OK, I'll consider to add a new flag for tftp.

Two other flags that will most likely cause us problems that xcat version doesn't have, -p and we -r blksize. We also explicitly limit (-s) to /tftpboot. if I use -u and -s basic tftp sends do work, but that won't be enough. I don't necessarily need it run by xinetd, though, another possibility is something like a tftpflags entry on site table for peeps to modify syntax on tftpd start... _________________________________ Douglas Myers, IBM Special Events - Smart Cloud BMS Lead _________________________________ "It's not an opportunity if it doesn't scare you a little bit" Inactive hide details for Xiao Peng Wang ---09/11/2012 07:26:03 PM---From 2.7, only the tftpd which shipped with OS with be useXiao Peng Wang ---09/11/2012 07:26:03 PM---From 2.7, only the tftpd which shipped with OS with be used.

So that means no XCAT tftpd is installed, the tftpd shipped with sles11 will be used. Your description of the procedure that configure the tftpd in xCAT is correct. There's a long story for the tftp configuration. At first, xCAT uses the xinetd to control the start of xcatd, but found a defect that the 'alias interface" could NOT be handled with xinetd. Then xCAT changed to start the 'tftpd' directly from shell. To answer to both of your questions is 'NO'. Maybe we could add a switch in site table to disable it. One question to you that what's the problem you mentioned that tftpd started by xcatd. xCAT team will try to recreate this issue and fix it.

Upgraded from 2.6.6 to 2.7.4 and working through some of the results. The first and most major we have seen is the new way xCAT handles tftpd. I noted that restart of xCAT removes our xinetd tftpd cfg file, replaces it with one of it's own, then disables it. xCAT then seems to start a tftpd outside of xinetd. However, the instance xCAT starts isn't working, and doesn't have the syntax we want, and really, we'd rather have xinetd handle (for auditing purposes). We cannot get a successful statelite boot with the xCAT tftpd, once we put back our xinetd tftpd file and start it up, we start seeing normal behaviour. Note also that we never used the xCAT provided tftpd rpm, but always removed it and added back in SLES tftpd rpm. Two questions then: 1) can we disable the xCAT tftpd overtake process? 2) Is there some way to modify what syntax xCAT calls on tftpd? _________________________________ Douglas Myers, IBM Special Events - Smart Cloud BMS Lead _________________________________ "It's not an opportunity if it doesn't scare you a little bit" ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
