所以呢,我们可以根据抓到的包的TTL推测对端OS的类型。 这应该是个类unix操作系统呢 3 handshake 这应该是个windows操作系统呢 Usage 2、判断抓包在哪一端 比如,给你一个包含http请求和响应的抓包文件。你使用wireshark打开,你如何确定该文件是从http client端抓取,还是从http server端抓取的呢?
As Phoenix mentioned the default TTL value is based on OS and Protocol. For example, BGP has a default TTL value of only 1 (and that is why the additional configuration is required when neighbors are not directly connected). Traceroute keeps on increasing the TTL value. HTH, Anna Expand...

I just want to add to your very valuable information, as you said the TTL is all about the destination and has nothing to do with the source, different OS has different TTL (considered as an aspect of the OS fingerprinting): Windows: 128 Linux: 64 Cisco: 255 Solaris: 255 below are pi...
Mac OS X下,使用javaagent,可能会报JavaLaunchHelper的出错信息。 JDK Bug:http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8021205 可以换一个版本的JDK。我的开发机上1.7.0_40有这个问题,1.6.0_51、1.7.0_45可以运行。 #1.7.0_45还是有JavaLaunchHelper的出错信息,但不影响运行。
In KeeneticOS 3.7 and higher, to change the TTL parameter of all packets for incoming connections, use the command: interface {name} ip adjust-ttl recv {ttl} {ttl} — the value of the TTL change. Can take values from 1 to 255 inclusive. ...
用TTL电平串口线访问嵌入式系统 家庭宽带网关为家庭用户提供了宽带上网、IPTV和电话业务。然而，在使用中用户会遇到各种问题，需要使用管理账号和密码进行设置。虽然，现在的安装过程很简单，全部是通过下发配置即可完成，但是，下发的配置不一定满足具体特定用户的需要。如果需要自己定制或维修工上门检测，都需要使用管理...

Decrementing TTL values can indicate the approximate number of hops a packet has traversed. This helps trace the origin of traffic and geolocate hosts. Configuring TTL The default TTL value can be configured on an OS and network device:
OS is running the program, starting from main() True or False? The loading of the program into the memory is done eagerly (all at once) False. It was true in the past but today's operating systems perform lazy loading, which means only the relevant pieces required for the process to ...
