I don't know why I would have a firewall or network problem, the set up |
19 |
I have has been here for 8+ years. The setup is like this. In the |
20 |
basement the cable internet comes in and into a cable modem. Then an |
21 |
RJ45 out of the cable modem into an 8-port NETGEAR Router/Switch. |
22 |
Upstairs is a hub with three computers connected and this hub is |
23 |
connected to the switch in the basement. The only problem I ever had |
24 |
was when the dhcp address changed, then it needed to be added to the |
25 |
PORT FORWARDING section of the switch with port 22. |
26 |
|
27 |
Remember I can still log in remotely from Redhat and Suse boxes that |
28 |
weren't updated with the new openssh. |
29 |
|
30 |
When ssh'ing in from a remote updated Gentoo box the "Read from socket |
31 |
failed: Connection reset by peer" message is displayed. This message is |
32 |
not displayed when trying to ssh in from inside the network. |
33 |
|
34 |
Alright, back to the task at hand. When I tell the switch to "Respond |
35 |
to Ping on Internet WAN Port" the ping statistics are good: 3 packets |
36 |
transmitted, 3 received, 0% packet loss, time 2007ms. |
37 |
|
38 |
I'm not sure where to go from here. |
39 |
|
40 |
Is there anything in the sshd_config or ssh_config files that I need? |
41 |
After the upgrade the new files were merged with the current. |
