Operating Systems AIX disabling telnet login for root only Post 302227018 by otheus on Wednesday 20th of August 2008 11:34:11 AM

The easiest, portable way is to use the tcpd/tcp_wrappers library by Wietse Venema. With this, /etc/services does not contain the telnetd program directly, but a line that invokes the program "tcpd" which in turn checks the files /etc/hosts.allow and /etc/hosts.deny. In these files, you can set policies however you desire (per process, per user, per source host).

Do a man on hosts_access (5).

NAME
fence_drac - fencing agent for Dell Remote Access Card SYNOPSIS
fence_drac [OPTION]... DESCRIPTION
fence_drac is an I/O Fencing agent which can be used with the Dell Remote Access Card (DRAC). This card provides remote access to control- ling power to a server. It logs into the DRAC through the telnet interface of the card. By default, the telnet interface is not enabled. To enable the interface, you will need to use the racadm command in the racser-devel rpm available from Dell. To enable telnet on the DRAC: [root]# racadm config -g cfgSerial -o cfgSerialTelnetEnable 1 [root]# racadm racreset fence_drac accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_drac can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts. Vendor URL: http://www.dell.com OPTIONS
-a IPaddress IP address or hostname of the switch. -c cmd_prompt Force fence_drac to use cmd_prompt as the command prompt -d dracversion Force fence_drac to treat the device as though it was for the specified drac version -D dumpfile Debug file of the telnet interaction -h Print out a help message describing available options, then exit. -l login Login name. -m modulename The module name of the blade when using DRAC/MC firmware. -o action The action required. reboot (default), off, on or status. -p password Password for login. -S path Full path to an executable to generate the password for login. -f seconds Wait X seconds before fencing is started -V Print out a version message, then exit.
