Akeni LAN Messenger 1.2.104 (Default branch)
05-29-2008
Akeni LAN messenger is a cross-platform instant messenger client. It is a P2P program that works on your LAN without the need of an Internet connection or a dedicated server. The client has an user interface similar to AIM, ICQ, or MSN Messenger. It supports all the standard IM features such as chat, group conference, presence management, file transfer, and emergency alert/notification. Extra features include contact management and optional tabbed chat sessions.License: Other/Proprietary LicenseChanges:|

cmmodnet(1m) cmmodnet(1m) NAME
cmmodnet - add or remove an address or check whether an address can be added to a subnet or enable or disable a LAN interface in a high availability cluster SYNOPSIS
cmmodnet [-v] {-a|-r|-t} -i { IPv4_address IPv4_subnet | IPv6_address IPv6_subnet} cmmodnet [-v] {-d|-e} LAN_name DESCRIPTION
cmmodnet is used in certain high availability utilities, such as package control scripts and SGeRAC utility scripts for VIP management, to add or remove an IPv4 or IPv6 address to or from network interface connected to the subnet identified by subnet_name. In addition, cmmod- net can be used to check if an IPv4 or IPv6 address can be added to the given subnet identified by subnet_name. cmmodnet can also be used to disable or enable a LAN interface currently configured in a cluster. HP-UX examples of LAN_name can be lan0, lan1; Linux examples of LAN_name can be eth0, bond0. This command simulates a LAN interface failure or recovery in the cluster without changing the physical status of the interface. cmmodnet requires the user be a superuser(UID=0) or have an access policy of FULL_ADMIN allowed in the cluster configuration file. Non- superusers may only use this command to remove IP addresses. See access policy in cmquerycl(1m) or cmmakepkg(1m). Extreme caution should be exercised when executing this command (for puposes other than checking) outside the context of a package control script or SGeRAC utility script. In this capacity it should only be used to remove the relocatable IPv4 or IPv6 addresses of packages which have failed and are in the "halted" state or to disable and enable a LAN interface when absolutely necessary. Using it while the package is running could lead to loss of client connectivity. The user needs to make sure that an IPv6 subnet must be either site-local or global and must not be link-local. Options cmmodnet supports the following options: -v Verbose output will be displayed. -a Add the IPv4_address to the IPv4_subnet or add the IPv6_address to the IPv6_subnet -r Remove the IPv4_address from the IPv4_subnet or remove the IPv6_address from the IPv6_subnet -t Check only. Checks if the IPv4_address can be added to the IPv4_subnet or checks if the IPv6_address can be added to the IPv6_subnet -i IPv4_Address or IPv6_address Use the IP address given for the operation. This is a required parameter. -d Disable LAN interface configured in the cluster. This option simulates the LAN interface failure without actually bringing the interface down. There is no immediate effect if the LAN interface is already disabled or physically down. This option allows failover of IP addresses configured in this LAN interface to an available standby interface (HP-UX only). If no standby is available (HP-UX and Linux), the subnet(s) on this interface will virtually go down and packages monitoring the subnet(s) will be brought down or switched to another node; in the worst case a TOC could result if this is a failfast package. This option also implies that there is no effect on recovery of IP addresses and subnet(s) on this LAN interface if the physical status of the interface changes at later time. -e Enable LAN interface configured in the cluster. This option simulates a LAN interface recovery from previously disabled state. There is no immediate effect if the LAN interface is already enabled or physically down. RETURN VALUE
cmmodnet returns the following values: 0 Successful completion. 1 Command failed. AUTHOR
