Expect script + automated telnet process between three Linux machines

Is it possible to do the following by expect script? I have Linux server that connected to **linux_machine1** and **linux_machine1** connected to **linux_machine2** My Linux server have access only to **linux_machine1** ( linux server can telnet to **linux_machine1** but can’t telnet to **linux_machine2** ) But from **linux_machine1** I have access VIA telnet to **linux_machine2** So my question is: I need to develop expect script that perform telnet from the Linux server to **linux_machine1** then expect will perform telnet to **linux_machine2** from **linux_machine1** and will copy the **/etc/hosts** file from **linux_machine2** to my Linux server Is this scenario can be implemented by expect script? Short example that descript the process: ( run expect from Linux server ) --> linux_machine1 --> linux_machine2 Linux server <-- /etc/hosts from linux_machine2 <-- * remark - expect script need to be activate from the linux server
