Multihomed hosts and /etc/hosts
As a side note to looking up hostnames from IP addresses for people who use /etc/hosts , note that /etc/hosts lookups work badly in the presence of hosts with multipleIP address, since most gethostbyname() implementations will onlyreturn the first IP address that they find in /etc/hosts . These daysyou really want a minimal /etc/hosts and a reliable DNS server, unlessyou have special concerns .
(The gethostbyname() behavior is sensible, since otherwise it wouldalways have to
Getting a useful persistent VNC session
By a persistent VNC session, I mean a session that you can connect yourVNC viewer to, do stuff, disconnect from, and then later come back toconnect to it again. This makes it the graphical equivalent of screen , at least for me.
(Much like screen , it also gives you a certain amount of immunityagainst network and workstation stability problems for critical tasksthat you don't want interrupted. More and more, systems have to bemanaged graphically instead of through text interfaces, which means that

偶然發現上司Eric的房間掛著一則「辦公室禱文」:
“Grant me the wisdom to hide the bodies of those people I had to kill today because they pissed me off, and help me to be careful of the toes I step on today, as they may be connected to the ass that I may have to kiss tomorrow.”
老實說,我的確嚇了一跳。一直以為Eric的交際手段
A thought about Solaris 10 x86's boot process
In succinct form:
The problem with Solaris 10 x86's boot process is not so much that itis trying to pretend that it has OpenBoot, the problem is that it isdoing such a clumsy and awkward job of faking it.
I will admit that I am not a fan of the Solaris 10 x86 boot process. Iunderstand why it is trying very hard to pretend that it is just likeSPARC hardware with OpenBoot, and I can even sympathize with Sun'smotivations for

Virtualization does not eliminate security concerns
Here is something that has struck me recently: virtualization andabstraction cannot eliminate security concerns, they can only move themfrom one place to another . In other words, virtualization by itselfdoesn't do anything to prevent security bugs; it just means that theyhappen in a different place.
(By virtualization I mean more than hardware and OS virtualization, Ialso include things like the JVM.)
The advantage of virtualization is that it moves the problem inwards,towards the center of the security onion, where fewer people
