without an ssh login on your mail box
For a long time I didn't have shell access to the machine on which I was getting my email. For example my university email was accessed by POP but I didn't have ssh access to that account. So I thought that ssh forwarding couldn't help me.
But it turned out that it could have. Sure it is not a secure tunnel all the way but it does help with wireless networks. laptop --- basestation --- wiredbox --- mailserver If you have a wired-box off the wireless segment which you can ssh to, say your home cable box or an account on a friend's, then you can tunnel so that the wiredbox acts as a proxy to your mailserver - the section between the wiredbox and the mail-server is not encrypted though! So it isn't really all that great but it does protect against the casual wireless sniffer. Again - the password will be in **plaintext** between the box you ssh to and your mailserver. This works for me:
This says to forward localhost:11011 -> mailbox.uni.edu:110 _via_ mysshloginbox.com (-N says "don't execute any commands - just forward") Notice that the difference between this line and the ones above is that there are two different server names in the line. I had read the "secure pop over ssh" tip a million times before really reading the ssh forwarding syntax. I was pretty chuffed to see this. It can probably be adjusted for SMTP sending as well but I haven't tested this. This is also very useful for corporate firewall situations in which 110 and 25 are blocked but, by geek demand, 22 is open ;) |
