Hello all
I use Starport 5.5 on Windows 7. I have error when connect to Sun Storage 7000 running in VirtualBox. Error "Failed to connect to remote server. Server may be refused network conections. You may need to check firewall settings". I also try in XP and have error too. I send logs to support, they replied that I wrote here. Microsoft initiator work good.

iSCSI initiator requires port 3260 to be open. MS iSCSI Initiator creates such rule in firewall for itself during first run. Try to create another one rule specially for StarPort.

Is there any way for you to catch Sun-side logs or run Wireshark on the Windows box to capture network traffic for us?

see log1.txt in log1.zip. This is wireshark log filter for port 3260. 192.168.56.1 - my system with windows 7 x32, 192.168.56.2 - remote Sun storage 7000 in virtualbox.

Hi,
Could you upload the logs in the pcap format?
Thank you in advance.

Thank you!
From the last log I saw that StarPort repeatedly tried to negotiate its DefaultTime2Wait=5, but the target each time answered with DefaultTime2Wait=2 and so on until StarPort given up its attempts.
According to the iSCSI specs the DefaultTime2Wait is a "max number value", so the target must use the value proposed by the initiator (5) in its replies.
It looks like the target's implementation of the iSCSI specs is not correct.
Is there any way to set the DefaultTime2Wait=5 on the target side?
This should solve the problem...
