请教boa，telnet的问题

自己建立的文件系统 系统的打印信息如下
用其他电脑访问boa和用telnet登录都没反应，是什么原因？还需要什么信息？
多谢了！

你的boa没有运行，
telnet这样看不出来。

建议详细看一下手册。

应该是devpts的问题，请帮忙确认。

boa是运行起来的“gethostbyname:: Success”

请版主看一下，我已发文件系统和内核给你了，请你运行看看。

mount: mounting devpts on /dev/pts failed: No such file or directory
mknod: /dev/pts/0: Operation not permitted
ln: /dev/fb0: File exists
ln: /dev/tty1: File exists
mount: mounting none on /proc failed: Device or resource busy
gethostbyname:: Success

我用了几个小时把你做的文件系统里面文件挨个挨个的读了，然后挨个挨个的对比了：
首先，你没有建立mdev.conf文件，这个在移植手册里特意说明了的；
第二，你的boa.conf文件配置有问题，请自行参考用户手册移植方法；
boa是运行起来的“gethostbyname:: Success”
这句话就是因为你配置的问题。
第三，你移植的boa程序有问题，用你移植的那个根本跑不起来。
所以，我说的那句建议你详细看一下手册是没有说错的。

我用你给我的文件系统，修改了boa.conf文件，建立了mdev.conf文件，修改了boa，然后就OK了。

版主的态度和精神我很感动。
根据你的指点我可以运行boa了。

多谢！

昨晚研究了一下telnet，确认了linux2.6.25.8是默认支持devpts的。
我原先是将netd添加到目标板的etc/init.d，昨晚改为放到etc/下，inittab也是正确的：
# System initialization.
::sysinit:/etc/init.d/rcS
s3c2410_serial0::askfirst:-/bin/sh
::once:/usr/sbin/telnetd -l /bin/login
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
[root@EmbedSky /]#
但是不出现登录对话框，请问版主还需要什么定位信息？

现个人认为是因为建立节点 mknod /dev/pts/0 c 136 0错误导致telnet不可用。


启动信息和rcS等文件如下：

我在原手册上修改了fatab文件
mdev  /dev  tmpfs default 0 0
解决了mount -t devpts devpts /dev/pts失败的问题。

D:/telnetfail.JPG

telnet有没有什么调试手段?
手册上t添加文件系统，添加etc下的文件有说道的servers，这是不是笔误，应该是services吧？

问题解决了。
是我在配置开发板ip之前调用了netd，因此telnet会失败。
但是boa却可以正常运行。
我把运行netd放到配置ip命令之后就可以了。
非常感谢版主的支持！

我最近也遇到了和楼主一样的问题：“gethostbyname:: Success”，曾经搜到楼主的这个帖子，但是这个帖子没有说明具体的解决方法。后来我查了很多资料，总算找到了解决方法，希望后来遇到这个问题的朋友可以顺利解决，不用向我一样浪费了一天时间。解决方法我在我的博客里说明了，需要的朋友可以看一下。http://hi.baidu.com/%C4%CF%B9%AC%BE%F8%B7%E5/blog/item/e0020fcdeeaae1367e3e6f7f.html
（解决方法在常见错误 6 中给出）
