>Description:
Hi,
I'm using stream sockets for client and server communications
and have found a problem with data sent from FreeBSD to
any other platform (Solaris,WinNT,BSDi,etc). When the data
has a size in the range 101-207 bytes, the receiver gets
only 100 bytes. By the way, I was using blocking sockets
and if I tried to read data again on the receiver side (other then FreeBSD),
read operation can't succeed because apparently no data left for reading.
There might have been some settings when we built our kernel,
but I couldn't find anything.
Your help will be appretiated.
Thanks.
>How-To-Repeat:
On the server side (FreeBSD)
=====================================
theSocket = socket(AF_INET, SOCK_STREAM, 0);
theAddress.sin_port = htons((unsigned short)kPort);
theAddress.sin_family = AF_INET;
bind(theSocket, (struct sockaddr *)&theAddress, sizeof(theAddress));
listen(theSocket, 5);
len = sizeof(theAddress);
hisSocket = accept(theSocket,(struct sockaddr*)&theAddress, &len);
send(hisSocket,buffer,105,0);
...


On the client side (any other platform)
=====================================
s = socket(AF_INET, SOCK_STREAM, 0);
ent = gethostbyname(kServer);
addressRec.sin_port = htons((unsigned short)kPort);
addressRec.sin_family = AF_INET;
addressRec.sin_addr = *((struct in_addr *)ent->h_addr);
connect(s, (struct sockaddr *) &addressRec, sizeof(addressRec));
l=recv(s,buffer,sizeof(buffer),0); /* only 100 bytes read */
...
