--- Begin Message ---Package: erlang-base Version: 1:13.b.4-dfsg-5 Severity: wishlist Tags: upstream, patch Hello, when used in conjunction with ejabberd, I only need to run erlang programs on one single machine. It seems advisable that in such cases the epmd binds only to the loopback address. (a similiar option for the rpc portmap daemon exists) The following patch allows for such an option. This would make it possible to start e.g. ejabberd with -epmd "epmd -loopback" Bye, Joerg --- erts/epmd/src/epmd.c.orig 2010-06-09 11:12:51.000000000 +0200 +++ erts/epmd/src/epmd.c 2010-06-09 11:19:55.000000000 +0200 @@ -248,6 +248,7 @@ g->silent = 0; g->is_daemon = 0; + g->bind_loopback = 0; g->packet_timeout = CLOSE_TIMEOUT; /* Default timeout */ g->delay_accept = 0; g->delay_write = 0; @@ -283,6 +284,9 @@ } else if (strcmp(argv[0], "-daemon") == 0) { g->is_daemon = 1; argv++; argc--; + } else if (strcmp(argv[0], "-loopback") == 0) { + g->bind_loopback = 1; + argv++; argc--; } else if (strcmp(argv[0], "-kill") == 0) { if (argc == 1) kill_epmd(g); @@ -468,7 +472,7 @@ static void usage(EpmdVars *g) { - fprintf(stderr, "usage: epmd [-d|-debug] [DbgExtra...] [-port No] [-daemon]\n"); + fprintf(stderr, "usage: epmd [-d|-debug] [DbgExtra...] [-port No] [-daemon] [-loopback]\n"); fprintf(stderr, " [-d|-debug] [-port No] [-names|-kill]\n\n"); fprintf(stderr, "See the Erlang epmd manual page for info about the usage.\n"); fprintf(stderr, "The -port and DbgExtra options are\n\n"); --- erts/epmd/src/epmd_int.h.orig 2010-06-09 11:11:48.000000000 +0200 +++ erts/epmd/src/epmd_int.h 2010-06-09 11:12:32.000000000 +0200 @@ -316,6 +316,7 @@ int debug; int silent; int is_daemon; + int bind_loopback; unsigned packet_timeout; unsigned delay_accept; unsigned delay_write; --- erts/epmd/src/epmd_srv.c.orig 2010-06-09 11:20:27.000000000 +0200 +++ erts/epmd/src/epmd_srv.c 2010-06-09 11:22:54.000000000 +0200 @@ -173,7 +173,10 @@ { /* store port number in unsigned short */ unsigned short sport = g->port; - SET_ADDR_ANY(iserv_addr, FAMILY, sport); + if (g->bind_loopback) + SET_ADDR_LOOPBACK(iserv_addr, FAMILY, sport); + else + SET_ADDR_ANY(iserv_addr, FAMILY, sport); } #ifdef _OSE_

In fact, there is a command line option. -address. It was introduced in version R14B03. So, I'm closing this bug. Cheers! -- Sergei Golovan
