工作学习 / IT技术讨论 / 2个网络的怪问题1、一台服务器，如果PING，一点问题没有，很快，从TELNET过去开始，到出现LOGIN，要很长时间（大概5-10分钟），但出现LOGIN后又正常了
2、另外一台，PING也是好的，但如果用FTP传文件，传到一部分后，就停止了，进程还在，但数据传输好象几乎停止了，尝试用RCP或者UUCP都一样。
注：以上服务器都是LINUX系统

can't figure out anything form you post, butyou can download a software called "ethreal" from gnu and intercept the packet form the network, you will be easy to figure out what happen

enable dns or edit /etc/host file.

不觉得这两个文件有问题啊，站点地址都在HOSTS文件里面

bear in mind, telnetd is trying reverse name lookup.

make sure you using hosts before dns if you don't have dns setup correctly. (e.g nsswitch.conf)

this could help...This sounds like a reverse DNS lookup. Make entries in '/etc/hosts' for each machine. You should also have the line "order hosts, bind" in '/etc/host.conf' .
check ifconfig for the info about RX errors and TX overruns, if they have large number of error, that could be a symptom of poor interrupt handling in the kernel of hardware.
try use another NIC, see if the speed is improved...
