modprobe error

This is probably dumb but I'm not so up to speed with kernel modules.

daemon.log keeps on giving me this:
Oct 24 13:54:27 korona 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)

I havent knowingly installed ipv6, although I did install the kernel modules... ANy easy method to switch this off?

thanks

The reason you are seing this is due to the kernel being compiled without crypto support and thus misses the symbols crypto_alloc_tfm and crypto_free_tfm.

Then some aplication, most likely udev(?) tries to load the ipv6 module that requires these symbols generating the log messages you see.

Two possible solutions might be available, if one will make these warinings go away. Either one has to recompile the kernel and add crypto support. Or simply remove the ipv6 modules and do a depmod -a and it should go away.

Sorry to ask a stupid question: how do I remove the module?

as I mentioned, kernels really aren;t my thing

rm -f /lib/modules/2.6.16.16/kernel/net/ipv6
depmod -a

does the trick. Better is to keep a copy of this directory tucked away somewhere.

I checked with the ntpdate command (which triggers the ipv6 module as well). Works like a charm and no annoying messages anymore.

Thanks Tor,

Albert

P.S. I assumed you have root access.
