CentOS 5 :: Recover / Reset Password For Root Via Single User Mode

Oct 20, 2009

Can someone assist me with recovering/resetting the password for Root via Single User Mode in CentOS v5? I've modified the kernel line using Single, S, and 1 but it appears that these commands are being totally ignored as the server continues with the boot process and displays the GUI logon screen. The server in question is a VM box running on ESX v3.5 U4. The person that created this VM is no longer employed here and I've exhausted everything I know regarding Single User Mode.

Ubuntu Security :: Capture User Password On Login?

Apr 4, 2011

Second off, I'm trying to capture a user password on login (through gdm) such that I can re-use it for a service like Kerberos or AFS. The idea is that the user has to log in only once, and then I renew the tickets and tokens until they log out again. If there's a better way to do this

Security :: Sudo Non-user/non-root Password?

Feb 19, 2010

Stumped on this one. I'm trying to set up limited sudo authority on a desktop with some sensitive user data, and as an extra precaution I wanted to configure sudo to use a password other than the user's or the root's. I'm not sure how to do this. From the manual, we have a few options, such as "runaspw" or "targetpw", but none seem quite what I'm looking for.For instance, "runaspw" could be used if I created a user for nothing other than sudo(ing) purposes, but it requires you set "runas_default", which means that said user would have to have authority to execute said commands in the first place. This is workable, but seems like a lot of extra configuration for each specific command that I want to run, as well as creating some issues with simply commands such as "shutdown" or "reboot". Also, "targetpw" can be used in conjunction with a sudo(ing)-only user if I set an alias, but, again, this isn't quite what I am looking for.

Ultimately, what I am really concerned about in this situation are keystroke loggers, so I would prefer to avoid repeated entering the user or root password when performing administrative tasks. Also, I would prefer not having to create a sudo(ing)-only user as mentioned above to prevent a comprimised password resulting in an attacker being able to log into my system.

Security :: PAM Module - Allow A User To Connect To A Server Via SSH With Any Login Name Or Password

May 5, 2010

My 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.

Security :: REDHAT Missing Functionality - Force User To Change Password On Login?

Mar 16, 2011

I have now been trying to find an answer for the following for a while and can't seem to get anything.On previous linux distros we had the option available "passwd -e" which allowed us to force the user to change their passwords upon the next login.s functionality however seems to be excluded from latest linux distros (currently using RHEL 5.4)...Does anybody know how the same effect can be achieved and perhaps any idea on why this option was removed as it was great for securing passwords

Ubuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length

Dec 14, 2010

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.

And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.

Security :: NIS Password Mapping - Allow User "techsupport1" To Access Web Server?

May 19, 2010

I have a NIS server and a web server as a client. I have a regular linux user (without root privileges) "techsupport1" on NIS server.
On the client web server, I have root user, and my clients. Now what I want to achieve is, allow my user "techsupport1" to access the web server, but instead of logging in using root user, I'd like the client to use username "techsupport1", but in the same time, give that user root privileges on the web server (client). The reason, is that I have more than one user who need to manage the web server (client), so I want to be able to clearly see in the bash_history, who has been running what commands. right now, when I login as a techsupport user to the web server (client) from my NIS server

[code]...

I don't have root privileges, also my gid is matching to gid of a customer who has the same 517 on the web server. How can I configure, so when a tech support agent 1, logs in to web server, NIS grants root privileges, but keeps the techsupport username?

Security :: Getting Access Denied When "user Must Change Password At Next Logon" Is Checked?

Mar 1, 2011

I have got a RHEL 5.6 server configured to authenticate via a Windows 2008 domain controller via LDAPS.Everything is working fine, except from the following: When I create a new user in Active directory and check the option "user must change password at next logon", the new user cannot logon and gets an "access denied" message. In /var/log/secure, I find the following:

Mar 1 14:43:21 cpssvn10 sshd[5363]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.3.12 user=testuser2
Mar 1 14:43:21 cpssvn10 sshd[5363]: pam_ldap: error trying to bind as user "CN=CPSS Testuser 2,OU=IBM,DC=cpss,DC=smarterplatform,DC=com" (Invalid credentials)
Mar 1 14:43:23 cpssvn10 sshd[5363]: Failed password for testuser2 from 192.168.3.12 port 4583 ssh2

As soon as I uncheck the "user must change ..." option, the user can log on without problems. Also password change via the passwd command works.
