We are having an issue with all of our Solaris VMs. The issue we're seeing is frequent timeouts when when connecting via SSH or HTTP. It only seems to affect initial connections... when I connect via SSH it will hang and timeout before I even get the login prompt, however if I CTRL C it and try again it connects just fine.
I logged into the VMware console and ran the snoop command on the Solaris VM to get a packet capture when this occurred. Here is the capture.
My computer is 10.0.0.3 and I removed the hostname of the Solaris VM I'm connecting to.
Based on the packet capture, it looks like the VM sees my first SYN packet, but does not reply, prompting my computer to resend it. It then decides to reply with an ACK packet, which I believe should've been a SYN ACK packet. Then it looks like it sends a SYN ACK packet.
Does anyone know why this is happening? Our Cisco ASA firewall waits 30 seconds and then tears down the connection because of the SYN timeout.
Thanks in advance for any help.
