 Ok, for those of you who saw my recent message about the illegal
 instruction ... I think I now know why that doesn't work. I think it
 is that the latest sse2-3.4.2 virtual machine does not support my
 processor (AMD Athlon 64 3000). I don't know why, since this cpu does
 support sse2, but perhaps one sse3 instruction is used somewhere and
 the Athlon does not support sse3, and thus it crashes.

No, the problem is not SSE3, but certain advanced instructions used in
MPIR. This will be fixed in Sage 4.0.

 Anyway I tried running it on a newer laptop on my network, and it did
 indeed start a sage server. When I start firefox on this computer and
 go to the suggested address (192.168.175.128) the sage server starts
 up and I can execute sage commands. (Yay!!)

 I'm wondering though, can I run sage from another computer on my
 network? After starting the sage server on the laptop as usual, I
 tried typing in 192.168.175.128 in the browser on my desktop computer,
 but it just reports that it can't connect. How do I get this to work?

This is the VMWare image, right?

Networking and VMWare are a bit weird. I'm not using the player so  
things might be a bit different, but I have options in VMWare to set  
the networking up three ways.

* Host-only : The network can only send/receive to the host OS. No  
other machine can communicate with the guest OS.
* Bridged : The guest OS is effectively plugged straight into the  
network. It'll get an address from the main network. Other machines  
should be able to see it.
* NAT : The guest OS looks like it's behind a NAT-ing router.  
Effectively it always gets the same address whatever network the host  
OS is on. Other machines probably can't see it, but it can see the  
real network.

I expect you want Bridged, but probably are set-up for something else.

 Do I have to make an entry in the Firewall  Virtual servers section
 of my router or something like that?

Firewall on your laptop, or firewall on a router on the network?
If it's on the router, then no, that's only for access outside your  
network.

If we're talking about on the laptop, then I'm not sure. I'd expect  
VMWare (in bridged mode) to bypass the firewall as it's receiving  
packets on a different address to the one the firewall is monitoring,  
but I don't know.

As I said VMWare and networking is a little odd.

Yep.

 * Bridged
 * NAT

Yes, NAT was selected. I tried changing it to Bridged, but then the
sage
server didn't work even on the machine running the sever. Of course
I didn't know if I was supposed to go to the same IP address as
before,
or something different.
