Greetings!
I'll try not to make this "blog-like" and just indicate information I feel is relevant and deal with my questions. But, of course, if I failed to provide anything about which you're wondering, please just ask and I will gladly provide that information! Be it "run this command and what is the output" or whatever!
I'm trying to use my new Linux laptop to be able to ssh-login to my desktop Linux computer. My desktop Linux is a Fedora Core 4 which I installed in September of 2005. My new laptop is Fedora 18.
I do not have a static IP, but I have DDNS set up. And I know it is working, because I already had cameras at my house, and I can logon connect to it from web browsers using http://<my username>.dyndns.org.
I can, on my desktop Linux, do an "ssh barry@localhost" and the login works perfectly, so I believe ssh is working fine there.
If I do an "ssh barry@<my username>.dyndns.org" from my laptop, after a delay, it reports: "ssh: connect to host os9barry.dyndns.org port 22: Connection timed out".
Here is my first wonder/question...
I have set my DVR to the IP address of 192.168.1.101 and have that IP address explicitly mentioned in the D-Link EBR-2310 wired router I have.
My Linux system is actually Ethernet/network connected to a Sun Ultra 30 (running Solaris 8) and so I have some different (I believe the word is) subnets here. My Linux system is 192.168.2.1 and the Sun Solaris system is 192.168.1.201.
The Sun computer is a mail host (once every five minutes, it checks my ISP and if I or my mother have any Internet email, it transfers it to the local Sun hard drive and deletes it, so far as the ISP is concerned) and a router, having a network connection to the Linux system as well as a different network connection to the EBR2310 wired router and thusly the cable modem.
(The Sun mail files are NFS mounted on the Linux, and any email that I or my mother use on the Linux system, using mutt -- my FAVORITE email program, is read that way.)
I'm using <my username>.dyndns.org, as that equates to my Internet IP which my ISP has assigned to me.
It IS a router, but I'm wondering whether the 192.168.1.<whatever> IPs that the Advanced portion of my D-Link EBR-2310 is successfully accessing (such as to my DVR) might be a problem since I'm using the same thing in the ssh command, but the IP address in my Advanced page is "192.168.2.1"?
Wording this another way, since I may not be using proper terms, the Advanced page of my router has "192.168.1.101" for the DVR (and this is working), but it has "192.168.2.1" for the Linux system to which I want to ssh-login. (I tried setting the netmask to 255.255.0.0 instead of 255.255.255.0, but that didn't work, either.)
Okay... I'll stop for now. This is a question in my mind, and I'll get this answered and/or get some "warm and fuzzy" opinions from people who understand this better than I do that it should be okay before I go onto other things. :-)
Again, ask questions, and I'll do my best to provide answers as quickly as I can. (It may be days, worst case scenario.)
