Hi,
I am trying to build a mail server starting from the base GSC from the catalog.
Currently the /etc/hosts file looks like this

127.0.0.1 GSC.main localhost.localdomain localhost mail.mydomain.com mail GSC

and i need it to look like this

127.0.0.1 mail.mydomain.com GSC.main localhost.localdomain localhost mail GSC

because the email sending program(sendmail) puts the hostname as beeing the first after 127.0.0.1.
I have edited manually the hosts file but it is rewritten on app restart. Can you please tell me what script does that and how can i modify the script to work the way i wanted?
Thank you ,
Daniel

Hello,
i am trying to use this appliance and can not get it to resolve any network addresses. I am not sure what is wrong. Here is my output from ifconfig on the appliance.

Any help would really be appreciated!!

sdamron,

1. What is the appliance? I assume it is an instance of a GSC template.

2. What are the nameservers configured as properties -- e.g., the dns1 property; make sure it is correct. You can see what is configured in /etc/resolv.conf

3. Try pinging a known IP address first: e.g.,
ping 209.128.123.196
If this works, then you have access to the 'net but no DNS.

4. If you don't know what DNS servers to provide, consider using OpenDNS: dns1=208.67.222.222 and dns2=208.67.220.220

Let me know if this helped.

Regards,

How can we add a mon appliance to the GSC template, so that we can monitor the resources for any applications created using the GSC template on the dashboard?

[JeremyN]

You would just need to edit the GSC class and add a mon terminal to the appliance under 'Interfaces' then set the protocol type to 'cce' and connect it to a mon appliance.
