First, The Consultant
Recently I was working with another “consultant”. I’ve deliberately put that in quotes because this person really lacked the skills to do the job he was doing, but for political reasons I had to refrain from pushing him out of the way and taking over. His lack of basic knowledge was frustrating, but I gritted my teeth and kept my comments friendly. It wasn’t easy.
Anyway, part of what he was doing was configuring a router. I had to hold my breath as he explained that he always left the default password unchanged because “it’s easy to remember”. After he left, and with the permission of the owner, I changed that. It’s just this funny idea I have that a router sitting on the Internet ought not to have a password that is known by a few million people and published on hundreds of websites. I’m funny like that.

SCO Openserver release 5.0.7
Disclaimer
There is a lot to like in the 5.0.7 release of SCO Openserver. Support for IDE CD-RW and DVD-RAM (you need other tools to actually write to this media, but the important kernel support is built in), more USB devices (though not printers or modems), P4, Xeon, and AMD Athlon processors, UDMA 100 and 133 hard drives, PCI serial and parallel cards, LS-120 and LS-240 IDE drives (see “man Sflp”, not “sflp” as the documentation suggests) , several Gigabit network cards, and more PCMCIA support.
The Netscape server is gone, replaced by Apache, OpenSSH is built in, sendmail is at 8.11 (which of course will need immediate updating), and you now have a choice of Mozilla or Netscape for GUI browsers and Lynx is included for character mode.

Why Production servers shouldn’t have external interfaces

People sometimes want to use their application servers as firewalls. This seems attractive at first glance: slap in another network card, add some packet filtering, tighten the system down a bit and connect it to the outside world. Cheap and quick, but a very bad idea.
