Disabling external network connection attempts


Disabling external network connection attempts
Prev	Obtaining installer patches	Next

When you execute the installer command, the installer attempts to make an outbound networking call to get information about release updates and installer patches. If you know your systems are behind a firewall, or do not want the installer to make outbound networking calls, you can disable external network connection attempts by the installer.

To disable external network connection attempts

Disable inter-process communication (IPC).
To disable IPC, run the installer with the -noipc option.

For example, to disable IPC for system1 (sys1) and system2 (sys2) enter the following:
```
# ./installer -noipc sys1 sys2
```
