General :: Sudo For A Single Command With No Password Entry
Apr 20, 2010I wish to allow a user to use sudo to run a single command (service app status) to determine if my application app is running, in my sudoers file i have: user ALL= /sbin/service app status I understand that there is a parameter called timestamp_timeout that will set the timeout for the 'user', but requires at least 1 entry of the root password.
I wish to allow the user to do "sudo service app status" and not have to enter the root password ever(maybe once is ok), but still make the user enter the root password for all other root activities. Is there a way to prevent the password entry for this command only and no others?
Fedora :: Several Scp's And A Single Password?
Sep 12, 2009I want to create a script in bash to allow me to retrieve some files I have in a cluster. Access is through ssh, and the command I use to copy files is scp. The problem here is that when the script is run it asks for the password three times (it is instructed to copy from three different folders).
It doesn't matter if I use
Code:
scp user@server.com:/home/user/FolderA/* .
scp user@server.com:/home/user/FolderB/* .
scp user@server.com:/home/user/FolderC/* .
or
Code: scp user@server.com:/home/user/FolderA/* user@server.com:/home/user/FolderB/* user@server.com:/home/user/FolderC/* it still asks for the password three times. Is there a way I can use scp that asks for the password once?

Apr 17, 2009Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.

View 1 Replies View RelatedFedora Security :: Suddenly Root Password Invalid For Su Command?
Apr 9, 2011I have recently installed Fedora 14 on a new computer we presented as a gift to my sister-in-law. She is new to Linux. Although I've used Fedora since Core 1, I'm no expert on security issues, and this baffles me. She's doesn't know how to change the root password, so why doesn't it work any more? She discovered the problem when attempting a yum update from a terminal.(1) How could the root password have gotten changed? How likely is it that someone got onto her system through ssh, made a lucky guess on her root password, and then changed it? Are there robots that do this?
(2) The firewall is enabled. I have it set up as follows: (a) under "Trusted Services," only ssh is checked (I need to be able to get in remotely this way); (b) under "Trusted Interfaces," I have eth0 checked (I need to be able to use VNConto her desktop).Question: Are these settings giving ample protection? What settings would be recommended to protect her system while at the same time allowing me to access it through ssh and VNC?
Software :: Password Command Doesn't Recognize Valid Password
Nov 23, 2010I migrated an old SuseLinux 10 box to Debian (Lenny) a couple months ago, and apparently no one noticed you can't change your password. Root can do it because passwd doesn't ask root for a password, but no one else can (although they can log in, passwd doesn't recognize their login password when they attempt to set a new password and it asks).I changed authentication to use blowfish when I setup the server (because the SuseLinux 10 system used it) and apparently the passwd command doesn't work with that. Apparently I need to update another configuration file or possibly get a different program to update the passwd file if I use blowfish. Any ideas?
The weird thing is that it can generate a blowfish hash to set a new password, but apparently can't generate one to authenticate the user.something changed recently and it is no longer generating a blowfish hash when setting a new password. It is generating a hash with only 13 characters. And I can clearly see that many users have changed their passwords.

Sep 1, 2011I have ubuntu 11.04 installed along side windows. And I often share files with windows computers. If I am installing a new package from ubuntu software center, and consquently I have to log in as root to do so, which means I have given the system 'privileges' as the program is being installed, I decide to go open mozilla, and surf suspicious sites on the net. Is it possible in that case for me to get a virus?
When we enter the password for the root user in order to run one program such as ubuntu software center, does that mean that all programs have root privileges for the time being (as the software center is installing the program)?
