请教:建拨号服务器时拨入方一直提示占线(mgetty.log.ttyS0)

speedwolf

按照网上建拨号服务器的方法,建好验证时老是说占线.
自己用WHO和IFCONFIG检查不出拨入信息.
怀疑是MGETTY出现问题,但是自己看不懂日志文件.
现在有两个日志文件,请大家指教
以下是日志文件:
mgetty.log.ttyS0:

本人的猫是TTYS0....
用MINICOM测试了....

贴个配置吧。我做拨号服务器没遇到过这个问题。你用的是什么系统呀？

speedwolf

redhat9.0,
在红旗4.0下也没有成功.

speedwolf

/etc/inittab下加
s1:1235:respawn:/sbin/mgetty -D -s 38400 ttyS0

编辑/etc/ppp/options文件，在其中加入：
-detach
crtscts
netmask 255.255.255.0
asyncmap 0
proxyarp

编辑/etc/ppp/options.ttyS0
加入192.168.0.2:192.168.0.100    (2为本机,100为拨入机)

编辑/etc/ppp/pap-secrets文件，在该文件中设置如下：
192.168.0.100 192.168.0.2 "" 192.168.0.100

建立pcguest拨号用户帐号，创建登录Shell  为/etc/ppp/ppplogin
#! /bin/sh
/usr/sbin/pppd auth -chap +pap login 192.168.0.2:192.168.0.100

将该文件置为可执行模式： chmod 755 ppplogin；
pppd默认只能由root用户执行，为了使普通用户能够执行pppd，需要运行命令：#chmod u+s /usr/sbin/pppd。

在/etc/shells文件中加进一句话：/etc/ppp/ppplogin

启用IP转发功能，修改文件/etc/sysctl.conf将 net.ipv4.ip_forward = 0 改为net.ipv4.ip_forward=1 ，保存退出。重启Linux服务器
