U mentioned site works with wget and browser, i am confused where u dont get this site, at the server or the clients, and how do u check the availability of the sites, i presume one use a browser to check it.
Traceroute may not always work at icmp etc. are blocked or droped on many sites, u want even be able to ping them.
The best way to get to know about these sites and this problem is try the command dig www.samachar.com on linux or on Win NT nslookup www.sify.com
Regards Yayati.
Problem: All sites are accessible at port 80 other than following sites: rbi.org.in samachar.com sify.com nsdl.co.in (traceroute case : But site works with wget and browser)

Yayati and Trevor, After Yayati pointed out about dig, I rechecked. The only thing which I can see is that rbi.org.in, samachar.com et-all, which I'm not able to access through browser/wget has their primary dns servers with
pdns.satyam.net.in sdns.satyam.net.in
Earlier I tried sending plain txt files but I hit 7 KB limit of the list, so now have created tar cvjf, hopefully this will go through. It contains one PROXY dir init.
with wget nsdl.co.in works while rbi.org.in does not. with traceroute both nsdl.co.in and rbi.org.in never reaches ip.
Can above two nameservers be problem? I donot know what else to look for. -Krishna

One of these sites (dont remember which ) requires that you declare ports 81-85 as safe ports in squid.conf. Another thing is mkae sure that ECN in turned of in your tcp settings. cat /proc/sys/net/ipv4/tcp_ecn if it is 1 set it to 0 echo "0" > /proc/sys/net/ipv4/tcp_ecn
All the best.

Clifford,
IT WORKED. echo "0" > /proc/sys/net/ipv4/tcp_ecn did the trick.
Trevor, Yayati and Clifford. I was struggling with this thing from last couple of days and night, I and my partner at Delhi have tried all permutation and combination. I was on the verge of compiling and downgrading kernel. (I'll do RTFM about this tcp_ecn thing.)
In next lug meet if we meet beer(s) are from me. -:) Thanks for all your help guys.
