Hi, When I run the Juniper Network Connect client (ncsvc) it terminates every time the DHCP license is renewed. The log files of ncsvc are unfortunately rather cryptic, but it appears as if the DHCP renewal leads to a change in the routing table which triggers a "rmon.error" in ncsvc which then tears down the VPN tunnel. Using timestamps the following two events correlate:
20150603133456.514649 ncsvc[p6870.t6870] rmon.error Route to destination 192.168.1.1 is missing mask 255.255.255.255 with gw 0.0.0.0, metric 1, if_id 0, disconnecting (routemon.cpp:628) which coincides with the following journal entries: Jun 03 13:34:55.454967 host NetworkManager[1805]: address 192.168.1.16 Jun 03 13:34:55.454985 host NetworkManager[1805]: plen 24 Jun 03 13:34:55.454990 host NetworkManager[1805]: expires in 300 seconds Jun 03 13:34:55.455026 host NetworkManager[1805]: gateway 192.168.1.1 Jun 03 13:34:55.455035 host NetworkManager[1805]: nameserver '192.168.1.1' Jun 03 13:34:55.455210 host NetworkManager[1805]: (wlp6s0): DHCPv4 state changed bound -> bound Jun 03 13:34:55.456679 host dbus[1799]: [system] Activating via systemd: service name='org.freedesktop.nm_dispatcher' unit='dbus-org.freedesktop.nm-dispatcher.service' Jun 03 13:34:55.461372 host dbus[1799]: [system] Successfully activated service 'org.freedesktop.nm_dispatcher' Jun 03 13:34:55.462021 host nm-dispatcher[8295]: Dispatching action 'dhcp4-change' for wlp6s0 Jun 03 13:34:56.514958 host systemd-networkd[1803]: tun0 : lost carrier Besides the ncsvc error listed above I sometimes also see this one: 20150603132151.174661 ncsvc[p6870.t6870] rmon.error Unauthorized new route to 192.168.1.0/0.0.0.0 has been added (conflicts with our route to 0.0.0.0), disconnecting (routemon.cpp:598) Both seem to indicate that the routing table is changed on DHCP renewal. Is there a way to prevent networkmanager from doing this? Or is this problem caused by something else possibly? systemd-218 networkmanager-1.0.2 Thanks for any suggestions, nick
