I have a quick questions about MD5-sums in the /etc/shadow file:
One of our third party software products have created some new system accounts on our RHEL servers like this (sysuser is the system account, while user1 is a regular user account) code...
My bose ask me to convert a CentOS system password like "LMPQSMTE0nHlQ" to postfix MySQL MD5 Hased password, I find CentOS seems has 2 kinds of password form, one is shorter and the other is very long like"$1$C2MSk16n$WT5JWnzYH7XpCCjsiE2bd1", however I find postfix is exactly the later long one, so does any one know how to convert the short form to the later one

I have configured a FTP (VSFTPD) Server in RHEL 5.6, which resulted me a default directory /var/ftp/pub. Even i have cerated another Directory /var/ftp/accounts. Where Accounts Directory is owned by user x in my server. I have a issue with this, It prompts me User and Password while accessing this ftp 192.168.5.20 in Linux Servers. But while i am trying this through a windows machine by ftp://192.168.5.20 it gets directly accessed without prompting me any User and Password.
I need to have FTP environment same like windows. where it must prompt me user name and password, and i must be able to upload and download data from my windows clients.

View 1 Replies View RelatedMy goal is this: Allow a user to connect to a server via SSH with any login name or password without checking to see if that account exists on that server. Their account would be captured by a universal account say, 'generic_user', and then they would be directed to one of my python scripts with the username and password they supplied for initial login. At this point my script would capture their SSHD process ID and allow/deny their existence based upon a MySQL/Subscription check.
The part I'm having trouble with is with PAM and allowing the user to login with any credentials and be successfully authenticated under the generic account. Beyond that, everything is great.

View 1 Replies View RelatedI started to work on building a ftp by vsftpd in our lab (that's only for our lab members). I am going to setup some the virtual users for each of the member. We have a CentOS5 (without upgrade after the fresh installation). I try several ways to setup the vsftpd for virtual users. 1) with db4 2) with mysql 3) without database and use htpasswd. But all fails. Actually, I don't want to use database, so I am going to find out the reason of failure on 'htpasswd' method
My vsftpd is installed in /etc/vsftpd (for only using ftp account, it is no problem to login).
1) I setup an account called vftpuser and build the corresponding home (/home/vftpuser), and then I setup another account call usera and also create a directory within /home/vftpuser.
2) I use htpasswd to add passwd to usera and store the passwd in /etc/vsftpd/passwd.
3) I added the name of usera to /etc/vsftpd/user_list
4) I create a directory /etc/vsftpd/user to store a unique conf for each user (for usera, the conf named usera) which contains the local root for users, which is

I set up a servber on my local machine, & also PHp - Both working fine.I'm trying to load up MYSQL i have installed it, & *can* start/stop the server. however if I do anything else with it, I get this error :-
Quote:
root@gordon-desktop:~# sudo mysqladmin -u root -h localhost password MYPASSWORD
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
Query :-
1) How do I know MYSQL is actually active ? (apart from the message it says that its statrted (or stopped).
2) Is there a way to
a) Find out the usernames that are recorded on the MYSQL server ?
b) set / RESET the 'root' username (I know MYSQL root user is different to PC root user)
c) anything else I can do on the PHP / website code to see if MYSQL is working
(as yet, no tables / databases etc have been set up - as I can't get past this error message - I get the same error when setting up a database.)
Ps I did allow my usermname (when logged in to ubuntu) to edit / create files in the /usr/www/ directory (but it is still OWNED by 'root' - that directory)
i changed my password and whenever i log in i get a message that ur login keyring password and user password do not match, so how do i change my login keyring password!!

View 2 Replies View RelatedAt the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

I just did a fresh install of 11.4
My system auto-logs in and I know there's a bug in seahorse that doesn't like that method.
Anyway, I tried to unlock my "Passwords: login" in seahorse, but it won't budge.
The details about this user are that I re-used an 11.3 /home/$user directory. Could that be the reason?
I logged out of the Desktop and back in using my password manually.
I can sudo with my password. I can change the system with my password everywhere except in seahorse.
The password is exactly the same in 11.4 as it was in 11.3.
The .gnupg/ directory is 600 and its contents are all 600 except for agent.info which is 644.

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?
