Thanks, So one more question if you please... I seem to recall reading something to the effect of Labeled IPSEC only working between two or more Linux/SELinux systems. Can Labeled IPSEC be configured to apply static labels to incoming packets?

While the RHEL5.x kernels have NetLabel support, it is very basic as it predates most of the labeled networking improvements that have been made in the past years. Unfortunately, this means that the fallback/static peer label feature is not part of RHEL5. > Also I currently have separate ssh daemons running at certain > sensitivities (runcon) and bound to specific IP addresses (separate > sshd_config files). Will fallback labeling impact my ssh setup? You'll need to be more specific about what you mean by "impact". Will NetLabel affect how you bind the multiple SSH daemons? No. Will NetLabel affect how the SSH daemons are labeled? No. Will NetLabel allow you to assign peer labels to incoming SSH traffic? Yes. Will this mean I'll need to change my SELinux policy to add the necessary controls? It depends. > -----Original Message----- > From: Paul Moore [mailto:paul.moore@xxxxxx] > Sent: Tuesday, April 13, 2010 5:55 PM > To: Benedict, Phillip M > Cc: Michal Svoboda; selinux@xxxxxxxxxxxxx > Subject: Re: MLS telnet question > > On Tuesday 13 April 2010 12:42:36 pm Michal Svoboda wrote: > > Benedict, Phillip M wrote: > > > The network does not carry any cipso data for evaluation by my > > > server, so I don’t think I can use netlabel. > > > > You can use the fallback label feature that can assign labels > > statically per remote IP. > > NetLabel fallback/static label example configuration: > > * http://paulmoore.livejournal.com/1758.html -- paul moore linux @ hp -- This message was distributed to subscribers of the selinux mailing list.
