Re: [U2] Sockets programming on Unidata
Are you the client or the server? acceptConnection is only used by the
server to accept incoming socket connection requests. If you're trying to
communicate as a client to a remote server, you won't use
acceptConnection, you'll just open the socket, write the request, read the
response, and close the socket.

Unidata 7.1.8
HP-UX 11.11i
I am attempting my first sockets programming project. It appears that
'initServerSocket' and 'openSocket' are working OK.
'getSocketInformation' returns info.
But 'acceptConnection' only seems to timeout, yet it returns a RESULT of
'0' (no error). The SocketHandle3 variable is not set.
Without this SocketHandle3 variable I cannot read ('readSocket'). I am
doing a 'readSocket' after I have done a 'writeSocket' I am expecting a
reply from the remote application (Oaisys call recording).
What am I missing? The Unidata manual is pretty sparse. Maybe I have an
issue with network permissions/firewalling?
Any ideas on what may be going on with 'acceptConnetion' ? Maybe you
have links to deeper Rocket documentation?

Re: [U2] Sockets programming on Unidata
Got it, I am the client - so the 'init' and 'accept' not applicable.
So I should both 'write' and 'read' using the same SocketHandle?

RE: [U2] Sockets Universe Question
Adrian, Thanks for the suggestions. Ive never run nmap before, this is good to know about. I have discovered that I plugged the routers into the 'inside' of the firewall. They should have been on the 'dmz' side. So, I have corrected that and we still have issues. For the time being, it appears to be a network config issue rather than a Universe issue. Hopefully, I will get to the 'simple' part that you describe soon. Thanks Anthony -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adrian Merrall Sent: Monday, October 16, 2006 11:00 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] Sockets Universe Question Anthony, Yes I can ping it from the server running Universe from the linux prompt. I did not set up a route. I believe the default route should work. I will look into that one. Thanks for the suggestion. Anthony If you can ping the server then your routing is should be OK, especially as you are doing from the lnx box running Universe. A common problem is firewalls (esp. corporate rather than home linksys type ones) tend to limit outbound connections and only allow outbound connections to port 80 etc. One way to test this would be to do as David suggested and try to telnet to that port (telnet ipaddy port (e.g. telnet 123.456.789.100 8080) As you are on linux you also should have the excellent nmap tool. Try something like nmap ipaddy - you have to run as root to have access to some of the options but this will port scan the remote box and let you know the ports they are listening on. Note you may want to let the bank know as people can get a bit excited about port scanning as it is often the first step in a remote instrusion attempt. Good luck, once you can get through my experiance is the unibasic socket api works very well for the simple stuff.

Re: [U2] Sockets Universe Question
Anthony, If you are the client (ie contacting the bank) why are you using initserversocket? Initserversocket creates a process to listen for incoming connections binding to one of your local IP addresses (eg 192.168.1.1 from your example). To connect to the bank you need to use opensocket eg: ERR = OPENSOCKET(123.123.1.1, 4215, 1, 2000, SKTHDL) HTH, Craig --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] Sockets Universe Question
You're right Craig. The reason is simple - I dont know what Im doing yet. When I do, Bob will be my uncle as they tell me. Ive never done this before. I am actually trying to help the programmer here (blind leading the blind). By the end of the week, we will right where we need to be in terms of understanding this. Thanks for the Help Craig. I appreciate it.

RE: [U2] Sockets Universe Question
Mongo only pawn in game of network addressing, but isn't' 192.168.1.1 only valid inside your router firewall?

RE: [U2] Sockets Universe Question
The solution might be very simple; if you don't specify an ip address in the initServerSocket, it defaults to the address of this server. When you do the acceptConnection, the requestor is sending their IP address. If this doesn't work, then perhaops the problemis an external one - firewalls, NAT's, that sort of thing.

RE: [U2] Sockets Universe Question
We have a point to point line intalled with a router that is configured to take care of that. The numbers I used in my example are not real. The ip addresses are as different as in my example, but they are not real. Do you think this matters ?

Re: [U2] Sockets Universe Question
Anthony, Yes I can ping it from the server running Universe from the linux prompt. I did not set up a route. I believe the default route should work. I will look into that one. Thanks for the suggestion. Anthony If you can ping the server then your routing is should be OK, especially as you are doing from the lnx box running Universe. A common problem is firewalls (esp. corporate rather than home linksys type ones) tend to limit outbound connections and only allow outbound connections to port 80 etc. One way to test this would be to do as David suggested and try to telnet to that port (telnet ipaddy port (e.g. telnet 123.456.789.100 8080) As you are on linux you also should have the excellent nmap tool. Try something like nmap ipaddy - you have to run as root to have access to some of the options but this will port scan the remote box and let you know the ports they are listening on. Note you may want to let the bank know as people can get a bit excited about port scanning as it is often the first step in a remote instrusion attempt. Good luck, once you can get through my experiance is the unibasic socket api works very well for the simple stuff.

Since two years we're using jd3 on live sites and it works ! Easily with only 5 jd3 client, a website is serving about 250.000 pages per month. Don't you think that flashconnect is using socket to communicate ? Cedric is referring to a comment I made at that link. I don't want to get into a heated discussion about D3 socket connectivity in a U2 forum, but this is a well known topic which has been discussed elsewhere and it may affect U2 users who work with sockets too. If an MV process dies while it has the handle to a socket server open, the host OS doesn't know about it immediately and may not be able to release the socket resources until the MV DBMS is restarted and MV memory and other resources are released. That means the one and only port that all users rely on to connect into goes non-responsive, and you may need to reboot all users in order to get your connectivity back on one line. This is entirely unacceptable. The fact that MV can't fork or pass handles to child processes to handle web/socket requests compounds the issue because it makes all operations single-threaded unless you have client code that's intelligent enough to do a round-robin among multiple server sockets. FlashCONNECT acts as a client to a middle-tier server, FC is not a server at the DBMS level. You have 64000 socket ports that you can use, so a dead connection is no big deal unless you lose many of these each day. D3 *nix behaves better than D3NT in this regard, and Universe and Unidata will have their own considerations across platforms and releases. The rule of thumb is to trust but verify, and don't simply assume that sockets are a universal solution - pun intended I guess. Comments from someone with a U2 clue are welcome.
