Package: python-x2go Severity: important Since python-gevent 1.0 gevent fails to detect DNS changes (e.g. when connecting to a VPN server). From http://gevent.org/whatsnew_1_0.html : """ New dns resolver Two new DNS resolvers: threadpool-based one (enabled by default) and c-ares based one. That threadpool-based resolver was added mostly for Windows and Mac OS X platforms where c-ares might behave differently w.r.t system configuration. On Linux, however, the c-ares based resolver is probably a better choice. To enable c-ares resolver set GEVENT_RESOLVER=ares environment variable. This fixes some major issues with DNS on 0.13.x, namely: Issue #2: DNS resolver no longer breaks after fork(). You still need to call gevent.fork() (os.fork is monkey patched with it if monkey.patch_all() was called). DNS resolver no longer ignores /etc/resolv.conf and /etc/hosts. The following functions were added to socket module: gethostbyname_ex getnameinfo gethostbyaddr getfqdn It is possible to implement your own DNS resolver and make gevent use it. The GEVENT_RESOLVER variable can point to alternative implementation using the format: package.module.class. The default is gevent.resolver_thread.Resolver. The alternative “ares” resolver is an alias for gevent.resolver_ares.Resolver. """ Thus: we need to enforce setting of env variable GEVENT_RESOLVER=ares in Python X2Go.
