We've confirmed this behavior, and added this to our TODO list. We will let you know as soon as this is fixed.

Meanwhile, you can try accessing it not by IP, but by hostname, and map the hostname to localhost in the /etc/hosts file.

Hope this helps.

Actually looking at this we believe it may be cause by allow_fopen_url being turned off in the php.ini. You can check the value by running in terminal:

Code: Select all

cat /etc/php.ini | grep allow_url_fopen

Can you confirm that 172.29.70.37 is the IP of your XI server?

[wiproltdwiv]

[root@EMSNagios1 ~]# cat /etc/php.ini | grep allow_url_fopen
allow_url_fopen = On

[root@EMSNagios1 ~]# tail /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.29.70.37 EMSNagios1.co-opbank.co.in
10.128.17.12 EMSNagios1.co-opbank.co.in EMSNagios1


Our Nagios server physical ip is 10.128.17.12 and we access with, also we have mention http://172.29.70.37/nagiosxi/ this url in system setting so we can access nagios from remote location and it is NAT IP.

Have you tried adding localhost to the 2 addresses of the localhost in /etc/hosts?

Code: Select all

172.29.70.37    EMSNagios1.co-opbank.co.in localhost
10.128.17.12    EMSNagios1.co-opbank.co.in localhost     EMSNagios1

[wiproltdwiv]

yes we tried the same. but still we struck with same issue

[scottwilkerson]

In my opinion, the /etc/hosts should contain just

Code: Select all

10.128.17.12    EMSNagios1.co-opbank.co.in localhost     EMSNagios1

Then if you access the page by name (EMSNagios1.co-opbank.co.in) and not IP address it will do the lookup based on that, which the XI server should see it as 10.128.17.12
