The Story:
I have installed the Java Version of SAPGUI 7.4 on Ubuntu. However, when I changed to cd ~/.SAPGUI I did not find any configuration file which suppose to be set up by the administrator (who I do not have as it is for the class!). Our lecturer provided us with these information:
[Router]
hcctum=/H/saprouter.hcc.in.tum.de/S/3299/H/
hccmdA=/H/141.44.38.2/S/3299/H/
hccmdM=/H/141.44.39.3/S/3299/H/
hcctumremote=/H/saprouter.hcc.in.tum.de/S/3297/H/
hcctumfailover=/H/hcchasap.informatik.tu-muenchen.de/S/3299/H/
[Default]
name=hcctum
which I put in a configuration file and link it in:
Preferences -> Configuration -> Logon -> Configuration File
When I checked the setting file that resides in ~/.SAPGUI:

After one week of trials, any help will be very much appreciated.
I assume your file is invalid. There are ways to validate your SAPGUILandscape.xml (see note 2112449), or trying to read hundred-page manuals (1, 2), but better not to dig into all this mess and try to stick these simple steps.
SAPgui Java has following connection string format:
conn=/H/<SAP Router>/S/3299/H/<SAP server>/S/32<Instance_no>
Multiple routers (if exist) are separated by /H/ directive.
So I propose you to delete all config files (~/.SAPGUI folder), SAPgui will recreate them anyway. After deletion open SAPgui and enter connection string manually like this:
conn=/H/saprouter.hcc.in.tum.de/S/3299/H/141.44.38.2/S/3299/H/141.44.39.3/S/3299/H/saprouter.hcc.in.tum.de/S/3297/H/hcchasap.informatik.tu-muenchen.de/S/3299/H/hcctum/S/3201
If errors are thrown try to remove some of the routers, ping each of them, detect invalid ones and also ping server (hcctum).
Dunno what is [Default] in your lecturer's notes, but I suppose it denotes server. It is non-standard section (see note 94435).
