ipv6 messages in /var/log/messages

albert · Post by **albert** » 04 Aug 2007, 14:27

Seem to have spurious messages like these in /var/log/messages:

ipv6: Unknown symbol crypto_alloc_tfm
ipv6: Unknown symbol crypto_free_tfm

It doesn't seem to affect anything. But since I am not using ipv6 is there a quick way to get rid of these messages so I'll have a clean messages file?

Thanks,

Albert

This is the actual error I find:

Aug 6 06:30:55 beige modprobe: FATAL: Error inserting ipv6 (/lib/modules/2.6.16.16/kernel/net/ipv6/ipv6.ko): Unknown symbol in module, or unknown parameter (see dmesg)
Aug 6 06:30:55 beige kernel: ipv6: Unknown symbol crypto_alloc_tfm
Aug 6 06:30:55 beige kernel: ipv6: Unknown symbol crypto_free_tfm

Somehow, at 6h30 someting happened with which it wanted to load modules ipv6, which in turn has some non referenced symbols or something. At that time I am still asleep. So what can it be?

Yep, I am getting the same thing. Did anyone find out how to stop this ?

Found where the ipv6 message came from. It's produced by my crontab entry containing ntpdate.

I tried ntpdate with the -4 option (use only ipv4) but that didn't make a difference.

And it seems the ipv6 module is wrongly compiled with the following messages in the logs:

ipv6: Unknown symbol crypto_alloc_tfm
ipv6: Unknown symbol crypto_free_tfm
