Fedora :: Can't Change Root Passwd - Even In Singleuser Mode
Feb 17, 2009
FC9 - Sulphur, x86, nothing fancy
Did an update (damn the unofficial repos!)
Found a problem with pam_passwdqc module.
Like the title says, I'm unable to change root's password.
I boot into singleuser mode, run passwd, get the
Code:
Boot into multiuser mode and I'm still unable to login.
Two questions:
1) Anyone have a 'default' /etc/pam.d/system-auth that I can replace with the system-auth that was obliterated by the pam_passwdqc update?
2) Any other ideas?

I have a web server running Centos5 on a Xeon processor with 2GB of RAM. Whenever I try to login as a user the system hangs.If I login as root I can login without any problems. I tried changing the passwd. I can change the passwd but still not able to login as that user. I tried creating a new user. When I run the command adduser or useradd the system hangs.

we 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 -

I 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.
Code:
And this is in /var/log/auth.log

The first time I started F15 the following notice appeared (approx.: I have translated it from spanish):
Quote:
Unfortunately GNOME 3 failed on having started and it is now in alternative mode. It probably signifies that your system (graphic hardware or controller) is not capable of executing GNOME 3 complete.
Computer data: AMD Athlon XP 2400+ 2,01GHz; 1.5 GB RAM; ATI Radeon 9200SE. Fedora 15.
How can I change from "alternative mode " to another more friendly not 3D desktop?

I have a Dell Optiplex 760 Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz
running:
I tried to upgrade to FC11 via download and DVD and in both cases the install hangs on bootstrap right after remounting the root filesystem in read/write mode.
Since it hangs in this manner, I have not been able to gather any logs...

How can I change the window focus mode in compiz in F14? I prefer point focus rather than click focus, but the 'system -> preferences -> windows' cannot run in compiz environment.
Also, can I save the position of the terminal in compiz? I don't want to adjust the terminal positions manually after each logging in.

I compiled a code on a Linux cluster machine with mpich and ifort. A test run shows that the program works fine. However, it seems that the program is running in serial instead of parallel mode: reducing the number of CPU's from 32 to 3 does not increase the time it takes to run the simulation. Infact, the simulation is slightly faster with 3 compared to 32 CPU's. Unfortunately I have very little experience on the subject.
My questions are:
(1) How can I be 100% sure my code is running in parallel and not in serial mode?
(2) If the code is running serial, what do I need to do to make it run in parallel mode?
Details:
For submission I use a jobscript which includes the following lines:
Red Hat 4.1.2-46

I got during my last year of high school, and I recently installed Fedora 11. During the installation, I misunderstood one of the questions, and set my root password as what I wanted my account password. I want to go in and change it, because it's pretty easy to figure out and has me feeling really vulnerable, but it won't let me. I went to System-Administration-Root Password, entered my password, and put in a new one, but it won't let me click Change Root Password. The button is faded out and unclickable. I've tried several different passwords, and triple-checked each to make sure I typed it in correctly, but it won't work.

after a fresh install of fedora 13 I was expecting a few niggles and here's one, I've googled and read man chmod and chown and there seems to be plenty of conflicting advice, oh yeah the problem, I installed a package called get_iplayer (allows downloading of bbc iplayer content) via yum, only thing is I can only run it as root whereas in f12 I could as a normal user. It's probably the simplest command to change permissions, also I can't find any info on what the different numbers mean (775 777 etc)

Yesterday I installed Fedora 14 on my computer. I was able to log in as root on a terminal fine until this morning. Now when I log in I get this:
Code:
[Silverback@Vanessa ~]$ su -
Password:
su: warning: cannot change directory to /root: No such file or directory
-bash-4.1#
I haven't deleted any files, so I have no idea how to fix this.

1. I tried to change my password by typing "passwd" in the terminal. It then asked me to input the Unix password. After I typed in the Unix password, it read "Authentication token manipulation error". Why did that happen? I know what the Unix password is.2. . What is the difference between Unix password and Root password?

Get Fedora 11 and Apache installed. Open web browser and enter http://localhost and I get a "Fedora Test Page" that shows Apache is working (according to the info on the page). It says to put my web documents in /var/www/html/ ... however, as a user I cannot access it (put anything there) and I can't change the permissions (belongs to root) I'd like to run this as an intranet web server in our small ( <100 users) company.

I wanted to know is there anyway we can change the document root location /var/www to some other custom location. I tried modifying this location information in couple of conf files in /etc/httpd, but I started receiving lots of error messages from selinux on labelling issues. So I had to revert back.
