1. Mobile Network or BlackBerry Q10 hotspot block SSH port 22 Today I go to countryside in annual Tet holiday and have to use Mobile Network (3G/4G) for my work. Unfortunately It seem my Mobile Network blocked port 22 or may be my phone BlackBerry Q10 blocked it. I use my Q10 as Mobile hotspot. I have no problem before, so I think it is caused by either BlackBerry software or Internet Provider. My laptop is Macbook Pro 2017 and my VPS service is DigitalOcean So I guess I can serve ssh in different port (ie. 2222). After some search, I end up with serve SSH in both port 22 and 2222 use Digital Ocean (DO) web console. Yeah, It work ! Need inspect more why caused this problem. BB OS or Internet Provider or event MBP. There are some other issues like keyboard problem with DO web console. Some character like '|' not work. https://www.digitalocean.com/community/questions/i-can-t-type-some-symbols-on-console How special char, symbol called in English ? http://catb.org/j...
