Operating Systems AIX PING to AIX works but TELNET FTP SSH doesn't work Post 303031675 by gull04 on Monday 4th of March 2019 07:09:51 AM

Hi,

Could you ping the server all the time that you couldn't connect an other way?

Is it a Physical or Virtual? What is the "uptime" on the server? Were problems experienced connecting to any other servers in the same location?

What if anything was in the logs?

Regards

Gull04

NAME
rping - RDMA CM connection and RDMA ping-pong test. SYNOPSIS
rping -s [-v] [-V] [-d] [-P] [-a address] [-p port] [-C message_count] [-S message_size] rping -c [-v] [-V] [-d] -a address [-p port] [-C message_count] [-S message_size] DESCRIPTION
Establishes a reliable RDMA connection between two nodes using the librdmacm, optionally performs RDMA transfers between the nodes, then disconnects. OPTIONS
-s Run as the server. -c Run as the client. -a address On the server, specifies the network address to bind the connection to. On the client, specifies the server address to connect to. -p Port number for listening server. -v Display ping data. -V Validate ping data. -d Display debug information. -C message_count The number of messages to transfer over each connection. (default infinite) -S message_size The size of each message transferred, in bytes. (default 100) -P Run the server in persistent mode. This allows multiple rping clients to connect to a single server instance. The server will run until killed. NOTES
Because this test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions. See the libibverbs README file for additional details. SEE ALSO
