We have installed the Centos on server. I have enabled the ssh key authentication in that server. Now we can connect through ssh only with key file.Since this server is protected with SSH, I am unable to use the SCP command. If I use this command it says "Permission denied (publickey,keyboard-interactive).". Please let me know How Can I disable SSH Key or why SCP command is not working ?

I set up a debian lenny in vmware on my windows machine. The network interface is set to bridged, so the virtual machine is connected directly to the university network i am connected to. I want to be able to ssh into the vm.I installed sshd via "apt-get install ssh", generated a key pair with puttygen and copied the public part to "/home/user/.ssh/authorized_keys", set rights to 600 and then tried to disable password authentication completely, following the "securing debian" documentation.this is how my /etc/ssh/sshd_config looks now:
# Package generated configuration file
# See the sshd(8) manpage for details
# What ports, IPs and protocols we listen for
[code]...
Is there a way to disable password authentication completely? The command line is the following:
ssh -o KbdInteractiveAuthentication=no -o PasswordAuthentication=no machine"
it STILL asks for a password. Of course I would like to do this without touching the server, if possible.
I have a problem with ssh.I followed this guide:and no matter what I try, I still can't disable password authentication. I want users to require a private key to prevent from brute force hackers.

View 5 Replies View Relatedhaving a slow internet connection, I bought the all maverick repository on DVDs, copied the files on a usb drive and modified the apt sources file to consider the local repository only:
Code:
# deb file:/var/www/ubuntu_local/ ./
deb file:/var/www/maverick/dvd1/ maverick main universe restricted multiverse
deb file:/var/www/maverick/dvd2/ maverick main universe restricted multiverse
deb file:/var/www/maverick/dvd3/ maverick main universe restricted multiverse
[code]....
Even though I am reasonably sure it is safe, this local repository is not authenticated and I can only install package through the command line or synaptic, the Ubuntu Software Centre giving an error message "Requires installation of untrusted packages"...I thus would like to disable the apt authentication check for this local repository.
I'm dual booting Ubuntu 9.10 and win7. I have an NTFS partition on my disk and whenever i want to browse files on that partition I'm required to enter my password. my problem is that my music folder is located on that partition, and as a result, whenever I open rhythmbox, it cant access the files on that partition and begins to remove them from the library. in order to prevent this i must browse to that partition manually and enter my password upon request, prior to opening rhythmbox.
on a side note - shouldn't the spell checker on the Ubuntu forums recognize "Ubuntu" as a legit word ?
So after tinkering for a while, I was able to configure ssh for private/public key authentication and disabled Password-Authentication. In the past I had some issues with people brute force trying passwords/usernames so I want to avoid this, but I need some form of secure FTP that now doesn't work due to the aforementioned setting.

What is the fastest setup to do this? All I want is an internally authenticated webmail server that other servers can send mail to for collection of test emails. Don't need LDAP or anything fancy, just a internal LAN only webmail server. I've got Squirrelmail setup on Ubuntu Server and can't get authentication setup with Squirrelmail and every tutorial I read is way over complicated or has nothing on how to authenticate Squirrelmail with internal, system users.

View 3 Replies View RelatedI need to make a choice on what authentication protocol I want to use for Authentication and Authorization. I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.

If users are a memebr of a certain AD group, they are granted access to the web. I have this working but there is a glitch. I have to restart squid everytime I add or remove a user from the active directory group for the change to kick in.
