| |
Hi, all. I'm having problems with TCP stalls under kernel 2.0.0, 2.0.30, 2.0.33, 2.1.79, 2.1.85, 2.1.86 and 2.1.90-pre3. I have two machines connected via 10 Mbit/sec EtherNet. One of these (machine A) is also connected via SLIP (33.6 kbaud, 115.2 kbit/sec serial interface) to a departmental LAN and hence is the router for the other (machine B).
I get reasonable performance with TCP, sending from machines on the LAN to machine A. However, most times when I send a large amount of random data (say 10000 bytes) from a LAN machine to machine B, I get TCP stalls. These stalls last for at least 15 minutes (I give up after that).
I have tried the following kernels on machine A (the router): 2.0.33, 2.1.85, 2.1.86.
I've tried the following on machine B: 2.0.30, 2.0.33, 2.1.76 and 2.1.90-pre3.
I've also tried various LAN machines: 2.0.0, 2.0.30, 2.1.90-pre3 as well as Sun Sparc with Solaris 2.5.
It doesn't seem to matter what combination I try, I get these awful TCP stalls. Does anyone have any ideas for me to try out? I really need to get this going. I've tried sending via UDP instead, and that seems to be working fine.
Regards,
Richard....
