I forgot the root passwd for linux (via the "single" mode) and, according to all confirms, did so successfully! I then try to log on to Centos as root, and I can't....it says "incorrect passwd"! So then I log on as another, regular, but not root, user, with that passwd, and boot up into Centos. if I try to "su" to root, with the new root passwd, again it says its incorrect. there is no "system admin" passwd set. I checked!. I need root access within Centos!

View 2 Replies View RelatedCan someone assist me with recovering/resetting the password for Root via Single User Mode in CentOS v5? I've modified the kernel line using Single, S, and 1 but it appears that these commands are being totally ignored as the server continues with the boot process and displays the GUI logon screen. The server in question is a VM box running on ESX v3.5 U4. The person that created this VM is no longer employed here and I've exhausted everything I know regarding Single User Mode.

View 1 Replies View RelatedI am an old Ubuntu user and have just strted running F11 on my iBook. I always run system-config-samba on all my machines including my server and even on my work server which shares with windows, Linux and OSX and have found it to be perfect. I installed it straight away on the new Fedora system but It doesn't seem to be functioning the way i expected it to.
I installed system-config-samba and then set up one share folder "Public" with open read write privileges and then turned off the Fedora Firewall all together. But "public" did not become open until I entered the user password for the fedora machine. But, then I could see all folders on the Fedora machine. Even root on the fedora machine became write-able on the network. This was not the desired effect at all. I am assuming fedora is using a non system-config-samba file share system that I am unfamiliar with. what is it? and how does it work?
I am currently working on a project related to packet sniffing which has been implemented using the concept of raw sockets. I am using C language.I am able to decode the following details from the packets received from a local network,like:
source and Destination Mac Address
source and Destination IP Address
source and Destination port no
But I am having trouble in decoding the domain name when an user in the local network is logging onto internet.For eg. if a user in the local network is trying to log on to web using his browser say if he has logged on to url then from the packet I need to get the following details
source Mac Address from which user had logged on
source IP Address from which user had logged on
domain name
At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

3. Distribute key to every node

I'm running a server with CentOS 5 where the software that needs to run on the server uses ifconfig to verify the system IPv4.The problem is that /sbin isn't set for the user that is supposed to run the software (sadmin) which means the software can't execute ifconfig and thus terminates.now the workaround I've been using is simply to input.
