network is unreachable为什么会这样? help

sgx 2003-08-03 08:33:29
由于需要将邮件服务器的ip地址改为:210.83.*.*
(邮件服务器:redhat7.2 + sendmail + openwebmail 原来的ip是172.16.*.*)
用netconf 将IP改过来以后。重新启动计算机。用ifconfig发现ip地址已经改过来了。 ping 127.0.0.1 可一ping 通.ping 网关ping 不通
出现: network is unreachable 提示;
关闭计算机时出现: stopping squid failed

请问这是为什么???

thanks

to seagao(seagao) ,fierygnu(va_list) 你们刚开始学习路由吧,这里还没由到和路由由关系的时候,首先要由网络接口才可以谈到路由,目前的 network is unreachable 错误提示的就是网卡都没有有效使用的信息。记住了。
你们可以简单的做个测试(如果你们的系统支持的话)2000的系统你可以把网线把了,然后发现网卡的图表多了一个差,这个时候你 ping 除了 127。0。0。1 的网内地址看看,错误就是这个,然后你们自己分析看看和路由由关系吗? :)

新的ip地址和旧的ip地址是在一个网段内吗,他们是不是同一个网关呀,
先试试,新ip到同一个网段内的主机通不通
在分析一下你的路由表了,看看路由策略.

netstat -r看看路由。应该是没有路由。你的网关地址是什么?

建议重新设置 ip,把ifconfig命令写到 rc.local中

但是IP地址我用netconf已经设置完了呀
为什么还会出现这样的错误呢??

没有指定ip地址所以出现 network is unreachable 。
因为没有正确的网络配置,所以 squid 在启动的时候一直在 DNS test,但是总是不能成功
所以可能导致 stop 不了。
你重新设置 ip,可以把ifconfig命令写到 rc.local中,可以保证ip不会被改回来。
go语言系统编程,是英文版, What this book covers Chapter 1, Getting started with Go and Unix Systems Programming, starts by defining what systems programming is before talking about the advantages and the disadvantages of Go, the features of Go version 1.8, two handy Go tools named gofmt and godoc, as well as the various states of Unix processes. Chapter 2, Writing Programs in Go, helps you learn how to compile Go code and how to use the environment variables that Go supports, and understand how Go reads the command line arguments of a program. Then, we will talk about getting user input and output, which are fundamental tasks, show you how to define functions in Go, where the defer keyword is mentioned for the first time in this book and continue by discussing the data structures that Go offers using handy code examples. In the remaining sections of the chapter, we will discuss Go interfaces and random number generation. I am sure that you are going to enjoy this chapter! Chapter 3, Advanced Go Features, goes deeper and starts talking about some advanced Go features, including error handling, which is critical when developing systems software and error logging. Then it introduces you to pattern matching and regular expressions, Go Reflection, and talks about unsafe code. After that, it compares Go to other programming languages and presents two utilities, named dtrace(1) and strace(1), that allow you to see what happens behind the scenes when you execute a program. Lastly, it talks about how you can use the go tool to detect unreachable code and how to avoid some common Go mistakes. Chapter 4, Go Packages, Algorithms, and Data Structures, talks about algorithms and sorting in Go and about the sort.Slice() function, which requires Go version 1.8 or newer. Then it shows Go implementations of a linked list, a binary tree and a hash table. After that, it discusses Go packages and teaches you how to create and use your own Go packages. The last part of the chapter discusses Garbage collection in Go. Chapter 5, Files and Directories, is the first chapter of this book that deals with a systems programming topic, which is the handling of files, symbolic links, and directories. In this chapter, you will find Go implementations of the core functionality of Unix tools such as which(1), pwd(1), and find(1), but first you will learn how to use the flag package in order to parse the command-line arguments and options of a Go program. Additionally, you will learn how to delete, rename, and move files as well as how to traverse directory structures the Go way. The last part of this chapter implements a utility that creates a copy of all the directories of a directory structure! Chapter 6, File Input and Output, shows you how to read the contents of a file, how to change them, and how to write your own data to files! In this chapter, you will learn about the io package, the io.Writer and io.Reader interfaces, and the bufio package that is used for buffered input and output. You will also create Go versions of the cp(1), wc(1), and dd(1) utilities. Lastly, you will learn about sparse files, how to create sparse files in Go, how to read and write records from files, and how to lock files in Go. Chapter 7, Working with System Files, teaches you how to deal with Unix system files, which includes writing data to Unix log files, appending data to existing files, and altering the data of text files. In this chapter, you will also learn about the log and log/syslog standard Go packages, about Unix file permissions, and take your pattern matching and regular expressions knowledge even further using practical examples. You will also learn about finding the user ID of a user as well as the Unix groups a user belongs to. Lastly, you will discover how to work with dates and times in Go using the time package and how to create and rotate log files on your own. Chapter 8, Processes and Signals, begins by discussing the handling of Unix signals in Go with the help of the os/signal package by presenting three Go programs. Then it shows a Go program that can rotate its log files using signals and signal handling and another Go program that uses signals to present the progress of a file copy operation. This chapter will also teach you how to plot data in Go and how to implement Unix pipes in Go. Then it will implement the cat(1) utility in Go before briefly presenting the Go code of a Unix socket client. The last section of the chapter quickly discusses how you can program a Unix shell in Go. Chapter 9, Goroutines – Basic Features, discusses a very important Go topic, which is goroutines, by talking about how you can create goroutines and how you can synchronize them and wait for them to finish before ending a program. Then it talks about channels and pipelines, which help goroutines communicate and exchange data in a safe way. The last part of the chapter presents a version of the wc(1) utility that is implemented using goroutines. However, as goroutines is a big subject, the next chapter will continue talking about them. Chapter 10, Goroutines – Advanced Features, talks about more advanced topics related to goroutines and channels, including buffered channels, signal channels, nil channels, channels of channels, timeouts, and the select keyword. Then it discusses issues related to shared memory and mutexes before presenting two more Go versions of the wc(1) utility that use channels and shared memory. Lastly, this chapter will talk about race conditions and the GOMAXPROCS environment variable. Chapter 11, Writing Web Applications in Go, talks about developing web applications and web servers and clients in Go. Additionally, it talks about communicating with MongoDB and MySQL databases using Go code. Then, it illustrates how to use the html/template package, which is part of the Go standard library and allows you to generate HTML output using Go HTML template files. Lastly, it talks about reading and writing JSON data before presenting a utility that reads a number of web pages and returns the number of times a given keyword was found in those web pages. Chapter 12, Network Programming, discusses topics related to TCP/IP and its protocols using the net Go standard package. It shows you how to create TCP and UDP clients and servers, how to perform various types of DNS lookups, and how to use Wireshark to inspect network traffic. Additionally, it talks about developing RPC clients and servers in Go as well as developing a Unix socket server and a Unix socket client. As you will see, at the end of each chapter there are some exercises for you to do in order to gain more information about important Go packages and write your own Go programs. Please, try to do all the exercises of this book
