Applications :: Openssh, Create A Public Key Authentication From Cli Only?

Jul 4, 2010

Im trying to create a public/private key for open ssh, I don't really know what difference between the two. I want it to all be one command and not have to hit enter after each command. Here is what I mean:i type "ssh-keygen"and it asks me were to save, then my paraphrase, then reenter the paraphrase.I just want to be I guess you could say unattended if that makes any sense.

Ubuntu Networking :: OpenSSH Public Key Authentication Not Working?

May 22, 2010

I'm trying to get OpenSSH public key authentication to work. My server runs ubuntu. My client is a windows machine, and I'm using cygwin. I tried using the instructions here: [URL]... If I test it out using this line: ssh -v -v -v -o PreferredAuthentications=publickey server.example.org

I get this:
debug3: no such identity: /home/Julie/.ssh/identity
debug1: Offering public key: /home/Julie/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug3: Wrote 368 bytes for a total of 1477

I'd like to ask one simple question I can't figure out how to solve.I've set up my public key authentication by generating the public key on my Windows box. Copied that into /root/.ssh/authorized_keysDisabled password authentication in /etc/ssh/sshd_config:

#Port 22

Debian :: Public Keyrings And Authentication?

Jan 3, 2011

I often run into this and it's such a hassle that I have had no choice but to ignore it. But, I would like to run it properly but I don't understand why my sources list is 'wrong' or has incorrect info so that it's often not verified or authenticated. The public keyring is wrong or the source or both? I get these messages, for e.g.:

# apt-get update && apt-get install dmo-archive-keyring && apt-get update exit with result:
W: GPG error: http://unofficial.debian-maintainers.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9EEBC8DB9B9C3CB6

I probably don't need that but I ran into a similar error trying to authenticate the multimedia keyring. Not sure it worked but I am guessing the system works the same with all the authentications? I hope to understand what I'm doing wrong and what the process is.

General :: Github Private/public SSH Key Authentication?

Jan 28, 2011

I created a private/public pair. I put the public on github.But I can never push to github.Every time, it says public denied. In order to push, I need to do this:eval ssh-agentssh-add ~/.ssh/github_dsaThis is driving me nuts that I have to do this every time. So, I just put it in my ~/.bashrc file. I feel like that's a hack. Is this normal?

Ubuntu Networking :: Public Key Authentication Fails?

Feb 6, 2010

I'm trying to connect to my Xubuntu box (zelda) remotely using my RSA key. I'm using Cygwin on my Windows box (link) to SSH in to the Xubuntu box. I've created the key and placed it in the authorized_keys file on my remote box. Here's where it gets weird. When I ssh into zelda the first time, it prompts me for my password. However, if I'm already connected to zelda and try to open another connection, it prompts me for my RSA passphrase. This is very confusing, and I have no idea what's going on.Here's my sshd_config file on zelda.

Code:
# Package generated configuration file
# See the sshd(8) manpage for details

Networking :: SSH Setup - Public / Private Key Authentication?

May 7, 2010

After years with Linux and using ssh on a daily basis I have to admit I've never setup public/private key authentication and I've never run passwordless logon to ssh. It's not that I've never tried, I have - I've just never got it working. That to me is an almost alien concept as I am a tinkerer at heart and rarely stop until something is working the way I'd like it to. I get the principle of what's going on but I've always had a mental block about it.

Debian Configuration :: Exim4 Public Not Requiring Any Authentication

Jul 9, 2015

I've installed it properly until it works now, it does send emails and receive them, but heres the problem.

1) it does not send emails to a certain domain, unless i do dpkg-reconfigure on exim4 and put the domain on allowed relay... can't i just put something on settings which allow to send emails to ALL domains?

2) EVERYONE can connect to the server by telnet from any position, terminal or pc, and just use an existing user to send emails to anyone.... example, i have testuser123 setted up in debian/exim4 .. then they simply write "mail from:testuser123@host.dot" and the server accepts it.. without even request an authentication for that. And this is a problem, because everyone can use my email addresses to send emails to whoever.. heaven for spammers/hackers..

Ubuntu Networking :: Ssh Public Key Authentication Only Works When Already Logged In?

Jan 6, 2010

I have an ssh (OpenSSH_5.1p1 Debian-6ubuntu2) client A and a server B set up for public key authentication as described in [URL]

The problem is the following: ssh asks for a password when connecting from A to B without any other ssh session going on between A and B; but if I connect from A to B whenever there is another ssh session between A and B, either I get prompted for the passphrase I used to encrypt the private key or I get logged automatically.

I already checked permissions on B: .ssh is 700 and authorized_keys is 600. I already tried "StrictModes no" in sshd_config. Printing debug information using DEBUG3 does not any useful insight. Moreover, there is no /var/log/secure (is it supposed to be there?)

Right now the computer is far far away from my reach, but when I configured the system I noted that whenever I was locally logged to B and then ssh'ed from A to B, I was logged in without any problem; whenever I was not logged in locally I was asked for a password. Note that at that time I was using a different public/private key pair whose private part had no passphrase.

how to know exactly what cipher is ssh/sshd using for a particular session? Is there a way to know any statistics for a given session (something like the ~s option in section 5 of [URL]

P.S. 2: does the following mean that ssh is using protocol 2.0 or something different than protocol 2.0?

(..........) sshd[2606]: debug1: Enabling compatibility mode for protocol 2.0

Ubuntu :: Disable Password-Authentication Using Public / Private Key With Ssh

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.

Ubuntu Networking :: Create A New Virtual Network Using A Subnet Of Public Range

Jan 27, 2010

There seems to be a lot written about virtual networking but I am not sure what approach to take in my situation. My local subnet has a public block of 128 addresses. I have a virtual host running on my machine. My machine has a static address and I'd need to assign one to the guest. I have edited the guest's interface file and assigned a public address to it's eth0. However the guest cannot ping out and I can't ping in.

By default the virtual machine manager creates a virtual network (virbr0) and assigned a private address range to it. I have tried to create a new virtual network using a subnet of my public range (/31) but the manager says the range must to a minimum of 16 addresses (/4). It doesn't look possible to achieve my aims using the virtual machine manager.

In the past I have used the procedure laid out here:[URL].. which is to manually create a bridge. I am not sure that is relevant for my 9.10. I think I would have to disable the network manager if I were to do that and I am not sure how to do that.

Ubuntu :: Use Openssl Public And Private Keys So Only A Host With The Public Key Could Access / Decrypt The Filesharing

Aug 2, 2011

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

General :: Mv: Cannot Stat `/public/public/clamscans/*.txt': No Such File Or Directory

I run the following file with the >log.log redirector and it does not capture errors.

#!/bin/bash
echo ************************BEGIN LOG******************************
date +"%m/%d/%Y %H:%M:%S $HOSTNAME"
cp -f /scripts/original/clamscans.log /scripts

[code]....

The following errors show up when I run from the file from the term window, but are not written to log.log:

tar: /public/public/clamscans/*.txt: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors
mv: cannot stat `/public/public/clamscans/*.txt': No such file or directory

I know with windows you can add the 2>&1 to capture error data. Is there such a thing for Linux?
