Since few months I've switched my old BLU r1 HD Phone (a great old low budget phone for its price) to a friend's iPhone 10 ( X ) who gifted it for me. Coming from Android world, everyone who has experience with it is a pain in the ass as some of the Apps, which are into Google's play store does not have the same equivalent into Apple's install Package manager tool AppStore. Some of the crucial tools which I was interested as a freshly new migrated user from Android to iPhone was to have a decent SSH / Telnet client and Terminal, with which I can easily connect to my Linux servers both home and work.
As Android Phone user, to connect and manage my SSH sessions I used most often some of the most popular Connectbot / SSHDroid / JuiceSSH.
On Android I've usually installed all of these tools but most frequently used Connectbot, which quickly become my favourite SSH client for Android over time.
The reasons why I really loved Connectbot and used it on Android OS in short:
- It is Completely free
- Ad-free
- Open-source (too bad not Free software but still step better)
- Copy and paste text between Applications
- Customizable interface (i.e. font size, keyboard layout, SSH auth agent, etc.)
I've seen some people used and preferred Termius but never myself really liked this client, as it was including some Advertisements or for don't remember why reason.
Switching to iOS mobile operating system, of course was quite a shock especially the moment I found out the standard loved SSH Remote Client programs are used are not available or have only a paid version. Thus it took me quite a while of a research and googling until I found some decent stuff.
Tried for a time with Termius as well but again, its Ads and lack of some functionality pissed me off, so I've moved on to Shelly.
Shelly is really not a bad tool but has limitation over the SSH sessions you can add and other limitations, which can only be unlocked with an "Upgrade", to its paid version, thus I decided after few weeks of attempts to make it my remote server management mobile tool for iPhone, I've dropped it off as well.
Then I found the Blink Shell App – Blink Shell is a professional, desktop grade terminal for iOS. As overall the tool is really great and is easy to use but again to have it used in its full power you need the paid version and until you pay for it every now and then you got interruption of your shell for some really annoying ads.
Thus even though I used it for a times this few tools with whom basicly you can do basic remote ssh / telnet session operations eventually, started looking for a better SSH Client Free alternative for iPhone Users.
Then came a friend at home for a dinner my dear friend Milen (Static) and he show me iOS.
The moment I saw this tool I totally loved it, for its simplicity and its resemblance to a classical TTY Physical old Linux console I used back in the days and its ability to resemble easily any improved functionaltiy through simple screen (multiple session management) command tool or tmux.
Wait, what's iSH ? And why it is the Best SSH / Telnet client to manage your servers remotely on iOS Mobiles (iPhone and IPads) ?
iSH is a project to get a Linux shell environment running locally on your iOS device, using a usermode x86 emulator.
In other wors iSH is Linux emulator with busybox and a package ports for many of the standard Linux tools you get by simple apt-get / yum or if I have to compare you get via the MobaXterm's advanced apt-cyg (Cygwin packages) tool capabilities.
Once iSH is installed it comes with pre-installed apk command line package management tool, with which you can install stuff like openssh-client / screen / tmux / mc (midnight commander) etc. apk, is an apt like command like tool which uses as a basis for installing its packages Alpine Linux repositories.
Alpine Linux is perhaps little known as it is not one of these main stream disributions, such as Fedora or Ubuntu, but for those more concerned about security Alpine Linux is well known as it is a security-oriented, lightweight Linux distribution based on musl libc and busybox. What makes the Linux even more attractive and perhaps the reason why the iSH developers decided to use it as a basis for their iSH emulator is it being actively developed and its tightened security makes it a good compliment to the quite closed and security focused mobile platform iOS.
iSH is available straight from AppStore , so to use it install it and run it (it is really a great news that iOS does not require iphone to be jailbreak – ed, and it is an ordinary installable software straight from AppStore):
iSH, already comes with some of the standard programs you would expect in a Linux environment such as Vi, wget, zip / unzip, and tar.
However to fit it better for my use over ssh and improve its capabilities, as well as support and use multiple Virtual windows ssh, just like you do on a Linux xterm
run from ish shell:
# apk add openssh-client
# apk add screen
# apk add vim
# apk add mc
I also like to have a Midnight Commander and VIM Text editor installed out of the box to be able to move around in Ncurses interface through my iPhone.
Note that, just like most GNU / Linux distributions, iOS shell will run a normal bash shell.
From there on to use iSH as my default SSH client and enable my just installed GNU screen some Windowing beauty for readability whence I use the screen with multiple ssh logins to different servers as well make the screen Virtual consoles to have ability for scroll back and scroll up of console text to work, I do set up the following .screenrc inside my /home/iPhoneuser
The .screenrc to setup on the iSH to easify your work with screen is as follows:
# An alternative hardstatus to display a bar at the bottom listing the
# windownames and highlighting the current windowname in blue. (This is only
# enabled if there is no hardstatus setting for your terminal)
hardstatus on
hardstatus alwayslastline
hardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y} %m/%d %C%a "
# Enable scrolling fix the annoying screen scrolling problem
termcapinfo xterm* ti@:te@
# Scroll up
bindkey -d "^[[5S" eval copy "stuff 5\025"
bindkey -m "^[[5S" stuff 5\025# Scroll down
bindkey -d "^[[5T" eval copy "stuff 5\004"
bindkey -m "^[[5T" stuff 5\004# Scroll up more
bindkey -d "^[[25S" eval copy "stuff \025"
bindkey -m "^[[25S" stuff \025# Scroll down more
bindkey -d "^[[25T" eval copy "stuff \004"
bindkey -m "^[[25T" stuff \004
You can download the same .screenrc file from here straight with wget from the console:
# wget https://www.pc-freak.net/files/.screenrc
Run GNU screen manager
# screen
You will end up with a screen session, to open a new session for Virtual Terminal use virtual keyboard from ISH and Press
CTRL + A + C
To open other Virtual Windows inside screen just press CTRL + A + C as many times as you need it, each session will appear ina small window on the down corner as you can see in screenshot
To move across the Screen unnamed 3 Virtual Windows 0 ash 1 ash and 2 ash use the Virtual keyboard
for next WIndow use key combination:
CTRL + A + N (where + is just to indicate you have to press them once after another and not actually press the + 🙂 )
For Previous Window use:
CTRL + A + P
Or use CTRL + A and type
:number 3 (where number is the number of window)
The available iSH commands without adding any further packages which are part of the busybox install are as follows:
Available /bin/ directory commands:
arch ash base64 bbconfig busybox cat chgrp chmod chown conspy cp date dd df dmesg dnsdomainname dumpkmap echo ed egrep false fatattr fdflush fgrep fsync getopt grep gunzip gzip hostname ionice iostat ipcalc kbd_mode kill link linux32 linux64 ln login ls lzop makemime mkdir mknod mktemp more mount mountpoint mpstat mv netstat nice pidof ping ping6 pipe_progress printenv ps pwd reformime rev rm rmdir run-parts sed setpriv setserial sh sleep stty su sync tar touch true umount uname usleep watch zcat

If you're a maniac developer you can even use iSH, to do some programs development with vim with Python / Perl or PHP as these are available from the Alpine repositories and installable via a simple apk add packagename for security experts nmap and some security tools are also available but unfortunately not everything is still working as this project is in active development and iOS has some security limitations if OS is not ROOTED 🙂
Hence some of the packages you can install via apk manager will be failing actually.
There is a list of What works and what doesn't still on iSH on the project github wiki check it out here.
There is much more funny stuff you can do with it, and actually my quick research on how people use iSH on their phones lead me to some Videos talking about iOS and Ethical hacking etc, but I'll stop here as I dont have the time to dig deeper to it.
If you know or have some good use of iSH or some other goody you are using as a hack please share in comments.
Enjoy ! 🙂
How to show country flag, web browser type and Operating System in WordPress Comments
Wednesday, February 15th, 2012!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,
!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!
I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":
Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;
1. Download and unzip Comments Info Detector
linux:/var/www/blog:# cd wp-content/pluginslinux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...
Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector
To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)After having enabled the plugin as a last 3rd step it has to be configured.
3. Configure comment-info-detector wp plugin
By default the plugin is disabled. To change it to enabled (configure it) by navigating to:
Settings -> Comments Info DetectorNext a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:
Display Country Flags Automatically (Change No to Yes)Display Web Browsers and OS Automatically (Change No to Yes
After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂
