[PATCH] strip commas from dns search paths

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello there,

A juniper / pulse secure VPN that I connect to gives back multiple DNS 
search paths.  Using the openconnect 7.06 release, they end up in 
/etc/resolv.conf comma separated, which makes resolution by nonfully 
qualified name not work.

here's a quick patch i put together to fix for my use case:
