Template Version: @(#)sac_nextcase %I% %G% SMI This information is Copyright 2008 Sun Microsystems 1. Introduction 1.1. Project/Component Working Name: tftpd server maximum timeout 1.2. Name of Document Author/Supplier: Author: Brian Utterback 1.3 Date of This Document: 23 October, 2008 4. Technical Description This project proposes to add an option to set the tftpd server's (in.tftpd) maximum timeout in order to address CR 6696985. The maximum timeout value (maxtimeout) in tftpd server is currently 25 seconds. This maxtimeout value has proven to be too low for some applications, but currently there is no way to increase it because it is hardcoded. We propose to make it configurable via a new command line flag "-T". This flag will take a single integer value that will set the retransmit timeout(rexmtval) in seconds, which will indirectly change the maxtimeout (5 times the rexmtval). An example of setting of -T to 11 resulting in a 55 second maxtimeout value: # /usr/sbin/in.tftpd -T 11 -s /tftpboot One point to elaborate on. It might seem odd to set the retransmission timer in order to change the maximum timeout. This was choosen because the change is straightforward, and this is how it is currently done in Linux. A minor/patch binding is requested. Diffs for the man page are below: *** in.tftpd.man Thu Oct 23 14:25:59 2008 --- man_in.tftpd Thu Oct 23 14:25:10 2008 *************** *** 10,16 **** SYNOPSIS ! in.tftpd [-s] [homedir] DESCRIPTION --- 10,16 ---- SYNOPSIS ! in.tftpd [-T ] [-s] [homedir] DESCRIPTION *************** *** 40,45 **** --- 43,52 ---- -d Debug.

I would expect that if the man page is updated, this ought to be "Committed" stability. As for SMF, the existing service is still not under SMF (it's a DIY project for customers), so whoever eventually creates that service will likely also have to deal with this as a tunable, but lack of SMF-ing isn't this project. -- James Carlson, Solaris Networking Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 From brian.utterback@sun.com Fri Oct 31 06:14:51 2008 Received: from newsunmail1brm.central.sun.com (newsunmail1brm.Central.Sun.COM [129.147.62.245]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id m9VDEpJ7018165 for ; Fri, 31 Oct 2008 06:14:51 -0700 (PDT) Received: from nwk-avmta-1.SFBay.Sun.COM (nwk-avmta-1.SFBay.Sun.COM [129.146.11.74]) by newsunmail1brm.central.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id m9VDEo9J056824 for <@sunmail2sca.sfbay.sun.com:PSARC-ext@sun.com>; Fri, 31 Oct 2008 07:14:50 -0600 (MDT) Received: from pmxchannel-daemon.nwk-avmta-1.sfbay.Sun.COM by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0K9L0040BU4PRF00@nwk-avmta-1.sfbay.Sun.COM> for PSARC-ext@sun.com (ORCPT PSARC-ext@sun.com); Fri, 31 Oct 2008 06:14:49 -0700 (PDT) Received: from dm-east-01.east.sun.com ([129.148.9.192]) by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0K9L004D8U4NJI00@nwk-avmta-1.sfbay.Sun.COM> for PSARC-ext@sun.com (ORCPT PSARC-ext@sun.com); Fri, 31 Oct 2008 06:14:48 -0700 (PDT) Received: from [129.148.226.11] (sr1-unsh01-01.East.Sun.COM [129.148.226.11]) by dm-east-01.east.sun.com (8.13.8+Sun/8.13.8/ENSMAIL,v2.2) with ESMTP id m9VDEhwa049244; Fri, 31 Oct 2008 09:14:43 -0400 (EDT) Date: Fri, 31 Oct 2008 09:14:42 -0400 From: Brian Utterback Subject: Re: tftpd server maximum timeout [PSARC/2008/652 FastTrack timeout 10/30/2008] In-reply-to: <200810231837.m9NIbCm5010948@sac.sfbay.sun.com> To: Brian Utterback Cc: PSARC-ext@sun.com, Satish.Murugesan@sun.com, Sreedhar.Chalamalasetti@sun.com Message-id: <490B04C2.8000209@sun.com> MIME-version: 1.0 Content-type: text/plain; charset=ISO-8859-1; format=flowed Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <200810231837.m9NIbCm5010948@sac.sfbay.sun.com> User-Agent: Thunderbird 2.0.0.18pre (X11/20081021) Status: RO Content-Length: 3083 This fast-track was approved at Wednesday's meeting.
