Security → Re: Help: trls32.net and TCP port 61899

I doubt a Riverbed steelhead would have local access to a computer unless you were administering the console for it from that box. However you hint at not being aware of a Steelhead on your network.

The only other item for that port initially seems to be:
Xsan is Apple Inc.'s storage area network (SAN) or clustered file system for Mac OS X

Guess Wireshark will at least give you a little more info.

This is my home network. I know everything on it and there's no "Steelhead".

Seems like no-one can find anything other than that I've found myself.

Wireshark hasn't captured anything yet. Guess I'll leave it running...
