问题
When I type in "git push heroku master" I get an error that says:
ssh: Could not resolve hostname heroku.com: nodename nor servname provided, or not known
I am on my computer at work and I believe this problem has to do with proxies/firewall. Does anybody know of a way around this error in the command line? Or any other type of fix? Thanks.
回答1:
try ssh'ing directly to heroku from your command line
ssh git@heroku.com -T
if you don't get a response
! You can only access Heroku by ssh via git push and pull commands.
then it's connectivety issue or a firewall in the way that's blocking your requests.

please make an entry in your ~/.ssh/config to get around this issue. No idea why your network is having issues. You may be behind a proxy and git has to be configured for that outside of your OS settings.
Hope this helps.

I had a heap of trouble when accessing internet via my Zyxel PLA4215. When switching to wireless everything worked fine.
