Setup guide

Using sw_ping to Test Network Performance

Use the sw_ping command to test network performance. For more significant results, run the test 100

times.:

1 Start sw_ping: /usr/discreet/sw/sw_ping -framestore <framestore_name> -r -w -size

Description:Option:

Is the name of the framestore to ping.-framestore <framestore_name>

Reads a buffer from the remote framestore.-r

Writes a buffer to the remote framestore (non-destructive).-w

Reads/writes a buffer of packetsize bytes.-size <packetsize>

Executes this test n times.-loop <n>

The following is an example for an NTSC (720 x 486 x 3) frame format, sent 100 times in read and

write mode to framestore my_framestore:

/usr/discreet/sw/sw_ping -framestore my_framestore -read -write -size 1049760 -l 100

Verifying Remote Clip Library Access and Permissions

Verify that the local host has write permissions to the clip library directory of the remote host:

1 Try to access the clip library directory of the remote host. Type: cd /hosts/

<remote_machine>/usr/discreet/clip

2 If an error message appears on the client machine, check to see that the required network daemons

are on. If you have access to /hosts/<remote_machine >/usr/discreet/clip, check you have root

privileges to read and write to this directory: touch /hosts/ <remote_machine>

/usr/discreet/clip/deleteme .

3 If error messages appear, verify the permissions in /etc/exports on the server machine. Read and write

permission must be given to the hosts. The appropriate line should look similar to the following:

/usr/discreet/clip *(rw,sync,no_root_squash

Verifying that NFS and Automounting Daemons are Running

These daemons are installed and running by default. Use the following procedures to verify that these

daemons are running. Network File System (NFS) and automounting daemons (AMD on Linux) must be

running for Wire transfers to work. To start NFS and AMD:

1 Run: chkconfig --list | grep nfs and then chkconfig --list | grep amd

2 Verify that NFS and AMD are set to “on” for run levels 3,4, and 5.

3 If NFS or AMD is off on any of those run levels, run: chkconfig nfs on and chkconfig amd on

4 Restart your network: /etc/init.d/network restart. You might also consider rebooting your

workstation.
