mount server reported tcp not available, falling back to udp

rdircio

If your nfs client has this:
# mount /usr/sap/trans
mount server reported tcp not available, falling back to udp
mount: RPC: Program not registered
and this:
# rpcinfo -p nfsserver
No remote programs registered.
you may have tcpwrappers in the nfs server, so, in the nfs server edit /etc/hosts.allow and add:
portmap : usdaapp151,10.21.40.100 : ALLOW
portmap : ALL : DENY
nfs-server : 10.21.40.100 : ALLOW
nfs-server: ALL : DENY
do not restart anything, just mount your filesystem in the client

stream a webcam, using highly compressed h264 instead of typical mpg

rdircio

Got a logitech webcam c300, it uses the “uvcvideo” kernel module.
Typically you would grab video using “motion” and stream it on mpeg, well that’s rubbish if you want better
compression, so let’s do it using the best of the best: h264.
#!/bin/ksh
DEV=/dev/logitechcam
ps -ef | grep -i vlc | grep -v grep |grep -i logitechcam | awk ‘{ print $2 }’| while read P;do
kill -9 $P
done
VLC=”/usr/local/bin/cvlc v4l2://$DEV :input=2 :input-slave=alsa://hw:2,0 –alsa-samplerate=32000
–v4l2-controls-reset –v4l2-auto-white-balance=1 –v4l2-do-white-balance=1 –v4l2-autogain=1 –sout ”

CAM=”transcode{vcodec=h264,acodec=mp4a,width=320,height=240,vb=64,ab=24,channels=1,venc=x264}:standard{access=http,dst=0.0.0.0:8090/stream.flv}”

#CAM=”transcode{vcodec=mjpg,width=320,height=240}:duplicate{dst=std{access=http{mime=multipart/x-mixed-replace;boundary=–7b3cc56e5f51db803f790dad720ed50a}.mux=mpjpeg,dst=0.0.0.0:8090/m.mjpg}}”
${VLC} “#$CAM”
this produces a very decent quality stream at around 100kbps, audio also included!
Enjoy!

copy dvd on solaris10 to an image
I’ve copied and used a DVD image from the eiscd DVD (enterprise installation standards), to add it to my remote
JET(jumpstart enterprise toolkit) servers using:
1- insert the dvd in the drive
2- observe the mountpoint (cxtxdx)
# df -k | grep cdrom
/vol/dev/dsk/c0t1d0/eis-dvd 2290588 2290588 0 100% /cdrom/eis-dvd
3- Stop volume management, because it prevents from reading from the raw device
# /etc/init.d/volmgt stop
4- Use dd on slice 2
# dd if=/dev/dsk/c0t1d0s2 of=/eisdvd.iso
5- transfer eisdvd.iso to other machine, and test:
# mkdir /eis
# mount -F hsfs `lofiadm -a /eisdvd.iso` /eis
Success!

Use hpasmcli to diagnose your HP hardware

rdircio

To check your hardware for failures, if you have hpasm installed:
# hpasmcli -s “help show”
USAGE: SHOW [ ASR | BOOT | DIMM | F1 | FANS | HT | IML | IPL | NAME | PORTMAP | POWERSUPPLY |
PXE | SERIAL | SERVER | TEMP | UID | WOL ]
# hpasmcli -s “show dimm”
# hpasmcli -s “show fans”
# hpasmcli -s “show iml”
# hpasmcli -s “show powersupply”
# hpasmcli -s “show server”
# hpasmcli -s “show temp”
