May 5, 2010
When I do 'sudo apt-get update' I get this error now:

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

My software sources some how got screwed up. Now when I try to install from software manager or Synaptic, I get error messages. Here is the error messages at the bottom of "sudo apt-get update" :

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?
I have added the following line in sources.list, deb [URL] squeeze main non-free
Running apt-get update i get this error message, Reading package lists... Done W: GPG error: http://www.debian-multimedia.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 123456789
Do i need to generate this public key 123456789 ? If so, how?
Running apt-key update has not solved the problem.
apt-get install debian-archive-keyring was a recommended solution from some googling.
I have also read this page, [URL] , but how to add a key is under construction.
How can I forward all traffic from a public IP to another public IP. Let's say I have a first debian box named box1 with eth0 = 1.1.1.1 and eth0:1 = 1.1.1.2 and I want to forward all traffic from 1.1.1.2 to "box2" located somewhere else over the internet and having for eth0 2.2.2.2 Both 1.1.1.0/24 and 3.3.3.0/24 are public IP ranges.
Just added Squeeze multimedia repositories in source list,but get this after reload :

However,update for Audacity & Mplayer showed in Update Manager,and I successfully updated.
I did create an rsa certificate with ssh-keygen using my root account on a client: ssh-keygen -t rsa -b 2048 no passphrase I did copy the rsa pub_key from my client to the server scp id_rsa sampleuser@sampleserver:/home/sampleuser/.ssh/authorized_keys
I did change the ownership to the "sampleuser" of the pub key file on the server: I trayd to connect: ssh sampleuser@sapleserver
I get that: permission denied (public key)... I know I do smth wrong but I don't know what.
When I go to the Update Manager to update my system I get the following error message: W: GPG error: http://packages.medibuntu.org lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2EBC26B60C5A2783
I am not sure what this exactly means and what I need to do to fix this.

Setup:Two Fedora machines in a large network, with a Win2003 server in the epicentre.Goal:To share files through the Public folder.Results so far:I put files in the public folder, I enable anything I can find related to networks in the Firewall (samba, nfs, and even www (http). In the public folder preferences, I set 'Share over a network' and never to ask a password. I do all this on both machines.Then I open Nautilus, and click on the network link. After a little while I get three links:Windoze network, public files on computer 1, public files on computer 2. Let's say I'm on computer 1, if I click on the public files on computer 2, I get the following error:

I'm trying to add the PGP public key for the new repository. Here are the two lines I want to add for my e-mail but don't know where to add on the new repository.[URL]... I went to to the Synaptic Manager but could not find or where to place it. Would I create a new repository?

I'm completely new to Ubuntu, I've just installed 10.04 and this is only the second week I've had it, and I'm not sure what is going on with this. Whenever I try to check for updates I get this message: The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

I am trying to figure out the best way to set up 1-1 NAT for three public ips to three private ips through a ubuntu gateway machine.
I am running ubuntu server 9.10 and the set up is:
Internet/ISP modem -> NIC 1 Ubuntu Gateway Machine NIC 2 -> Three PCs with Private IPs
I had a few questions on how to do this correctly and securely.
1) What packages do I need to install (aside from the basic ubuntu server installation and possibly DHCP3-Server)
2) How do I assign all three public IPs to the NIC connected to the ISP modem? All addresses will be static, will I need the DHCP3-Server package?
3) Once I have the three public IPs assigned how do I map each specific public IP to the private IP address associated with it and provide the correct loopback? I want to make sure each response from the internal machines are sent out as their specific public IP.
4) Aside from allowing all connections, how should IP tables be configured to allow web services to one internal machine, mail to another internal machine and DNS to the other internal machine?
Currently I am having troubles getting my ssh key to work correctly. I have had a desktop crash which has been reformatted to use ubuntu. The key residing in id_rsa.pub has been copied over to the ssh server into the authorized keys of the given user. however When we try to login we get a "permission denied (public key, keyboard-interactive)" error. below is the debug option:
jv@ops-desktop:~/.ssh$ ssh -v jv@x.x.x.x OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for *
I am trying to debug a problem where I can't connect to a remote SSH server. I do not have admin rights on the box, however I have a valid account and can login fine with a password, I just wanted to use my public key instead.
I copied over my ~/.ssh/id_rsa.pub to the remote server to ~/.ssh/authorized_keys. I tried to connect to the server but it is not allowing me to authenticate when I ask it to use public keys instead of passwords.

I set up an SSH server on my home machine and finally figured out that I needed to disable password authentication to get RSA authentication enabled. Now I'm having problems with that too.ssh -v -i id_rsa ashtray@x.x.x.83

I've got a p12 certificate (I own the secret key), and I would like to export the public key to gpg keyservers. How to achieve this?It works flawlessly inside gpgsm and kleopatra, but I cannot send keys:
Code: $ gpgsm --send-keys 0xDA4E5DD0 gpgsm: this command has not yet been implemented
I'm on Natty Narwhal and wanted to play with ssh but I can't seem to get ssh to work without having to specify a password. I've installed openssh-server. I've generated a public/private key pair:
ssh-keygen
I can see my id_rsa and id_rsa.pub and known_hosts.
am logged in as user pgroarke and simply trying to run ssh on the same box. Regardless of whether I specify either localhost or hostname I still get asked for a password:
ssh -i ~/.ssh/id_rsa.pub pgroarke@spock date pgroarke@spock's password: Here is the relevant contents of my /var/log/auth: Jun 18 16:21:37 spock sshd[30357]: last message repeated 2 times
