I got my FTP up and working but I want to make it secure.
If I leave anynomus users turned on it works just fine but I want to have some security over it and don't want anynomus users.
No matter How I try and connect to it if I turn off anynomus users it will not let me connect.

I have an old server running CentOS 5. The encription method used was the default MD5 for the shadow file. I would like to migrate the server to Debian Squeeze which uses SHA512. 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?

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.

I need to setup a way for our Web Developer to login to this particular server to manage the webpages that are hosted. He prefers to use his ftp client/fireftp since he connects to all other servers that way. I can connect via local network but can not seem to connect from my home computer. We have a firebox firewall and we opened port 21. Do we need to open any other ports or just port 21?

We're syncing users from Active Directory over to our linux LDAP server (Red Hat Directory Server). The user names on the AD side are all written in uppcase letters, which is the company policy.The uppername usernames causes problems when setting up /etc/sudoers, since uppercase words are interpreted as aliases. For example, if I add user KENNETH to a User_Alias (i.e. something like "User_Alias ADMINS = KENNETH"), I will get a warning from visudo which expects KENNETH to be an alias and thus not a username. Despite the warning, sudo does seem to work correctly. But is there a way to tell visudo or sudo that usernames are uppercase, and should not trigger a warning? Or are there other ways to go about this sort of thing?

I have successfully installed squid proxy server for my college . Then i used proxy authentication for 10 users using htpasswd command in a simple text file with encrypted password. It works fine.
My request is that I have to manage 2000 usernames of students for authentication . How can i do this ?
Is that single text file capable of holding 2000 usernames and password for authentication ?

Lately I adapted my /etc/fstab to mount samba shared network drives. I had to put the password in the configuration file in order to log in automatically. Isn't there another way? It feels a little akward to me to put passwords in a plain text-file.

While I've been using Linux for a little while now, I have only recently been getting into setting up and using a server at home (in part because until recently I only had ONE computer at home). I have heard of LDAP and OpenLDAP, but I am not sure if this is the best tool to do the following. Centralize logins and passwords for all of the computers at home, so I only have to change/manage one place. Since I keep installing Linux Distros it would be nice if I didn't have to add each person, individually each time.
Provide single sign-on authentication for the user so when they go to the Samba server they don't have to do another login, but they are limited in what they can see. Basically I don't want the kids being able to see *MY* files
- Works with Linux (various) and Windows (Windows 7 more than XP)
- Works with desktop and laptop
- Be able to, possibly, pass this authentication to the web server so likewise do not need to log into the web server after logging into the computer.
- (optional) be able to set up a script to run automatically to either map network drives or mount samba directories based on the user being logged in (smb://user/<username>) and/or backup the system.
I say optional because if it can that is great, but if it cannot then it isn't a show-stopper. Like I said, I am very new to servers and networking and do not know where to start regarding this. Right now I have a basic (too open) file server and a web server just beginning to be developed (working on Drupal). Not only do I need to figure out what/where to research about the server settings but also setting up the client-side of things.

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.

From yesterday on, I am not able to connect my Laptop to my WiFi Router automatically when logging in to gnome desktop.
The following is the message found in /var/log/messages.
Its Lenny 5.0.4 and I can see my wifi LED ON till the gdm login page. After the login, while loading my desktop, the LED goes OFF and I have to restart the network-manager for enabling the wifi again. Why is this happening? Do I have to change the configuration settings in /etc/dbus-1/system.d/ to fix this. I really don't know what change needs to be done there and where.
The same day when this problem started while logging in I got an error message from nautilus. The screen-shot is attached with this mail. Does this error have anything to do with the network issue?

I'm new to the world of linux I've started using it just one week ago.I installed Debian Lenny without problem, and after 2 or 3 days managed to make my wifi and ATI card to work. Today I tried installing compiz, through the packet manager that comes with the system. It was downloaded and installed successfully, so I rebooted to see it effects (I guess) but after that, I wasn't able to get to the login screen anymore, it just gets stuck at the "gray" screen before that (I took a pic of what screen i'm talkin about). Then I accessed in console mode and removed all the compiz packages, tried dpkg-reconfigure gnome and gnome-core, then reinstalled the ati drivers, but the problem is still there.I don't want to reinstall the whole system, I don't think a simple problem like this is enough to do so, but sincerely I'm completly lost.

So I have this laptop with a busted battery, I'm trying to get it into some kind of headless server, media topbox hybrid.
First thing I want to do is being able to leave it shut (powered on) in the corner without having to interact with it directly.
I've setup ssh and vnc so to login remotely and do task, transfer files and etc.
However there is a little issue with the laptop lid down upon turning it on, it immediately goes into suspend when getting to the display manager, which is 'lightdm'.
I suppose this is the default setting for Xorg and as such my custom configs for KDE only kick in after I login.
Question is: I never seen configuration for default power management stuff being done in Xorg, is there some way to disable automatic suspension on lid down?
Another question is: After the KDE kicks in does it always replace power options? I have setup a xorg.conf file specifying dpms options but these don't seem to remain.

I created a new user with command useradd (as root) :
Code: Select alluseradd razer123
And then set a password with command passwd (as root):
Code: Select allpasswd razer123
No Error!
When I logged out and tried to login with new user, I coulden't! (even after restart!)
I looked into /etc/passwd :
Code: Select allcat /etc/passwd | grep razer123
result:
Code: Select allrazer123:x:1002:1002::/home/razer123:/bin/bash
There is no home folder in the path!

After fossicking around I can not find anything around that I can invoke in a terminal to configure settings in network-manager. The applet(?) on the task bar doesn't ask for a login, so options are grey/grayed out. The "program" in the applications menu is similarly grey/grayed out.
If it was a once off, then I suspect that it would be simple as login as root to start X, but I have a series of config files to edited each time of their initial use. also, there is the ongoing problem of vpn target switching.
woops; wheezy with xfce4 and everything is uptodate.

I removed my .gnome and .nautilus folders and .notifier file. it is working now. I do not know exactly which of these 3 fixed it but I hope this might help someone else!I have some major issue with nautilus which is preventing me from loogging in into my system which is kind of criticle this weekend.I'm running Squeeze with latest updates.
The problem:Today gnome gave some problems caus my taskbar was suddently gone. I couldn't get it back to i reinstall gnome-desktop and updated my whole system. At the update some yes/no questions on a blue screen asking me to restart cups etc had corrupted yes/no buttons. Weird character sets were shown. Well that can happen sometimes i thought.After reinstalling gnome i can't login anymore. My screen keeps flashing while it shows the loading icon of the mouse.Anyone got suggestions? I can't find similar problems on the internet, only problems that happen while already logged in. In my case the segfault prevents gdm starting!

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.

Before I ask I know what I'm asking is not recommended.
On Lenny It was possible to change the boot login to permit logins as root
I can't find how to do that since I installed Squeeze.
