04 Oct 18 Glance/midaemons wont start
Troublehooting steps:
1- Remove the /var/opt/perf/ttd.pid and try to start glance again
#rm /var/opt/perf/ttd.pid
#glance
2- If the above fails to fix it then stop and restart Glance as follows
# mwa stop
# midaemon -smdvss 4M -kths 1000 -pids 5000 -p # ps -ef | grep midaemon Make sure the midaemon is running, # mwa start
Modify MWA_START_COMMAND variable in /etc/rc.config.d/ovpa as follows to keep the changes across system reboot.
# grep MWA_START_COMMAND /etc/rc.config.d/ovpa MWA_START_COMMAND=”/opt/perf/bin/midaemon -smdvss 4M -kths 1000 -pids 5000 -p ; /opt/perf/bin/mwa start”

28 Nov 17 An xpinfo that works in hpvm guests and on non Hitachi storage
Hitachi shops faced annoyance times two:
1. xpinfo does not work on non-Hitachi storage for example Pure storage
2. xpinfo does not work on hpvm guests depending on how the storage is passed through from the hpvm host
I now present xpinfonew which though raw and unfnished
The output:

01 Aug 17 Need a longer hostname 8+ Don’t forget the kernel parameter
Host names need to be descriptive. The trend toward longer names has been going on for years.
As a legacy Unix, HP-UX CAN keep up.
kctune -v expanded_node_host_names
mygush0:root > kctune -v expanded_node_host_names
Tunable expanded_node_host_names
Description Enables expanded node and host names (read manpage for warnings)
Module sysconfig
Current Value 0 [Default]
Value at Next Boot 0 [Default]
Value at Last Boot 0
Default Value 0
Constraints expanded_node_host_names >= 0
expanded_node_host_names <= 1
Can Change Immediately or at Next Boot
hostname is set in /etc/rc.config.d/netconf
But to make the system fully compatible the kernel needs to be set.
mygush0:root > kctune expanded_node_host_names=1
==> Update the automatic ‘backup’ configuration first? y
* The automatic ‘backup’ configuration has been updated.
* Future operations will update the backup without prompting.
WARNING: Setting the expanded_node_host_names parameter to 1 will allow
administrators to set node and host names larger than 8 and 64
characters/bytes, respectively. It is strongly recommended
that all related manpages and documentation be understood
before setting larger names. Larger names can cause some
applications which use those names to behave incorrectly or
fail.
* The requested changes have been applied to the currently
running configuration.
Tunable Value Expression Changes
expanded_node_host_names (before) 0 Default Immed

28 Apr 17 Handle with care: TCP wrappers /etc/hosts.allow
Real life story.
DMZ based server dedicated to SFTP was configured with sshd rules in /etc/hosts.allow
sshd : ALL@16.89.97.*:ALLOW
sshd : ALL@14.251.*:ALLOW
sshd : AAL@208.94.61.*:ALLOW
Should have been:
sshd : ALL@16.89.97.*:ALLOW
sshd : ALL@14.251.*:ALLOW
sshd : ALL@208.94.61.*:ALLOW
That network was the firewall to the outside world.
The end users were inconvenienced and the firewall team wasted a lot of time reviewing rues and looking at logs.
