iSCSI packet generator

[italienisch1987]

Hi

I have two virtual machines. One is a client and other is sever (SAN). I am 
using Wireshark to analyze the iSCSI protocols between client and sever.

Someone recommended me, in addition to a packet analyzer, I can also use a 
packet generator. Any good packet generator for iSCSI client/server model?

Thanks

Your question is not clear, but I'm *guessing*  you are asking if you can 
use some sort of software to inject iSCSI packets into your client/server 
stream, e.g. so that you can simulate errors and see how your software 
handles them?

If so, then the answer is no, there is nothing I know of.

Such "bad command injection" can be done with fancy hardware analyzers. A 
good (expensive) network analyzer can (I believe) inject bad packets of any 
type.See https://www.firewalltechnical.com/packet-injection-tools/

It sound like none of this is directly related to open-iscsi, though.

Hello,

 Can you provide a little more info?   iSCSI is for storage, so unless your
'server' is running an iSCSI target service there won't be 'iSCSI' traffic
to monitor.

 If you do have an iSCSI service running then providing a disk via that
service to the 'client' then doing normal I/O to that iSCSI disk will
provide all the traffic you will typically need.  I.e. discovering the
device, formatting the disk, doing writes and reads, etc.

 What is it that you are trying to do?   iSCSI is the transport for SCSI
commands over a network.   You can use SCSI tools to generate SCSI commands
to that disk, then the iSCSI initiator on the 'client' will create the
respective iSCSI packets.

 Regards,
Don
