# 01/xx/2003 Ron Fox.. Remove preforking. This makes the general daemon |
### |
# logic simpler (and there were problems maintaining the preforked |
|
# population). Since the time averaged connection rate is close to zero |
|
# because lonc's purpose is to maintain near continuous connnections, |
|
# preforking is not really needed. |
|
# 08/xx/2003 Ron Fox: Add management requests. Management requests |
|
# will be validated via a call to ValidateManager. At present, this |
|
# is done by simple host verification. In the future we can modify |
|
# this function to do a certificate check. |
|
# Management functions supported include: |
|
# - pushing /home/httpd/lonTabs/hosts.tab |
|
# - pushing /home/httpd/lonTabs/domain.tab |
|
# 09/08/2003 Ron Fox: Told lond to take care of change logging so we |
|
# don't have to remember it: |
|
# |
|
|
# based on "Perl Cookbook" ISBN 1-56592-243-3 |

=item pushtable |
|
|
|
Pushes a file in /home/httpd/lonTab directory. Currently limited to: |
|
hosts.tab and domain.tab. The old file is copied to *.tab.backup but |
|
must be restored manually in case of a problem with the new table file. |
|
pushtable requires that the request be encrypted and validated via |
|
ValidateManager. The form of the command is: |
|
enc:pushtable tablename <tablecontents> \n |
|
where pushtable, tablename and <tablecontents> will be encrypted, but \n is a |
|
cleartext newline. |
