Passes simple telnet test and note there is still a (tight) window to have this in F16
Comment 8 Jóhann B. Guðmundsson 2011-09-12 19:09:59 EDT
Once package and shipped your package should no longer have to depend on xinetd https://fedoraproject.org/wiki/Packaging:Guidelines:Systemd https://fedoraproject.org/wiki/Packaging:ScriptletSnippets#Systemd
Comment 9 Fedora Admin XMLRPC Client 2013-04-02 09:25:09 EDT
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Comment 10 Fedora End Of Life 2013-04-03 12:25:37 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Comment 14 Francis.Montagnac 2013-04-30 03:17:36 EDT
rsh fails between two machines having only IPV4 adresses if one uses the new rsh.socket systemd file to activate it. The error message ares: (IPs and names made anonymous): rshd: Host addr ::ffff:X.Y.Z.T not listed for host A.B.C rshd: rsh denied to root@A.B.C as root: Host address mismatch for %s It works if: - one starts this service the old way with xinetd - or if one change rsh.socket to use IPV4, ie: ListenStream=a.b.c.d:514 where a.b.c.d is the IP number of the machine
Comment 15 Michal Sekletar 2013-04-30 12:07:18 EDT
I was trying to reproduce the issue. I used two clean Fedora installations with out of box settings, except IPv6, which I disabled entirely on both hosts. I tried rsh and rlogin and it worked as expected. Can you describe your environment and settings in greater detail?
Comment 16 Francis.Montagnac 2013-05-01 03:05:24 EDT
> Can you describe your environment and settings in greater detail? Our network uses a DHCP and DNS IPv4 only servers. The fedora machines have IPv6 enabled and obtain their IPs through DHCP. You can reproduce this problem on a single machine as follows: - configure it to use IPv6 (the default) Then rsh.socket will listen on IPv6 only (see below), while allowing IPv4 connections (with IPv4-on-IPv6 if I understand correctly) - add localhost4 to /root/.rhosts One obtains: rsh localhost4 hostname Host address mismatch for localhost /var/log/messages May 1 08:40:57 local36 systemd: Starting Remote Shell Facilities Server... May 1 08:40:57 local36 systemd: Started Remote Shell Facilities Server. May 1 08:40:57 local36 rshd: Host addr ::ffff:127.0.0.1 not listed for host localhost May 1 08:40:57 local36 rshd: rsh denied to root@localhost as root: Host address mismatch for %s May 1 08:40:57 local36 rshd: rsh command was 'hostname' rsh.socket listen on IPv6 only, unlike ssh that listen on IPv4 and IPv6: lsof -i tcp:514,22 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME systemd 1 root 56u IPv6 41015 0t0 TCP *:shell (LISTEN) sshd 777 root 3u IPv4 16626 0t0 TCP *:ssh (LISTEN) sshd 777 root 4u IPv6 16628 0t0 TCP *:ssh (LISTEN)
Comment 17 Francis.Montagnac 2013-05-02 04:09:30 EDT
Looking at the sources, I think that it should suffice to modify the following: rshd/rshd.c: in the findhostname function, replace the call of inet_ntop that initialize remote_address by: getnameinfo (fromp, fromlen, remote_address, INET6_ADDRSTRLEN, NULL, 0, NI_NUMERICHOST) rlogind/network.c: rewrite the soaddr_eq_ip function to handle v4-mapped-on-v6 addresses I may try to do that myself. Let me know.
Comment 18 Francis.Montagnac 2013-07-01 11:27:31 EDT
I saw that you updated recently the RPM to the version 0.17-72 - fix handling of non-native IPv6 connections via AF_INET6 socket I tested it, and it works. Thanks a lot.
