uptime command on 5 different boxes I maintain.2:06am up 331 days, 20:38, 1 user, load average: 1.00, 1.00, 1.00 2:10am up 243 days, 6:06, 0 users, load average: 1.00, 1.00, 1.00 2:11am up 198 days, 5:43, 0 users, load average: 1.00, 1.00, 1.00The 198 day box is a router/firewall running on a 133Mhz Pentium, if this quit working, I'd have lots of people pissed at me. The 243 day box is a mail/web/dns server running on a PentiumPro at 200Mhz, and if that didn't work, I'd have probably even more people pissed at me. The 331 day box, is a redhat 5.0 system, running on an old 486 66Mhz Compaq, with a 120Mb hard drive, running samba, and playing music on my stereo through the built in sound card (over the network). These are real life systems that are running as I type this, not systems that belong to someone else, or some great uptime from a year ago. I just installed a Linux router, that boots off a floppy disk, then runs the entire system from a ramdisk, lets see you do that with windows. Linux/Unix is more robust, stable, secure, and mature than windows will ever be. (Linux/Unix has over 30 years of heratige, that is not "old", this is "mature").
md5sum. The .sfv file
can be generated with several program under windows and linux.
Both .md5 and .sfv files are checksums, used to make sure the files
you've downloaded are not corrupt. Md5sum is the Linux/Unix standard
program for generating/checking md5 checksums. Md5sum is the perfered
program for "unix people", where "windows people" perfer the .sfv format.
bchunk). Sometimes
you'll run into a bin/cue that won't convert into an .iso properly (like the 2nd CD for Kylix,
and I have a patch to fix that. If you run into a bin/cue that is 2048 bytes per sector,
then you can treat that .bin just like an .iso.
dd if=/dev/zero of=/dev/hda bs=512 and replace hda with sda if you're running SCSI.cp /dev/cdrom filename.iso (you may get an error at the end of the CD this way, but it is not a problem.)dd if=/dev/cdrom of=filemname.iso bs=2k
mkisofs -r -o filemane.iso -V "CD Label" to_burn/ (if you're making a CD
for a windows computer you'll want to replace the "-r" with a "-J")mount -o loop filename.iso /mnt/cdromlosetup program, read
the man page for more details.
