Hi,

I have successfully installed nntp-proxy on a Centos 6.4, I've generated ssl key, but when my client try to connect to the proxies, I've this message in the debug console :

20/05/13 11:12:40 [eventcb:887] Error: Success
20/05/13 11:12:40 [close_client:376] closing client connection 0
20/05/13 11:12:43 [ssl_accept_cb:940] new connection from [ MYIP ]
20/05/13 11:12:43 [get_next_conn:194] Connection 0 is available
20/05/13 11:12:43 [eventcb:864] event received for client connection
20/05/13 11:12:43 [eventcb:874] BEV_EVENT_ERROR
unknown protocol in SSL routines SSL23_GET_CLIENT_HELLO

And I can't login on the proxy, my client disconnect in loop..

Does anybody can help me ?

My vps dont have libevent 2 and it wont works without it what i need to do ? Debian6

hi,

and thanks for a great application!

But I'm wondering if it would it be possible to implement non-SSL connections ?
A possibility to disable logons into the nntp backend would also be appreciated ;)

thanks
frollic

When a user connects, a connection is established to the parrent. When the user disconnects, the parent connection is tore down.

Can we keep parent connections open, and "pool" commands to the parent servers? Allow 20 parent connections, 60 (for example) user connections, and pool the commands - giving the user a timeout error should the queued command take too long to make it to the parent server?

Disable posting access, only allow download ??

Can u add it ?

Can the docs be updated to explain UDP usage:

netstat -lnptu | grep nntp-proxy
tcp 0 0 0.0.0.0:119 0.0.0.0:* LISTEN 7552/nntp-proxy
udp 0 0 0.0.0.0:39051 0.0.0.0:* 7552/nntp-proxy
udp 0 0 0.0.0.0:51992 0.0.0.0:* 7552/nntp-proxy
udp 0 0 0.0.0.0:45871 0.0.0.0:* 7552/nntp-proxy

Hi,

Really good work with this updates (config files, ...)

Can you integrate multiple servers management ?
To permit aggregation of the connexion slots of the servers.

Server 1 : 20 slots
Server 2 : 10 slots

• 28 current connexions through the proxy
• new user connect with 3 allowed slots : create the two first connexions with server 1 and the third with server 2

Regards,

P.S: tu n'etais pas a epitech par hasard ? (oui je suis francais mais je prefere l'anglais sur github)

Hello,

I'm using your soft since few days and I noticed that the service stopped sometimes.

This happens during the closing of the customer and thus its disconnection.

I tried to reproduce the issue while running the program with gdb:
...
06/01/14 00:06:15 [common_readcb:508] client -> proxy: got 6 bytes to read
06/01/14 00:06:15 [common_readcb:517] [4] command finished, 207454 bytes transferred in 0.48 seconds (424.94 kb/s)
06/01/14 00:06:15 [common_readcb:521] [4] command from client: QUIT
06/01/14 00:06:15 [common_readcb:537] [4] command send to server: QUIT

06/01/14 00:06:16 [close_server:404] closing server connection 0
06/01/14 00:06:16 [close_client:379] closing client connection 0

Program received signal SIGPIPE, Broken pipe.
0x000074aab8321040 in write () from /lib/x86_64-linux-gnu/libc.so.6
(gdb)

This issue does not occur every time. From what I can understand, the process reveived a SIGPIPE and colse. SIGPIPE is sent to the process because it tried to write a socket that had been shutdown or is not connected anymore.

Each time there is a line "closing client connection" missing.

Do you have some suggestions? Is it possible to avoid this case?
Or should we make the process ignore SIGPIPE / add an handler for SIGPIPE doing nothing ?

Regards

PS: Un français de plus.

Is there a way i can automatically disconnect connection for user after he download an ARTICLE/BODY?

so one article and he got kicked from connection

via close_connection(conn); ??

Hi

Is this project still maintained and under development ?

Allow the users to be stored in a mysql database.

create database user_db;
use user_db;
create table user (
user_id int(6) not null auto_increment,
username varchar(16) not null,
password varchar(64) not null,
max_connections int(6)) not null
);
