The service-node provides a FTP service to support file transfers with the host using FTP clients on a target machine.
Assuming a service-node has been created, and that it
is named default_service_node0, the FTP-service will be named
default_service_node0.ftp.
The service node must be configured with an IP address and connected to a link
before the FTP service can be enabled and configured.
The FTP root directory, the location
on the host system for transferred files, can be set by the
set-ftp-directory command. The default root directory is
the current directory for the Simics session, usually your project
directory.
On a target that runs Clear Linux there is usually a curl command for transferring data using various protocols, it can put a file to the server and retrieve a file from the server.
Here is an example on using the FTP service on a target running Firststeps with a network. Start Simics and run the following commands:
simics> run-command-file "targets/qsp-x86/firststeps.simics" simics> default_service_node0.set-ftp-directory dir = "/tmp/"
A Firststeps target was created. The target
machine's IP address is 10.10.0.1 and it contains
a default_service_node0 with the FTP service. The root
directory was set to the /tmp/ directory on the
host file system.
Continue the simulation until a prompt is reached.
simics> c
When prompt has been reached, the curl command can be run in the text console.
~ # curl -T /etc/hostname ftp://10.10.0.1/targetfile.txt
The contents of the target file /etc/hostname has now
been sent to the host file targetfile.txt in the path
set from the set-ftp-directory command. In similar way:
~ # curl ftp://10.10.0.1/targetfile.txt -o hostfile.txt
will retrieve a file, targetfile.txt, from the host and
save it as hostfile.txt on the target.
Using other kind of distributions of Linux than Clear Linux there will most likely exist a ftp command in the shell for running a ftp client. An example on how to put a file to the host:
#> ftp 10.10.0.1 Connected to 10.10.0.1. 220 Welcome to the Simics FTP server Name (10.10.0.1:simics): <enter> 230 User logged in ftp> put /proc/cpuinfo targetfile.txt local: /proc/cpuinfo remote: targetfile.txt 200 OK 150 transfer about to start 226 file transfer done 6520 bytes sent in 0.00 secs (12734.4 kB/s)
If running Microsoft Windows as target then Windows Internet Explorer can be used as client to connect to the FTP service by entering ftp://10.10.0.1 as address. This will allow transfer from host to target. To be able to transfer files back to the host you will need to select Page → Open FTP Site in Windows Explorer.
