Re: OT Spamming question
What amazes me is that, even though I see some attemps at relaying on my server, all of them are failing (I am pretty sure - I only see the transmit denials and no successes in the transfer logs). Still, some of the same sources keep trying over and over. Don't they detect when it has not worked? I need a policy for complaining to their ISPs. To date we have just ignored them. BTW, exim is pretty good at dealing with the relay problem. I prefer it as it is easier to configure than sendmail, yet it recognizes the same command line options. It can be a drop-in replacement for sendmail. Just a happy user here. On Fri, 3 May 2002 05:50:24 -0500 David A.

Basically, the spammer hijacks the mail server or just sends large amount of mail to the business everyday. Is this a special problem just for silly people? I have a mail server going and, except for my early days on linux, have never been exploited in this way, even thought I am on line 24/7. So, is this just a problem of people who don't know what they are doing? The most popular mail transport agent (MTA, also known as a mail server), is sendmail. Until sendmail version 8.9.x, the default configuration was to relay mail, no questions asked. While today we are at sendmail 8.12.3 (sendmail 8.9.x was released years ago), many old installations have never been upgraded and still have this problem (among others, like security holes big enough to fly 747's through, but that's another story). Many other MTAs suffered the same problems. Most have been patched. But all can be easily reconfigured to relay mail from anyone who cares to use it, with no brakes on the system (max # of recipients, max # of messages you can send at one time, etc.). Combine the above with know exploders (a mail address that is nothing more than an alias for thousands of other mail addresses), and the problem is tremendous. Current estimates place the # of spam messages on the Internet at any given time at 20% of the e-mail messages on the Internet. SPAM has been known to bring even BIG mail servers down.

Re: RH7.2 CD-Roms Enable scsi emulation.
Umm I don't know if this will help but I pass a kernel parameter when I boot for my CDRW/DVD A Ricoh 9200A... so in grub I put hdX=ide-scsi where X is the letter of your CD/CDRW To tell the kernel to treat it like a scsi device I think it's called scsi emulation. Here is a sample from my /etc/grub.conf title Red Hat Linux (PreEmpt) root (hd0,2) kernel /boot/vmlinuz-2.4.18-2002-04-25preempt ro root=/dev/hda3 hdc=ide-scsi initrd /boot/initrd-2.4.18-2002-04-25.img # the above lines from kernel to ide-scsi is on one line if you have another cdrom / cdrw put hdc=ide-scsi hdd=ide-scsi change the lettering to suit your install. if you have to do this in lilo put an append=hdc=ide-scsi hdd=ide-scsi in the global configuration area (i.e. up the top of the file not in the seperate image sections) I did the following command as root. ln -sf /dev/scd0 /dev/cdrom If you have a cdrom and a cdrw then do both these... ln -sf /dev/scd0 /dev/cdrom ln -sf /dev/scd1 /dev/cdrw and your fstab should have these entries so you can mount both as CD's /dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0 /dev/cdrw /mnt/cdrw iso9660 noauto,owner,kudzu,ro 0 0 any of your burning sotware should refer to the /dev/scd1 device or whatever your cdrw is... number it is if you do it correctly you will get the following when you do a dmesg | grep hd. Kernel command line: ro root=/dev/hda3 hdc=ide-scsi ide_setup: hdc=ide-scsi telling you the kernel has read the parameter and understands that you want to treat your IDE CD's like scsi...

KDE3 compile partial failure
I tried installing KDE3 from source using checkinstall. After much ado with libraries missing or outdated, much fussing with qt3 and a lot of trial and error, things seemed to be going smoothly, until . . . kdebase crapped out with: FontEngine.cpp:55: freetype/ftsnames.h: no such file or directory. ftsnames.h is in /usr/X11R6/include/freetype2/freetype/ftsnames.h . I added that to PATH and tried again, but no go. When qt3 compile stopped by not finding qname, I added its location to PATH, and qt3 went smoothly. But here, nothing. kdeartwork failed with: make [3]: ***No rule to make target `/opt/kde3/lib/kwinla' needed by `kwin-openlook.la.closure' Stop. kdeaddons failed with missing files, all kate/ : plugin.h, application.h, docmanager.h,mainwindow.h and viewmanager.h On WS 3.1.
