termshare

Quick and easy terminal sharing for getting quick help or pair sysadmin'ing.

Share interactive control with a copilot and/or a readonly view of your terminal with others. Copilots and viewers can use the client or a web-based terminal.

THIS IS JUST A FORK

For the original version please go to https://github.com/progrium/termshare

Installation

For Linux and OSX:

curl -L https://github.com/lalyos/termshare/releases/download/v0.3.0/termshare_v0.3.0_$(uname -s)_x86_64.tgz| tar -xz -C /usr/local/bin

Usage

The original server has expired ssl certs. So I did created an unsecure server, which works, but be avare of man in the middle attacks, so dont share any sensitive data on that channel:

termshare -n -s=termshare.sequenceiq.com:9999

Issue with the original version

Lately i faced this issue:

panic: Post https://termsha.re:443/c4a9d55c-8038-4622-6fb5-a66105f61a36: x509: certificate signed by unknown authority

But a simple recompile solved my problem ...

tl;dr

I spent almost a day to figure out, but still couldn't find out the root cause. termsha.re is using HTTPS. Its certificate is signed with this chain:

• COMODO_RSA_Domain_Validation_Secure_Server_CA
• COMODO_RSA_Certification_Authority
• AddTrust_External_CA_Root

Looks like golang is having problem to accept it. Golfing itself doesn't have any cert storage its using it from the OS. In https://golang.org/src/crypto/x509/root_darwin.go you can see the source is: /System/Library/Keychains/SystemRootCertificates.keychain

Is my keychain missing something?

So it seems like my OS X keychain's ca cert list is missing something. But:

• original termshare shows unknown authority.
• recompiled termshare connects fine.

Further mystery:

• I have an MacBookPro13 with OS X 10.10.3, where the original termshare works fine
• My new MacBookPro15 with OS X 10.10.3, the original termshare complains about certificate signed by unknown authority
