there is some problems when i want to reinstall apache2 through aptitude / package. when i try usual apt-get remove apache2 then apt-get install apache2 i always get this message
/etc/apache2/envvars: No such file or directory
invoke-rc.d: initscript apache2, action “start” failed.
the message then says that its probably because you have deleted dir apache2. the problem is on apache2.2-common, but simple apt-get remove or dpkg –purge wont work, mostly because thera still package dependencies that prevent the package from deletion. after googling sometime i find same post that has been solved by running this command :
internet end-user or we can refer to common user normally doesn’t care about how internet works. what they really want is just internet access. what they now consider maybe just speed of their internet connection and amount data transfer quota they have. but sometime knowledge about how internet works is needed. for example to explain view questions about how to check whether or not out connection work, how to solve our miss-configuration settings, etc.
Internet model can serve as guide to answer these questions. internet model comes up with protocol classification. once you know where your need is in the internet model, it will be easier for you to determine the problem and solve or at least know why the problem happened.
these are how internet models map their protocols. there are 2 internet models, OSI and TCP/IP. what we use today is actually TCP/IP model, but OSI model can somewhat help us to understand the ideal internet model.
Wireshark Cookie Dump OKCancel fills my email and chatting form. At first i thought it is wireshark application that generate it. But after i google, i found that it is caused by the cookie injector (greasemonkey), so if u find some problem, just disable the grease monkey or disable its cookie injector script.
