Server :: Unable To Change Password At NIS Clients?
Mar 26, 2011
I have not got a chance to play with NIS enough except basic RHCE stuff. I have some CENTOS 5.5 boxes on which I have set up NIS+AutoFS All is working pretty well except NIS users can not change password at NIS clients. I am getting this error.
[vicky@box2 ~]$ passwd
Changing password for user vicky.

I have configured LDAP server on RHEL 5.2 Linux. Client is unable to change its password from client linux box. I think there is PAM configuration problem in /etc/pam.d/system-auth file. What will be the exact entries in this file.
I have tftp-server running on Centos 5. Clients which are on the same subnet as the server are able to get and put without problems. I have a client that is across the internet that is having trouble getting files from my tftp server. A tcpdump reveals that the client is requesting the same file over and over again. In /var/log/messages, I am see the following error repeated over and over until the client finally gives up.
localhost in.tftpd: tftpd: read: No route to host
I want to replace Windows AD with SAMBA I want to know what policies restrictions I can get in SAMBA as compared to windows AD - whether it is possible to restrict clients not to change IP, access cdrom or control panel.
I am using postfix as my MTA. It is running on ubuntu and I am administering the system through webmin, try as I might with different configurations, I can't send email from a client. when I look in the mail.log i only find:
Jul 26 15:31:00 alpha postfix/smtpd: connect from unknown[184.108.40.206] Jul 26 15:31:31 alpha postfix/smtpd: lost connection after UNKNOWN from unknown[220.127.116.11] Jul 26 15:31:31 alpha postfix/smtpd: disconnect from unknown[18.104.22.168]
I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains). The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
Someone hacked my CentOS 5.4 test box, that I run at home with a gnome interface. It is connected to a domain name, the hacker changed only the root password. How can I change the root password? I get a graphical Grub at startup and if I press "e" nothing happens. Is there a different way to have Grub boot in text mode? Remember that I don't have root access. I was thinking to use the linux rescue mode, but I don't know what steps/commands to enter.
hello i am trying to change my password, but when i type in the new password i get this:"The password is longer than 8 characters. On some systems, this can cause problems. You can truncate the password to 8 characters, or leave it as it is."my question is what kind of problem could i get and how can i change so i have to log in every time i start the computer?
I am using centos 5.3 and running a postfix mail server. Most of client have one common demand that they want to change their email password themselves. so Somebody suggest me how can i make the web interface so that client can change their email password from web.
My company has policy that user accounts expire once a month and they also get locked out if they re-try login more than 3 times (pam_tally). It gets very annoying every time they come and ask to get password changed.How do I let users change their own password? Also let the system email them every day for two weeks before password expiration and until they change their password?
I have configured Ldap Server in CentOS 5.4 & it's working fine, the problem is when I create a ldapuser from server the user can login in client machine but the user has no rights to change the password. How to rectify this by using commands.
How can I change the root password of MYSQL server. I have just finished installation, but I mistakenly typed the wrong root password, and now I need to change it from command line, because I cannot even access the UI.
I've configured more email clients over the years than I care to mention so I am by no means a newbie at this so when I set up linux for a friend recently (10.10 on a laptop) I came across this problem, the install went wonderfully btw! The fix, long story short, if you are a sky broadband customer and are just setting up your email, you'll have a letter informing you of your email address, you log on to sky.com/resetpassword (or similar) enter some credentials and enter a password. This worked fine with the webmail, log in no problem, configuring a client (Thunderbird and Evolution) resulted in receiving a login failure with the message similar to 'credential failure' or words to that effect.
So after entering the password again and again, reading and re-reading the sky.com site instructions on setting the correct security settings, checking the correct ports, checking the correct settings to allow an IMAP connection from within the webmail interface and still getting no where I did this: logged into the webmail interface, then 'mail settings' > 'accounts' > then 'google account settings' then 'change password', this opens a sky.com reset password window. choose the my security question option and use this to enter a new password and this worked.
I suggest not using the 'my email address' and 'send an email with a reset link' option, this was attempted first and resulted in the same issue, new password set for the webmail but still not working with an email client. It seems that, and I'll be corrected by anyone who knows for sure, that their software is currently not updating all the passwords held if you use the 'reset password via email link'and neither did the initial setting up of the password work correctly either. My best guess is the passwords are going out of sync with their email servers not being updated correctly in all circumstances. Once I had reset the password as described it worked first time, so clearly there is something in this.
For info the settings for IMAP:
outgoing mail settings:
[URL] security: use name and password connection security: use SSL port should be set to 465
I work on a product that have to start automatically an application. Running Opensuse 11.2 So in the inittab I have : 1:2345:once:/root/Velox/VeloxBoot.sh 2:2345:respawn:/sbin/mingetty tty2
In the VeloxBoot.sh, if I don't press any key, my application starts after a timeout. If the user presses a key I want to have a login prompt. Unfortunately, if I start /bin/login, I have a prompt with login, but once I enter my login, it does not ask for a password and it says wrong password
I'm really new to Linux so this will probably sound like a pretty naive question to most users, but how do you change the root password?To install Java, I have to type # su into Terminal,which then asks for the password.What's weird is that when I start typing a password, no characters show up. I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.
I have a brand new install.I was doing some housekeeping and made a more sure password.Something went wonky and I got locked out.So I booted to root and changed the password.I'm back in the box now.But, my keyring password no longer matches my user password.So every time I want to do something I am asked for my old password.How do I change my keyring password to match my login password?
How can I force passwd to use a simple password?I want to change my passwd & delete passwd history (if stored).I plan on creating a Virtual Appliance that uses another password besides my testing password.
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.
