I have to setup my server to receive 20-30 concurrent sftp connections from different clients using same username. I've tried to test this simulation user connections with scp.
The problem is that after the 8th connection all other connections receive a - stalled notification.
1) what would be the settings on the server to disable any incoming connections; 2) is there any iptables/network settings that could cause a limitation like this? Besides all these incoming connection the server should handle about 100 concurrent apache users. Would the apache port 80 connection be in conflict with all the sftp uploading connections?
The server is a CentOS 5.8.
