[Simh] Ethernet connection problems

[Mark Pizzolato - Info Comm]

Hi Priya,

Hmmm...

There was a fix checked into the github repository about 21 hours ago which fixed an Ethernet issue and which the version you've built does not contain.

You will definitely need the latest code,

However, that doesn't seem to be the issue you are encountering.  It seems you've built a simulator without support for libpcap.  The output produced when you performed 'make vax' would be more informative regarding this.

It probably suggests that you need to install the libpcap-dev package for your simulator to have Ethernet support...

If after considering this, you still have a problem, please open an issue at https://github.com/simh/simh/issues.

Hi,

I'm installing SIMH on RedHat VM. I seem to have Ethernet connection problems.

; Choose one of the following lines. SET CPU CONHALT returns control to the
; VAX console monitor on a halt event (where behavior will be further
; determined by whether auto-boot is set--see above. SET CPU SIMHALT will
; cause the simulator to get control instead.
set cpu conhalt
;set cpu simhalt
;
; Now start the emulator
boot cpu
;
;Exit the simulator
;exit

The steps I followed for installing of the emulator are:
$ wget   https://github.com/simh/simh/archive/master.zip
$ unzip simh-master.zip
$ cd simh-master
 $ make vax
