| 端口到底是什么啊，是不是端口都是有亏定的啊，我常常看靠80，1080，21，7626等等，是不是只有那么多，还是随便几个数字都是端口（即随意定出来的）不同的端口有什么不同啊，如果有这个专题的文章的，麻烦告诉我地址，或是发到lwa82@sina.com |

TCP/IP通信时需要知道对方的hostname和port,同时也提供自己 的hostname和port,还要指明protocol.其中port就是你说的端口. 这五样东西构成一个通信关联. 主机会在每一个提供服务的端口上运行一个daemon程序,监听来自别的机器的对 这个端口的服务请求,并根据相应的protocol完成服务.一般每一个端口提供一种服务. 这里所说的端口不是PC机上的那种硬件I/O端口,而是一种软件形式上的端口概念. 23是telnet服务的约定端口号. 21是ftp服务的端口号. 80是http的端口号. tcpmux 1/tcp # rfc-1078 echo 7/tcp echo 7/udp discard 9/tcp sink null discard 9/udp sink null systat 11/tcp users daytime 13/tcp daytime 13/udp netstat 15/tcp qotd 17/tcp quote chargen 19/tcp ttytst source chargen 19/udp ttytst source ftp-data 20/tcp ftp 21/tcp telnet 23/tcp smtp 25/tcp mail time 37/tcp timserver time 37/udp timserver rlp 39/udp resource # resource location name 42/udp nameserver whois 43/tcp nicname # usually to sri-nic domain 53/tcp domain 53/udp mtp 57/tcp # deprecated bootps 67/udp # bootp server bootpc 68/udp # bootp client tftp 69/udp gopher 70/tcp # gopher server rje 77/tcp finger 79/tcp http 80/tcp # www is used by some broken www 80/tcp # progs, http is more correct link 87/tcp ttylink kerberos 88/udp kdc # Kerberos authentication--udp kerberos 88/tcp kdc # Kerberos authentication--tcp supdup 95/tcp # BSD supdupd(8) hostnames 101/tcp hostname # usually to sri-nic iso-tsap 102/tcp x400 103/tcp # ISO Mail x400-snd 104/tcp csnet-ns 105/tcp pop-2 109/tcp # PostOffice V.2 pop-3 110/tcp # PostOffice V.3 pop 110/tcp # PostOffice V.3 sunrpc 111/tcp sunrpc 111/tcp portmapper # RPC 4.0 portmapper UDP auth 113/tcp ident # User Verification sftp 115/tcp uucp-path 117/tcp nntp 119/tcp usenet # Network News Transfer ntp 123/tcp # Network Time Protocol ntp 123/udp # Network Time Protocol netbios-ns 137/tcp nbns netbios-ns 137/udp nbns netbios-dgm 138/tcp nbdgm netbios-dgm 138/udp nbdgm netbios-ssn 139/tcp nbssn imap 143/tcp # imap network mail protocol NeWS 144/tcp news # Window System snmp 161/udp snmp-trap 162/udp exec 512/tcp # BSD rexecd(8) biff 512/udp comsat login 513/tcp # BSD rlogind(8) who 513/udp whod # BSD rwhod(8) shell 514/tcp cmd # BSD rshd(8) syslog 514/udp # BSD syslogd(8) printer 515/tcp spooler # BSD lpd(8) talk 517/udp # BSD talkd(8) ntalk 518/udp # SunOS talkd(8) efs 520/tcp # for LucasFilm route 520/udp router routed # 521/udp too timed 525/udp timeserver tempo 526/tcp newdate courier 530/tcp rpc # experimental conference 531/tcp chat netnews 532/tcp readnews netwall 533/udp # -for emergency broadcasts uucp 540/tcp uucpd # BSD uucpd(8) UUCP service klogin 543/tcp # Kerberos authenticated rlogin kshell 544/tcp cmd # and remote shell new-rwho 550/udp new-who # experimental remotefs 556/tcp rfs_server rfs # Brunhoff remote filesystem rmonitor 560/udp rmonitord # experimental monitor 561/udp # experimental pcserver 600/tcp # ECD Integrated PC board srvr mount 635/udp # NFS Mount Service pcnfs 640/udp # PC-NFS DOS Authentication bwnfs 650/udp # BW-NFS DOS Authentication kerberos-adm 749/tcp # Kerberos 5 admin/changepw kerberos-adm 749/udp # Kerberos 5 admin/changepw kerberos-sec 750/udp # Kerberos authentication--udp kerberos_master 751/udp # Kerberos authentication kerberos_master 751/tcp # Kerberos authentication krb5_prop 754/tcp # Kerberos slave propagation listen 1025/tcp listener RFS remote_file_sharing nterm 1026/tcp remote_login network_terminal kpop 1109/tcp # Pop with Kerberos ingreslock 1524/tcp tnet 1600/tcp # transputer net daemon cfinger 2003/tcp # GNU finger nfs 2049/udp # NFS File Service eklogin 2105/tcp # Kerberos encrypted rlogin krb524 4444/tcp # Kerberos 5 to 4 ticket xlator canna 5680/tcp # Japanese CANNA Server wnn6 22273/tcp # Japanese Wnn Server irc 6667/tcp # Internet Relay Chat dos 7000/tcp msdos |
