网络——可ping,却不可telnet

最近我的QNX主机可以被我的WinXP主机ping上,但是telnet却怎么也不成功,而且好像还是主机强制停止的,不知道为什么!请高手指教!

从我的WinXP主机上可以正常telnet到另一台QNX主机,所以可以确定故障点在这台QNX主机上。在连接这台QNX主机的信息:

ping的成功信息:
Pinging 192.168.0.101 with 32 bytes of data:
Reply from 192.168.0.101: bytes=32 time<1ms TTL=255

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

telnet后的信息:
正在连接到192.168.0.101…不能打开到主机的连接,在端口23:连接失败

用CuteFTP与之相连,立即弹出对话框显示信息:
The server forcibly closed the connection.
This normally results from a loss of the connection due to a timeout or a server reboot.
1)Please try connecting to the server again later.
2)You may verify that the problem is not local by trying to connect to an alternate server.

大体意思就是说QNX主机强制关闭了连接,而且在操作中是立即弹出来的,反映了QNX主机是“有目的、有意识”的行为,可能是说明我的主机网络上什么配置出了问题,但是本人才疏学浅,只能分析到这里了,望QNX的高手伸手相助,在下感激不尽!

是因为telnet服务没有打开。

修改/etc/inetd.conf,启动inetd,就可以了。
