Spacewalk installation problems

Spacewalk installation problems

Error:
Tomcat failed to start properly or the installer ran out of tries. Please check /var/log/tomcat*/catalina.out for errors.

Solution:

yum install geronimo-jta-1.1-api.noarch
/usr/sbin/spacewalk-service restart
 
Error:
** Verifying certificate locally.
There was a problem validating the satellite certificate: 1 
 

The most current Red Hat Proxy Server installation process against RHN hosted
requires the upload of an SSL tar archive that contains the CA SSL public
certificate and the web server's key set.

Generating the web server's SSL key set and CA SSL public certificate archive:
    /root/ssl-build/test1.localdomain/rhn-org-httpd-ssl-archive-test1.localdomain-1.0-1.tar

Deploy the server's SSL key pair/set RPM:
    (NOTE: the Red Hat Satellite or Proxy installers may do this step for you.)
    The "noarch" RPM needs to be deployed to the machine working as a
    web server, or Red Hat Satellite, or Red Hat Proxy.
    Presumably 'test1.localdomain'.
Preparing packages for installation...

Solution:
yum install  spacewalk-utils
*add HOSTNAME to /etc/sysconfig/networkspacewalk-hostname-rename [IP ADDRESS]
it will regenerate new SSL certificates. 
 
*recreate CA certificate on Spacewalk server 
 
 /usr/bin/rhn-ssl-tool --gen-ca --set-country="US" --set-state="NY" --set-city="Golden" --set-org="mypublisher" --set-org-unit="spacewalk.server.com" --set-common-name="spacewalk.server.com" --set-email="webmaster@server.com" --force

How to check cisco interface index number

How to check cisco interface index number

 Remotely via SNMP:

 snmpwalk -c {community-name} -v 2c {IP} ifName

for example:
snmpwalk -c public -v 2c 192.168.0.1 ifName 


Locally on Cisco device:

> enable
#show snmp mib ifmib ifindex

[Solved] Nagvis weather map (traffic map) and Centreon & Nagios

To fix weather maps (traffic maps) with Nagvis and Nagios & Centreon you have to fix 3 things:

1. You have to modify the code of the check script (check_centreon_snmp_traffic).
In this script you have to modify the following line :

printf("|traffic_in=".$in_perfparse_traffic_str."Bits/s;$warningBit;$criticalBit;0;$speed_card                  traffic_out=".$out_perfparse_traffic_str."Bits/s;$warningBit;$criticalBit;0;$speed_card\n");

and replace with:

printf("|traffic_in=".$in_perfparse_traffic_str."Bits/s;$warningBit;$criticalBit;0;$speed_card traffic_out=".$out_perfparse_traffic_str."Bits/s;$warningBit;$criticalBit;0;$speed_card load_In=".$in_usage."%%;$warningBit;$criticalBit;0;0 load_Out=".$out_usage."%%;$warningBit;$criticalBit;0;0 traffic_In=%.2f".$in_prefix."b;".$warningBit.";".$criticalBit.";0;0 traffic_Out=%.2f".$out_prefix."b;".$warningBit.";".$criticalBit.";0;0 \n",$in_traffic,$out_traffic);

2. The file you have to modify  next is : /usr/share/nagvis/share/frontend/nagvis-js/js/NagVisCompressed.js
 
You have to find the function "drawNagVisLine"  and replace it with:

function drawNagVisLine(objectId, lineType, cuts, x, y, z, width, colorFill, colorFill2, perfdata, colorBorder, bLinkArea, bLabelShow, yOffset) {

y[i] = parseInt(y[i], 10);
