Companies Fight Endless War Against Computer Attacksby STEVE LOHR, New York TimesThe recent computer attacks on the mighty Google left every corporate network in the world looking a little less safe.Google's confrontation with China - over government censorship in general and specific attacks on its systems - is an exceptional case, of course, extending to [...]
I have number in file which contains date and serial number:
2013101000.
The last two digits are serial number (00). So maximum of serial number is 100.
After reaching 100 it becomes 00 with incrementing 10 which is day with max 31.
after reaching 31 it becomes 00 and increments 10... (31 Replies)

Hi,
I'd like to know how can I figure out my disk space area on AIX machine, for example to the situation of ( df -g ) which I have in my system :
the area used by (/opt/oracle) file system is (98%) now.
the free area on (/opt/oracle) is (0.75) now.
the total size in Gigabyte... (1 Reply)

This is a slightly lobotomized kermit. The help command, thescript facility, and the automatic dial support have been re-
moved. The ? and ESC commands still work, so there is still rea-
sonable built-in help. The only V7 kermit feature that does not
work is the ability to see whether there are input characters
waiting. This means that you will not be able to ask for statusduring a file transfer (though this is not critical, because ker-mit prints a dot every so often and other special characterswhenever there is an error or timeout). Start kermit, and thentype the following to open a 2400 baud session, for example:
(It is more convenient if you put these commands in .kermrc in
your home directory, so that they get done automatically wheneveryou run kermit.) This will connect you to the modem or whateveron the serial port. Now log into the other system. When you
want to transfer files, run kermit on the other system. To it,type This puts its kermit into a sort of slave mode where it ex-pects commands from the kermit running on your MINIX system. Nowcome back to the command level on MINIX kermit, by typing the es-cape character followed by c. (Kermit will tell you the currentescape character when you do the connect command.) At this pointyou can issue various commands. Your kermit will coordinatethings with kermit on the other machine so that you only have to
type commands at one end. Common commands areFilenames can include wildcards. By default, kermit works in a
system-independent, text mode. (In effect it assumes that thewhole world is MS-DOS and converts end of line and file names ac-cordingly.) To send binary files, you will want to type on bothends before starting any transfers. This disables CR LF to new-line conversion. If both of your systems are some flavor of
UNIX, you might as well put this in .kermrc on both ends and runin binary mode all the time. Also, if both systems are UNIX it
is recommended that you use on both ends. This causes it to keepfile names unchanged, rather than mapping to legal MS-DOS names.Here is a typical .kermrc for use onOn the other end of the line, for example, the host at your localcomputer center to which you want to transfer files, a typicalprofile might be:
Kermit has many other options and features. For a pleasant andhighly readable description of it, see the following book:

Over 400 versions of kermit are available, so it is likely thereis one for any computer your system might want to talk to. Co-lumbia University also publishes a newsletter about kermit thatcan be requested from the above address.
