Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

I have Redhat Linux 7.1 installed on a
Dell Poweredge 2400. I aslo have WuFTPD, Apache Web Server
installed, both work fine locally on the linux box. But if I try to
ftp from a different machine ( WINDOWS 2000 PROF)
on the LAN, I get a CONNECTION RESET BY PEER message after a long waiting (3 minutes) and nothing else come out. The http also doesn't work from the Windows machine.
I also set up SAMBA on the linux box. I could even see
it in the network neighbourhood from the window
machine, but if I try to access it or map a drive for
it, it hangs for five minutes then drops me off. I
guess it relates to the same problem.
I could ping each other from both sides. I could aslo access database on the linux box from the windos machines. If I try to ftp Windows machines from the linux box, I got a
CONNECTION REFUSED message which is reasonable, since
I didn't activate the FTP service on the Windows machine.
I used an IP tool to scan the ports of the linux box
from the window machine. Ping, port 25 (SMTP),
port 1521 (Oracle) worked ok, but port 20 (ftp-data),
21(ftp), 23(telnet), 80(http) all gave me CONNECTION
RESET BY PEER messages.
I have two ethnet ports on the linux box, both seem working. I only keep one of them active.
I also tried on two different windows machines, both Widnows 2000 Pro, same problem.
I hope some gurus could help me out with this problem.
I suppose my tcpd runs in paranoid mode, which is by default I think.
I don't have DNS server installed on my network. But
I do have entries in /etc/hosts file on the linux box and host file on the window box. Does tcpd block oracle connection if it sees something mismatch?
I installed ftp server in windows and I could ftp windows from linux box.
Is there anyway to log incoming ftp trials on the linux box even it
rejects them with CONNECTION RESET BY PEER?
