SSH Tunnels – System administrator’s friend or foe?

Ramdev

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/

    Great Article.

    what is the use of forwarding the tcp port 22, if he could jump off server1 to server2? Better show it with e.g. tcp 80 where an apache is running on server 2. That would make more sense. Otherwise, thanks for the article, can come handy if somebody don’t know about tunnelling.

      You are right Victor, using different target port ( other than 22 ) would have made this example more appropriate. Thanks for dropping the comment.

    ssh tunnels are sys admin’s friend but network admin’s nightmare :)

    i agree :)

    Yes, yes a fine example of something that’s technically possible, but socially may lead to problems. In the US anyway, unauthorized tunnelling can get you fired! Check first with your security group or AUP for your organization.

    hi dsanger, yeah. this is only to use wherever legally allowed  to use:)
