I am having this weird issue with a server whenever I try to open htop over ssh it hangs, ls works but ls -l hangs after couple of line if I execute history it hangs after printing 50+ line. But mosh seems to working fine. I cant figure out whats the issue here. The server os is ubuntu 20.04

    This could be due to an issue with jumbo frames or the MTU somewhere along the path. Follow the ping tests at https://www.reddit.com/r/sysadmin/comments/737c1z/friendly_reminder_if_ssh_sometimes_hangs/ to see if that helps. – Stefan Lasiewski Sep 03 '20 at 19:30

    If the issue is MTU, the solution is to configure the correct MTU, on the interfaces between the two machines involved (including any router between them). – KHobbits Sep 04 '20 at 00:58
  • To confirm this problem, try the following ping test: https://blah.cloud/hardware/test-jumbo-frames-working/ – Stefan Lasiewski Sep 18 '20 at 18:11
