Hello, I have run into a very weird behaviour. The TCPIP communication works well both in and outbound. Ping, telnet, pop3 all works. BUT when I try to use FTP after the get or put command the whole SIMH dies. It also dies with during wget request.
Has anybody seen something like this? Is it something that I do wrong? Is the hardware too modern for SIMH (gigabit Ethernet NIC or x86_64 architecture)? It is obviously a SIMH issue because both Ultrix and VMS have the same behaviour. I guess the data transfer rate is much higher than expected and it might cause an overflow somewhere. -------------------------------------------------------- I run VAX simulator from simhv38-1 on an Linux virtual 2.6.37.6-0.7-desktop #1 SMP PREEMPT 2011-07-21 02:17:24 +0200 x86_64 x86_64 x86_64 GNU/Linux I run Ultrix 4.5 and VMS 7.3 on a very similar config: Here is Ultrix virtual:~/SIMH # cat ultrix/bin/vax.ini ; ; Load CPU microcode load -r /root/SIMH/ultrix/data/ka655x.bin ; ; Attach non-volatile RAM to a file attach nvr /root/SIMH/ultrix/data/nvram.bin ; ; This virtual machine has 256M memory set cpu 256m ; ; Define disk drive types.
