block some www sites

[baraozemo]

Hi,

I have the 2.97 firmware installed in my DSL 2640T

I need help to understand how block of some websites using the routertech firmware.

for example: I want to block
http://www.facebook.*
http://www.orkut.*
http://www.twitter.*

Try this, from telnet/ssh login prompt

Code: Select all

block.sh facebook.com
block.sh orkut.com
block.sh twitter.com

tks...

Code: Select all

/var # block.sh
Syntax=block.sh <host> [NEW_IP]
Examples:
block.sh site1.com               [redirects site1.com to default IP (127.0.0.1)]
block.sh site2.com 128.128.128.0 [redirects site2.com to 128.128.128.0]


/var # unblock.sh
-sh: unblock.sh: not found

and what is the command to "revert" (unblock) ?

i tried that it did not work
even after a router restart

then logged in with winscp and went to the etc\hosts file and added the entry manually after a restart it was wiped clean
i'm now doing it again and will see if "save all" (saving all settings to flash) will keep settings between reboots

questions
1 . if the block.sh script had worked then do you need to run it each time via cron or some routine each time the router reboots ?
2. is there an easy way to block ip ranges ? or filter traffic using mime types
i'm looking to block

• *facebook.com/ajax/chat*
  *facebook.com/images/chat*
  *facebook.com/ajax/presence*
  *.channel*.facebook.com/x/*/false/p_*

[thechief]

Well, it should work. Did you clear your browser cache, etc., etc.?

1 . if the block.sh script had worked then do you need to run it each time via cron or some routine each time the router reboots ?

Yes.

2. is there an easy way to block ip ranges ? or filter traffic using mime types

No idea.

[baraozemo]

what is the correct step to block sites.

for example:
block.sh facebook.com
after, is necessary to save/reboot the modem ?

or only "save" ?

[thechief]

block.sh facebook.com
after, is necessary to save/reboot the modem ?

No. The command should take effect immediately.

or only "save" ?

No, you cannot "save" it. The changes will be lost on reboot, unless you run the command on every boot-up (e.g., via the autoexec functions).

[baraozemo]

ok, is this the correctly way ?

(to install the filter in the boot / allways use it)
setenv autoexec.sh "block.sh facebook.com"
setenv autoexec.sh "block.sh orkut.com.*"
setenv autoexec.sh "block.sh twitter.com"

(to uninstall the filter)
unsetenv autoexec.sh "block.sh facebook.com"
unsetenv autoexec.sh "block.sh orkut.com.*"
unsetenv autoexec.sh "block.sh twitter.com"

[thechief]

setenv autoexec.sh "block.sh facebook.com"
setenv autoexec.sh "block.sh orkut.com.*"
setenv autoexec.sh "block.sh twitter.com"

Wrong. You are simply overwriting the environment variable with different values. Only the last one will count. If you are going to block a lot of sites, you should create a script, and upload it to a minix partition on the router. If you can it "startup.sh", it will be executed automatically during bootup. If you are only going to block a few sites, you can do something like

Code: Select all

setenv autoexec.sh "block.sh facebook.com && block.sh twitter.com && block.sh orkut.com"
setenv autoexec1.sh "block.sh blah_blah && block.sh bloo_bloo && block.sh blee_blee"

You can have up to autoexec7.sh

(to uninstall the filter)
unsetenv autoexec.sh "block.sh facebook.com"
unsetenv autoexec.sh "block.sh orkut.com.*"
unsetenv autoexec.sh "block.sh twitter.com"

Unsetenv takes only one parameter - and, the second and third commands are doing nothing, since you have already unset the single variable.

So i try to block all country using cc_allow and add my country code and restart my firewall , i try to access the ssh using a vpn and still i can access my server..

Note, this is only a temporally block.. i will use filter block once done..
