Hi i want to know is there any command to transfer file from one server to a local machine in our office.

For example our server is 88.44.44.55 and our router's ip is 66.33.22.11 and my local ip is 192.168.1.1,
Now i want to transfer file from 88.44.44.55 to my own linux machine 192.168.1.1.

Is it possible???

Thanx In Advance

of course it's possible. I'd suggest scp to start with as the simplest way. Obviously you need to be able to reach one machine from the other first.

Thanx acid_kewpie
This 88.44.44.55 ip is provided by our broadband service provider.
Can u please give me example of command line in linux???

I want to write a script to automatically download backup from our server.

there are a lot of solutions, but mainly they are a pair of client-server applications.
So you can try scp, ftp, rsync, wget (these are the clients to work with), but all of them require a server (or at least some configuration) on the other side.
In general office can restrict the outgoing traffic and block incoming, so you need to set a server at home and run the client in the office. The router also should be configured to redirect the requests to your host.

I'm sure you can read the scp manpage for this, it's not hard to look up.

scp user@destination:/where/the/file/is/file.txt /where/the/file/goes

In destination which ip should b giver the local machine ip or 88.44.44.55?
When i paste 88.44.44.55 the reply is
ssh: connect to host 88.44.44.55 port 22: No route to host
lost connection

We have no idea how your network is set up do we? give us some useful information to start with and we can try to work it out. but it's a big jump from having possibly no connectivity to copying a file, so work out what your current problem is first, before trying to fix an unrelated one.

We download Backups from our server daily. Log files of radius and asterisk.
I want to write a script which automatically download files on our computer, Our server is in Germany and our office is located in Pakistan.
the service provider gives us 88.44.44.55 ip, and our backup computer which save backup have ip 192.168.1.1, now i want to transfer backup directly to our backup computer.
i m using this command scp blackup.out root@88.44.44.55: /root
but i m getting this error
ssh: connect to host 88.44.44.55 port 22: No route to host
lost connection

ok, that's repeating the stuff we DO know. how about the stuff we DON'T know? where does this public IP fit into it? Is internet involved etc..? what is the layout of your network? What security devices are involved? What device does this public IP reside on?

you can try traceroute 88.44.44.55 for example

This is the reply

so what IS 88.44.44.55?

This ip is assign to us by our internet provider.
Internet is involved.

I would try a port scan, which ports are open, what can you reach from the other side?
do you know nmap?
