On your Ethernet speed test ... how was that measured? (Is that a raw TCP/IP sockets performance number reported by the mTCP speed test program or is that an FTP number? If it is FTP is that reading or writing?)

I don't think the floppy disks are an issue. All of the code that you would need would fit on a 160KB diskette. You just need to be able to boot DOS, load a packet driver, possibly run DHCP, and then run the file transfer program. The Xircom PE3-10BT connects to almost any parallel port and to …

I have a version of the mTCP Netcat program that will basically let you stream the contents of a hard drive from a vintage machine to another machine on the network. It's basically the same thing that Ghost would do over a network - imaging the entire drive sector by sector. With something like a …

i have noticed on mine, mtcp ftp to my server, when i pull down a file, the bigger it is, ie: > 1 or 2mb, there is a huge huge chance of the transfer hanging and not completing, which is strange. sometimes I can pull down 50mb zips, other times anything over a couple of mb hangs A lot of servers …

I prefer to look at things like mTCP as more of a throwback to the Unix style of networking - classic Telnet, FTP, and utilities. Early networking for PCs was centered around file and printer sharing. It assumes that all of the machines are the same; you get to reach into remote filesystems directly …

Any particular reason why your house has multiple subnets? If there are multiple routers involved there are some solutions. One is to add a route that will let one subnet send packets to the other subnet. (By default 192.168.x.x addresses are private and non-routable.) The other is to get the …

Wait till you have to network DOS... Without cheating and using mTCP. So how is mTCP cheating? :evil: It is not MS style drive sharing but we already have a solution for that.

I agree though DOS would be a better match for an old PC, but then getting TCP/IP working to transfer files can often be a pain, so I wouldn't mind being able to boot Linux so I can use that to maintain the DOS partition! That and having something that properly uses the 286's protected mode would …
