stochastic search primary menu skip to content eamonn travers umberto eco’s anti-library search for: apache2 , dns , linux , system administration part i: raspberry pi, dynamic dns, apache 2 (virtual hosts and reverse proxy) october 22, 2016 eamonn travers 1 comment in ersilia, to establish the relationships that sustain the city’s life, inhabitants stretch strings from the corner’s of the houses, white or black or gray or black-and-white according to whether they mark a relationship of blood, of trade, authority, agency. when the treads become so numerous that you can no longer pass among them, the inhabitants leave: the houses are dismantled. italo calvino “invisible cities” this article stems from a number private queries. the questions being mostly twofold: how to ensure that a private web server is reachable per dns (domain name system)? and can a private web server maintain more than one website? furthermore, these private queries came as a rule after raspbian , apache2 as well as any cloud or file sharing software had already been installed. raspberry pi are especially useful as private cloud or photo sharing application platforms. they’re cheap, silent and economical, while being relatively easy to install and maintain. web applications such as owncloud , nextcloud , picapport , piwigo , roundcude, dokuwiki and many others lend themselves naturally to raspbian . dynamic dns every machine in the internet has a public ip address. some are fixed and unchanging, others are changed intentionally in regular intervals. most private internet connections will be of the latter type (addresses which are changed at regular intervals). this is a problem. how to ensure that a private server is still reachable even though and despite of regular ip changes. the answer is dns or more precisely dynamic dns . there are a number of free dns providers (this article here describes a few) available. alternatively, most commercial web service providers also provide dynamic dns. so a decision has to be made, free or commercial dns provider and then there are still two questions open: firstly, how to (regularly) retrieve your public ip? secondly, how to inform your dns provider about any changes? retrieving your public ip address any external (external insofar as that the server is not within the lan ) website knows your public ip address. they have to if they wish to communicate with you. there are also servers whose soul purpose it is to communicate this public ip back to the requester. https://wtfismyip.com/ , https://api.ipify.org/ or http://checkip.dyndns.org/ to name just a few such servers. so retrieving the public ip isn’t a problem. now the only question is how to automate this request so that the public ip address can be retrieved in regular intervals. there are various possibilities: bash, perl, ruby, c#, python, javascript, jquery, nodejs to name but a few. here’s an example in bash #!/bin/bash ip=$(curl --silent 'https://api.ipify.org') echo $ip this code snippet will retrieve the public ip address. but it won’t inform the dns provider of any changes. regularly informing the dns provider of any changes each provider will have different ways of automatically updating a dns record. the web service provider strato serves here as an example. strato provides a dns update web page for it’s customers. the following example retrieves the public ip and sets two separate dns records for two different sites. both sites being housed on the same pi. #!/bin/bash # get the public ip address ip=$(curl --silent 'https://api.ipify.org') # which sites get should be reachable over this ip hosts="owncloud.travers-berlin.de dokuwiki.travers-berlin.de" # user credentials user="xxxxxxxxxxxx" pass="xxxxxxxxxxxx" # strato web page url="https://dyndns.strato.com/nic/update/nic/update" # now set the dns record for all websites. for host in ${hosts} do query="?system=dyndns&hostname=${host}&myip=${ip}" curl --ssl --user ${user}:${pass} ${url}${query} done this script must now run in regular intervals and this can be achieved using the linux scheduling daemon crond . the script has to be saved. the directory and name are arbitrary, something like /root/ipupdate.sh is more than sufficient. crond reads crontabs (cron tables) and executes the programs listed. the criteria for running are listed together with the program in the crontab. each user has his or her own crontab. to create a crontab for root, use the following command: pi :~ $ sudo crontab -e -u root and add the following table entry: 0.15,30,45 * * * * /root/ipupdate.sh this will ensure that ipupdate.sh will run every 15 min. system administration creating colorful bash output using the ansi color codes image may 25, 2015 eamonn travers 2 comments “even the simplest shepherd modestly watching his sheep under the stars would discover, once he understood the part he was playing, that he was more than a servant, was a sentinel. and each sentinel among men is responsible for the whole kingdom.” antoine de saint exupèry wind, sand and stars why bother? working with the shell is very satisfying. the closeness to the operating system which a shell allows offers a freedom which cannot be (in my opinion) replicated within a gui. the shell has many helpful features, auto command completion with tab, command history, shell shortcuts (eg. ctrl+e brings the cursor to the end of a line or ctrl+k cuts everything after the cursor to the clipboard) , to name but a few and one of these features is the ability to color the screen content. this feature can be used to personalize the shell on a user basis. e.g. red prompt for root, blue for user0, green for user1 etc. other possibilities include coloring warning banners such as /etc/issue or /etc/motd, making script messages standout (error messages colored red), coloring texts (like todo lists) and there is always just fooling around more for fun than effect. there are a lot of tutorials available on how to color bash output. some good, some bad. this article concerns itself with the 8 colors (not 8 bit 256 colors) which are available. the reasoning being simple, i don’t use them. how? firstly you need to know how to use ansi escape sequences. these escape sequences start (funnily enough) with the esc (ascii decimal 27 / hex 0x1b / octal 033 ) character, followed by two or more characters. a modern bash is quite capable of interpreting \033 (which is needed if 256 colors are to be used) but generally ansi/vt100 terminal codes are incorporated in scripts (\e being the escape code). if more than two characters follow, these are preceded by a left crotchet ([). the ansi color codes are grouped thus: text attribute code, text foreground color code, text background color code with each code separated by a semi-colon (;). the sequence is closed with the letter m. eg. \e[0;0m resets the shell and generally terminates any color changes that have be made. the text attribute codes are as follows: 0 : no attribute 1 : bold 4 : underscore 5 : blink 7 : reverse 8 : concealed the text foreground color codes are: 30 : black 31 : red 32 : green 33 : yellow 34 : blue 35 : magenta 36 : cyan 37 : white and finally the text background codes can be seen below : 40 : black 41 : red 42 : green 43 : yellow 44 : blue 45 : magenta 46 : cyan 47 : white as you can see the second character (1..7) defines the color, while the first character (3|4) denotes text or background color. here are a few examples to help clarify. colorful prompt: edit ~/.bashrc and add the following variable ps1=’\e[1;32m[\u@\h \w]\$\e[0;0m ‘ the command $ source .bashrc makes the changes visible. in this case a bold green prompt containing the login, host and working directory, surrounded by crotchets and followed by a dollar sign. [user@host ~]$ echo -e this short script will run through the colors on the prompt. there are many, many similar such scripts to be found all over the web. this example is quick and dirty and can be typed directl
