Ubuntu Server 18.04 no IPV4 after resume












1














I fail to get ipv4 working on an ubuntu server 18.04 after it was suspended and resumed. The only way I get ipv4 running again is reboot. The system is installed as a guest in a vmware virtual machine.



before resume:



ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
inet 192.168.0.96 netmask 255.255.255.0 broadcast 192.168.0.255
inet6 fe80::20c:29ff:fe1c:7d22 prefixlen 64 scopeid 0x20<link>

RX packets 4554 bytes 1079672 (1.0 MB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 917 bytes 77010 (77.0 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0


lshw -C network tells me amongst other things:



driver=e1000


after resume:



ens33: flags=4098<BROADCAST,MULTICAST>  mtu 1500
ether 00:0c:29:1c:7d:22 txqueuelen 1000 (Ethernet)

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 919 bytes 77160 (77.1 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0


after ifconfig ens33 up:



ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
inet6 fe80::20c:29ff:fe1c:7d22 prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:1c:7d:22 txqueuelen 1000 (Ethernet)

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 924 bytes 77606 (77.6 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0


I see no IP v4 address. After googling I tried



# modprobe -r e1000
# modprobe -i e1000


but it does not change anything in the output of ifconfig. The only thing that seems to help is shutdown -r...



Any advice what else I could try?
