I usually use iTerm when connecting to linux boxes from my Macbook. When also using screen one may notice that e.g. the backspace key doesn’t work properly. I found a solution for this problem:
– Just fire up iTerm
– Click on „Bookmarks“ – „Manage Profiles“
– Keyboard Profiles – xterm (OS X)
– Modify the setting for delete and set the value to „send hex code 8“
After that your ssh sessions may also use the backspace key with iTerm using screen.
