Solaris

Have you tried to remove the software you installed before everything went south? Also have a look if this helps:

I did try to uninstall using make uninstall as instructed in the documentation of the software, but that unfortunately did not work.
Trying to troubleshoot the service according to your link did not work either.

Since the snapshots of my rpool are before I configured the zones and services and with the possibility of an existing bug that makes my machine unreachable in 11.3 I have decided to do a clean install of 11.1 and set everything up from the beginning while my memory of it is fairly fresh. I made some configscripts this time when I installed everything which will help me set things up fairly quickly as well.

Even if I manage to fix this with the help of you guys, I won't fully trust it not to happen again. And not least, I need this machine up and running and troubleshooting it takes too long.

Lesson learned: turn on timeslider the first thing you do and be generous with snapshots before doing stuff.
It's just easy to forget those things when 11.1 was rock solid for several years.

Thanks anyways for trying to help me as much as you have.

@Zorken.......Out of curiosity can you please post the make/model/chipset of your network card/interface. This being a network issue I've often wondered whether this problem might be chipset specific. Thanks.

For the record, I have the most problem with a built-in Broadcom NetXtreme BCM5721 Gigabit PCI Express chipset. If I want to avoid trouble I avoid the current Solaris 11.3 Live DVD install media.

My network adapter is a built-in Realtek 8111 Gigabit LAN controller, residing on a ASUS M4A88T-M motherboard.

I installed Solaris from a USB stick using sol-11_3-live-x86.usb downloaded from oracle.com.

Thanks, that's useful to know. So it's not chipset specific then.
