在Linux环境下，具有FTP和部分Telnet功能的服务器源代码

################################################################################ # # # Super Ftp Server and Client for Wall-e # # # # SunMay30 2009 # # # ################################################################################ ////////\\\\\\\ ||Introduct || \\\\\\\\/////// Wall-e is a team for a project about two-demision code , for details at this:http://hi.baidu.com/hzau_wall_e this server and client programs is created for the s3c2410 platform board to conveniencely control it and fulfil files transferring at the same time , that is a simple combination for telnet and ftp server. Of course there are many fails and bugs in it , I'll appreciate the correction and criticism! ////////\\\\\\\ ||Functions || \\\\\\\\/////// 1 no count and no authentication , the shell running level result in who run the server in server side 2 basic ftp transferring functions as get files (g files ) and send files(s fname). 3 running common shells in client side(!cmd) and server side(cmd) 4 support multi-connections 5 error return: the server side will print error message in /var/log/wasd.log, and the client side will print these to stderr ////////\\\\\\\ || Usage || \\\\\\\\/////// 0 make the server and client change to this direction in console and run make [target] target: 1) null equal to all 2) all make server and client for both platform (arm and x86 linux) 3) host server (server_h) and client (client_h) for x86 linux 4) arm server (server_a) and client (client_a) for arm linux 5) hsac server (wasd) for x86 and client(was) for arm linux 6) ashc server (wasd) for arm and client (was) for x86 linux 7) best equals to ashc 8) you can change thest by edit Makefile 1 run the server and client server: ./server_x # x is for your platform h for host pc, a for arm, for details to see Makefile client: ./client_x xx.xx.xx.xx then you can operate in the client side. the prompt of client side will be: Walle> 2 run server side shells [usage] : cmd [return]: return what the shell will return to stdout and stderr .

E_SEND_ERR : send socket data err! case E_RPC_TIMEOUT : socket rpc timeout!(wait for sequential secs no data arrives ) case E_F_C_ERR : file create error! case E_REV_ERR : rev socket data error case E_BAD_SOCK_FD : default : unknown error! 6 bugs both side couldn't send control signal to each other, that is you can only send message that after a line break. so there are many shells programs couldn't be runned by client side(I'm really sorry for this): vi, ex,ed ,top ... running these progs will result in "RPC Timeout " errors after 5 secs, but the server and client will still work normally! 7 contact if you've any questions please send Email to me at supertiger@yahoo.cn or chat me by QQ : 547268476, I'll appreciate it !
