Best free SSH client on iOS

D4nk m33m335

This is a great SSH client, with support for saving identities, key generation, and port forwarding even in the free version. The only downside is sessions cannot stay open in the background for more than 3 minutes, but that is a limitation of iOS itself, not Termius. I also wish it advised users to use SSH instead of Telnet the first time they use it because Telnet is unencrypted and you should really avoid using it if at all possible. I use Termius for connecting to my Debian server when I don't have my computer on me and need to do something that I can't do through the Webmin interface. The port forwarding feature comes in handy when I need to do something like connect to said Webmin interface remotely or use OpenVPN in public places when it is blocked (Surprisingly, I have run into this problem before, at an airport). Overall, a great app if you have a server and don't want to carry a computer around to access it.



This is a great app! I use it all the time, especially when I am not near a terminal. Or even when I'm near one but just want to do a spot check.

You can set up identities and keys. I just configured it to use RSA public key encryption. I can associate the key with a login and use that configuration to login. Very easy!

You can also save multiple configurations for the different hosts and logins you need. I can now admin my system from anywhere. At dinner, on the trail, or anywhere I have my phone, or tablet, and internet.

You customize your view so different terminal sessions can easily be distinguished. There is also a handy history log of all your login sessions.

I don’t need sftp, but that can be added for the price of a subscription ($10 / year, I believe). For that price you also get snippets (macros), fingerprint recognition, plus more.

(Edit) There was a keyboard issue that made ‘shift’ characters hard to enter (caps/special chars/etc) (There was a workaround, but inconvenient). This was fixed, so I keep my 5-star rating. There is a lot packed into this FREE app! Very nice!

Recent updates broke several ssh servers


As of recent update about 2-3 months ago (the update where they added location services background keep alive), nearly 50 of my Terminus bookmarks/devices freeze right after opening their ssh connection, prior to the update, I had not had any issues in 4 years+ of terminus use. I can still connect to the same devices via telnet without any issues, but using SSH , as soon as the connection opens the app freezes.

I have tested this on various other iOS devices, including a freshly reset device. The freeze issue exists on all iOS devices.

I Was in touch with the developers, they requested several screen recordings and remote SSH access into a sample device w the issue, which they did connected to, but they then stopped any replies / updates to me nearly a month ago. Of course putty and other SSH clients have no issue connecting to the devices ( mikrotik routerOS , and some fedora Linux boxes) , and obviously terminus had no issue connecting to these devices prior to that update.

I will update this review to 4 or 5 stars when the issue is resolved, but it’s very frustrating to have nearly 100 devices entered manually into terminus app, and then a update one day stops half of them from working.
