telnet on local LAN question
by Paul Allen Newell
Greetings
I am trying to figure out how to get communication between my F14 boxes
on a local wired LAN. The best test case I can come up with to prove
that I don't know what I am doing wrong is telnet.
Each machine has a /etc/hosts looking like (where <name> is the machine
name and <other> is any other machine:
+++
127.0.0.1 <name> localhost.localdomain localhost
<name>.localdomain localhost4
::1 <name> localhost6.localdomain6 localhost6 <name>.localdomain
192.168.2.10 <other1>.localdomain <other1>
192.168.2.11 <other2>.localdomain <other2>
192.168.2.12 <other3>.localdomain <other3>
+++
For the other machines, its name is removed in the 192.168.10.x list and
192.168.2.13 <name>.localdomain <name> is added
Each machines has a /etc/sysconfig/network of:
+++
NETWORKING=yes
HOSTNAME=<name>.localdomain
NTPSERVERARGS=iburst
+++
I didn't see any reference to <name> or <otherX> in
/etc/sysconfig/network-scripts/ifcfg-eth0, so I am not including it ...
if there should be something, I'd love to know! I can't think of any
other place for <otherX> or <otherX>.localdomain, but that's out of
ignorance as I haven't encountered this sort of problem before.
The splash screen for all machines is <name>.localdomain. The command
hostname returns <name>.localdomain.
Ping works great between all of the machines for both <otherX> and
<otherX>.localdomain, lists the 192.168.10.x address like a happy camper
should
But a telnet <otherX> 25 or telnet <otherX>.localdomain 25 fails.
I can't tell if I need to add information about the other machines
somewhere else on <name> or if they really are known but something is
blocking it.
I also can't use mail/mailx between the machines. I noticed that
mail/mailx always resolves <otherX> to <otherX>.localdomain (and sending
to self is resolved to <name>.localdomain), so I changed network to use
the localdomain suffix and added it in /etc/hosts before the instance of
<other>. Neither telnet or mail/mailx worked with just <name>, so I am
pretty certain that I didn't break anything by changing <name> to
<name>.localdomain.
Some machines were already using hostname of <name>.localdomain and my
records aren't good enough to know how I specified the name of the
machine when I installed F14 (it never was an issue as everything worked
until I tested mail/mailx and telnet so I never documented exactly how I
should set machine name on install).
It seems that the telnet problem is a simpler one than the mail/mailx
and if I can at least get telnet working, then I am closer to getting
mail/mailx working.
Any suggestions?
Thanks in advance,
Paul

file transfer in LAN
by CA G Rajesh
Thank you, Mr Stevens.
But, this trusting of port tcp/udp5004 also did not work out. :(
Fedora developers may give an option in firewall to allow seamless communication within LAN. Of course, they may choose to warn the users of potential threat, if any, from such trusting.
If fact, I tried giver too. No hope :(

Google Music Manager - Solved
by SternData
I've got it working. Thanks to a poster on the Ubuntu forums for the tip.
Here's the process:
1) Obtain the Mac address for your network card. Mine is
00:11:95:BC:E5:F3 on em1. (What used to be known as wlan0)
2) In terminal:
cd .config/google-music-manager
sqlite3 Peer.db
In sqlite:
update CONFIG set Value='00:11:95:BC:E5:F3' where Name='MachineIdentifier';
.exit
And we're done!
Once it's running, be sure to set the options so it's not uploading as
fast as possible.
