[Simh] EXT : Network Problem

Hi Priya,
Dave may be right, BUT there still is something strange about your environment.
Dave Johnson had suggested that you need to run as root. I don't think that your problem is due to the running as root issue since if that were the case "SHOW ETHERNET" usually wouldn't have mentioned eth0.
The various attempts you made to install a libpcap development environment have left your system in a situation I'm explicitly removing support for going forward.
The key information which is most likely the problem is:
using libpcap: /usr/local/lib/libpcap.a /usr/local/include/pcap.h

It seems that the libpcap components you've built with were NOT directly provided by RedHat as part of their Linux distribution or it wouldn't have installed in /usr/local ....
Some folks have mangled the working components of libpcap on their Linux systems by attempting to install various versions of non-OS-vendor supplied libpcap components. This mangling is why support for doing this that way has been officially deprecated. Your case has inspired me to take the time to completely remove this support for host platforms which have known good vendor supplied libpcap components (i.e. Linux).
You should uninstall the package you found which dropped the libpcap pieces in /usr/local.
I'm not a paid RedHat user and therefore don't have access to their customer portal to access their knowledgebase, however since you appear to be, you may want to look at the solution provided by:
https://access.redhat.com/site/solutions/57913
Can you explicitly describe EXACTY what version of RedHat Linux you're working with and get back to me directly. I'll dig up libpcap directions for that platform and add it to the simh 0readme-ethernet.txt.
Please get back to me.
Thanks.

Rerun @SYS$MANAGER:TCPIP$CONFIG to fix your TCPIP hardware interface definitions.
The error is telling you that it can't find the VAX hardware device (no such device SE0) to attach (on the 4th line).
The MicroVAX 3900 in the SIMH VAX does not have an SE0 interface, it has a QNA interface.
I think SE0 was the built-in MicroVAX/VAXstation 3100 interface.
Was this system disk originally used by a different VAX emulator (like Charon/SRI) or a different model of real VAX?

Hi,
I am trying boot a vax disk on SIMH and it keeps getting hung while starting network like TCP/IP.
I have the required lipcap packages. My host is RedHat VM. The simulator was built with network support.
