There are actually quite a few no cost TFTP server software program plans that do the job pretty well just enter cost-free tftp server into Google or your favorite internet search engine and youll see what I suggest.
Using TFTP With this trend is a terrific way to have backup copies of IOS pictures or router configs proper on the laptop. And take it from me, when the day comes that you simply require These backups, youll be happy you probably did!
