Oracle extends Support for Solaris 10 and 11.3 to 2027

Oracle has once again changed the Extended Support for Solaris 10 and Solaris 11.3
from January 2025 now to January 2027.

Impact of new openssh 9.3p1 on Solaris 11.4.60

When connecting to an old server you may see

-bash-5.2$ ssh g0083
Unable to negotiate with 192.168.100.83 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss

or if you try to connect from an old system to Solaris 11.4.60 or newer

-bash-4.4$ ssh g0049
no hostkey alg

This is because the new openssh version on Solaris 11.4.60 has sha-1 hash disabled by default.
It is recommended to update your old systems to newer versions.

On Solaris 11.3 you need to:
pkg install openssh
pkg set-mediator -I openssh ssh

If this is not possible as a workaround you can enable sha-1 on the new Solaris server
for the target systems in /etc/ssh/ssh_config and/or sshd_config

Host g0083
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa

Overview of Solaris ZFS blog posts

I wanted to write a blog post about ZFS encryption and found
there was already a post in 2020.

It looks like it's time for an overview about such posts

I/O experiences with Solaris X86 on OCI

Ultra High Performance(UHP) block volumes can't be attached to Solaris
at the moment using ISCSI. This type of volume can only be attached
paravirtualized to a VM.
The volume should be able to handle 1200MB/s.
The maximum I could reach on a large VM was 750MB/s.

Best solution seems to use Balanced with Auto-tune.
I/O limits are based on the volume size, for example
for a 50GB volume the limit is at 30MB/s

Highest for a 1TB volume is around 600MB/s on bare metal.
On a large VM I could reach the same 600MB/s. Looks like
the virtualization layer has no impact on the performance.

On smaller VMs the performance is limited
by the network speed and the number of CPUs.
With 2 cores the maximum I reached was around 250MB/s
