即使 CHAP 身份验证成功,我也无法连接到 PPTP VPN 服务器。
这是来自 /var/log/syslog:
Jun 11 07:27:22 aspire pppd[32221]: CHAP authentication succeeded
Jun 11 07:27:22 aspire pppd[32221]: LCP terminated by peer (MPPE required but cannot negotiate MPPE key length)
Jun 11 07:27:22 aspire pptp[32232]: nm-pptp-service-32219 log[pptp_read_some:pptp_ctrl.c:544]: read returned zero, peer has closed

我找到了答案,我必须在“高级设置”对话框中启用点对点加密(MPPE)。现在可以了。
