# 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 |

|
| |
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. |
