skipif: Managing Network Interfaces

skipif is used to add SKIP to or delete SKIP from network interfaces. skipif is also used to save SKIP's ACL for a given network interface so that it is permanent across system reboots. In addition, skipif is used to list the network interfaces present in the system and optionally to print the current access control configuration for each network interface.

SKIP's ACL for each network interface is stored as a text file (as a series of skiphost commands to be executed during SKIP start-up). SKIP's ACL files are under the /etc/opt/SUNWicg/skip directory and the ACL file name for a given interface is acl.<interface name> (for example, acl.le0, acl.hme0, and acl.qe1). If an incorrect or incomplete ACL prevents the system from operating, it may be necessary to modify the file manually or remove the appropriate file. Some non-LAN interfaces (PPP, for example) will not be configured at boot time even if an ACL exists for these interfaces. It is the responsibility of the user in the interface configuration procedure to use the SKIP configuration file for this interface.

skipif notifies the user if it is necessary to reboot the system so that any changes will take effect.
