myusuf3's questions

I have come across this problem a couple of times when creating build servers with keyed authentication.

I was wondering if anyone else has experience this. I have a couple of keys for my current user that may connect to different machines. Let say machine1 and machine2. I have pasted my public key into their respective authorized_keys file. The first one I have named the first key id_rsa and the second key bender.

When I try to connect to bender I get the following output with my verbose ssh connection

debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug1: SSH2_MSG_NEWKEYS received
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Trying private key: /home/bozo/.ssh/.ssh/identity
debug1: Trying private key: /home/bozo/.ssh/.ssh/id_rsa
debug1: Trying private key: /home/bozo/.ssh/id_dsa
debug1: No more authentication methods to try.
Permission denied (publickey).

It only offers the id_rsa key, as you can see above. Is this correct? If so why? How do I get it to offer more keys? I know it is a problem I see intermittently, because I at home I have multiple keys without much trouble.

I would also appreciate a overview on how the pub and private keys interact with the client and server. I thought I had a pretty decent idea, but apparently I am missing something.

Please and thank you.

I am assuming that all application installed through apt-get are open source; but for those that are available in that manner, where can I get the source code for these applications as well as update them?

I have a couple applications I use regularly that aren't being actively developed any longer and I would like to add features. Where would I go to get the rights to update these applications?

In this case specifically, I am referring to the hellanzb package

How do you mute the sound system from the command line?

I ran the following commands

sudo apt-get install libapache2-mod-wsgi
sudo a2enmod mod-wsgi

I keep getting this extremely frustrating message

ERROR: Module mod-wsgi does not exist!

Please help.

I recently ran chkrootkit and got the following line:

Searching for Suckit rootkit...                   Warning: /sbin/init INFECTED

What does this mean exactly? I heard this was a false positive, what is exactly happening.

Please and thank you.

I was hoping someone could recommend a good password generator.

Extra props to the person who can name one that gives you a mnemonic to remember it as well.

What does this mean?

sudo add-apt-repository ppa:maco.m/ruby
sudo apt-get update
sudo apt-get install rubygems

Hows does it differ from running

sudo apt-get install rubygems

?

I ran the following code and got this package needs these packages, now it also says these packages are suggested, and theses are recommended. How do I get those up to install as well.

I would like to know how to upgrade from my current version of Ubuntu to the next stable from the Command line interface?

How do I install fonts on Ubuntu Linux? I need them to be available in gimp.

I write code. I use terminal a lot. I ofter use many terminal windows. I hate how tabs look.

Are there any applications that allow me to keep multiple terminal windows in focus to streamline my development?

What's the point of the examples.desktop file?

I was wondering how do you know where the largest files in my system are stored.

For example---

Disk Space Used: 1GB Java: 500MB Java Percentage: 50% maybe represented in a pie chart. Maybe?

I know this maybe a feature overkill. I sometimes forget having stored things and wonder why my disk is so full.

So basically a command that will allow me to run on the file system and provide me with information on disk space used.

Please and thank you.

The OCD in me wants directories I do not like the name of to be hidden since I do not interact with them directly.

How can I hide directories without using the dot notation?

I was hoping to know if Ubuntu comes with a standard way of mounting ISOs. I looked around online and found a bunch of scripts that can do it.

This to me seems like core functionality, is it offered by default in Ubuntu. If not where is the best and simplest mounter for ISOs.

I would like to know how to resize images in Ubuntu. What is the easiest tool to do so?

Seeing there are various ways to install on Ubuntu. What are the various ways to uninstall items?

Which ways always work? How can I be sure something was uninstalled?

How can I run scripts automatically when Ubuntu starts up so I don't have to run them manually after startup?

I have a script that needs to be run every five seconds. I know that cron can do tasks by the minute, but is there a way to run something every second?
