Fedora :: 12 Cannot Log In As Root, Cannot Su Nor Log Into Bash
Jun 22, 2010
i have an asus p5kpl-am se g31 socket 775 mobo with an intel pentium e5300 2.6 ghz cpu.
i think my problem might be with authentication or permissions possibly in pam.d, but i can not login as root, canot su, nor sudoer. i can't even use bash because i can't enter my password because when i enter characters the cursor just blink but doesn't even move.
i've tried re-installing. i've checked the configuration of the keyboard, but i'm limited without root access to some files.

One of our Fedora 14 machines has the root user stuck in bash. This would not be a problem as we rarely use root, but some of our processing runs on cronjobs from the root account. Tcsh is installed and up to date. All other users can switch shells except root. I do not know what happened as I was out for a day and came back and the processing was not working.

I need to launch a bash file in Linux from an unprivileged user session, file that will run bash commands as root. But I do not want to create an user with root privileges to do that.

Output of my #alias command looks just as normal as one would expect:
Code:
alias +='pushd .'
alias -='popd'
alias ..='cd ..'
alias ...='cd ../..' .....
And still whenever I (as root) type in bash
#ll
which would be short for
#ls- l
i get output of the command
#ls -al
So where aliases for root overwritten? Usually I would expect .bashrc in the /root directory. Or at least .alias file. But there none of those in my current /root. So, my question is where root user gets it's aliases from? This concerns only root user. Normal user has .bashrc and I made up my own aliases in .alias and that's works jut fine. And yes I could make .bashrc file in the /root and .aliases where I would define my own things.

I am trying to write a script that will create a directory, copy files to it, zip them, move the zip file to the desktop and clean up.However, when I run the script, it comes back stating that I do not have permission to make the directory. I wanted to know how to add the permission into the script to allow for access to whoever runs the script to pull the logs, but won't leave the system in the root user?here is what I have for code so far:
#!/bin/bash
host= 'hostname'
mkdir /home/savelogs

Basically when I comment out installroot it says grep and bash are installed but when I change installroot it says grep and bash are not installed?

[user1@localhost ]$
Now when I type su and want to switch to root account , it fails
[user1@localhost ~]$ su
Password:
su: incorrect password
[user1@localhost ~]$ exit
I know the password is 123 & I m 100% sure .

I have a bash script that I am using for doing tape backups. The meat of the bash script is
sudo tar --totals -H pax -cvf /dev/st0 *
This all works just fine.
But of course tape functions have to be ran as root, therefore sudo, requiring the standard user to enter the root password. I would like to be in a situation where the standard user does not need (does not know) the root password. I think my solution is add that standard user.
User named dog to the sudo list.
I have reviewed the sudo man page and looked at [URL]. I am still fuzzy.
1- Will adding user 'dog' to this sudo list do what I expect meaning I can run:
sudo tar --totals -H pax -cvf /dev/st0 *
and the user is not queried for the root password
2- How do I do that? and do I make a cmd alais for only: "tar --totals -H pax -cvf /dev/st0 *"
My distro is OpenSuse.

I wrote bash script that uses zenity and a choice to install various programs, tested it and it works, but only when I call it from terminal. I wanted to add it in gnome main menu. The script is /home/eee/zenity.sh. In accessories I added an entry with command:
Code:
/home/eee/zenity.sh
, but since there is no terminal it starts zenity, but it does not work. I have also tried
Code:
gksu gnome-terminal -x /home/eee/zenity.sh

the terminal and logged in as root i was changing file permissions and happened to change the root folder to 700. Now my icons have gone and i can't even access the terminal.
I was just wondering if it is possible to go to rescue mode using the cd and restore all the appropriate file permissions to root/ users if possible

I've started to get emails that would typically come from [URL] as [URL]. These emails come from services that send out emails (backup programs) directly, or from cronjobs. I've logged in as the non-root account and either sudo su - or su - to root and the restart the service at one point or another. If I login directly as root and bounce the service or cron the emails come across as from root. I don't see anything in my environment variables after I su to indicate what would cause this. I'm not sure where else to look? A pam setting? This seems to have happened between Fedora 10 and 14 (did a bunch of overdue upgrades recently) I've only got Fedora so I don't have anything to compare to. In Fedora 10 I did not have this problem.

I found this on Bee's website. For more info on this exploit there are links there:[URl]..All you have to do in Fedora 13 is enter the following lines in a shell as normal user:
[Code]...
I don't think this can be considered solely an "upstream" problem, because I first tried it in Arch using the same version of glibc, and the final command causes both gnome-terminal and xterm windows to disappear.

below are the details of my system. I have bash as my current shell, some really common commands aren't working.
Do I need to do a re-installation of bash? Or how do I install a selection of bash commands which I need? (for example a subset of [URL])
Code:
root@sdptfw:~ # uname -a
Linux sdptfw.sdpt.co.za 2.4.36 #1 Tue Jul 22 13:13:24 GMT 2008 i686 i686 i386 GNU/Linux
root@sdptfw:~ # echo $SHELL$
/bin/bash$

simple bash code:
Code:
#!/bin/bash
trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"
for ((i=0;i<5;i++)); do
[Code]...
How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?

I have searched and searched and maybe I don't know how to articulate this issue with out just posting the problem I'm having. Every time I bring up a terminal window I get the following "Header"
declare -x COLORTERM="gnome-terminal"
declare -x CPLUS_INCLUDE_PATH="/usr/lib64/qt/include"
declare -x DBUS_SESSION_BUS_ADDRESS="unix:abstract=/tmp/dbus-xSFd6zqrYQ,guid=dc5e07974559da016842742900000090"
declare -x DISPLAY=":0.0"

To be honest I cheated and used the .bashrc / .profile files from Ubuntu and all was working fine for a while now and it seems something changed to cause this... any ideas on why I am getting this? I checked my .bashrc and my /etc/profile and it doesn't look like anything is amiss..

I have winbind Active Directory authentication set up on my laptop. AD authentication works like a charm, passwords cache, etc. I can use sudo with no problem. However, I cannot use the root account -no matter what I set the root password to, the system will not take it. I also have a couple of normal system users (not winbind), and no matter what I set their passwords to, I cannot login.

This gives a selection menu where you choose an option, and it should continue. I have several of these as part of a much larger script, but something is wrong with this while loop.
Code:
VARIABLEINPUT="1"
if [ $VARIABLEINPUT == "1" ] ; then
echo -e "${YELLOW}How often would you like the automatic update and maintenance to occur after the installation?:
${RED}1)${WHITE} Hourly
${RED}2)${WHITE} Daily
${RED}3)${WHITE} Weekly
${RED}4)${WHITE} Monthly
"
[Code].....
A very simple loop that uses a variable from earlier in the script to adjust variables for later in the script. For some reason, this while loop will not end - I've noted where with echos.

I wanted to change my $PATH and my prompt, had some trouble with setting and exporting the variables and found that the shell was csh instead of the bash which I expected. I worked around it by creating a .cshrc which calls bash but don't know what caused the change. I've got as far as seeing that the gnome-terminal command kicks it all off from the Applications>System Tools menu but what happens between there and the terminal popping up?

I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.
