apache as a web proxy

rdircio

if you want a quick web proxy for your browsers or for anything, you can define a virtualhost in apache2 as follows:

Listen *:8080
<VirtualHost *:8080>

ProxyRequests On
ProxyVia On

<Proxy *>
Order deny,allow
Allow from all
</Proxy>

CacheRoot "/tmp"
CacheMaxExpire 24
CacheLastModifiedFactor 0.1
CacheDefaultExpire 1
ServerName my-proxy
ErrorLog "/opt/csw/apache2/var/log/proxy-error.log"
CustomLog "/opt/csw/apache2/var/log/proxy-access.log" common

</VirtualHost>

Make sure you have the dscp addresses configured in the xscf

XSCF> showdscp

To enable the internal network nic sppp0 in a domain:

svcadm enable svc:/platform/sun4u/dscp:default

To enable the dynamic reconfiguration in a domain:

svcadm enable svc:/platform/sun4u/dcs:default

See the sppp0 nic with the address

sppp0: flags=10010008d1 mtu 1500 index 8
inet 192.168.224.6 –> 192.168.224.1 netmask ffffff00
ether 0:0:0:0:0:0

a test to see if communication is ok, from the XSCF run:
XSCF> showdevices -d 0

Remove disks from vxvm control in a m9000 for dynamic reconfig

rdircio

If when you want to remove a XSB from a domain you get the message that the OS disks are being used by VxVM, and you know they’re not:

XSCF> deleteboard -c disconnect 09-0
XSB#09-0 will be unconfigured from domain immediately. Continue?[y|n] :y
Start unconfiguring XSB from domain.                                               Resource              Information
------------------  -------------------------
/dev/dsk/c1t0d0s2   Device being used by VxVM
/dev/dsk/c1t1d0s2   Device being used by VxVM
XSB#09-0 could not be unconfigured from DomainID 2 due to operating system error.

The message “Device being used by VxVM” can be a bit misleading. They are not in use by VxVM, they’re in use by VxDMP!!!!

To remove this dependency you need to remove them from dmp by doing something like:

vxdisk -o alldgs list | egrep '^c0|^c1' | awk '{ print $1 }' | while read d;do vxdmpadm -f disable path=$d; done

After this you can remove the XSB using “deleteboard -c disconnect” without the “device being used by vxvm” error message :)
