Thomas Wolf created SSHD-1269: --------------------------------- Summary: TCP/IP remote port forwarding with wildcard IP addresses doesn't work with OpenSSH Key: SSHD-1269 URL: https://issues.apache.org/jira/browse/SSHD-1269 Project: MINA SSHD Issue Type: Bug Affects Versions: 2.8.0 Reporter: Thomas Wolf
Looks like a recurrence of SSHD-792. To reproduce, take the {{Sshd1055Test}} from [PR 227|https://github.com/apache/mina-sshd/pull/227]. That one uses OpenSSH 9.0 to set up a remote port forwarding on an Apache MINA sshd server using {code} ssh ... -R 127.0.0.1:0:someHost:somePort ... {code} That works. The server chooses a port A, and a client connecting to 127.0.0.1:A is forwarded to someHost:somePort. Now change that test to use either {{-R 0.0.0.0:0:someHost:somePort}} or {{-R 0:someHost:somePort}}. These should work equally well. However, the test then fails; the OpenSSH client complains about {code} debug1: client_request_forwarded_tcpip: listen 127.0.0.1 port 56054, originator 127.0.0.1 port 56055 WARNING: Server requests forwarding for unknown listen_port 56054 {code} where 56054 is the port chosen by the server. This appears to be caused by the Apache MINA sshd server sending back in the "forwarded-tcpip" request the _bound_ address (127.0.0.1); but OpenSSH expects the original (0.0.0.0, or empty). Probably Apache MINA sshd should send back the original address, but with the bound port. (Note: this is also reproducible using OpenSSH 7.9.) -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@mina.apache.org For additional commands, e-mail: dev-h...@mina.apache.org
