# 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. |
