First, make sure you can do a non-STAF ping from your desktop to the VM's
IP address (if that doesn't work then you have a TCP/IP configuration
issue).
If that works, then try increasing the select() timeout for the STAFTCP
connection provider. The STAFTCP connection provider's select() timeout
is based on the CONNECTTIMEOUT (specified in milliseconds) which defaults
to 5000 (5 seconds).. Try increasing the CONNECTTIMEOUT and see if that
resolves the problem. For example, on your laptop, modify the STAF.cfg
file (in C:\STAF\bin) by adding the CONNECTTIMEOUT option to the ssl and
tcp interface lines. For exxample, to increase the ConnectTimeout to 30
seconds:
interface ssl library STAFTCP option Secure=Yes option Port=6550 option
ConnectTimeout=30000
interface tcp library STAFTCP option Secure=No option Port=6500 option
ConnectTimeout=30000
Section "4.3.2 STAFTCP Connection Provider" in the STAF User's Guide at
http://staf.sourceforge.net/current/STAFUG.htm#HDRNETWORKCFG talks about
the CONNECTTIMEOUT option as follows:
CONNECTTIMEOUT=<Number> specifies the maximum time in milliseconds to wait
for a connection attempt to a remote system to succeed. The default is
5000 (5 seconds). You may need to increase this value if you are
consistently receiving return code 16 when trying to communicate with
distant STAF systems. Note that the total time to wait for a connection to
a remote system to succeed is (CONNECTTIMEOUT * CONNECTATTEMPTS) +
(CONNECTRETRYDELAY * (CONNECTATTEMPTS - 1)). If using the defaults, the
maximum total time to wait for a connection to a remote system to succeed
is (5000 * 2) + (1000 * 1), which equals 11 seconds. The CONNECTATTEMPTS
and CONNECTRETRYDELAY values are operational parameters that can be set in
the STAF configuration file.

Subject: [staf-users] Help Regarding socket connectivity
Hi all,
I created 4 VM’s and the staf is running on all of them. But the problem
is that I am unable to ping the VM using the staf ping command from my
desktop but the reverse is happening fine.
The error: C:\Users\Yashaswi>staf 192.168.20.199 ping ping
Error submitting request, RC: 22
Additional info
---------------
STAFConnectionReadUInt: select() timeout: recv() RC=0: 22
Help required ASAP.
