freshclam: create_curl_handle: Unable to bind DNS resolves to xxx.xxx.xxx.xxx. Option requires that libcurl was built with c-ares.
by babydr from LinuxQuestions.org on (#5GBWH)
Having just compiled and installed on a MultiInterface server clamav-0.103.2 following the contents (if NOT using the script) of SlackBuilds.org for clamav .
The freshclam.conf.8 manpage says (to me) insert your primary exterior interface ip in the config entry , "LocalIPAddress" , So I did .
When running freshclam (see below(*1)) , curl reports the message saying that libcurl needs c-ares (ie: libc-ares) be complied in , in order to use the "LocalIPAddress" functionality .
Fyi , Leaving "LocalIPAddress" empty allows freshclam to run just fine . As my system is multiInterfaced tho Not multirouted at the moment but will be , Thus my concern .
Tho for those running on true MultiRouted servers are going have a problem when they HAVE to use the "LocalIPAddress" .
How & Who should be contacted to have this library be compiled into curl ?
(*2) Below MAY show that curl is not compiled with libc-ares .
Tho ...
