Wireless LANs

by Andy Stewart

HI everybody, Now that I have a laptop, I'm interested in a Wireless LAN for it. I'm wondering if this is a topic of general interest that somebody might like to present at our next meeting. Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

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. I doubt that locking files are going to take up much space that you'd need back for memory, but on the other hand you probably don't need extra fast access to them either. ;-) Brian J.

tmpfs

by Bill Mills-Curran

When researching the Reiserfs a while back, I discovered the tmpfs file system and the --bind option to mount. 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.) Anything else that makes it through to delivery goes through SpamAssassin. Spams gets sorted into a seperate mail folder, and I then go through it and report the spammers, etc. There's some information about what I do for general filtering at: http://www.kluge.net/mailfiltering/ -- Randomly Generated Tagline: "And that's the success of Windows-it's mediocre, but it's easy." - Linus Torvalds

What's the file format of smbprn.000004.mITl7Y? Is it compatible with what the backend/parallel port/printer is expecting? i.e., if it is postscript, does the printer support postscript? If it is HPGL, does the printer support that?
