Error in z8 upgrade

I copied all of .zcash/testnet3 from another computer that was connecting, and now it is connecting. Yea. Will I be able to do that on the real thing without messing something up?

I did an install and during the first time I tried to mine it started, but also then on my command line (not under it) it gave an error code “cannot obtain a lock” on testnet3, “bitcoin core is probably already running”. It only happened on the first run. I had seen it before and wonder if that’s where the lack of getting a connection begins.

What makes alphatestnet.z.cash able to provide a connection to other computers participating on the testnet? Can anyone else offer their computer as a publicly available node for this purpose?

There is nothing special about alphatestnet.z.cash other than that the Alpha Guide recommends adding that node in your zcash.conf.

The problems with connecting to the testnet are caused by this issue: Decrease MAX_HEADERS_RESULTS · Issue #1289 · zcash/zcash · GitHub , which will be fixed by z9, due to be released today.
