		<description><![CDATA[Last week (well it was last week when I started writing this) we had an issue come into the CAC where someone wanted to write a command macro that ran telnet to log into a system and execute some commands, for example the command macro test.cm logins into a remote host and executes the foo.cm [...]]]></description>

		<description><![CDATA[About 18 months ago I wrote a blog talking about changes in how accept works in OpenVOS release 17.1. What I neglected to indicate was that these changes only take effect if the application code is POSIX based. To recap, prior to 17.1 STCP would only reply to a client connection request if the server [...]]]></description>

		<description><![CDATA[If you have ever tried to use POSIX-based programs to process VOS structured files, you may have encountered some restrictions or seen some behavior that you didn&#8217;t understand. In this post I will try to explain what&#8217;s going on. VOS supports 4 types of files: sequential, relative, fixed, and stream. The first 3 formats are [...]]]></description>

		<description><![CDATA[The maintenance network is used by OpenVOS for monitoring several devices including the RAID and SAN disk arrays. This network also allows you access for making configuration changes, debugging problems and general monitoring. However, when accessing these devices from the OpenVOS module you can only use the command line interface (CLI); the friendlier, graphical user [...]]]></description>

Every call to the socket function results in STCP creating a new clone of the stcp device. [...]]]></description>

		<description><![CDATA[A lot of locations are mandating that you stop connecting to the system with Telnet, and use SSH instead. The rationale is greater security. When you log in using Telnet your password, as well as any other data, is sent in clear text. Anyone with a network analyzer can read what you sent. SSH, on [...]]]></description>

		<description><![CDATA[There has been a fair amount of confusion over the difference between the host file and hosts (plural) file. Both files should be in the &#62;system&#62;stcp directory but there the similarity ends. The hosts file is used for IP address to name resolution. Depending on your configuration you may or may not need a hosts [...]]]></description>

The topic is not number theory but socket programming and a coding mistake that I have seen way too often. The code fragment in figure 1 demonstrates the mistake. There is a main while loop that loops forever calling select and waiting for [...]]]></description>
