Like Graham, I too would like to thank Alex and Dave for their detailed discussion of sockets. I tried Dave's small handler and it worked well, but only once. I went into the script to insert a break point so that I could step through it to see how it works, but it wouldn't work a second time. Even after I took the break point out, it still wouldn't work.

People will want their money back. :-) The server script appears to be still running here, but I'm connecting over an internal network, and so use a different IP address from the one in the script I posted. You'll have noticed a complete lack of error checking in the script I posted, and also on the server script if you managed to retrieve it. Error checking is lesson 2. :-) Unfortunately, I have to go Christmas shopping shortly (I promised), so I can't do much right now. You could add a socketError handler to the script. The sample handler in the Rev docs (under socketError) should be fine. Setting a breakpoint may not be so useful. I haven't tried this recently, but in the past I found it difficult (impossible) to use the debugger with asynchronous behavior like this. Instead, you might want to add lines to the script that record values to another field. For example, add the following log handler on logit pData put pData return after field log end logit and then add log sttaements wherever you want to inspect something. For example: on readLineOne pS logit readLineOne pS ##DEBUG read from socket pS for one line with message readmore end readLineOne Cheers Dave ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Re: Sockets
This time I'll try to be more helpful. On 11 Dec 2005, at 21:34, Graham Samuel wrote: Sockets, do we need them If you just need to connect to internet URLs, you can use the get URL, load URL, etc, calls, and not have to know anything about sockets. But if you want to do something more fancy, such as build your own web server, mail client, or completely new internet protocol (see below), then you probably need to know a little. (But I can tell you from my involvement with libUrl, you don't really need to know that much, at least if you're doing these kind of things in Rev.) and is the term just a token or does it carry some metaphorical meaning? Both of those I guess. The term socket is not just a Rev expression, but is used in all computer development environments. A socket is part of the connection that computers use to communicate with each other on TCP/IP networks such as the internet and on intranets too. The following description/analogy may not be strictly accurate, but I've found it quite helpful. Remember those old-fashioned telephone switchbords where the operator stuck wires into various holes on the board. Well, imagine your computer has a similar board inside with a lot of holes numbered from 1 to 65000 or thereabouts. And the computer you want to connect to (for example, the computer that hosts www.runrev.com) has a similar set of holes. To connect your computer to the runrev computer, you can imagine connecting a wire in one of the 65000 holes in your computer and connecting it one of the holes in the RunRev computer. The sockets are the endpoints of the connection. However, with Rev, we don't really need to think about the endpoints too much, and it is often easier just to think about the connection itself. However, much as I'd prefer to script this: open connection to www.runrev.com you have to script this: open socket to www.runrev.com #(not quite correct, but see later) Now remember those 65000 or so holes on the board in your computer, and the other 65000 holes on the renRev computer. Well those holes are called ports, which is easy enough to understand. So are sockets and ports the same? Not exactly as you can open many sockets to a single port (Many wires to one hole). But from a Rev perspective, they're pretty similar. Unfortunately, when you want to connect to the runrev computer, you can't just connect to any old port (numbered hole) on the runrev computer. Many of the ports have specific functions, and you have to connect to the right one. For example, if there is a web server running on the runrev computer, it is most likely linked to port (hole) number 80, as that's the default for web servers. So when you do something like this: get url http://www.runrev.com/index.html; libUrl assumes that the htpp server is running on port 80, and so does the following as part of its stuff: open socket to www.runrev.com:80 (You *must* include the port number when you open a socket, which is why the example earlier was wrong.) OK. So once you open a socket, what do you do? Well, you write data to the socket, and read data from it. (That's about all you can do.) If your connecting to a standard server such as a web server, mail server, or ftp server, there are protocols which dictate exactly what you have to write and read. These protocols are described in documents called RFCs which are no fun to read but will help send you to sleep when you're on a long flight. (Threaten the kids with one for Christmas!) So rather than wrestling with an established protocol, it's probably easier to learn sockets by inventing a brand new protocol. (Really.) But to do this, you have to build the server part of the connection too. However, this is amazingly easy. The key syntax to running a server, is the following script: accept connections on port port number with message some handler But if you want to see how simple this can be to get started, you can try running the following client script. I have a Rev server running here right now that implements a simple protocol I invented while writing this mail. :-) To run the client, you need to make a stack with two fields and one button. Name the fields in and out. Put some text in field in (keep it below 10K to save my bandwidth). Put the following script in the button: on mouseUp put 193.109.51.205:8081 into tS open socket to tS with message connected end mouseUp on connected pS put field in into tData ##uncomment following line to see server script ## write script cr to socket pS write length(tData) cr to socket pS write tData to socket pS with message readLineOne end connected on readLineOne pS read from socket pS for one line with message readmore end readLineOne on readmore pS, pData if word 1 of pData is a integer then repeat until length(tRD) = word 1 of pData read from socket

It seems like it is just that the messages are not always finding their way back to my callback handler (in Windows XP). Is this a problem, or is there a better way? If the devices are responding to the ip address and port that sent the query, then this might be your problem: The doc is lacking on using UDP. The callback for 'open datagram socket' is not for open. (It would be sent immediately, if it was.) It is for read. Scott Raney says to use that instead of read. If the devices are not responding to the port that sent the broadcast, but to some specific port then I guess the above does not apply; you would be using accept. If the messages are very large or a very large number comes in at once, then Windows will lose some. There are some system parameters that can be tweeked, but I forgot what they are.

Re: sockets and Windows behavior
On Feb 11, 2005, at 10:48 AM, John Rule wrote: I noticed that when a socket (regular or datagram) is opened to Windows (via my app that is listening on port 1901), an 'alias' port is given instead of the 'real' one. For example, if my external device (computer, PDA, etc.) connects to socket 192.168.77.10:1901 for communications, the actual socket reported is a random number (like 1407), and it changes each time the device connects (incrementally..1408, 1409, 1410). In TCP/IP both TCP and UDP uses the notion of ports. TCP uses connections and might be easier to explain. When computer or device 10.0.0.1 makes a TCP connection to port 1901 on 192.168.77.10, it needs to assign a port on 10.0.0.1. In most socket APIs the program requesting the connection may specify the port to use on 10.0.0.1, however in most cases it does not and the communications system assigns it. The connection if fully specified by the two address-port pairs. Typical socket implementations exploit that and allow multiple connections to a passive (listening) end. Those are all distinct. So a connection (from the view of 10.0.0.1) is specified by this: Remote IP address = 192.168.77.10 Remote port = 1901 Local IP = 10.0.0.1 Local port= 1407 Every IP packet has similar information in the header In Revolution when a connection callback (message) comes in, the IP address and the port of the other end are provided. If the connection is broken (or not, actually) and the other end makes another connection it is likely to be using another port. Ports must wait a short time before they can be reused, so typically systems just go to the next one if a port is not specified. There are cases in which the process opening the port needs to specify the port or at least find out what it is. Unfortunately there is no way to do that in Revolution. For most protocols this is not needed. Since Revolution hides the local port number, if you make multiple connections to the same listener, you need to specify an socket id name or number in the open. On the other hand, Revolution accept has no way to specify the IP address on a multihomed system. If you are listening on both TCP and UDP on the same port number, they can be confused in Revolution. UDP is connectionless, but is often handled as though it is a connection in sockets implementations and especially the view in Revolution. The same concepts apply roughly. (UDP is sort of a stepchild so folks don't worry about getting it right. Windows XP handles UDP errors poorly. Most Unix systems don't broadcast in a way consistent with the intent of UDP; I argue it is wrong.) If I missed what you are getting at, I apologize and will try to target that.

Re: sockets and Windows behavior
Thank you for the detailed responses everyone! To make my task even more difficult, I was trying to do a UDP broadcast, and accept a variable number of responses (unspecified number of devices). What became confusing was 'when' to parse the data parameter and when to use the 'with function' call. It was even further complicated by when the devices responded (when the socket is opened, or when the 'poll' is sent). It turned out to be a combination of several things...loads of fun.

If B or C, the client will need to point to the public address of that server for that service. The firewall will use NAT (network address translation) to translate addresses (and ports). One form is sometimes called masquerade; it represents to the Internet all private addresses behind the firewall as (typically) one address and ports are shuffled about to accommodate collisions. This almost always applies to clients behind the firewall. Servers are handled a couple ways. One is a fixed NAT in which a public address is assigned to the whole port space of a computer. An address on the outside is mapped directly to a private address. Another method is to assign a port on the public side of the server to a port on the private computer. This keeps the public addresses down. If the server is behind a firewall, it will normally be handled one of those two ways. The simple SOHO routers usually make it easier for the latter. This works well for an environment that uses masquerade, even for a computer supplying a service. Because of the kinds of things I do for customers, I usually have the first. At my lab, I mix all of the above methods. So, depending on the situation, you may have to fiddle with the router.

Anything else I can try? Make sure you can ping your own address (not just 127.0.0.1) and the other address from the client and the server. You can use netstat on OS X and Windows to look at the connections. You should be able to see the server listening even without a client. When a client is connected you should be able to see that on either machine (tcp). If your system uses DHCP (or similar method) to assign addresses, they might change between boots. Whoops! I saw you said the addresses are router assigned. Watch for this. Some computers might have a personal firewall. Though unusual, two computers on the same ethernet might not be on the same subnet. There are a few ways this can cause trouble if this is the case. If you have trouble with netstat or ping, holler. Many on this list have used them. Arg. I need to read better. I also saw, in looking back, that the client looks like it connects. What platform(s)? What Rev versions? Recent chat demo stack? Are any of these computers very slow or virtual PCs?

RE: Sockets
Perhaps a slightly different slant but I beleive the IP address of any computer is 127.0.0.1 as well as the given IP number (either statically or dynamically assigned). This is what I use in development (for Rev, Dreamweaver, IIS etc) and it works fine. I guess it depends on what your trying to do, if you can expand a little then more suggestions may be offered. Personally, I use multiple Rev stacks on the same IP number but different HTTP ports. This works fine for what I want to do. eg Rev (server) loads a web page to Explorer (client) on 127.0.0.1:8181 and reply is then captured by Rev listening on this port. In this case there's no reason why the client can't be Rev.

How fast is your XP compared to your net? At the same open where I can't write in the problem I'm seeding, I also don't get an open callback. The socketID is in openSockets and the other end thinks it is open and my realtime tcp watcher thinks it is open.
