nddconf in virtualvault 4.5

Hello

I am working with Virtualvault 4.5 (VVOS HP-UX B11.04) but i don't know if the nddconf file can work with +10 parameters.
In HP-UX 11.0 isn't posible but if you install a patch it is posible.
Could somebody tell me if the nddconf file support +10 parameters in virtualvault 4.5? Thanks

Simon,

I can't answer for the VV, becuase I replaced over a dozen of them with a Bastion Host making my environment much more secure and at the same time flexible enough that developers weren't hindered by the TGP. Additionally I am able to run my web services on virtually any platform and HPux Revision, and receive and apply patches as they come available. I no longer have to wait for the VV team to retrofit the necessary security patches. If you stay with VV, then you will have to put your own ndd commands into the network startup script, but make sure you read the following:


From http://people.hp.se/stevesk/bastion11.html

Some of the default values match our preferred value, but we can choose to set them anyway, just in case the default should change in a future release. ndd supports a -c option which reads a list of tunables and values from the file /etc/rc.config.d/nddconf, and which is run automatically at boot time. However, there are some problems with the default setup. First, at the time of this writing, ndd -c is only able to handle 10 tunables in nddconf. Next, ndd -c is run at the end of the net script, which is after network interfaces have been configured. One issue with this is it is too late to set ip_check_subnet_addr if we are using subnet zero in the local part of a network. But more importantly, we want to set tunables before the network interfaces are configured (note: the ordering problem has been fixed in a recent transport patch, but the 10 tunable limit remains).
