Hi Andrew,

The problem was solved, thanks. But the message with the etc/hosts is still there, but now, when I click to repair, it really “fix” the /etc/hosts:

[root@perfsonar ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

The curious is that, even after “fixing” it, the message remains asking to fix again.

Thank you very much,

Jeronimo

Hi,

Not sure how it happened, but in your owmesh.conf file the BWWindowSize is set to '16Mm' in two places. It should just be '16m'. Do a search and replace and the problem should go away. I was able to load the owmesh in a local instance and get the error, and when I replaced those two lines thing started working normally.

Thanks,
Andy

Hi,

the statement about /etc/hosts has gone. My /etc/hosts:

Hi,

Does the message about /etc/hosts persist or is it now just the "Problem reading testing configuration: Problem reading perfSONAR-BUOY Configuration" message? Could you send me the contents of /etc/hosts and /opt/perfsonar_ps/perfsonarbuoy_ma/etc/owmesh.conf?

Thanks,

Hi Andy,

I’ve changed the /etc/hosts a couple of times, no results:

this way:

this way:

The name perfsonar.ampath.net points to 190.103.184.153 and the reverse DNS is also working fine.

I even reloaded all process. Anything else?

Hi,

Likely the new /etc/hosts entry caused the issue. If I recall correctly, the message gets displayed if the address it finds for the host (in this case perfsonar.ampath.net) yields a different result in DNS versus a call to getaddrinfo() which may also hit /etc/hosts. I am not sure if the /etc/hosts entry you added will affect this, but it looks like the script thinks it does. You could back up the /etc/hosts file and try clicking the link in the error message to repair it. If the error goes away you at least know the cause and we can try to figure out what it doesn't like about the new entry.

Thanks,
Andy

Hello all,

we are facing this problem in our perfsonar installation, since last week, and I need your help to fix it. I recreated the /etc/hosts, rebooted the server, nothing has changed. I don’t know what caused the problem since we don’t keep changing the configuration in our server. I don’t know if that happened after we fix the SSL problem, or it was caused because we created an entry in the /etc/hosts.

What kind of information could I provide to help you guys to help me?

Thanks

The on-disk configuration has changed. Any changes you made have been lost.

The /etc/hosts file appears to have been modified. This may cause unexpected behavior by tools. Click here to correct the file.
