Ubuntu Documentation > Ubuntu 9.04 > Ubuntu Server Guide > Security > User Management states that there is a default minimum password length for Ubuntu:
Say the password is to be modified by the user using passwd. Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)?
This is rather than examining various places that control the policy and interpreting them since the process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.
After Days of trying to install Nagios, I eventually got everything working fine ! The only problem now is I get the following error message on the nagios web interface: "It appears as though you do not have permission to view information for any of the services you requested... If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI and check the authorization options in your CGI configuration file."
After installing Slackware 13.1, I find that I am getting the message:scripts should use an informative user-agent string with contact informationwhen I access certain websites. Wiki pages, for example. This happens only with Konqueror. Any ideas as to what I might change to gain access to content,
I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info /home/user1 disk usage /home/user2 directory info /home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
I just updated some user account information on my server and when I log on from a client it the ypcat passwd command shows the old info. How do I make it update? A related question... my NIS users can only log in on client machines using the terminal; it doesn't work at the graphical login screen. Is this normal? I'm new to NIS (just set it up last night) and still getting this stuff sorted out.
i'm trying to use the database that was used by vpopmail and vqadmin with postfix and dovecot. By setting up dovecot to use mysql, i can query username and password for authentication but how do i create a user and edit its information in the database? Poastfixadmin only use database that was created along when installing it.
Any viable option aside from recode postfix to meet my criteria?
I use tomcat as my server platform in Ubuntu for a war file. I know in order to get real time information about how many user are logged in, we can count how many active sessions exist by a SessionCounter code. However, I have to permit HttpSessionListener in web.xml of tomcat. From other users' experiences, the configuration is complexed and has some errors.
Here's the link:
In order to get users'ip, in jsp, use request.getremotehost() or request.getremoteaddress() by editing the jsp file. I wonder if there's some open source software to use for these two purposes.
Back in the old days of PC-DOS 3.1, computers are much simpler than today's. I can learn a lot of how File System works with tools like PCTools, Norton Disk Doctor, and [URL]. Have been working exclusive in corporate database application area for over a decade, my knowledge of how these stuff work is diminishing. Standard-clean OS (Windows, Linux) installation is all I can do now. And it starts to cause me many data-loss troubles, when I have to perform something that I don't have much insight, such as install and remove peer linux os or move and resize partitions.
I'm looking for books, web resources, or communities where I can educate myself on how various file system works, for which I can have in-depth answer to questions such as:
How to remove ubuntu and grub2 ? (I recently did that, but with a lot of frustration when I was not really sure what I was doing and confront with some scary error message like "Missing BootMgr" What kind of disk-partitioning operation can be performed non-destructively, and why ? What is Active partition ? Primary Parition ? Extended Partition ? How it stored on the disk. There are many free partitioning tools out there, which one is safe to used ? NTFS, Ext3, Ext4, .. What the differences ? How to choose it wisely.
I wanted to set up Computer Lab. loading Fedora 11 OS and one system acting as a Server to store Users(Student) Login Informations. When students do a programs, all programs (eg, C++ programs) files should be saved in the local fedora system but when login to the system, the login should be validate by a Server System.
I want to write a shell script which will simultaneously collect OS user information and write in an individual text files.Can anyone tell me the syntax of the script.N.B. The user name will be mentioned in an array within the shell script.
building an install cd or dvd media that will automatically install the Linux software on a client pc. There is no network connectivity so the client can only be loaded with Linux from CD or DVD media. The crux of the matter is that I can not automatically install the Linux software on client WITHOUT typing linux ks=cdrom:/ks.cfg at the boot prompt.
I want to avoid any user prompts and just have the software install with the RPMS that I need for this client pc at the boot prompt. Actually, when the boot prompt commences, I would like the software install to start with no user intervention. I've tried several different methods in isolinux.cfg, but the OS always wants boot prompt for the cdrom. Can the boot prompt information be read automatically from the isolinux.cfg with out user intervention? I'm looking for the same behavior as a LIVE CD that kicks off with no boot prompts after a few seconds. Here's a copy of my isolinux.cfg
default linux prompt 1 timeout 600 display boot.msg F1 boot.msg F2 options.msg F3 general.msg F4 param.msg [Code]....
I'm trying to write a program which would get information from a webpage and display the information on my desktop sort of like a widget. I kind of remember there being something like this already made, but for the life of me I can't remember what it's calledDoes anyone know?
When trying to install 11.2 from DVD, the user information I entered at the beginning of the install gets lost. I get to the Automatic Configuration step at the end of the install where the computer needs to reboot, and it asks for my user ID and password (it shouldn't do that). It won't accept the user I created (always says login failed), but it will accept root. That really doesn't matter, because the Automatic Configuration step has done anything, and I have a busted install. I've tried the install 4 or 5 times, but it is always the same problem. I eventually reinstalled 11.1 without any problem (though I did have to click Use Entire Disk on the partition section so it would delete the ext4 partitions created by the 11.2 install and create ext3 partitions).
Take a physical user FRED. FRED is a linux user ( known by linux on his laptop ) FRED is a Samba user ( Known by samba on the samba pdc server ) When he logs locally (with username/password) on its standalone laptop (with no network), he is known as FRED:user. He access his data in /home/FRED/. When he logs through samba (with username/password) on the domain MY_DOM, he is known as MY_DOMFRED:MY_DOMdomain user. He access his data in /home/MY_DOM/FRED/. ) Is it possible that the human FRED has only one repository and have full access to its repository regardless of how it was connected. If yes, how to do it
2) If not, Is it possible that the human FRED has full access to /home/FRED/.............. and /home/MY_DOM/FRED/.
I was wondering if it was possible to hide the File Systems from a user. So when then browse through folders or choose to save something the default folder is their "home" folder. I am using SAM Linux distribution and don't want my users to be able to screw anything up! I use thunar as my file manager and was just wondering if it is possible?
I switched to ubuntu around two months ago, and I'm loving it, everything I could need and more in an OS. I've just recently stumbled upon a problem; I tried to add Playdeb.Net's source URL and this came up on my Update Manager window; "Could not initialize the package information. An unresolvable problem occurred while initializing the package information. report this bug against the 'update-manager' package and include the following error message: 'E:Malformed line 62 in source list /etc/apt/sources.list (dist parse)'" package and include the following error message:
I have a question that i want to make a normal user to execute the commands which the root user is able to execute, say if i have a user named siru and when i logged in using siru i cannot run commands like tracert,nmap@loccalhost and all but i can run when i have logged into root account so my question is how to make siru to run the command tracert,nmap@localhost.I have even edited the .bash_profile of siru's home directory from
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then
I am trying to login to a redhat server via VNC. This used to work until I reloaded the box. Although I had previously logged in directly to the box, then I could vnc to it remotely. The service is running, netstat states the ports are open and listening.I can ssh to the box, and ran the usual commands to start the services.So my question is. Do I need to have a local user logged in before I can VNC, if so how can I do that via the command line.If this is not required for a local user to be logged in, what am I missing. Other than VNC, which other services do I need to start.
I have 389-DS ( Fedora DS) setup on CentOS 5.3 and working fine. I configured LDAP Client and want to login as user created under fedora DS Client. From Client Machine, I can easily see: Code: [root@fedoraDS-Client ~]# id ajrain uid=569(ajrain) gid=569 groups=569 context=root: system_r:unconfined_t:SystemLow-SystemHigh
This is User from LDAP Server (fedora DS Server) which is showing in Client Machine. So It means its retreiving value from Server. Correct? Now When I am trying to login , it says "Server unexpectedly closed network Connection". When I supplied user password: Code: login as: ajrain ajrain@fedoraDS-Client's password:
The File /var/log/secure says: Code: Jan 27 02:39:27 localhost sshd: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.210.53.104 user=ajrain Jan 27 02:39:27 localhost sshd: Failed password for ajrain from 10.210.53. 104 port 1241 ssh2 Jan 27 02:39:27 localhost sshd: fatal: Access denied for user ajrain by PAM account configuration
Is possible to send a message (popup window or something) to local user logged into X (xdm, fluxbox) from console ? For example: user1 is logged and using X/fluxbox, user2 logging into the same box by ssh to console. Now - what user2 have to do to send message to user1 ?
