Topic: SSH and internet access

[Cameron]

Hi,
I am reposting I know, but I really would love some solid feedback on this is someone could help...

I have installed ssh and done all that is required to make the java remote access work, it works locally on my intranet but not via the web, i.e. from work.
I am using Telstra adsl and a friend of mine is using optus cable, he has his external proxy settings installed in his e-smith settings and Telstra would not supply me with their proxy information "its transparent" and "we dont have the information to give you" were all I could drag out of the "helpdesk" guy when I rung. It is starting to look like its actually a requirement to have this info to make it work, or is it that after several installs I have missed something simple, I have followed the install instuctions to the letter, the ibay has acess from the internet access (no password required) etc as per the insrtuctions...

PLEASE help...

Kind Regards,
Cameron Stacey

Presumably no-one had the answer - this forum is supported by the user
community. We have users from all over the world, and your question
sounds very Australian specific (most people won't know who Telstra and
Optus are), so a lot of people will have skipped it.

What do the logs say, both on the e-smith server and at work? Are you sure
work is allowing Java to pass?

The Telstra guy is right - their proxy is transparent. I have used it on
dial-up, dedicated and cable modem.

Check your apache, Java and SSH logs. One possibility is a mismatch between
forward and reverse IP address mapping.

Gordon,

thank you for your prompt reply. Work does allow Java to pass as I have accessed my friends pc from there, I also do try to access my page from here via the web too and to no avail.

I have inspected the http logs and could see the differences between when I log on locally and when I try to access from the web, when I access locally I get 4 lines of logs appearing, but from the net I get only one and the no.s 404 and 204 on the end.
Not sure if that info is any use or sheds some light on the issue.

I could not find the java and ssh logs.

I dont know about reverse ip addressing so if you would care to explain and perhaps point me to where I might find the file to try a modification on I would appreciate it.

Thanks again.
Kind Regards,
Cameron Stacey

What URL are you using to access the machine?

People have reported problems accesssing ibays remotely unless they use the
suported "www.{servername.domain}/ibayname". If you are just using "{servername.domain}/ibayname", you may have these problems. Updating
your DNS so that www.servername.domain points to the same machine and
using the www URL is the currently supported method.

No idea about the Java logs - ssh logs to /var/log/messages

Check whether nslookup {yourhostname} matches
                     nslookup {ip address returned by nslookup {yourhostname}}

If it doesn't, you will need to get your DNS records updated. SSH is "paranoid"
as it checks consistency between forward and reverse lookups.
