In
order to make a ssh connection to Grex, you need an ssh
client. It is likely that you already have one, because most
modern systems come with one built in.
There are several cases to consider, depending on what kind of
machine and connection you are using:
If you have a PC running a 32-bit Windows operating system
(Window 95, 98, NT, 7, 10), then you are unlikely to have an ssh program
built in. grex requires ssh for connecting, so you would need to install
an ssh client. If this doesn't work, go back to the
top of this page, and make another selection.
Please see the Grex ssh
Page for information about alternate ssh programs.
If you are running an older version of Windows or Windows
for Workgroups on your PC, you may not have a built in ssh
program, and you may also need TCP/IP stack software. See the
Grex ssh Page for information
on how to get what you need.
If you have a Macintosh, you need a ssh client program.
See the Grex ssh page for
information about Macintosh ssh clients.
If you are using a terminal emulator, then it does not matter
whether you are connecting from a Macintosh, or PC. You will be
running the ssh client on the host machine, which is usually a
unix machine. If you are dialing into a Free-net or Community
network, using a terminal emulator, you may be presented with a
menu of options. You will need to get help from the people who
run that machine to find out how to do an ssh connection from
it. If you are able to access a unix command prompt, or if your own
machine is a unix machine, then you should be able to type "ssh
**username**@grex.org" to start the connection to Grex (substitute
your Grex user name for **username**). You do not need a special ssh
client, because it is built in to all unix systems.
This occurs when your browser has not been
configured to know where your ssh client is located. To
correct this, you must configure your browser. There is a
slightly different way to do this for each different browser.
Generally, there is a way to assign ssh connections to an
application. Assign ssh connections to your ssh client.
If you do not know what your ssh client is, then you should read the previous section of this page.
Once you have selected a good ssh client program to be your
browser's ssh application, your browser should not have any
further trouble following ssh links.
There are a number of reasons why this might be
happening:
Your DNS is not configured properly. This can easily be
tested. Try sshing to Grex's IP address. Of course you have
to know the IP address. We can tell you that at the time this
page was last updated, Grex's IP address was 162.202.67.158, but
it may change at any time. If you are in doubt, view this page to see if it has changed.
Try substituting that IP address for the name "grex.org" when
you ssh, to see if it works any better. If it does, then you
have a problem with your machine's configuration for DNS. You
really need to correct this problem, because you should not
rely on the IP address to remain constant. In order to
configure DNS properly on your machine, you will need to
contact your Internet Access Provider's system help desk, or
help website.
If, on the other hand, this does not help, then DNS is not
your problem.
You are connected to the net via a firewall. A firewall is
a router that filters (blocks) certain packets. Firewalls are
usually installed to protect private networks, or to limit the
usage of certain services. Users connecting from corporate
intranets are most likely to encounter firewalls. Very often it
is possible to ssh through a firewall, but unfortunately, we
cannot help you find a way to do this. If you need to traverse
a firewall to get access to the internet, you should contact
the firewall or security administrator on your intranet and ask
how to make a ssh connection to the internet.
Grex might be down at the moment, or there may be
disruptions in the proper functioning of the internet. In this
case, there is little you can do except wait a while, and try
again later. If Grex were down, or the network were broken,
though, it is not likely that you would be seeing this page,
because it is provided by Grex's web server, unless perhaps you
are looking at a copy of it that was cached by your browser
when the connection to Grex was clear.
Your domain or IP address is in a black or block list. Grex
subscribes to several lists which contain IP address known to
be associated with illegal activity. Unfortunately, some of these
may be dynamically assigned by your Internet Service Provider,
and you may be blocked from connecting to Grex. Ideally, this is
something your ISP should take care of (e.g. removing the IP
address from block or black lists, or making the IP address
unavailable to users on their system). Grex staff may be
able to help but if the IP address continues to show up on
black lists, there's not a lot we can do.
If none of the above seems to apply to you, please fill out
the following form. The more information you provide, the more
likely the Grex Staff will be able to help you discover what is
wrong. Therefore, please take the time to fill the form out
carefully. The Grex staff will respond by email to your account
or to the e-mail address you provide, so make sure it is
correct.
Please fill out this form and include
as much detail as possible about your problem. The e-mail address
is optional, but if you do not specify one, the staff will
respond with mail to your Grex account. This will only be helpful
if you have a way to connect and read your mail.
