Logs from wireless routers disclosing L2/MAC info?
Some of the popular wireless routers have an option to email access/security logs to an account on the Internet. When enabled, the logs contain the last 24 bits of the MAC address of the router's cable modem port, (the rest could be guessed since the brand name is included in the email,) and, the MAC address of the cable modem's router port. Was I potty trained wrong, or is this risky.

Anything is possible, but nothing is easy. How do you mean ? I did not install it yet but it sounds useful if cups could handle a serial fax like a printer :) Aldo i think the script can only send faxes and not handle incoming faxes like printing them or sending them to a mailbox directory. But i am sure you can add some magic faxing features to it :) 10$ its going to be a popular port and for people like you not that hart to add some fax incomming features :) With a little bit of luck you don't have to compile anything :) It does work well, (as per the sparse docs in the tar file.) You can use efax for incoming faxes, (or better, hylafax, if you can talk [EMAIL PROTECTED] into coming down and configuring it for you,) and the fax4CUPS does appear as a printer according to lpstat -a, and does send faxes, (saved as a postscript file out of openoffice.org, etc.) You will have to use cup's lpr -j option to tell it the fax printer what number to send the fax to, (so you will probably have to configure a printer in everyone's openoffice.org, etc.) The lpadmin command to install the cups/efax printer is: lpadmin -p efax -L machine -D fax -E -v efax:/dev/ttyXX -m efax.ppd Where efax.ppd is installed in probably /usr/share/cups/model/, and the efax script, (with the first 8 lines modified for your configuration,) installed in probably /usr/lib/cups/backend/. Note: if efax answer is running on /dev/ttyXX from /etc/inittab, it may be necessary to disable efax answer for the lpadmin command, but only to install the fax printer, (apparently, lpadmin doesn't like other things listening on its serial printer ports when it installs the printer.) If you use efax or hylafax for incoming, enable MIME e-mailing of the fax to a faxmaster, who distributes the file to the appropriate machine-its default for hylafax. For efax, configure /etc/efax.rc and /usr/bin/fax, (these are some script changes,) to send the fax attachment as a postscript file so they can be read with gv/ghostscript, (which probably came with your cups installation.) The efax/tiff file formats come out half size if a low resolution fax is received, which is corrected if postscript is used. Recommendation: YMMV, but hylafax is a bit difficult to configure, but is very robust once running; efax is probably preferable for non-industrial strength applications. FWIW ...

Re: Very slow printing with stock FreeBSD5.3 + CUPS + Gimp-Print + HPDeskJet612C
Anthony M. Agelastos writes: Hello all, My HP DeskJet 612C printer is printing unbearably slow (0.033 PPM). I have a stock installation (GENERIC KERNEL) of FreeBSD 5.3 straight off of the install CDs, and I have installed very little software thus far. I have mainly followed the installation instructions from http://www.csua.berkeley.edu/~ranga/notes/freebsd_cups.html It basically prints one line at a time, then pauses for a while, and makes some noises, and then repeats. The whole single test page took over 30 minutes to print. Does anyone have any insight/info that they can give me to solve this problem or point me in the right direction of solving it? I have Googled and done some searching and did not come up with anything. I checked the CUPS documentation and forums and did not see anything either. Maybe, make sure you installed the correct driver-there are two; a high resolution, (something like 3K dots per inch, and it will only do 3K dots per inch, which makes it very slow,) and a driver that uses the CUPS specific version of ghostscript, ESP ghostscript, (the other drivers require all of gimp-print to be installed.) The ESP ghostscript drivers end with a -ijs extension, and that's probably the one you want. Look at the ppd file you installed in probably /usr/share/cups/model/ for something like: *cupsFilter: application/vnd.cups-postscript 0 foomatic-rip and see if there is anything in the file ending with -ijs. John BTW, this solved the same thing on my Epson Photo Stylus 780.

Re: Blacklisting IPs

A practice one of my former co-workers liked was to pick a song and pull
letters out; take Fleetwood Mac: Don't Stop Thinking About Tomorrow.
You could get DSTAT, turn that into something else, like dSt4T.
Pretty short, but definitely not a dictionary word. You could even take
more letters from the next line Don't Stop, It'll Soon Be Here and get
dSt4TDs1SbH, or any number of derivations. If you forget the actual
password, your song is an excellent hint.
I think that comes from RFC1244, (Site Security Handbook,) which is a
pretty good security SOP for *_general_* 'Net users.
The stuff 1244 suggests is not perfect, by any means, but is a
relatively good compromise between security, usability, and
operational costs.
For example, to keep sysadmin phone calls on forgotten passwds to a
minimum, 1244 suggests the words in a user's favorite song, ('cause
folk's minds remember the words,) to seven letters-maybe with
capitalization. For example, if the Star Spangled Banner is the
'fav, then a passwd would be oH#saY#caN#.
If logins must be updated periodically, then the user's next passwd
would be, yoU#See, and so on.
Its certainly not perfect[1], but its cheap to administer, easy to
use, etc., and realatively hard to crack by algorithmic means-at least
without filling up the log files, giving the sysadm a heads up to
type something beginning with block ...
1244 has a lot of cute little security things like that.
John
[1] Yea, I've tried a passwd policy of denied vowel-consonant
relationships, (e.g., words.) Not only did I have a lot of phone calls
on forgotten passwds, I gained credentials as an English teacher.

Re: ssh protocol in 5.3
From 5.3 do ssh -1 [EMAIL PROTECTED] You can also set a protocol, 1 or 2, in the ssh configs, either globally in /etc/ssh ... or ~/.ssh/config. You can also use both, at the same time. ~/.ssh/known_hosts and ~/.ssh/authorized_keys can have both protocol 1 and 2 records in the same file; the identity files are different for 1 an 2, but have different file names in 1 and 2, so can coexist in ~/.ssh.
