I start/stop lots of new instances as I'm learning to use Amazon EC2. Every temporary instance is added to the known_hosts file. Is this ever a problem for others who use EC2 a lot?
I'd like to tell ssh to skip this step anytime I connect to amazonaws.com. Is there a way to do that in the config? I'm using Linux & openssh.
I have an automated setup (debian) which includes a startup script that rsyncs to a server (always the same server). Everything works well - just that I have to manually confirm that the host is supposed to be added to the known_hosts
Code:
The authenticity of host 'myserver.com (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 9b:ee:a6:47:hb:92:ac:76:81:94:18:7d:ad:8c:3e:25.

I was wondering if it's possible to move the known_hosts file from ~/.ssh/known_hosts to ~/somewhere/.ssh/known_hosts . I have a server running Plesk and the user home directories do not have write permissions (they do have write permissions within the subfolders, however).
I was able to move the authorized_keys file by editing sshd_config AuthorizedKeysFile , but when I try to log in without password, I'm still prompted every time if I want to add the host to list of known hosts, and it fails to save every time since it cannot write to known_hosts. Thus I am still unable to automate some processes. I'd like known_hosts to be located in the same location as my authorized_keys, which does have correct permissions for users.
I had a populated known_hosts file. I was editing it and for a split second I saw a permission error when I saved it. I went to check what the error was and the known_hosts file was blank.
Now if I ssh to a host I get something like the following:
bash-3.2$ ssh root@
The authenticity of host '' can't be established. RSA key fingerprint is b3:c3:e3:83:23:83:93:63:13:23:63:63:d3:c3:33:a3. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ' (RSA) to the list of known hosts.
Sounds good... but when I look at my known_hosts file, it is blank. I check the permissions and it is owned by my account. .ssh/ permissions are correct too.
I deleted known_hosts and then tried connecting again, and it creates a file but it stays blank. No host keys get added.
It just started happening after I saw that permission error.
root user's known_hosts file updates fine though.

I just installed nagios to a Cent 5.4 box. Everything is working so far except I want to add a plugin I found on nagios exchange. The file has a .pl extension. I am unsure how to add the plugin to the rest of nagios. Do I need to add it to a nagios folder and then define it. If I just try to run the pl file I get a error mesg. I am unsure if the error is caused by system misconfig or because the plugin is not installed. The plugin is check_dayime.pl and the error I get is Can't locate Date/Parse.pm Perl seems to be working as I can run simple perl scripts and perl -v spits out v 5.8.8

I'm trying to output two certain fields of a very large text file to 2 very small text files. Then take those files and add all the lines together to come up with a total from each file (two totals).
Here's what I've got:
Code:
#!/bin/bash
echo "0" > /media/in.txt
echo "0" > /media/out.txt
[code]....
Breakdown: Put 0 in a text file to be drawn by respective while loops for math later
Output last 60 integers to a file for total A (new integer every minute)
Output last 60 integers to a file for total B (new integer every minute)
The two while loops are supposed to be adding the lines together. The echo commands at the end are for testing purposes, just to see the output. However, when I run this, I get the output of
Code:
0 0
Which is obviously not what it's supposed to be. Is there a more efficient way to do this or am I missing something in the script that would reset the values to "0"?

Once I have found appropriate software which I would like to add to my computer, (which is Linux Compatible)... what are the steps, in the simplest terms to start using it?
To confirm, I have got to the stage where the program is on the computer but as no "window" pops up... I am fairly lost to get it from the completed downloads to actually start using it... is it an option like extract? Could you give me the basic steps.

View 4 Replies View RelatedMy Linux OS is mounted on a LVM spread across an 8GB SD Card and a 4GB Flash Drive. I've used about 6GB and have about 2.xGB left. I'm trying to download Sabayon and I don't quite have enough space to store DVD size ISO. I have extra 2GB Flash Drive that I am not using and can converted to a PV and that would give me the necessary space I need to store the ISO. Now the ISO would spread from 4GB Flash to my 2GB Flash. My question is complicated, so bare with me. I want to know by adding 2GB PV into LogGroup and then remove it from the same LogGroup and then added back later. Would the data still exists and accessible? What happens to the data when I remove it the first time, would be automatically deleted, or stay hidden to plug back in?
