Data does not get collected

I am dealing with a really weird problem . I have setup graphite and managed to run the client example without a problem, data was collected as intended.

Once I tried to push some data from a remote machine, however, data seems to be dropped/rejected/missing.

I can telnet to the remote server on the graphite ip/port, raw telnet messages do not work.

The carbon logs in debug mode show the following:

16/04/2013 21:11:23 :: [listener] MetricLineReceiver connection with REMOTE_SERVER_IP:47704 established
16/04/2013 21:11:23 :: [listener] MetricLineReceiver connection with REMOTE_SERVER_IP:47704 closed cleanly

When checking carbon's internal stats, I see there are update operations, metrics received operations, commited points operations, but there are no points per updates, which seems weird.

The thing that is bugging me the most is that the data push works from localhost, it does not work from a remote machine. Again telnetting from the remote machine is ok, so I don't think it is a firewall issue.

I tried to push to the following schemas every 15 seconds:

[default_1min_for_1day]
pattern = .*
retentions = 60s:1d

[schema_name]
priority = 100
pattern = ^pigeon\.
retentions = 10s:14d

I tried messages that end with "\n" and with "\r\n" both do not work.

Anyone dealt with something similar?

The versions I am using is 9.10 stable.
