From a1d2a9077978602f92c4ea38ce4f85a45ce821b3 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Thu, 19 May 2016 11:47:18 +0200 Subject: [PATCH] s3:rpcclient: make use of SMB_SIGNING_IPC_DEFAULT This means we'll use the "client ipc min protocol", "client ipc max protocol" and "client ipc signing" options. But "--signing=no" or "--signing=required" still overwrite "client ipc signing". The following can be used to alter the max protocol rpcclient --option="client ipc max protocol=SMB2_10" 172.31.9.163 -Uadministrator%A1b2C3d4 -c "getusername" Account Name: Administrator, Authority Name: W4EDOM-L4 rpcclient --option="client ipc max protocol=NT1" 172.31.9.163 -Uadministrator%A1b2C3d4 -c "getusername" Account Name: Administrator, Authority Name: W4EDOM-L4 rpcclient 172.31.9.163 -Uadministrator%A1b2C3d4 -c "getusername" Account Name: Administrator, Authority Name: W4EDOM-L4 BUG: https://bugzilla.samba.org/show_bug.cgi?id=11927 Signed-off-by: Stefan Metzmacher Reviewed-by: Jeremy Allison Autobuild-User(master): Jeremy Allison Autobuild-Date(master): Sat May 21 05:01:15 CEST 2016 on sn-devel-144 (cherry picked from commit 2eb824fbaf61dfc5e9c735589c80c41379dabe86) --- source3/rpcclient/rpcclient.c | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) diff --git a/source3/rpcclient/rpcclient.c b/source3/rpcclient/rpcclient.c index a35e422..ebe72b9 100644 --- a/source3/rpcclient/rpcclient.c +++ b/source3/rpcclient/rpcclient.c @@ -944,6 +944,7 @@ out_free: const char *binding_string = NULL; char *user, *domain, *q; const char *host; + int signing_state = SMB_SIGNING_IPC_DEFAULT; /* make sure the vars that get altered (4th field) are in a fixed location or certain compilers complain */ @@ -1116,6 +1117,16 @@ out_free: } } + signing_state = get_cmdline_auth_info_signing_state(rpcclient_auth_info); + switch (signing_state) { + case SMB_SIGNING_OFF: + lp_set_cmdline("client ipc signing", "no"); + break; + case SMB_SIGNING_REQUIRED: + lp_set_cmdline("client ipc signing", "required"); + break; + } + if (get_cmdline_auth_info_use_kerberos(rpcclient_auth_info)) { flags |= CLI_FULL_CONNECTION_USE_KERBEROS | CLI_FULL_CONNECTION_FALLBACK_AFTER_KERBEROS; @@ -1143,7 +1154,7 @@ out_free: get_cmdline_auth_info_domain(rpcclient_auth_info), get_cmdline_auth_info_password(rpcclient_auth_info), flags, - get_cmdline_auth_info_signing_state(rpcclient_auth_info)); + SMB_SIGNING_IPC_DEFAULT); if (!NT_STATUS_IS_OK(nt_status)) { DEBUG(0,("Cannot connect to server.
