Hi all
I’m having some trouble with Telnet on Ruby
I’m communicating with a server, and the response code is always
something like this:
FCX: ?>
FCY: ?>
FCY: ?>drive
FCY: drive>dylan
FCY: dylan>he
FCY: dylan>
FCX: ?>drive
FCX: drive>dyl
You switch interfaces between X/Y and Console by using Ctrl-T so that’s
fine
My code so far is:
tn = Net::Telnet.new(“Host” => “10.54.30.40”,“Timeout” =>
10,“Telnetmode”=>false,“Prompt”=>"/[.*>]/",“Dump_log”=>“C:/temp/dump.log”)
tn.puts(?\024)
tn.cmd(‘dylan stat’)
tn.cmd(“String”=>‘con sh’,“match”=>’ >’)
the responses are valid, and both the dump log and wireshark agree that
the response back from the server is
[block of data]
dump log extract:
0x00000: 43 6f 6e 6e 65 63 74 65 64 20 74 6f 20 31 30 2e Connected

How do I set up my prompt so that it gives me the correct responses and
doesn’t constantly timeout?
The response to my last message in the console was:
irb(main):046:0> tn.cmd(“String”=>‘con sh’,“match”=>’ >’)
Timeout::Error: timed out while waiting for more data
from C:/Ruby/lib/ruby/1.9.1/net/telnet.rb:558:in waitfor' from C:/Ruby/lib/ruby/1.9.1/net/telnet.rb:697:incmd’
from (irb):46
from C:/Ruby/bin/irb:12:in `’
Many thanks
Scott
