Hi all, Thanks to the input from many on this list, I've got VMware up and running quite nicely on my Linux box. This is allowing me to set up a nice little self-study networking lab. However, I'm running into some annoying problems. I'm running RedHat 6.2 with kernel 2.2.14-5SMP. I've currently got: 1 Netgear FA-310TX [tulip] 10/100 3 RTL8139 generics 1 good old fashioned IBM Token Ring II adapter (ISA) vmnet 1 & 3 (host-only VMware) All come up and generally work, at least for a bit. I seem to start getting various errors on the Token Ring card after it's been up for a while, and tonight I noticed a lot of "kernel: eth3: Tx queue start entry 4 dirty entry 0" messages in my syslog output. I'm wondering if I've hit some limitation with Linux and networking. Is there a limit of concurrent NICs in 2.2? Also I noticed problems using Zebra with multicast and MTU sizes over the token ring. Anyone a Token Ring/Linux wiz? I think I'm OK for interrupts: /proc/interrupts: CPU0 CPU1 0: 404095 402615 IO-APIC-edge timer 1: 3410 3513 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 3: 38 56 IO-APIC-edge serial 4: 4 0 IO-APIC-edge serial 6: 13 15 IO-APIC-edge floppy 7: 794 739 IO-APIC-edge ibmtr 8: 12512 10465 IO-APIC-edge rtc 9: 7920 10743 IO-APIC-edge soundblaster 11: 20551 20471 IO-APIC-level eth0, eth1, eth2 12: 42018 43259 IO-APIC-edge PS/2 Mouse 13: 1 0 XT-PIC fpu 14: 432521 435114 IO-APIC-edge ide0 15: 8257 7742 IO-APIC-edge ide1 NMI: 0 ERR: 0 It's truly amazing stuff, but these "once in a while" problems are driving me nuts! Any tips/info appreciated. Thanks, - Bob
