Socket emergency

Hi,

I’m sorry about the mistake, this is a typo. Please refer to the following
code:

irb(main):018:0> t = TCPSocket.new(‘127.0.0.1’, 110)
=> #TCPSocket:0x2b28320
irb(main):019:0> t.readline
=> “+OK POP3 Server Ready\r\n”
irb(main):020:0> t.send(“USER xrfang@172.18.2.1\n”, 0)
=> 23
irb(main):021:0> t.readline
=> “+OK\r\n”
irb(main):022:0> t.send(“PASS xrfang\n”, 0)
=> 19
irb(main):023:0> t.readline
=> “+OK\r\n”
irb(main):024:0> t.send(“STAT\n”, 0)
=> 5
irb(main):025:0> t.readline
=> “+OK 5 10631\r\n”
irb(main):026:0> t.send(“RETR 1”, 0)
=> 6
irb(main):027:0> t.readline

After the final readline, it hang up again. I don’t know the exact
difference between t.readline and t.recv, but they both hang.

Thanks,
Shannon

try to use

  t.send("USER xrfang@172.18.2.1\r\n", 0)
