I'm in debian trying to install passwd. It's giving me a heck of a time with shadowconfig, because that program tells me what's wrong but doesn't fix it for me. Basically it is saying that there are a lot of entries missing from my shadow file. So how do I add them? I don't want to have to do it all by hand.

The strangest thing happened. I installed Debian testing with the "squeeze Alpha1" netinstall cd. All seemed to go well and the installer made me pick a root password and create a normal user account. However, after the first boot my user account did not work and I could also not login as root, it looked liked I forgot the passwords for both accounts. When rebooted in recovery mode, I got Code: sulogin: root account is locked and I was automatically logged in as root without being asked for a password. Then I found out that the normal user account does not exist. I created a user acount and logged into it. I did passwd to set a password, but I got Code: passwd: Authentication token manipulation error Also, there was no home directory for the new user.
View 6 Replies View Relatedwe know that /etc/passwd - is a replica of /etc/passwd file and acts as a backup in any damage done to /etc/passwd file..i have observed a strange thing in RHEL 5.4....for example... if /etc/passwd has 100 accounts.. then /etc/passwd - is having only 99 accounts....when i add 101 useraccount with "useradd" then /etc/passwd has 101 accounts and /etc/passwd is having the 100th account of /etc/passwd - ..when i delete /etc/passwd and recover it with /etc/passwd - from runlevel 1 the lastly created user is not having his account after recovery.. what is the solution? this is same case even with /etc/shadow and /etc/shadow -
View 2 Replies View RelatedI recently set up a LDAP server, and have a server using it to authenticate users.
That works completely, but when a user tries to use passwd to change his password this happens.

And this is in /var/log/auth.log

I just installed Squeeze on an older PC. Installation seemed to go fine. But when it booted up on the installed system for the first time, I could not login - username/password failure. I tried every possible typing error and CAP LOCK error I could have made - still nothing.
I brought up a console window and tried logging in as root - same problem.
I booted into single user mode and entered passwd command to set new root password - I got a SYSTEM ERROR message from the passwd command.
I booted to a Live CD, went to /etc/shadow and deleted the encrypted password. Rebooted on the hard drive, went to console window and logged in as root, with no password required. So far so good. I entered passwd command to set new password and got the same SYSTEM ERROR message.
The machine seems fine when running on the Live CD, and the install seemed to go fine.
I'm trying to setup a LDAP server and it seems to have all gone pretty well. I set it so that users that type their passwords wrong 5 times are locked out for 20 minutes. That works fine, but if I want to log on as an admin and unlock their account before that 20 minutes is up it isn't working.Normally, (authenticating locally)
Code:
passwd -u blank888
works and does what I want it to. If I want passwd to recognize the LDAP server I use
Code:
passwd -D cn=Administrator,dc=example,dc=com -u blank888
When I run that, it always asks for the admin password like it should, but then will only work on some accounts and not others. Mainly I've seen that it only works on accounts that already had local accounts before connecting to the LDAP server.If I run a passwd -Sa command I will get something like:
blank888 LK 07/18/2011 0 999 7 -1
blank888 LK 07/18/2011 0 999 7 -1
test LK
blank888 already had an account on the machine, but also had a LDAP account along with test. So blank888 is showing twice because he has both LDAP and local accounts, whereas test only has a LDAP account. So now if they both get locked out passwd -D $adminDN -u $account will work for blank888 but not test. Then the results of a passwd -Sa would be:
blank888 PS 07/18/2011 0 999 7 -1
blank888 PS 07/18/2011 0 999 7 -1
test LK
I need to be able to unlock test using passwd. The LDAP server is running 11.2, and the hosts are running various Linux distros, and XP.Can anything think of a way to fix this without removing the LDAP server, adding local accounts for everyone, and then putting the LDAP server back on?
I read that passwd -S spits out informationabout a user's password including the encryption algorithm used to encrypt the password in /etc/shadow. I ran the command but nothing about the algorithm is returned. Is this a quirk in openSUSE?On another note, I've determined through other means that I've selected blowfishryption as evidenced by the $2blah$2blahblah format of the /etc/shadow entry. However, if I look at /etc/default/passwd it lists CRYPT=md5. If I'm using blowfish why would that variable be set to md5. onversely, if it is set to md5 why is the blowfish algorithm being invoked?

I noticed that the ~/.vnc/passwd file is empty, alongwith the log file. I typed vncpasswd to set the password again, but no use. I tried vncpasswd ~/.vnc/passwd as well, but no use.The VNC server is running.

When I set it to 644 as su, it eventually changes back.This occurs on my openSuse10.2 machine but not the openSuse 11.1 machine, but I assume that is irrelevant.

View 5 Replies View RelatedAll servers mentioned below run OpenSuSE, either 10 or 11.I am currently working on a few scripts that are meant to be used as part of a continuous integration setup. I am trying to keep these scripts reasonably secure, and so I have made sure that all the servers run these scripts only as a specific user (user1) that has permissions to basically nothing else. The problem I am currently running into is that I need to start and stop tomcat as user1 but this user doesn't have permissions to the tomcat rectory (only tomcat has execute permissions). I have a temporary workaround in place while I work on the scripts (I have an SSH key in place that allows me to SSH from user1o tomcat without a password and execute my commands that way) but it is not very secure. I have tried adding the following line to /etc/sudoers:
Code:
tomcat localhost = NOPASSWD: /opt/tomcat/bin/startup.sh, /opt/tomcat/bin/shutdown.sh

I do not need a centralised database just a login auth system.On the server I make a folder called /sec and symlink passwd, group and shadow into it.I export this via nfs.On the workstation I create a folder /sec, move the passwd, group and shadow file into it and then symlink them back into the /etc folder.On bootup, the rc.local mounts server /sec over the top of workstation /sec. If it fails it falls back.I wasn't sure if I could just mount /sec on the workstation and then temporarily symlink group,passwd,shadow over the top of the /etc/shadow etc

View 2 Replies View Relatedwe are trying to make a policy decision whether to go with SSH user/passwd or PPK secure key ? our servers are hosted remotely by a hosting service. we were wondering which of these two models are more secure.e.g. i would tend to think that user/passwd with account lockouts upon failed attempts would be more secure because the other option exposes your server in case someone sneaks the PPK file or steals your whole computer.however, what makes me doubt myself is that Amazon Web Services EC2 cloud hosting uses PPK by default (although an instance's SSH config can be change to accommodate logging in but they don't endorse it).
View 3 Replies View RelatedI need to either locate a script that is similar to what I am needing or figure out a better way of doing what I need. I have mutiple shops with AIX unix servers, using ksh with virtual terminals that connect. since these are on an internal network we have them connecting to the server as either usr01, usr02, etc. what I need to do is add 15 user's ranging from usr01-usr15 into /etc/passwd each usr is identical in such that each line contains
Code:
usr01::0:0::/usr/tops:/bin/ksh
only difference is the usr# changes. I wrote a script where I was just adding these all to the /etc/passwd but now I have been tasked with adding them to these shops but with out any duplicates. is there any way to have a script check the file to see if the usr# exists and if so proceed to the next number and then input the usr#::0:0::/usr/tops:/bin/ksh into the file?
