I tried to create a user on Solaris 10 but when I try to login the user with "su -" I get the error message "no directory". When I try to login with "su" I get the error message "no shell".
I tried the useradd several combinations e.g.
All the tries i made didn't work. I also checked the permissions on /etc, /bin, /sbin and / and it seems ok so that the newly created user can access them.
I run ProFTPd with TLS authentication on my Debian Lenny server. My problem is that despite of the fact that my users connect chrooted, one of my friends had root privileges after logging in form a Macintosh and could browse the root directory, too.

On a new installation of Linux Red Hat server, I was adding new users from the list using "newusers" command. I did not realize that one of the users was "root" so this is what line I loaded by error (among other users) : root:root:1176:501::/home/circuser:/bin/bash all other users from the list (160 of them) got loaded properly. I still have valid root login that I could use, but I'm not able to log in as root anymore. If I log in as user and then try "su" or "su -" I get error: ": No such file or directory".
I compared /etc/passwd, group and shadow on this server with old one I'm replacing and entry for root looks the same:
root:x:0:0:root:/root:/bin/bash ( in passwd)
root:x:0: (in /etc/group)
root:$1$OILC.ETm$LkoGprgqqgv6v8oLRUBnf.:15153:0:99999:7::: (in /etc/shadow) - similar to my old server
i just installed linux mandriva 2009. i set password for root and created a user account. when i try to login as root, after logging out as user, it does not allow me and gives the error "root logins are not allowed". even it does not show the root account. if i try to go to root from konsole terminal using su root, it allows to enter as a root but when i try to start the GUI with startx it gives error.not sure what to do and why i can't see my account in GUI mode
View 5 Replies View RelatedI was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

I doubt that this is what was needed (as I had that already when it didn't work, but I might be required in addition to installing dmraid)
# update-initramfs -a
After installing this, the problem was solved!! This is strange since I don't recall uninstalling this package or changing anything important, for that matter (perhaps did apt-get upgrade, but that's about it!). [URL]
Is there an easy way to prevent the logging of commands run into syslog as post-shell expansion?
I.e log a command of "ls *.log" as just that, rather than "ls a.log b.log c.log d.log" It makes rather a mess of the log files.
I am pondering on what would be any implications in logging in via SSH as root?Surely SSH is safe or am I kidding myself and falling for the unwary ethic of logging into a remote Linux box as root?I discovered some open ports remotely on the linux box, and decided to login as root to edit a configuration file to shut off the ports, hence my questioning in whether logging in as root...another point, since SSH is 'supposedly secure', there should not be any implications or am I kidding myself!??? Would it be better to login as normal user then su from there?
Ok, to make things even more interesting, what if its a bog standard generic linux distribution with no suid programs etc, then what happens...take that out of the picture, and say, for editing a configuration file...hackers are not going to see that are they, otherwise by the sound of the answers, it is putting an impression that hackers can see the traffic the minute you login as root?! Otherwise why bother using SSH? I mean, surely, SSH was designed to replace telnet and thereby increase protection...as we all know back in the early 90's before the internet became publicly available, that there was indeed sysadmins dialing in to private networks or telnet'ting into a remote system as root....
I have created a linux machine and installed some softwares on it with root user privileges . I used to login with root user credentials for doing the various task.
Later i have realise that this is not the best practice to follow and there should be a new user with less privileges to be created for doing the day to day task.
I have read the steps to create the user but will that new user sufficient enough to do the task that i m doing it through root user?
Will my software allow the new user to work on them?
I would be glad if someone points me to a guidelines on what should be my next step?
What are the differences between "su -" in a GUI terminal and directly logging in as root in a text mode terminal (tty1-tty6)? Any environment, path or other functionality differences?
View 14 Replies View RelatedI have a machine which has only /opt with some decent amount of space where I can install a software. /opt belongs to root:root. The software I want to install cannot be installed as root user.
So lets say I create a directory called /opt/install1 and then chown -R install1 to belong to user1. And now I install the software under /opt/install1 with user as user1.
Is this a best practice violation? There could potentially be just /opt/install1 belong to user1 and in future everything else created under /opt belonging to root..
I have a CentOS dedicated server running ProFTP. I have created user accounts which are meant for FTP access only but the users cannot connect to the FTP unless their shell access is /bin/bash
Here is an example line that is outputted when I use this command:
This user can access the FTP fine, but he can also access SSH which I don't want to allow him to do. If I set his shell access to /bin/false then he can't connect to the FTP.
What can I use in instead of /bin/bash to allow FTP but don't allow SSH?
Someone gave me a script that would tar then gzip my music directory, as well as remove the previous days backup. I have it set up in crontab, but it appears to have stopped working the last couple days, so i tried running it manually. Below is the script and the output I got. Any ideas why its failing now? I don't think anything changed on the server, maybe someone installed updates but idk why that would affect this.
Here's the musicbackup.sh script code...
I'm attempting to mount a Windows dir to a mount point on my Linux VMWare instance running on my Windows 7 machine. I am using a shell file to automatically mount the directory I want at bootup. However, I'm finding that Linux always mounts to a directory at the top of my C: file structure for some reason, and I can't figure out why.
Here's the dir structure:
C:/target (don't want to mount this, but this is what gets mounted)
C:/Users/me/target (this is what I want to mount to)
Here's my shell script:
Code:
mount.cifs //192.168.56.1/Users/me/target /mnt/target -o credentials=/root/credentials.auth,domain=mycomputer,uid=1001,gid=1001,rw
And here's what I get when I enter mount at the prompt:
Code:
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/sda1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
If this means anything my Virtual Machine has a single hard drive SCSI, which I believe is /dev/sda1. I don't see anything from mount that would indicate that the c:/target dir is getting hard-mounted somehow from the /etc/vfstab file, but maybe I just don't understand how mounting works...
When I try to launch application which runs in another window (not inside shell), it always fails with this kind of message: (example from gnome-terminal)

Falling back to non-factory mode. Failed to summon the GConf demon; exiting. Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon.

In composing a simple shell script in class, we can't seem to get the script to execute fully. script was formatted as follows.
#!/bin/bash
echo "good bye for now"
exit
did, Chmod 755 to make executable
type file name "bye"
runs but wont exit.....
it just echos the type"good bye for now
The instructor says it works for him at home....
But it wont work in class...
Is there a reason it wont "exit" the shell as commanded ?

Possibly related- 10 days ago, my smtp server was breached as a spam relay. The username they cracked was deleted. I added fail2ban for postfix. The logs show no further intrusion.
I wanted to know is there any way to monitor (I mean log)all of the activity of the users that logging in a server (as root) for example:
1.when do they logging in
2.what commands do they use at what time ( I know that history command do somehow the same but it does not save all of the activity of users exactly with the time of that activity)
3.which one of them installed which package on the server
4.what did they copy or move at what time and summery all the activity that each of them do on the server individually.

View 5 Replies View RelatedIt is possible to check who logged in with "who" command. If we are also logged in to that linux pc.
But, is there any possibility to check without our login?(not even by ssh)
Our logging in to find that pc, will be wasting the cpu resources. And may disturb the user who is working on the x-session.
regarding the file permissions of /etc/passwd in fact it has permissions like rw-r--r--so it says others have only read only permissions but my questions is if others has read only permissions on /etc/passwd file.how they are able to change their password i.e others are able to change their passwords then how it is possible.
