Stress Test: ftpstress

TEST NAME

ftpstress - compare for data corruption

SYNOPSIS

sh ftpstress.sh remote_machine

DESCRIPTION

The ftpstress command sends files of different sizes from a local machine to a remote machine, back to the local machine, and compares for data corruption.

OPERANDS

remote_machine

Either the host name or the IP address of the machine to which files and directories are copied. If a host name is given, it must appear in /etc/hosts along with the remote machine's IP address.

USAGE VARIABLES

RUNTIME

Specifies, in seconds, the duration of the test.

local_ftpdir

Specifies the local directory to use for creating and copying files.

remote_ftpdir

Specifies the remote directory to use for creating and copying files.

SETUP

You need two machines connected by a network, either back-to-back, or through a hub or switch.

Before the tests can run, ensure that the local machine can make anonymous ftp transfers to the remote machine. This is described in detail in the in.ftpd(1M) man page. Under HCTS, this is set up by the setup_anon_ftp.sh script at install time.

OUTPUT

The test produces output that shows the progress of the test.

DURATION

24 hours

POSSIBLE CONCURRENT TESTS

This test can run concurrently with cl3se3, lsalr, mpflip, scp, and spray.

CAVEATS

If several instances of ftpstress are running concurrently, ensure that the test directories are different for each instance.

This test requires at least 1.2 Gbytes on the local machine and 600 Mbytes on the remote host.

EXAMPLES

# local_ftpdir=/export/home/tmp
# remote_ftpdir=incoming/
