disk to partition. The device name can be given in either
# devfs or traditional non-devfs format. For example, to use the first disk
