Do you have anything in /etc/modprobe.conf or /etc/modprobe.d that interacts with the crypto modules? Not really. I haven't modified /etc/modprobe* for ages, they are all stock.
[superuser@shark :: ~]grep crypt /etc/modprobe.d/* /etc/modprobe.d/ipw2200:options ipw2200 hwcrypto=0 led=1 [superuser@shark :: ~]grep crypt /etc/modprobe.conf* [superuser@shark :: ~] Thanks for your 'lsmod' output, I found that if I manually load arc4, ecb, sha1_generic and crypto_blkcipher first, then manual ppp_mppe insertion works. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
