Passwordless SSH Login between OS X and Remote Server

terminal-iconIf you commonly ssh from your OS X computer to a remote server such as a web server it makes sense to set up passwordless ssh login so you can have a secure connection without having to always enter your password. Setting up passwordless login also allows you to run automated scripts to help with managing things like offsite backups. Scripts can’t be automated if they require someone to be present at your machine typing in passwords every time they run.

It’s worth noting that you may first want to check if you already have¬†existing ssh keys on your computer. This can be done by entering¬†cd ~/.ssh [enter] at your terminal. If you get a response back stating “No such file or directory” then you need to proceed with the following steps.

To set up passwordless login between a remote unix/linux server and your OS X machine fire up terminal and…

1. generate an RSA private key

ssh-keygen -t rsa -C “”

2. copy the key to your clipboard

pbcopy < ~/.ssh/

3. ssh into the webserver

ssh (login with your password for the last time)

4. make a .ssh directory, if it doesn’t already exist

mkdir .ssh

5. create an authorized_keys file and paste in the key from mac that you just copied to your clipboard

vi .ssh/authorized_keys (paste in key from clipboard, save)

6. set permissions for necessary files and directories on webserver

chmod go-w ~
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

That’s all there is to it. These steps could all be combined into a single line but the above is much easier to follow.

Resolving ‘Bad Request Error 400’ in Gmail on Chrome

Gmail on Chrome: Bad Request Error 400
Gmail on Chrome: How to resolve the Bad Request Error 400

I periodically come across the “Bad Request Error 400” problem when using Gmail on Google Chrome. I’m not the only one as you can see from a Google search on the topic. One minute all is well and the next, reload after reload all you see is a blank page and this error message. You haven’t changed anything but things just don’t work anymore. If you try accessing Gmail on a different browser like Firefox, everything seems good, so it’s not Gmail itself; it’s the combination of Gmail and Chrome.

It seems quite ridiculous really that this issue should happen on Chrome. Shouldn’t Gmail on Chrome be essentially bulletproof? Google on Google. C’mon.

When looking for answers the most common suggestion you’ll find is to clear all of your browsing data; history, cache, cookies, etc. I happen to like my browsing data. Among other things, it helps me find things and allows me to stay logged in on various sites. Deleting it all causes me pain.

After searching through various sites and the Gmail and Chrome forums I finally found a great solution. It turns out deleting all of your browsing data is not necessary. This problem comes down to one solitary cookie. Delete this cookie and life is good again.
