"scons run" fails on Ubuntu with "asdev_open device <lin/socket/0> failed"

[CM0804]

I am running Ubuntu14.04 on virtual box (Hosted on Windows).
Have set following environment variables:
export BOARD=posix
export RELEASE=ascore

Able to build but while trying to run, it gives below error:

:~/cm_workspace/as/as$ scons run
scons: Reading SConscript files ...
!!!LWIP run on pthreads!!!
start application BUILD @ Apr 23 2021 22:08:49
cpu is little endian
XCP MTA memory address 0x977700
mount asblk1 on / okay
mount asblk0 on /dos okay
Connection refused
WARNING :connect function failed with error: 111
asdev_open device <lin/socket/0> failed!
STDERR :assert error on condition(0) at line 555 of asdev_open com/as.tool/lua/device/lasdevlib.c

Tried to understand the flow and it seems,
Lin_InitChannel -> asdev_open fails with "lin/socket/0".

Will you please give any pointers what could be wrong / how can I resolve?
Thank you in advance.

I could understand the problem, on Ubuntu Lin socket server has to be started manually. I think on Windows its automatically taken care.
I will close this issue with this.

Further problems:
on the cluster display, speed and rpm gauge niddle are steady

Server side logs:

Client side error:

I will debug this further or raise separate issue.

Amazing work @parai. Thanks a lot.
