I'll be repeating stuff here but now it's (ahem) "sorted", in an attempt |
| 29 |
to ease your sleepless nights a little I'll describe the connection... |
| 30 |
|
| 31 |
The work machine is a w2k box sat on internal 10Mb connection behind a |
| 32 |
corporate firewall, details of which are unknown, to a much faster |
| 33 |
outside connection. This work machine also runs sophos (v5.x) which can |
| 34 |
be very intrusive, although I suspect it is our maintainance guys which |
| 35 |
are the cause of that intrusiveness. |
| 36 |
|
| 37 |
It being w2k, I run cygwin and it is via cygwin X server that I connect |
| 38 |
home. From work machine I "ssh -YC" to my FreeBSD box and then "ssh -XC" |
| 39 |
into this debian box (FreeBSD box is a bit ancient so no -Y option). |
| 40 |
|
| 41 |
The FreeBSD box is directly connected to my cable modem. It has two |
| 42 |
network cards and runs samba & NAT + ipfw. It's other FSBD card comes out |
| 43 |
into a router into which my internal network is connected. There's three |
| 44 |
machines attached, one of which is this debian box. Another is my wife's |
| 45 |
w2k machine, the third is the "pending FreeBSD box". |
| 46 |
|
| 47 |
A further complication is my ISP. I do not have a static IP address. My IP |
| 48 |
is on a 2 hour DHCP lease. However, the assigned IP never changes & |
| 49 |
hasn't done even across power failures, which it theoretically should |
| 50 |
have, had the cable modem renegotiated on powerup. |
| 51 |
|
| 52 |
I've remained connected for many hours from work with no apparent issues. |
| 53 |
I would have expected the 2 hour DHCP renew on FreeBSD to cause a break |
| 54 |
but it never has. |
| 55 |
|
| 56 |
If there is a next time for this problem, I'll try and look when I get |
| 57 |
home to see if there's any dangling external connections. |
| 58 |
|
| 59 |
Hmm, methinks I've complicated it further! :-) |
