Re: [SunRay-Users] dhcpmgr for RHEL5?
hm there's no such specific tool like dhcpmgr however I guess - you can edit the file (/var/lib/dhcpd/dhcpd.leases and then restart dhcpd (/etc/init.d/dhcpd restart or service dhcpd restart) - take a look at webmin, it's a nice webmanagement tool that can be installed on top of EL. (and it's free). it's basically a whole bunch of PHP modules to help manage the services. it's a bit heavy weight for just doing dhcp however it lets you do what you want I think. it contains some code to delete leases from the lease database.

What do you mean by "release dhcp instances"? Is there something unusual about your network that causes you to have to do that manually? The ISC DHCP server used in RHEL doesn't have an admin GUI. It doesn't even have an admin CLI. Administration is performed by editing configuration files and then manually restarting the server. The SRSS 'utadm' and 'utfwadm' scripts hide most of this, but if your network requires you to periodically go in and poke things then you're probably going to have to knuckle down and fire up a good old-fashioned text editor to do that.

Re: [SunRay-Users] Increasing max-shm-ids on Solaris 10 ....
You can still use /etc/system in Solaris 10 /etc/system (requires reboot)... add this: set shmsys:shminfo_shmmax=1048087 set shmsys:shminfo_shmmin=1 set shmsys:shminfo_shmmni=4096 you can do it with resource control as well, but then you have to deal with projects, etc. I confess to not being an expert in this area of functionality on Solaris, but you can read about it with prctl(1), and projadd(1M) commands. You use prctl to set the value for the session, and then projadd to make it persistent. I am not sure if/how this works, but for example, if all your users (check with id -p) belong to the project 'default', then you can run these commands as root to increase the values the same as if you used the (obsolete, supposedly) /etc/system method above: prctl -n project.max-shm-ids -v 4096 -r -i project default prctl -n project.max-shm-memory -v 4gb -r -i project default I have no idea what the appropriate projadd syntax would be to make that persistent.

[SunRay-Users] Flash player colour mask problem - can this be fixed in SRSS ?
Since Adobe havn't able to fix the color masks for flash player 10.1, how much trouble would it be for it to be changed on the Sun Ray X server, so that it uses the 'red, green, blue = 0xff, 0xff00 0xff' colour masks that Adobe assumes. Perhaps this could be an option for utxconfig. - Murray ___ SunRay-Users mailing list SunRay-Users@filibeto.org http://www.filibeto.org/mailman/listinfo/sunray-users

Re: [SunRay-Users] Strange disk redirection problem
On Linux the disk needs to be sync'd and unmounted before being unplugged. This is because Linux does not flush its write buffers unless told to, even though it is mounted with the 'sync' option. I suspect there is no correlation to the Windows machine and the behavior difference you see could be coincidental. There is no way to unmount from within windows. You can run "utdiskadm -r" on Linux to unmount the disk.
