It is possible to create pseudo devices that enable a UCX host to have more than 1 IP address. A pseudo device is created which has a letter between the 2nd and 3rd character, e.g. sea0 is a pseudo device for se0. Could have sea1, sea2 etc. The a means it relates to physical device 0, b means 1 etc. To create a pseudo deviceUCX> set init sea0/host=200.200.245.3/net=255.255.255.0/broad=200.200.245.255 Also would need to do config to make addition permanent To make a machine a routerUCX> set protoco ip/forward UCX> stop routing UCX> start routing/supply Permanent UCX> set config start routing/supply UCX> set config ip/forward GatewayTo configure a gateway UCX> set route <addr with 0 where appropriate>/gateway=<addr>/perm UCX> set route 158.234.24.0/gateway=158.234.24.1/perm Creating and Deleting$ telnet/create <ip address> <listener> <number of tna> e.g. $ telnet/create 172.20.1.24 2004 11 would create tna11: on ip 172.20.1.24 using listener 2004 $ telnet/delete <number of tna> e.g. $ telnet/delete 11 TCP/IP trace$ tcpiptrace/full xxx.xxx.xxx.xxx /port=remote=<listener> /protocol=ip /packets=100 By default 100 buffers are used, but if more are needed can use /buffers=200 Also when using trace need to increase WSQuota to 2048, and may need to logout if a trace fails as it does not free up resources.

The above attack can be stopped if the system manager creates a file called SYSUAFALT.DAT which is the file used when uafalternate is set to 1. A more general break in is to perform a conversational bootup, and type set startup opa0: , and type spawn which will then allow you to have the SYSUAF file before anything else starts.
