Unable to login using the nagiosadmin credentials

[sgiworks]

Hello Team,

Unable to login to Nagios Log Server using the default 'nagiosadmin' credentials, could you please help in troubleshooting this problem as I need to get in.

I am able to connect the page but it keep on giving wrong credentials, also when I try to reset password using forgot your password link. It says 'The username does not exist.'

Version: 2015R1.0

Note: I can connect through SSH session using ec2-user

Regards,
Swapnil

If you can login via SSH, you should be able to use the following script:

Code: Select all

/usr/local/nagioslogserver/scripts/reset_nagiosadmin_password.sh

Do I need to restart the server after resetting the password?

[mcapra]

You shouldn't need to restart anything. Much of the Nagios Log Server configuration exists in a special elasticsearch index, so if the elasticsearch service is crashed this script may fail. You could try service elasticsearch restart followed by the script if this doesn't seem to be working.

I have another server where I cannot get through the portal, after connecting SSH I tried 'service elasticsearch restart' but that failed with error 'elasticsearch: unrecognized service'.
So we tried to upgrade the install, however even the upgrade failed with following error:

Installed:
php-ldap.x86_64 0:5.3.3-48.el6_8 pyOpenSSL.x86_64 0:0.13.1-2.el6

Dependency Updated:
net-snmp-libs.x86_64 1:5.5-57.el6_8.1

Complete!

Was this server in production? Very strange for an NLS setup to suddenly lose elasticsearch.

• Can you share the install.log?
• Can you share the output of:

  Code: Select all

  ls -al /usr/local/nagioslogserver/elasticsearch/

[sgiworks]

This is not a production server yet, but will need to setup one.

[ec2-user@ip-10-1-252-201 ~]$ ls -al /usr/local/nagioslogserver/elasticsearch/
ls: cannot access /usr/local/nagioslogserver/elasticsearch/: No such file or directory

• Can you share the contents of your /etc/ntp.conf file? If it doesn't exist, try yum install ntp.
• Do you know if the network this server is being deployed on is blocking NTP packets? This is done to mitigate/prevent DDOS attacks on some networks.

[sgiworks]

Attached ntp.config

Do you know if the network this server is being deployed on is blocking NTP packets? This is done to mitigate/prevent DDOS attacks on some networks.

Please answer this.

What is the output of the following?

Code: Select all

ntpdate -u 0.centos.pool.ntp.org
