Red Hat / Fedora :: SFTP - Using RSA Key Authentication - Still Prompts For Password
Dec 5, 2010
Server A: Generated RSA Key
Server B: Added the RSA Key to authorized_keys list
SFTP from A to B.
Still prompts for password.
I will be sftp-ing both from Server B to Server A and 'A to B'. Sever B to Server A works fine. No prompting for password. But from A-B it this is what is happening sftp -v log...
debug1: Offering public key: ~InfAdmin-.ssh-id_rsa
debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug1: Trying private key: ~InfAdmin-.ssh-id_dsa
debug1: Next authentication method: password
InfAdminATServerB's password:
Why is this trying id_dsa private key? From Server B to Server A when I do the same, it does not say 'Trying Private Key -id_dsa' This is what it says
debug1: Server accepts key: pkalg ssh-rsa blen 277
debug1: read PEM private key done: type RSA
debug1: Authentication succeeded (publickey).
How do I enforce that Server A does the same? Why is it trying the dsa private key when I have used RSA.

Tried right click desktop and nothing
Tried export TMOUT=3600 on a xterm account, not sure if it is working or not.

I am running Ubuntu 9.10. When I open Evolution, it prompts me for a password to the default keyring. I am not sure what this is, but I would like to not have to do this. I looked around in Evolution and did not see a way to have this password entered automatically. I searched this forum and it found no results. So I don't know if my problem is unique or not.

I know, I know, its a security feature. That doesn't make it any less annoying. I find the constant asking for my password to be every bit as irritating as Windows's UAC. When I want to use the terminal, or when I want to download something, I don't want to have to enter my password every time. I don't care that someone could theoretically do something to my computer in some way. I managed to stay out of harms way in windows with UAC off, I'm sure I can do it in ubuntu without the constant nagging of the password prompts. Its annoying and I am tired of dealing with it. Anyone know how to turn it off? I am really not looking for reasons to leave it on. Its the same with UAC: Yeah, it can keep you out of trouble. No, I don't want it on.

How to fix the problem that is happening with gksu. It prompts me for the administrative password. I don't (for advised security reasons) have a password associated with the root account.
The sudo works fine and accepts my sudo password. Gksu fails with "incorect password... try again." error.
This is a new install of the Ubuntu Server 10.10 x64 Maverick edition.

I just installed Ubuntu last night on a partition, and so far..There is one thing that may be a deal-breaker for me though: It seems that I am always prompted for a password!!!! When I first start my machine up...PASSWORD! O-K, once a day wouldn't be so bad...but if I let my display turn off while I'm away from the 'puter...I come back, and...PASSWORD?! Every time I try to do anything on the system....PASSWORD?!
I did a few things that I thought might solve the problem- I checked some boxes here and there, like "automatically log on" and made myself an administrator....but no matter what I do, I'm plagued by the password prompt 600 times a day and i can't take it!!!
Is there any way to stop this nonsense? This is WORSE than Windows UAC crapola!! (at least with that, you just have to click a button)- As much as I am loving Ubuntu....if there is no way to disable this password nonsense, I'm afraid I'll be heading back to Vista. I'm the only person who uses my computer (Although I think my dogs were playing on it while i was out fixing the tractor today...)- so I just need to know if there's a way to get rid of all this password-protected stuff?

I have a standard home set-up for my Ubuntu OS, and I would like to know whether its possible to cut out the repetitive prompts to enter the password, as when you connect to the internet or access files on a partition that's not home, or install new software.

I have a Kerberos/LDAP/OpenAFS server running on Debian lenny, set up according to Davor Ocelic's excellent guide here (url). SSHd has ben configured to use GSSAPI auth and the clients have been configured to pass auth tokens through to the server.
My clients are all Ubuntu 9.10 x86 fully patched. On the clients, OpenAFS has been compiled and installed as a kernel module and git 1.6.6 has been compiled from source and installed. Otherwise, all software is stock Ubuntu repository-ware.
The setup is working fine as long as I connect to the primary server using its hostname:
peter@client01:~$ ssh nana
<connection goes through seamlessly without prompting>
peter@nana:~$
If I try to connect via a DNS alias (actually a second CNAME record), I get:
peter@client01:~$ ssh git1
peter@git1's password:
<connection completes>
peter@nana:~$
I need both passwordless auth and the DNS alias working, as it's internal policy that user connections are only ever made to service names, not real hostnames.
I have tried adding a second host principal to Kerberos for the alias (git1.darling.local) in addition to the host principal for the hostname (nana.darling.local).
If I turn off PasswordAuthentication in sshd_config, then "ssh git1" doesn't even fall through to passwords; it just denies logins. So it looks like it's not even using GSSAPI for the DNS alias.
So:
1) Is what I want even possible? I can't find anything that indicates that there's anything odd about DNS aliases such that this should happen.
2) Which config files should I post to help debug this? There's a lot and I didn't want to start blarfing them here if they aren't helpful.

I want to connect to the same machine that that I have OpenSSH server on which uses keys and I have disabled password-based logins (for ssh). Apparently, this also affects SFTP which makes sense. How do I setup SFTP to use key-based authentication?

I run some IT systems for my schools Engineering student organization.
We are upgrading our systems and I just purchased a new server system which I am configuring.
I am using Ubuntu 10.04 Lucid Lynx and the new likewise-open packages.
The points I bring up following this sentence are to fulfill this final goal : Get SFTP, SSH, and Network Share's over our private network all using the schools Active Directory for auth and it's groups to derive privs.
So... Here's what i've done and what i've tried to do.
1 ) I set up likewise-open and got it to join the domain. When I do this I can ssh to localhost as 'schoolnetworkADname'. So that part works (hurray). To get a network share to use these same auth methods I have tried installing likewise-open-server. Everything launches find and the daemons run, but when I go into computer management on a windows server to set up the actual shares, I get permission denied. The account it is giving permission denied to is the same AD account that join likewise-open to the network, so... what is going on.
2 ) Samba, fail. I can't seem to get samba to run on this machine at all, which is strange because even my Samba expert was puzzled. It just won't let Samba join the domain properly, and due to this, I want to keep on the newer likewise package... unless I have to switch to this.
How I can get the lame likewise-open-server to work?

I am attempting to set up an automatic transfer via sftp using public key authentication. I have created a public/private key pair to connect to the remote server without using a password. I have also been able to use this key pair to login from the command line: sftp -vvv -oPort=<server-side port> user@server.Debug info from interactive command:
Code:
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey

Can't seem to do it, wondering if anyone knows how? Normally there's something in sshd_config that can be switched to true or yes to allow root login but I can't see it in fedora 12.I can login via root at a terminal no problem, just not via ssh, I get access denied every time. Also, I need to login using password authentication.I've done: 227169 but that's just for GUI which I don't really need since I rarely ever log into the GUI.I have also searched through here and mostly only found info such as above, how to enable root login for GUI, or billions of posts about how logingin as root is bad but I cannotswer to my question.DISCLAIMER: Please do not reply to this thread if all you can contribute is the question of why I need root or to put some message telling me I can do everything using su, etc, etc. Please only contribute if you can answer my question. A: My machine and a valid quesiton. B: Spirit of Linux is open, not restrictive

I just installed Fedora 12 on HP Pavilion (dual boot with Windows vista). I made it all the way through the installation and created my user account. A few seconds later I got the login screen asking for my password. I enter the password and get "Authentication Failure."
The name that shows up on the login screen is my full name, not the user name that I created. Is that wrong?

I have a rather difficult problem. Every time I need root privileges and I am asked to authenticate (i.e. Update Manager, mounting a partition, etc), the password window comes up, shakes and immediately closes, leaving me with no chance to enter a password. What to do?edit: this is NOT the login window, just the little dialog that pops up when you need elevated privileges.

I wrote a script ages ago to automate an FTP transfer. This was easy as within the script you can specify the password with password <whatever>. Now I am wanting to do a similar thing with SFTP (SSH). I know that SFTP works differently and I cannot specify the password within the script - what do I need to do on the server I am connecting to to either "trust" the host I am connecting from or to somehow specify the password for "sftp user@some_host"? It's IP address will always be the same.

I am running a small ubuntu-server headless machine at home. It is configured with sshd so that I can connect from anywhere (if I have Internet access.)However, there is a thing: I'd like to have good security and disable password authentication, but I also want to be able to connect from a PC that I've never touched before. And no, I'm not prepared to type a 256 bytes password every time I type "sudo ..."
Here is what I thought: I could have a login (pieroxy) that has a moderately strong password and another user (pieroxy-ext) that has a very strong password (100+ chars.) I would use my regular account (pieroxy) whenever I have a key-based authentication and the other one (pieroxy-ext) whenever I have a password-based authentication to do. Then, I'll just su to "pieroxy" and I'm done typing the 100 chars pwd. In order to do that, I would need to be able to configure my machine so that password-based authentication is disabled for all accounts but enabled for my account that has a strong password (pieroxy-ext). Is it possible to disable password-based authentication on a user basis?

I am running Ubuntu 11.04 which I like very much (except for Unity - so I am using Ubuntu Classic).
Whenever I try to use "su - " I get Password Authentication Failure. I have checked Caps Lock (obviously) and have also tried resetting the password using "passwd" - but with no success.
If I use "sudo ...." with a command the password is accepted.
I have the same software installed on two computers but the problem only occurs on one - the other is OK!
