Paul Green and I were discussing a new command he’s working on called check_module_security. The subject of unnecessary commands available at the login prompt came up. Jon Schmidt of Transaction Design recommends in an article about Locking the Barn Door.
Starting in release 13.2 VOS has offered the ability to configure a fault tolerant IP interface by configuring active/standby Ethernet adapters.
An SSH tunnel can be used to secure communication between a client and server that cannot otherwise be secured.
Something that people moving from TCP_OS to STCP notice right off the bat is that the set of TCP statistics displayed by the TCP_OS netstat command is quite a bit richer than that displayed by STCP.
Sometimes netstat will show a socket that appears to be stuck. The remote application has been terminated, sometimes even the OpenVOS application has been terminated but netstat is still showing the socket. This article will explain why this happens and what you can do about it.
Every now and then someone asks the following question “We added our application port to the services file and now some other application is using it – why”. The answer is because the services file does not reserve port numbers.
More and more security and network administrators are prohibiting the use of telnet. Unfortunately, the Stratus RSN requires that the Stratus module run a telnet server.
A multihomed system is a system with multiple IP interfaces. These interfaces can be on the same or on different subnets. Today I want to consider protocols like FTP and NDMP.
First a little background, TCP has a concept called maximum segment size (MSS). This is the largest segment (of data) that the TCP stack will accept.
