a quick howto on ssh exchange key

How to do it

First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:
a@A:~> ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa): 
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A
Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):
a@A:~> ssh b@B mkdir -p .ssh
b@B's password: 
Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time:
a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
b@B's password: 
From now on you can log into B as b from A as a without password:
a@A:~> ssh b@B hostname
B

Hi Andrea,

Do you recommend to modify zCommandCycleTime to cath sub-minute calls?

Something like 20 seconds cycles?

it depends on your installation, and about how many server you've to monitor.

you can try and monitor how it works (see collector perfromance)

Hello Andrea,

Sorry the question out of context, but how can I monitor my zap channels?
For example, by running pri show spans have the status of all my links E1 active and functional, and if any of these channels fail, I received an email notification.

With zenoss is possible to perform this task?

I'm sorry for posting this here ,

i'm new to zenoss , and i'm trying to make this Zenpack to work ,

I've followed the instruction like this:

sudo su - zenoss

zenpack --install Zenpack.....egg

zenoss restart

ssh-keygen -t rsa

ssh-copy-id -i ~/.ssh/id_rsa.pub root@bla

ssh root@bla mkdir /zenoss

scp $ZENHOME/ZenPacks/ZenPacks.Lais.Asterisk/ZenPacks/Lais/Asterisk/libexec/* root@bla:/zenoss/

now i don't know what to do next

any help would be appreciated , thank you.

Update : i've made it work , so if there was a delete button i would have deleted my comment , thank you anyway.

I have gotten this to work without any check_by_ssh. Instead, I just use the default zProperties of the device. I set the username, password, and ssh port (if it has changed). Then, do the following for each of the command:

Set the "Use SSH" to "True"
Don't bother copying the scripts over to your device. Instead, just take the contents from each of them, and use that in the "Command Template" section.
Adjust the new "Command Template" to NOT use "/usr/bin/ssh" in it. And modify any variables such that there are two $'s instead of just one. So for example, the "show_core_channels" should be changed to this:

/usr/sbin/asterisk -rx "core show channels" | grep active | awk '{ print $$1 }' | tr '\n' ' ' |awk '{ print var1 $$1 var2 $$2}' var1="active_channel:" var2=" active_calls:"

instead of this:

/usr/bin/ssh root@${dev/manageIp} /zenoss/show_core_channels.sh

The "show_registered_trunk" should be this:

/usr/sbin/asterisk -rx "sip show registry" | sed -e '1d' | wc -l | awk '{print var1 $$1}' var1="registered_trunk:"

and the "sip_show_peers" should look like this:

/usr/sbin/asterisk -rx "sip show peers" | tail -1 | awk '{print status var1 $$1 var2 $$5 var3 $$7 var4 $$10 var5 $$12}' status="OK | " var1="tot_sip_peers=" var2=" Mon_online=" var3=" Mon_offline=" var4=" Unmon_online=" var5=" Unmon_offline="

I had this working with the instructions provided by hootjr29 and it was perfect for a day and then the graphs stopped and I can't get them to start again. The correct information on channels and such is being collected, but the RRD is not displaying anything. Seems to lose it the next model of the sever. Not sure what I am doing wrong that would cause this.

I'm using the 4.2py version and it's functioning wonderfully.

I added a new data point and graph to watch the number of ZAP channels since we were concerned about running out, here's the command I used:

/usr/sbin/asterisk -rx "zap show channels" | grep [0-9] | grep -v "[0-9] \{12\}from" | wc -l | awk '{print var1 $1}' var1="current_inbound_calls:"

Thanks!

Andrea, any update to this ZenPack? It looks great and would LOVE to help you test this. I have 3 Asterisk servers that are HIGHLY used that I could test this on. I would like to do it with the changes hotjr29 and riodutchie have made. We use inbound and outbound calls, and only T1's.

Hi,

what asterisk version you have?

1.6 or 1.8?

1.4 actually. Will this work with it?

community@zenoss.org — Fri, 09 Dec 2011 16:27:33 GMT

Hello,

I cant fix this problem when template is executing:

/usr/bin/ssh root@${dev/manageIp} /zenoss/show_core_channels.sh

i got this:

/usr/bin/ssh: /usr/local/zenoss/common/lib/libcrypto.so.0.9.8: no version information available (required by /usr/bin/ssh)

LD_LIBRARY_PATH is the problem?

Thanks,

DIego Perez

i solved my problem,

/usr/bin/ssh: /usr/local/zenoss/common/lib/libcrypto.so.0.9.8: no version information available (required by /usr/bin/ssh)

the library libcrypto.so.0.9.8 is linked by LD_LIBRARY_PATH (env variable)...

you can follow the next instructions:

Create a script for chanels, peers and trunks, and modify the command template to..

/<script_directory>/script.sh

Code example:

#!/bin/bash

unset LD_LIBRARY_PATH

/usr/bin/ssh root@xxx.xxx.xxx.xxx zenoss/show_core_channels.sh

In my case i had to modify all the scripts at asterisk server:

/usr/sbin/asterisk -rx "core show channels" | grep active | awk '{ print $$1 }' | tr '\n' ' ' |awk '{ print var1 $$1 var2 $$2}' var1="active_channel:" var2=" active_calls:"

Just delete one $ in all...

And i found an error in asterisk template, the trunk data_point is bad.. change it to the correct..

I hope this help ,

Hopefully someone can give me some type of insight as to what I'm doing wrong, but I have all the scripts monitoring and graphing correctly except for the show_core_channels.sh script, this happens to be the one that I actually need.

Can you anyone give in suggestions or tricks that they used to get this one to work? Did anyone else run into problems getting the core_channels script to function?

FYI, I'm have the scripts setup in the way that hootjr29 suggested.

Thanks in advance, any help or response will be greatly appreciated.
