Hi all. When proxying some traffic, and when home server becomes unresponsive, after some time within timeout, freeradius fails to allocate new proxy socket with this message: Error: Failed binding to proxy address * port 5815: Address already in use Note that the base proxy address is 5814 in my case. Some requests gone through port 5815 before server had started complaining. Dump shows that total of 512 unresponded requests were sent, then the error occured. Attached is my patch for this problem. It corrects two separate mistakes, which in summary caused undesired behaviour. -- Pavel Levshin OJSC "Megafon" diff -ur freeradius-server-2.1.7/src/main/listen.c freeradius-server-2.1.7-patch/src/main/listen.c --- freeradius-server-2.1.7/src/main/listen.c 2009-09-14 18:43:29.000000000 +0400 +++ freeradius-server-2.1.7-patch/src/main/listen.c 2009-10-14 17:37:30.000000000 +0400 @@ -1701,7 +1701,7 @@ } if (sock->port > last_proxy_port) { - last_proxy_port = sock->port + 1; + last_proxy_port = sock->port; } if (!old) old = sock; @@ -1733,15 +1733,14 @@ /* * Keep going until we find an unused port. */ - for (port = last_proxy_port; port < 64000; port++) { + for (port = last_proxy_port + 1; port < 64000; port++) { int rcode; sock->port = port; rcode = listen_bind(this); if (rcode < 0) { - listen_free(&this); - return NULL; + continue; } /*
