Cannot see users on other nodes

Question

Calendar users cannot see the users on other nodes.What should I do?
<P>
You may not have configured your node-to-node connections. Use
Connect Nodes or uninode -edit. Your fully qualified domain name for
your network exceeds 16 characters. Shorten your domain name or setup
a shorter alias.
<P>
Follow these instructions after you have shortened the domain name or
created a shorter alias. These instructions are also available in the
Release Notes. If the fully qualified domain name for your network
exceeds 16 characters, it will be necessary to shorten the host name
of all the servers in the Calendar Server.network . These instructions
must be carefully followed to avoid causing problems with the network.
Ensure that the procedure is applied to ALL nodes in the Calendar
network.
1) The following procedure should be carried out on each server in
the Calendar network:
a) Bring the Calendar services down.
% unistop -y
b) Run the unidbfix command in export mode.
% unidbfix -export -n node-id
This will create a remotenode.ini file for each node on the server.
The file is located in the node's perm directory.
Example:
If you have two nodes on the server ROCK, node 1(in N1) and node
(in N2), the files are:
/users/unison/db/nodes/N1/perm/remotenode.ini
/users/unison/db/nodes/N2/perm/remotenode.ini
The remotenode.ini file will look something like this:
[1]
RN_NUMCONNECT = 2
RN_SURNAME = "unison"
RN_GIVENNAME = "unison"
RN_ORGUNIT1 = "uni2"
RN_ORGUNIT2 = "openmail"
RN_ORGANIZATION = "ABC Corp"
RN_ACCESSMETHOD = 2
RN_SERVICENAME = "unieng"
RN_HOSTNAME = "rock"
[2]
RN_NUMCONNECT = 2
RN_SURNAME = "unison"
RN_GIVENNAME = "unison"
RN_ORGUNIT1 = "uni4"
RN_ORGUNIT2 = "openmail"
RN_ORGANIZATION = "ABC Corp"
RN_ACCESSMETHOD = 2
RN_SERVICENAME = "unieng"
RN_HOSTNAME = "rock"
2) Once you have run unidbfix in export mode on all the servers,
proceed as follows:
a) Compare the remotenode.ini files and verify that the
     entries are the same. In each file, you will note that
     an entry for the local node is not included.
b) Edit one of the files (on any of the servers). This file
     will be referred to as the master file. Add the appropriate
     entries for the local node (copy the section from one of
     the other files). Modify the RN_HOSTNAME in each of
     the sections of the master file to shorten the name.
c) Copy the master file in the perm directories of each node
     on all the servers.
3) Once the master file is in the perm directory of all the nodes,
proceed as follows on each server:
a) Run the unidbfix command in the -import mode.
% unidbfix -import -n node-id
b) Edit the nodes.ini file on the hub server and make the
     same changes to the host names. You do not need to apply
     the changes.
c) Edit the [UTL] section of the /users/unison/misc/unison.ini
     file and change the host name.
d) Start up the services.

Answer 1

If images are missing then check that you aren't blocking images from some domains.
*Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
*Check the permissions for all sites on the about:permissions page, via the location bar
*Check that images are enabled: Tools > Options > Content: [X] Load images automatically
*Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).
If an image in the list is grayed and there is a check-mark in the box "<i>Block Images from...</i>" then remove that mark to unblock the images from that domain.
Make sure that you do not block third-party images permissions.default.images
*http://kb.mozillazine.org/Images_or_animations_do_not_load
There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.
