Question

I’ve read tail -f using PuTTY hangs

But please let me ask again.

1. I connect to A using putty.
2. Then I connect to B using ssh.
3. I execute tail -f ...

After some lines tailed terminal stops.

1. Connection is alive.
2. Enter key doesn’t restart tailing
3. I have to CTRL-C and re-execute the tail command.

Any ideas?

It is possible (e.g. if you are tailing a log file) that the file is being rotated: that something renames the file and incoming data is then added to a new file with the original name.

If this is what is happening, use tail -F ... instead of tail -f ....
