I was wondering what everyone's thoughts were on a simpler way to exclude addresses from having listeners on them. I know a lot of people have multiple subnets, especially larger corporations. Some networks are non-route-able, and therefor unsuitable for use with SSH, aside from communication between other servers on the same subnet. Given that we may want to exclude those non-route-able

https://bugzilla.samba.org/show_bug.cgi?id=8355 Summary: Use pointer after freeaddrinfo() Product: rsync Version: 3.0.8 Platform: All OS/Version: All Status: NEW Severity: critical Priority: P5 Component: core AssignedTo: wayned at samba.org ReportedBy: andrey at zonov.org

The last versions of rsync fail to compile on Tru64 Unix (alpha), because of a typo in configure.in. The problem is that the code in configure check for sockaddr.sa_len, while the code uses sockaddr.sin_len. This patch fixes the problem. Please include it in the next version of rsync. diff -ur src-2.6.0/configure.in src-2.6.0-local/configure.in --- src-2.6.0-local/configure.in

I've just upgraded my rsync server to 2.5.1 (before, I was using 2.4.6), without changing anything in /etc/rsyncd.conf, and now, I have this logs each time a client connect to server: 2002/01/07 18:33:03 [10432] rsync: reverse name lookup mismatch on fd3 - spoofed address? 2002/01/07 18:33:03 [10432] rsync on admin/sbin/padmin_update.sh from UNKNOWN (172.16.65.14) 2002/01/07 18:33:03 [10432]

...blem with the latest version (2.9.9p2) and previous versions of OpenSSH when using portforwarding und Solaris 8 x86. It seems like the getaddrinfo() function on Solaris 8 x86 is somehow broken, instead of binding a port to 127.0.0.1, OpenSSH tried to bind it to 1.0.0.127 (1.0.0.127 was the ai->ai_addr returned by getaddrinfo() in channel.c). I could not reproduce this on Solaris 8 Sparc and I assume that Sun developers mixed endianess on the x86 platform. I could fix the problem by marking the getaddrinfo() function as broken on Solaris 8 x86 (#define BROKEN_GETADDRINFO 1). Maybe someone o...
