Package: dnsmasq
Version: 2.55-2
Severity: normal
I am using resolvconf and dnsmasq to handle internal DNS servers for
our VPN. When openconnect creates the tun0 interface, it adds the
internal nameservers using resolvconf. resolvconf modifies dnsmasq's
configuration file, and dnsmasq rereads it. But my IRC client fails
to reconnect to the internal server at this point, because the
negative lookup has been cached - the IRC server's hostname is only
valid inside the VPN.
I don't see any option to make dnsmasq clear its cache when the VPN
comes up other than restarting dnsmasq entirely. It'd be nice if I
could make this happen automatically when dnsmasq rereads the
resolv.conf file.
