<div dir="ltr">I started, and then stopped using mosh several years ago. I find that mosh has two disadvantages:<div><br></div><div>(1) After dropping the initial ssh connection, it doesn't keep /var/log/wtmp updated (see "man who") to indicate that someone is logged into the system. I ran afoul of this when using mosh on an HPC system, where the administrators didn't know whether I was trying to hide the fact that I was logged in, and disabled my account (until I explained). Their usage policy now forbids using mosh.</div><div><br></div><div>(2) Mosh uses a unique session key. If I am logged into a remote system, and e.g. need to reboot my laptop, then it is impossible to continue an existing session. (That's by design, but still inconvenient for me.)</div><div><br></div><div>I have now switched to using autossh and tmux. autossh will try to re-establish the connection when it drops (network outage, moving the laptop to a different wireless network). When I need to reboot, I need to run autossh manually, but that's a small price to pay. tmux will keep my remote session alive and allow me to reconnect.</div><div><br></div><div>-erik</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Fri, Dec 21, 2018 at 12:39 AM Chamunks <<a href="mailto:chamunks@gmail.com">chamunks@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="ltr">You need to have Mosh installed and a range of ports opened. </div><br><div class="gmail_quote"><div dir="ltr">On Thu, Dec 20, 2018 at 2:39 PM CrankyOldBugger <<a href="mailto:crankyoldbugger@gmail.com" target="_blank">crankyoldbugger@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>I was interested in Mosh a year or so ago, but never actually got using it.
