Fraggle put this into my mailbox:
Well, today I installed that patch on Sparc10 and proceeded to copy and paste the ping command from this message... I just got done reinstalling the OS and reconfiguring the machine. After I executed the ping, my machine not only rebooted but was unable to load the kernel after that.
I'm going to hazard a guess that you were unable to load the kernel because of a disk or software problem, not because of anything the ping bug or patch did. I installed this patch on a Sparc 5 running Solaris 2.5 last night. Note that since it replaces kernel drivers (in /kernel/drv), not the ping binary itself, you need to reboot in order for the fix to take effect. I tested this by installing the patch and pinging the machine (with the PoD args). It paniced, came up again, and after that was invulnerable to the Ping of Death. We'd installed the wrapper (the one that forces an -L on the commandline) a week or so ago, and decided the best course of action would be to leave it wrapped until we could be sure all the machines had been rebooted. Then we would remove the wrapper and reinstall the original binary. -dalvenjah -- Dalvenjah FoxFire (aka Sven Nielsen) I once heard the voice of God.
