Hi
I would like to run multiple ssh commands within the same 'context' as if
it would be using putty when connecting to a cisco device.
Here are two examples of what i would need to send to the device:
1) Setting the terminal width to 0 in order to remove the line breaks. This
makes parsing the output of the following command easier.
Switch#terminal width 0Switch#show vlan brief
VLAN Name Status Ports
---- -------------------------------- ---------
-------------------------------
1 default active Et0/0, Et0/1, Et0/2, Et0/3
...
...
2) Configure an IP address of an interface. When connecting with ssh, I
start in the 'enable' mode due to the user privileges. I need to get in the
config mode first. Afterwards, I need to get in the interface config mode
and can finally set the address.
Router#configure terminal
Enter configuration commands, one per line. End with
CNTL/Z.Router(config)#interface e3/2Router(config-if)#ip address 172.16.1.1
255.255.255.0
I can run a single command easily with session.Run() but as I described, I
need to be able to run multiple commands and parse their output within a
single 'context'.
*How could this behavior be achieved with crypto/ssh?* When I try to create
a new session after the first session.run(), it always returns with an
error: "EOF".
I just wanted to try whether the context will stay the same but it won't
even come that far.
//create session 1 and go into config mode
session, err = client.NewSession()if err != nil {
panic("Failed to create session: " + err.Error())}if err :=
session.Run("conf t"); err != nil {
panic("Failed to run: " + err.Error())}
session.Close()
//create session 2 and go into if mode
session, err = client.NewSession()if err != nil {
//Error will be EOF
panic("Failed to create session: " + err.Error())}if err :=
session.Run("int e3/2"); err != nil {
panic("Failed to run: " + err.Error())}
session.Close()
Thanks,
Dominik
