to copy files unix to unix automaticlly you will need to do the following
1: setup public key exchange for the user you will run the cron script as
1a: type ~>/usr/local/bin/ssh-keygen2 -P
1b: you should get
~>/usr/local/bin/ssh-keygen2 -P
Generating 1024-bit dsa key pair
8 .oOoo.oOo.oO
Key generated.
1024-bit dsa, alx@HELIOS, Fri Oct 27 2000 16:02:44 -0700
Key is stored with NULL passphrase.
Private key saved to /home/alx/.ssh2/id_dsa_1024_a
Public key saved to /home/alx/.ssh2/id_dsa_1024_a.pub
1c: type /usr/local/bin/ssh2 -l user server.ip.address
1d: type cd ~/.ssh2
1e: type ~>echo Key id_dsa_1024_a.pub >authorization
1f: type exit
1g: type ~>echo IdKey id_dsa_1024_a >identification
1h: type /usr/local/bin/scp2 /home/alx/.ssh2/id_dsa_1024_a.pub
[EMAIL PROTECTED]:/home/alx/.ssh2/id_dsa_1024_a.pub
2: write script to copy your files (use my test script below as an example)
here is the contents of my test cron script : /test/crontest
/usr/local/bin/scp2 -B /test/files2* [EMAIL PROTECTED]:/test/crontest/
2>/var/log/testerror.log
contents of /etc/crontab:
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
MAILTO=root
HOME=/root/
# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
23 * * * * alx /test/cron
/usr/local/bin/scp2 -B /test/files2* [EMAIL PROTECTED]:/test/crontest/
2>/var/log/testerror.log
/usr/local/bin/scp2 = location of scp2 command
-B = option to start scp2 in Batch Mode
/test/files2* = source files (copy all files starting with files2)
for my tests there are 5 files about 1 MB each
alx = user cron will login to server as
@ = tells cron the following is the server
192.168.13.127 = ssh server (ether IP address or FQDN)
: = tell's cron the following is the file
/test/crontest/ = location on server files will be placed
2> = redirect error msg's to...
/var/log/testerror.log = location and file name of where all error msg's
