在   Miscellaneous Utilities ---> 
[ ] taskset 
将其前的星号去掉即可。 错误2： networking/interface.c:818:error: `ARPHRD_INFINIBAND'' undeclared here (not in a function)
networking/interface.c:818: error: initializer element is not constant
networking/interface.c:818: error: (near initialization for `ib_hwtype.type'')
make[1]: *** [networking/interface.o] Error 1
make: *** [networking] Error 2 解决办法: networking/interface.c中添加
#define ARPHRD_INFINIBAND 32   /* InfiniBand */ 错误3： 找不到mkcramfs
解决办法：
aptitude install cramfsprogs -------------------------------------------------- 在arm中查看telnetd服务是否开启办法：
＃netstat -ant 
显示没有telnetd，则telnetd服务没有开启
