This section describes how to import hostlists from a text file.

To import hostlists from a text file

1. Create a plain text file containing the hostlist policies and IP addresses to import. Every line of the file will add an IP address or network to a policy. Use the following format:

   name_of_the_policy;match

   or

   ignore;IP address

   For example, a policy that ignores the 192.168.5.5 IP address and another one that matches on the 10.70.0.0/24 subnet, use:

   policy1;ignore;192.168.5.5
   policy2;match;10.70.0.0/24

   To add multiple addresses or subnets to the same policy, list every address or subnet in a separate line, for example:

   policy1;ignore;192.168.7.5
   policy1;ignore;192.168.5.5
   policy1;match;10.70.0.0/24

2. Navigate to Policies > Hostlists > Import from file > Browse and select the text file containing the hostlist policies to import.

   Figure 108: Policies > Hostlists — Importing hostlists

   

3. If you are updating existing policies and want to add new addresses to them, select Append.

   If you are updating existing policies and want to replace the existing addresses with the ones in the text file, select Replace.

4. Click Upload, then .

   NOTE: If you modify a hostlist, you only need to restart syslog-ng if a host, which is already connected, needs to be ignored with a hostlist. Navigate to Basic Settings > System > Service control > Syslog traffic, indexing & search: and select Restart syslog-ng for the changes to take effect.
