The fonts used throughout PROBEwatch are pulled from the applications
default file, which is /usr/kits/PROBEwatch/X/NETscout. It sounds like
this file is not being pulled in, so that the default fonts are being
used instead. To set the path to this file, you need to set the
environment variables shown below:
setenv NSHOME /usr/kits/PROBEwatch
setenv HHHOME /usr/kits/PROBEwatch/help
setenv XUSERFILESEARCHPATH $NSHOME/X/%N
setenv XLIBI18N_PATH $NSHOME/X
The file /usr/kits/PROBEwatch/.netscout is a script that sets these for you.
You should source this script before running "nsman".
For example, use:
# (source .netscout; bin/nsman) &

The long time to display the host list is probably not due to the retrieval
of the hosts, but (for IP-based domains) the conversion of host IP addresses
to names. This can be slow if your /etc/hosts file is very large, or (more
frequently the case), you are using DNS lookup. If there are a lot
of hosts for which DNS lookup fails, the long timeout can me a long
wait for the host list. (The Ultrix version did not do a DNS lookup).
The easiest way to speed up the host list is to create the file:
/usr/kits/PROBEwatch/usr/ipaddr.nam
If this file exists, PROBEwatch uses it rather than /etc/hosts or DNS
to convert IP addresses to host names, resulting in a much faster
host list.
This file has the same format as /etc/hosts, and in fact, you can just
copy /etc/hosts to this file if you want. If you create an empty file,
no IP addresses will be converted to names.
