If you need to upgrade a Ubuntu with LAMP from 17.04 to 17.10, you need more time due to php upgrading.
Php 7.1 will be installed to replace 7.0. Lots of mods, as well as fpm, need to be reconfigured.

I have multiple devices installed with Ubuntu Server. Some of them have a strange problem:
They can access internet using some applications, such as squid, without any problem.
They can ping to internet IP address.
They can use host / dig to query IP by domain name.
They cannot ping to internet by using domain name directly.
They cannot download file through wget / curl using domain name, but can do with IP.
They cannot use apt, stuck at connecting.
All they use a local dnsmasq as their dns.
After a long time dig, I found the problem and here is the fix.
open the file /etc/nsswitch.conf, search the line with “hosts:” and change the setting to “files dns” (without quotes).
While I’m trying to deploy my site from Visual Studio to a Windows Server 2012 R2 instance, I have to dig a lot for troubleshooting about Web Deploy related problems.
Here are some not listed in Microsoft documents:
This will guide you to prepare a installation media from Windows and install ubuntu into Soekris net6501.
Stuffs you need:
Prepare installation media:
Install:
install console=ttyS0,19200
Finalize:
Grub configuration need to be adjusted for using serial as console.
Edit /etc/default/grub and change to these lines below:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="console=ttyS0,19200 noplymouth"
Then run update-grub.
Hope this help you.
Microsoft fixed the problem about Windows Update working with WSUS, finally after nearly 2 months.
In our company, our major productive servers are hosted in vSphere as Windows-based virtual machines. Some of them need very big disks. Through the largest disk space supported in vSphere is 16TB (or maybe more, i dunno), I’m not interested to create such a big file in VMFS. It will be really a pain your *** when you have to move such a big file among datastores, even among data facilities by using portable hard drives.
Creating smaller disks instead of a big one for every Windows-based VM, IMHO.
Fortunately, Windows support to merge small disks as a big one, using dynamic disk function. There are 4 kinds of volume can be supported in such a condition: Spanned, Striped, Mirrored and RAID-5. You can consider them like JBOD, RAID-0, RAID-1 and RAID-5 functions in a simple legacy storage device.
Because data protection is existed in the SAN, Mirrored and RAID-5 volumes are not considered at all. Striped will make it a little faster when lots of virtual disks fight for limited IOPS resources within one datastore. But there is no way to extend any stripped volume (https://technet.microsoft.com/en-us/library/cc770938.aspx).
So, the useless volume format in a traditional world, spanned volume, is the best solution, maybe the only one. Next time when you need to create big virtual disks for Windows in any virtualization environment, don’t forget to consider using Spanned Volumes.
After several weeks testing, I’m sad to tell you all that at least currently, Windows 10.0.14394 (aka 1607) still cannot work with WSUS.
Problem: If there is Windows related package push from WSUS, svchost processes on Windows clients keep crashing.
