RE: [squid-users] JAVA Applet notinited

Hello.

My squid is part of my internal DNS Server. I have a (A) to proxy.mycompany.com = 10.0.1.18 and a (PTR) to 10.0.1.18 = proxy.mycompany.com.

All the name on my network are resolved using my internal DNS. If I do a nslookup on my Squid box, all the name are resolved.

I really don't know where to start looking.

Thanks

Jonathan

Googling "netbios name java applet proxy" found chatter regarding known bugs in Java 5 still present in Java 6. The applet loader attempts to do a reverse lookup of a source host ip. It attempts firstly using DNS. That fails for our proxies as they are not in DNS. The applet loader then tries to resolve using netbios name services, but instead of using the WINS server specified for the PC's interface in the MSWindows Networking setup, it attempts to use the proxy, on which there is no netbios server, hence long delays due to request timeouts. The two possible workarounds are a) configure the proxies in internal DNS or b) install Samba netbios services on the proxies. The former is vastly easier and better and was immediately successful."
