Hi All, |

I have noticed this problem when I try to connect to two different machines in |
4 |
two different continents. One is on cable (US) the other on ISDN ADSL |
5 |
(Greece). In the evening and sometimes weekends ssh connections from my |
6 |
laptop to these two PCs are either taking ages or time out. This is ssh |
7 |
connections to sshd which is listening to random ports in the 200+ or 12000+ |
8 |
ranges. If I eventually manage to connect the latency is ridiculous - up to |
9 |
5 seconds! Sometimes I enter a passwd, if I can get that far and then wait |
10 |
for hours with no response. Eventually, I have to close the terminal. |

Tracerouting does not get through although some clever tcptraceroute strings |
13 |
may on occasions (intermittently) get through. |

|
15 |
Both servers run on domestic networks. BTW, ssh-ing to servers in datacenters |
16 |
with their big fiber-optic pipes, although relatively slow in peak times, |
17 |
always gets through. |

The strange thing is that there is no problem talking to these boxen while |
20 |
they run Google-Talk, it's only the ssh connection that seems to suffer. |

Have you come across such a problem before? How can I troubleshoot it? In |
23 |
this day and age of broadband connections it seems strange to get worse |
24 |
performance than on a dialup network . . . I mean I have run VNC connections |
25 |
over a 56k dial up with more responsiveness than this! |
