Why curl showing permission denied in tizen sdb?

I'm trying to send http request using curl from tizen sdb.

I made a request like "curl -v example.com"

An got error message:

bash-3.2# curl -v example.com
* STATE: INIT => CONNECT handle 0x1e178d8; line 1398 (connection #-5000)
* Rebuilt URL to: example.com/
* Added connection 0. The cache now contains 1 members
*   Trying 93.184.216.34...
* TCP_NODELAY set
* Immediate connect fail for 93.184.216.34: Permission denied
* Closing connection 0
* The cache now contains 0 members
* Expire cleared
curl: (7) Couldn't connect to server

I can request using browser app. So, there is no problem with device's internet connection. I was also able to send http request from tizen native app using libcurl library. But from sdb shell, curl request isn't working. Can anyone help?

Solution

Thanks to of my colleague, I finally found a solution. Turns out permission needed be added before running binary in tizen 3.0 . Following commands needed be run in sdb shell (in root mode)

# mount -o remount rw, /
# chsmack -e "System" /usr/bin/curl
