.serverauth was deleted
Dear All,
I was realized that my /home/user/.serverauth was deleted and unable to start xfce4 anymore. Perhaps this is a sign of intruding. I had no idea how. I had issues this command tcpdump -l npi fxp0 | tee tcpdump to analyze the network traffic. I had realized there are a lot of ipv6cp and lcp packet flowing between the interface. I had attached a tcpdump file with a idle connection. Hope someone are willing to illustrate this. |

Peter, any time something happens you do not understand, it must be "I've been hacked!"
Please stop. You. Have. Not. Been. Hacked. You do not know what a .serverauth file is for, how it would be created, nor deleted. I'll tell you this much. These files are created by startx(1), and deleted by startx(1). Perhaps it was your failed Gnome installation that is causing your problems now? We don't know, of course, because you haven't posted a useful problem report. Since you've posted some tcpdump(1) output, I looked at it, and saw:

If you do not have the skills to maintain your own system, consider using M:Tier's very useful -stable services. Many people do, for both -stable systems and -stable packages. Last edited by jggimi; 25th August 2015 at 12:46 PM. Reason: clarity, formatting |

I think your issue here is in the pursuit of a "sense of security" rather than actual security. As jgimi says, files like .serverauth.* and .Xauthority are session files which work exactly as above. Things can go wrong with these when X is just killed or if the user just reboots from a terminal emulator. This means that next time you want to run startx, you may need to clean up. I thought that on your system the X aperture driver was disabled and the X sets not installed anyway? |

It's OK to have a sense of paranoia, if it is applied constructively towards best practices. This isn't.
Peter's paranoia appears actively harmful to him, because his focus and attention are on non-existent threats. He apparently has no time or attention to spare to learn and apply actual security best practices, such as keeping his system up-to-date. |

I'm understand what you all saying here. I will try my best to follow the guidance and practises from experience people. Thanks you very much.

Excellent! I know that you want to "harden" your OpenBSD installation. Your first step towards actually doing that is to apply fixes for known issues. As noted above, there are nine security issues you have not yet addressed.
OpenBSD is source-code maintained. Users -- that's you and me, Peter -- are expected to be able to apply patches or else build a system from the -stable branch (the "patch branch") of the source code. The errata web page linked to above provide step by step instructions for individual patches, but there is an assumption that the user has read the FAQ and obtained the -release source code. If you find this is beyond your skills, you can use M:Tier's -stable services. While not part of the Project directly, M:Tier employs several OpenBSD developers and provides commercial OpenBSD services. Along with -stable systems, M:Tier also provides -stable packages. The OpenBSD project creates -stable ports but does not have the resources to provide -stable packages for all of its architectures, leaving the building of packages to the users. Many users, even technically skilled users, use M:Tier's service because they do not have the time, resources, or interest in building -stable packages for themselves. Good luck! Should you have any questions about keeping your system updated, please start a new thread. If you still have issues with XFCE, and wish to have us review the problem, please post a more complete problem report. If you're unsure what to post, log the output of your startx(1) command. $ startx > my.log.file 2>&1 should log the startx output into my.log.file. If there is content, it may show the error more clearly. And it may provide you with enough information to resolve the problem on your own.
