在gentoo-2.6.10-r3 下用telnet的问题
各位大侠：小弟在gentoo-2.6.10-r3 下 用 telnet , 发现一个奇怪的问题: 只有telnet 127.0.0.1 行，telnet 本机的ip无论在本机和其它机子都不行，但ping本机的ip没问题，情况如下：
gentoo / # telnet 192.168.1.102
Trying 192.168.1.102...
Connected to 192.168.1.102.
Escape character is '^]'.
Connection closed by foreign host.
gentoo / # telnet 127.0.0.1
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
gentoo login: xxx
Password:
ip的配置：
gentoo / # ifconfig
eth0 Link encap:EthernetHWaddr 00:0A:E4:55:C8:F2
inet addr:192.168.1.102Bcast:192.168.1.255Mask:255.255.255.0

不知道那里没有配置好，PTY 已设，防火墙没设，问题出在那里，各位能给些建议吗？谢谢！
