Hi Friends, I am using CentOS-6.8 and ppp-2.4.5 , rp-pppoe-3.10-16. I am getting CHAP Authentication failed when do the following ifup ppp0 ifdown ppp0 sleep 20; ifup ppp0 The same line working fine if I wait 2 minutes to bring it up after shutdown the line. I did not see kind of issue on CentOS-5.11 . Please let me know if I need to change any config parameters. Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
