The rsh solution worked for me actually. I used this:
dd if=/dev/rrz1c conv=noerror,sync | rsh ult1 dd of=/usr/rz1.dd Where “ult1” was the remote node Thanks Rob From: Huw Davies [mailto:[email protected]] Sent: 23 October 2017 09:32 To: [email protected]; Rob Jarratt <[email protected]>; General Discussion: On-Topic and Off-Topic Posts <[email protected]> Subject: Re: Cloning A Hard Disk Over The Network Using Ultrix On 21 Oct 2017, at 21:40, Rob Jarratt via cctalk <[email protected] <mailto:[email protected]> > wrote: I have a couple of hard disks I want to make dd copies of. I have Ultrix running on my DECstation 5000/240 with the disk I want to clone attached to it. The trouble is that I don't have enough disk space on the machine to clone the disk and then grab the image using FTP. I have been trying to find a way to pipe the dd output over the network to a SIMH Ultrix machine that has plenty of disk space. I tried piping dd into rcp, but rcp doesn't seem to take input from standard input. I have looked at cpio, but that too appears not to accept input from standard input. Unix is not my strong point. Are there any other ways I could pipe the dd output across the network to a machine that has enough disk space? netcat (nc) is the usual tool to do this on Unix type systems. Whether it’s available for Ultrix I don’t know but it may ‘just compile’. If not, it’s not hard to write two simple programs to read from stdin and output to a TCP/IP socket on another host and the second to read from the socket and output to stdout. If I had to write the programs I’d either google for an example to copy or have a read of Stevens “TCP/IP illustrated” book series - the only risk of reading them (there are 3 volumes) is that you can spend 6 months just learning and not doing :-)' Huw Davies | e-mail: [email protected] <mailto:[email protected]> Melbourne | "If soccer was meant to be played in the Australia | air, the sky would be painted green"
