I'm trying to use Curl to monitoring some web site
connectivity from our network.

I installed smokeping on RH Linux AS2.1 and want to
use Curl probe to fetch the entrance web page every

It works with some web site like google, but it always
returns 100% loss with web site like:
http://www.sina.com.cn, http://www.sohu.com,
http://www.nytimes.com. The curl version is:

$ /usr/local/bin/curl --version 
curl 7.12.3 (i686-pc-linux-gnu) libcurl/7.12.3
OpenSSL/0.9.6b zlib/1.1.4 libidn/0.5.9
Protocols: ftp gopher telnet dict ldap http file https
Features: Debug IDN IPv6 Largefile NTLM SSL libz 

The configuration is:

*** Database ***

step     = 300
pings    = 20

*** Probes ***

+ FPing

binary = /usr/local/sbin/fping

+ Curl

binary = /usr/local/bin/curl 

*** Targets ***

probe = Fping

menu = Top
title = web page speed
remark = Welcome to our web page fetching speed page.

+ Net-Service

++ Sina

menu =  Sina
title = Connecting Speed from HZTele-IDC to SINA Web
host = www.sina.com.cn
probe = Curl
agent = "User-Agent: Mozilla/4.0 (compatible; MSIE
5.01; Windows NT 5.0)"
url = http://www.sina.com.cn

With "time curl http://www.sina.com.cn" it shows

real    2m52.090s
user    0m0.010s
sys     0m0.020s

How can I deal with such problem?
