@kusha: please provide some more details about your problem.
Where you change the TTL ? Which TTL are you talking about ? Model of your dreambox ?

Dude, TTL is in the dreambox folder via ftp. Default value is 64.

So you must go: /proc/sys/net/ipv4/ip_default_ttl/

I tried with puty-telnet with this comand:

echo 49 > /proc/sys/net/ipv4/ip_default_ttl

but it isn't saved!

Re: how to change TTL in dreambox

can you explrin what kind of benefit i have if i change ttl ?

Re: how to change TTL in dreambox

data packet drops after 64ms instead of 56ms so the latency is higher but the connection SHOULD be more stable.

Edit: he's using a lower value, so the packets are drop after 49 msec instead of 64, but this cause a higher traffic.

@enka: write a sh script and setup to run it at the boot...

Re: how to change TTL in dreambox

Faccione can you give more specific how to write a sh script and setup to run it at the boot. Any detail. Because I can't save value.

Re: how to change TTL in dreambox

create a a file ttl_49.sh and include the following code:

#!/bin/sh
echo 49 > /proc/sys/net/ipv4/ip_default_ttl
exit 0

save it in: /etc/init.d/

execute: update-rc.d ttl_49.sh defaults

change the attributes to be executable: chmod 755 ttl_49.sh


The sh script will (should) run every time you boot up and rewrite the value in the file.

Please report if it works or not.

I have a question for you: on which environment are you going to make this changes ? Dreambox 800, 7000, 7020, 500 ?

What you mean with "couldn't save ttl_129.sh" ?

On which way are you trying to save it ? any error ?

I suggest to edit the file using a text editor (notepad), push the file to the remote directory via FTP (filezilla) and change the permissions using filezilla or directly via telnet with the chmod command.

Re: how to change TTL in dreambox

I don't know how to ask permisions using filezilla or via telnet.

Show details.
