writing to tape

by Brad Noyes

Hi All, I trying to write a program that will write to tape, but i can't seem to get it to work correctly. i have attached a simple piece of source code that will open a file (or device) and write the string "hello, tape". This program will work with a file, and a floppy device, but not a tape device. can anyone give me some pointers? what do i have to do differently to write to tape? Thanks, --brad

Reminder: WLUG meeting July 17th (WEDNESDAY)

by Andy Stewart

HI everybody, This month's WLUG meeting will be held on Wednesday, July 17th in Kinnicutt Hall on the WPI campus at 7:00 PM. The topic will be "Wireless Networking" and I'm pretty sure we have a speaker. If you have a laptop with a wireless connection, bring it along. I'll bring my new Linksys access point (WAP11) and my laptop. Bring whatever you think will make this an interesting meeting! After the meeting, we'll make a trip to the Boynton Restaurant for pizza and beer. I hope to see you there!

interesting problem

by Wesley Allen

Shortly after I started using a wireless lan, I began having problems with connecting to my local ip addresses; I'm not sure what's causing it. Internet works FINE, and yet, a couple of minutes after I boot my machine I can't connect to anything in the 192.168 range! It doesn't matter the protocol, smb, http, etc. no connections at all. What's stranger is that my win4lin install, which uses vnet, has no problems at all. What in the world is going on here? Any thoughts? Wes

Lexmark z22 printing

by Bill Smith

Printing fun... Some of you might already know what I have to say, but I wanted to get this out for those that are in my boat... I am running a Gateway Solo 9100 laptop with Red Hat 7.3 installed. I mentioned a few months back (almost a year ago, now) that I had gotten my Lexmark z22 to print with Red Hat 7.1. One thing that I hate about upgrading RH versions is that it invariably forces me to re-learn things, since Red Hat can't seem to leave current configurations alone. 8\ ANYWAY, for a bunch of Stupid Reasons, I decided that I wanted to make use of the USB port on my z22 instead of the parallel port. Imagine, if you will, the fun I had in trying to get a printer that is barely supported by Linux to be recognized on the USB interface... I went to Lexmark's website and got the Linux drivers. Wouldn't you know it, though, but the drivers make no effort whatsoever to support the USB interface on the printer! After a bit of poking around, I realized that there was a KDE Control Panel! I use Window Maker by default and I was annoyed that control-panel was removed. I went through there and LO! the Lexmark z22 is there, right on the USB interface! 8) Granted, there are a couple snags. It looks like I can print multiple text-only documents with no problem, but if I print a Postscript file, then I have to turn the printer off then turn it on again. Compared to having no printer at all (or worse-yet, having to print from WinDOZE!), I see this as only a minor inconvenience. I'm thinking that this rig is using the foomatic configuration scripts, which may be unacceptable to some. I base this thought on the fact that the driver in use is actually for the Lexmark 3200 series, which (according to the .xml file) may print "a bit too rich"... <shrug> It looks okay for the black text that I'm printing with right now. I just wanted to share what I came across. Any corrections/suggestions are appreciated. (Yes, I went to http://www.linuxprinting.org ...)

Re: [Wlug] Konqueror enhanced browsing

by Brad Noyes

There are called kioslaves (intoduced in kde2.0), there are pretty neat. A complete list can be found in the kcontol center information->protocals. Some of these kioslaves do not make sense to call directly, for example pop3. the pop3 kioslave is used by kmail. kioslaves are available to all KDE applications to read from, and possibly write to. For example you can write a document in kword, and save it to a location using a kioslave. Just type 'ftp://somehost/path' in the 'save as' location. The kioslave for ftp (kio_ftp) will be called and do the file I/O. There are other kioslaves available that are not distributed with KDE, like fish, which is a kioslave that will allow you to brows a remote machine using ssh.

Hi all, I've noticed in Konqueror that one can type things like: info: ...in the URL field and Konqueror will display info pages. There are others, such as: smb: lan: ftp: man: http: camera: The aforementioned are not listed in the Konqueror enhanced browsing configuration window, and I would guess that they are Konqueror defaults.

A lot of newer distros now mount /dev/shm as tmpfs, and it's basically a resizable ramdisk that will grow, shrink, or even swap out to disk as needed.

Both of these are nice tools to have around. --bind has made it into the mount man page, but the tmpfs is not documented in the man pages anywhere I can think to look. Does anyone know of a reason that it should not be used? I'm thinking of using it for some locking files and pid stamps -- all stuff that should not persist across a reboot. TIA, Bill

Is this an issue? Well, that's the difference between a filter like SpamAssassin and a blacklist like the RBL. Personally, I use several blacklists for open-relays at the SMTP level, since it's unusual to have a false-positive from an open-relay test (depending on the test of course). For a company, I would use a filter (like SA) and just let it mark up likely spam. You can then leave it up to the users to decide what they want to do with it. (SA adds headers indicating how likely a message is to be spam (the score/number of hits), and what tests matched a given message.)
