Hello Guys,
I've got a strange behavior here. On a fresh installed Arch and I have massive lags from my Mint machine via ssh.
Login is via ssh_key - no problem. But when I write on the console - the Arch machine is in my LAN - there are lags.
So I fired up tcpdump.
And there are dozent (~100) of lines with these just by pressing one key:
06:16:00.563956 IP 10.0.0.147.41132 > 10.0.0.198.22: Flags [P.], seq 67908:67944, ack 82063, win 1225, options [nop,nop,TS val 420468524 ecr 2269267690], length 36
06:16:00.564237 IP 10.0.0.198.22 > 10.0.0.147.41132: Flags [P.], seq 82063:82099, ack 67944, win 120, options [nop,nop,TS val 2269267710 ecr 420468524], length 36
sometimes there is a:
06:15:59.935765 IP 10.0.0.147.41132 > 10.0.0.198.22: Flags [.], ack 80911, win 1203, options [nop,nop,TS val 420467896 ecr 2269267074], length 0
Logging in from another machine there are just 3 lines (by pressing one key).
I've also tried with a different user and without any ssh_keys.
I know this is not really an arch failure. But the fact that I have this only on the arch machine with my Mint, makes me headaches.
Does anybody have any ideas?
Thanks

Do you use the same terminal emulator on all clients? Do you have such lags when logging in from a linux console? (The arch host might simply lack the terminfo for the client TE, not all are part of ncurses)
For clarification:
There're no problem w/ other ssh clients (how many - round about) to that concerned arch server and there're also no problem w/ the concerned Mint client to various other ssh servers?

Well, no. And now I've tried putty - on my machine. So the lag is still there BUT: now tcpdump show just a regular "conversation" (4 lines) by pressing 1 key.
So what does putty different as my terminals (mate or gnome)
But anyway the lag is there.. so I dont know. I mean I can fireup some rdp - with much more data, and a simple typing on the remote shell laggs?

No, and no
Thanks anyways

Repaints? The lag could be strictly local.
Have you tried the behavior when being logged in from a console (the DOS-like, no GUI thing you get when pressing ctrl+alt+f3)

well, thanks ok, no lags.
But again how to see, why the f*** is it sending ~100 lines by typing just 1 key.

What TE are you currently using on Mint and does the arch system have the terminfo for that?
Have you tried using eg. xterm?
As for the lags: what DE do you run on Mint? Cinnabun? XFCE?
