Assuming this is an NFS mount you are talking about you can set the ports using the guidelines in the following document:

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/s2-nfs-nfs-firewall-config.html

Admittedly, this is for Red Hat but should be easily adaptable for other variants.

How to modify source port in mount application linux
Everything in Java seems to follow capitalization rules except for Hashtable. 

Hashtable&lt;String, String&gt; ht = new Hashtable&lt;String, String&gt;();


as opposed to 

ArrayList&lt;String&gt; a = new ArrayList&lt;String&gt;();


or 

HashMap&lt;String,Integer&gt; a = new HashMap&lt;String,Integer&gt;(); 


Why is this ? Is Hash Table read as just one word (Hashtable) ?
