[irda-users] server ias not responding?

[Erin R. <nr...@ma...>]

Hi, 

	I am still working on the problem with "no route to host" when trying
to connect to the server over irda stack.  But no luck!  I have looked
into the irdadump and various files in /proc/net/irda this time, and
here is what I have.

I am using my Zaurus as the ir server, as it blocks to accept
connections, 

*********in proc/net/irda/irias, it shows:

LM-IAS Objects:
name: Salutation-Lite, id=77594
 - Attribute name: "IrDA:TinyTP:LsapSel", value[IAS_INTEGER]: 16

name: Device, id=0
 - Attribute name: "IrLMPSupport", value[IAS_OCT_SEQ]: octet sequence (3
bytes)
 - Attribute name: "DeviceName", value[IAS_STRING]: "Linux"

*********and /proc/net/irda/irlmp:
Unconnected LSAPs:
lsap state: LSAP_DISCONNECTED, slsap_sel: 0x10, dlsap_sel: 0xff,
(Salutation-Lite)
lsap state: LSAP_DISCONNECTED, slsap_sel: 0x0, dlsap_sel: 0xff, (IrIAS
srv)

Registred Link Layers:
lap state: LAP_STANDBY, saddr: 0x74462a97, daddr: 0xffffffff, num lsaps:
0

  Connected LSAPs:

So, the name that's binded to my server socket is "Salutation-Lite", and
my server program is referenced at lsap-sel 0x10.  Seems fine.

My client runs on the laptop, and this is my section of the code after
creating the socket:
    struct sockaddr_irda address;
    address.sir_family = AF_IRDA;
    strncpy (address.sir_name, "Salutation-Lite:IrDA:TinyTP:LsapSel",
             45);
    address.sir_lsap_sel = LSAP_ANY;
    address.sir_addr = list->dev[0].daddr;
    printf("Connecting to: %x, %s\n", address.sir_addr,
            address.sir_name);
                                                        //
    if (connect (fd, (struct sockaddr *)&address,
           sizeof (address)) < 0)
    {
        fprintf(stderr, 
          "Connecting to the server failed. Error: %s %d\n",
        strerror(errno), errno);
    }

And it fails at connect, and I get "no route to host".

********So, I looked at the irdadump output on my laptop, and it shows:
400 [ Computer LAN Access ] (37)

22:32:11.176826 rr:cmd > ca=ce pf=1 nr=0 (2)
(more rr:cmd)

It seems like the laptop's snrm:cmd has succeeded over irlap, since ua
is received.  But, sending rr (receive ready) command to the Zaurus had
no responses, as the Z blocks at the accept command. 

******** When the client is running, in the /proc/net/irda/irlmp on the
laptop, I have :
Unconnected LSAPs:
lsap state: LSAP_DISCONNECTED, slsap_sel: 0x10, dlsap_sel: 0xff, (IrLAN
ctrl (p))
lsap state: LSAP_DISCONNECTED, slsap_sel: 0x0, dlsap_sel: 0xff, (IrIAS
srv)

Registred Link Layers:
lap state: LAP_ACTIVE, saddr: 0x94b085cd, daddr: 0x74462a97, num lsaps:
1

  Connected LSAPs:
  lsap state: LSAP_SETUP, slsap_sel: 0x11, dlsap_sel: 0x0, (IrIAS cli)

It seems like the client is trying to communicate with the ias server at
Z who is referenced on Z at selector 0x0.  I know that when connect() is
called, ias function is also called to resolve the selector associated
with "Salutation-Lite", but, how come the server ias is not
responding??  Can someone please give me some hints??  Thanks!
