Siva/Moinak, Here is an update on what I observed yesterday :
- The scripts pick up the default DNS servers provided by TataIndicom. I found that the DNS servers stopped responding after sometime (approx 1 min.) - So, we added Ip addresses for a few locations in /etc/hosts and things started working well. Also, we added the public DNS servers as well. This worked for a while. However, later we observed that things stopped working and after multiple restarts things worked but were flaky. Now, from my observations I think there are a few factors which could be affecting this : - As Siva said there could be problems with the negotiations that Solaris does. I am not convinced because, when I tested it on another laptop here and it stayed up for atleast a couple of hours. - There is something in Solaris network stack which does not work well. Again I am not convinced because, when I ran snoop I saw that the pkts were being sent out to the router configured. (Unless snoop was faking it :-) - The signal strength could be varying and probably we are dropping the link often. I say this because, I saw that the modem did show Amber light occasionally (which I presume is an indication that it is negotiating). - The USB port/connection could have problems. I learnt that it is engineering piece. We found that the trackpad had some issues. It would really interesting to debug this issue. Also, it would be useful to hear from other who have used similar configs. Thanks and regards, Sanjeev.
