Dump a Communications Trace was a blog I wrote back in 2009. That article reviewed the support for dumping the trace data in “packet capture” (PCAP) format and hinted that the DMPCMNTRC command would likely be updated to support this feature (without the need for a data area).

Way back in V5R1, IBM introduced the ability to route FTP and SMTP workloads to their own subsystems. By default, FTP and SMTP server jobs run in the QSYSWRK subsystem, along with a lot of other IBM i server jobs. The Server Table in the IBM i Knowledge Center documents all the IBM i server jobs along with the default subsystem in which they run. The server table does state the subsystem is configurable for these servers, but it doesn’t give you any more information.

When security algorithms are deemed vulnerable or another network attack is disclosed, how do you know if you’re impacted? How many issues could be caused by turning a weak security algorithm off? Tracing network traffic and analyzing the data is a tedious task and isn’t always straightforward.

IBM i 7.2 support of Virtual LAN allows using a single adapter to connect to multiple VLANs. If your system must connect to multiple VLANs, this support can allow you to reduce the number of adapters needed or add redundant network connections without adding additional adapters.

The IBM i 7.2 release is absolutely loaded with new System SSL capabilities. There are a couple major new features only available starting with the 7.2 release. There is also a subset of the 7.2 capabilities that escaped from the Rochester development lab last year as part of 7.1 TR6. The early content was baked into 7.2 before it found its way to 7.1. February’s System SSL blog remains relevant as the discussion turns to the 7.2 release. What you’ll notice for that content is how and when the new function is enabled has changed with the 7.2 release boundary.
