Hello
Sorry for the delay in proceeding the discussion. I am back since 3 weeks, but I did not have the time to resume this evaluation.
I mentioned that my system administrator asserted, that ping uses TCP. But that was not true. I misunderstood him. Additionally I said, that my ping returns only "MyLaptop is alive". That was the case, because I translated only those ping arguments to the Solaris version, which were used in the command line sent by Neil Brown. Thus I had tried only the command "ping MyLaptop 8192 10". But now I can give you the correct output (with the "-s"):
Christoph: ping -s MyLaptop 8192 10 PING MyLaptop: 8192 data bytes 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=0. time=22. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=1. time=22. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=7. time=24. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=8. time=77. ms
----MyLaptop PING Statistics---- 10 packets transmitted, 4 packets received, 60% packet loss round-trip (ms) min/avg/max = 22/36/77 Christoph: ping -s MyLaptop 8192 10 PING MyLaptop: 8192 data bytes 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=0. time=29. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=3. time=123. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=4. time=36. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=5. time=23. ms 8200 bytes from MyLaptop (192.168.0.1): icmp_seq=8. time=60. ms
----MyLaptop PING Statistics---- 10 packets transmitted, 5 packets received, 50% packet loss round-trip (ms) min/avg/max = 23/54/123 Christoph:
So, there seems to be a network problem (50-60% loss).
Currently I do not have root access to the Solaris machine, thus I cannot play around with the mount options. But I requested a temporary root access, and I think I will get it in the next weeks. Then I will report again.
