Hi all, I experienced the same problem with 3.0.4 that Jeremy and Bruno were discussing - NTBackup unable being to connect to shares and erroring out with 'Access Denied'. I have today upgraded to 3.0.5 (using the Debian Woody packages) and that didn't fix the problem. Was the fix in 3.0.5r1 only applicable to 2000/2003 server? I am stuck in the dark ages of NT 4 here, maybe that is a

hi, i created a share called backup and it is wrightable for everyone but even so the windows gives me the access denied when using windows backup but i can acess normaly and create using windows explorer any ideas? using win2k

Hi, You can use the projectLinear argument in BB::spg to optimize with linear equality/inequality constraints. Here is how you implement the constraint that all parameters sum to 1. require(BB) spg(par=p0, fn=myFn, project="projectLinear", projectArgs=list(A=matrix(1, 1, length(p0)), b=1, meq=1)) Hope this is helpful, Ravi [[alternative HTML version deleted]]

Hi Folks, Prompted by this talk of ssh-import-id, I am reminded that Eric Moret and I have collaborating on a new version of ssh-copy-id, available here: http://git.hands.com/ssh-copy-id Recently, Eric and I have been taking turns to be too busy to test the very latest stuff (mostly my fault), but I think it's now pretty much ready for a wider public, and if it's n...

While I was updating our ssh-servers, I rewrote my old patch that adds idletimeout (just like in old ssh1) parameter to openssh. Since reapplying the patch for all new versions of openssh is not fun at all, I would like to have it included in the official openssh, if you consider the patch worthy. Unlike ClientAlive, idletimeout works for both protocol versions. It also works together with

Hi! when using agent forwarding, the connection hangs on exit, if the agent has been accessed. Symptoms: - On the client side, when the agent is accessed, the following output is being logged: debug1: channel 1: new [authentication agent connection] debug1: confirm auth-agent at openssh.com debug1: channel 1: rcvd eof debug1: channel 1: output open -> drain debug1: channel 1: obuf empty
