I noticed that our /etc/shadow file is readable on a patch I released for one of our in house linux boxes a while back ago. Could they use it to gain access the root account etc? Our passwords are all MD5 encrypted.

View 5 Replies View RelatedI'm currently creating a simple sh file which will copy the contents of a certain directory to / directory. in my sh file:
Code:
cd "$DIR"
for i in *.*; do
sudo cp -iv "$i" "$DEST"
done
but this requires user password. can i add the user password in my sh file? how? I'm trying to do this because I have an application to run the sh file and the application has no way to enter the password..
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
View 4 Replies View RelatedStumped 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.
is it considered standard practice to change the user password on a regular basis and if so how often?

View 12 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.

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

View 1 Replies View RelatedIn the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?

View 1 Replies View RelatedI'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.
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?
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.
Is there any way to view the any user activity/ commands history and date, time in the system? I look at the /var/log/secure but I can find only the login/ logout attempts and "history" command doesn't come with date/time that the user issue the commands. Any there any best practice to audit the user activities inside the system?

They don't have physical access, there's nothing on the computer itself and the person trying to hack has skill so I'm thinking like monitoring a proxy somehow, using the ip address somehow, compromising the modem in some way, possibly having access to google account etc. I am new to ubuntu and have really dug it so far but I want to figure how this is/was being done
