227 Entering Passive Mode (159,153,197,77,194,82)

how would i get the ip address from this string replay message. and convert it to InternetAddress....

Answer 1

227 Entering Passive Mode (h1,h2,h3,h4,p1,p2) is the syntax, h1-h4 are the 4 bytes of the ip address, p1 and p2 is a 2 byte port number, but i don't see how you'd convert that into an rsc822 internet address, which is in the local@domain form. Oh and btw you can use string.substring(27,string.length-2).split(",") to get the params as seperate strings, then use Byte.parseByte(string) for each of the values
