...version which prompted me to release 2.3.1 today. I will announce that separately in appropriate channels. Please upgrade to the 2.3.1 release, not the 2.3.0 release. Max Vozeler reported a flaw in the design of rssh_chroot_helper whereby it can be exploited to chroot to arbitrary directories and thereby gain root access. If rssh is installed on a system, and non-trusted users on that system have access which is not protected by rssh (i.e. they have full shell access), then they can use rssh_chroot_helper to chroot to arbitrary locations in the file system, and thereby gain root access. Workaro...

...art of a bigger effort to port the ISOLINUX hybrid mode to ReactOS, I've encountered a bug in isohybrid under Windows platforms. Attached comes a patch to fix it. Precisely, if isohybrid currently finds a 0x0A (LF) byte in the MBR code (which exists in the strings), it adds a 0x0D (CR) before, thereby shifting the MBR bytes to the right and making it invalid. This can be fixed by opening the file in binary mode with the "b" flag. Cheers, Colin -------------- next part --------------

Folks I have a laptop which i am using temporarily as a test server. It is permanently plugged in. It is running Centos 6, command line only. In the past, I could close the lid, thereby turning off the display, but not turning off the machine. It remained running indefinitely. A recent update (this past week) changed that behavior. Now, when I close the lid, the laptop turns itself off within an hour. A google search talks about tools like "upower" and apcitool, bu...

I would have thought that the IMAP Append command would *save* bandwidth (as opposed to having the client save a copy to the Sent folder, thereby uploading the full message a second time). I want to revisit this with Timo, because there was supposedly a pretty simple way that we could achieve the same thing that gmail does - auto save all sent messages to the designated Sent folder server side, thereby allowing us to disable the 'Save t...

...ing how this is supposed to work. I have written this ".iso" image to a DVD and booted from it. I then selected the first install option from the menu. I get some prompts and then I'm asked to specify where the media is. I assumed (there's that word) that I should just hit enter, thereby selecting the "from DVD" option. I got a message about not being able to find the install materials? Is this what the install process is looking for? Shouldn't it be looking in the network? Can anyone see what I'm doing wrong? Thanks, George...

We''re running a handful of XCP 1.1 pools and have run in to situations wherein the local filesystem on the Dom0 control domain hits 100% capacity due to error logging in /var/log (daemon.log, messages, xensource.log, etc) thereby taking that host offline. Twice recently we''ve run in to this, on two different pools, first due to the primary SR hitting capacity and secondly when memory was exhausted on the host. My question is, how do others manage logs and such under these circumstances on Dom0? The first obvious...

...tring.rand(15)) self.otp = Digest::SHA1.hexdigest(Time.now.to_s+"_"+String.rand(15)) self.verified = false #logger.debug("--> "+self.to_s) #This is the magic line!! end The really really black magic part is that, if I comment the logging statement in, and thereby call self.to_s, the user record gets added. Can anyone come up with a somewhat rational reason for this behaviour? Thanks. Morten

...tarted using the "ccf" function (part of the "stats" package version 2.16.0), about which I have a question. The "ccf"-algorithm for calculating the cross-correlation between two time series always calculates the mean and standard deviation per time series beforehand, thereby using a constant value for these irrespective of any time-lag. Another piece of statistical software that I'm using, a toolbox in Matlab, does this in a fundamentally different way. It first "chops off" the parts of the time-series that do not overlap when a time-lag has been introduc...

Hello, All: What would it take to make ?iconv? portable? I ask, because I want to convert accented characters to vanilla ASCII, thereby converting, e.g., ?Ra?l? to ?Raul?, and Milan Bouchet-Valet suggested on R-help that I use 'iconv(x, ?", "ASCII//TRANSLIT?)?. This worked under Windows but failed on Linux and Mac. It?s part of the ?subNonStandardCharacters? function in the Ecfun package. The development version on...

After upgradeding to bareos 15.2, which also has a web ui, thereby making it usable (since the command line tool, bconsole, does not have a paging mechanism, and its sytax for choosing files to restore is, let us say, arcane), I've got another question: is *anyone* using bareos with kerberos? I see that they have in alpha(?) tls support, which isn't a grea...

In my layout I have a navigation bar with a few elements in it. The elements can be toggled on or off and thereby reveal or conceal some subtopics. I store the state of the toggle for the navigation elements in the session. When the page is reloaded, the navigation items are collapsed because the css for display: none is set by default in the html for the navigation elements. Is there a good way to pull...

Hi does somebody know how to plot single letters in a text in different colours? example 1: I would like to add the word "ABC" to a figure. Thereby each letter should have a different colour. text(x,y,"ABC", col=c(1,2,3)) # this does not work example 2: I would like to add the name of a parameter p with an index i to a figure. The index i should be in red, whereas the rest of the text should be in black. text(x,y, expression(p[...

...inux. We can do this, either commands of Samba - smbmount - or with Komba2, that we've installed. But, we can't mount resources from Windows 2000. There is a machine with these operating system and with a firewall installed. But, these machine doesn't receive petitions from our samba, thereby the firewall never contests something. For other side, we go on without can see our PC over the net. We mean, to see our Samba from PCs with Windows. We don't know what happens!! Somebody can help us!! Thanks

...pected) Fisher information matrix for parameter estimates in a rather complicated setting. I thought I had it working, but I am getting a result which is not positive definite. (One negative eigenvalue. Out of 10.) Is it the case that the observed Fisher information must be positive definite --- thereby indicating for certain that there are errors in my code --- or is it possible for such a matrix not to be pos. def.? It seems to me that if the log likelihood surface is ***not*** well approximated by a quadratic in a neighbourhood of the maximum, then it might well be that case that the observed...

...populated into the rsync module, appearing ultimately as server::image/etc/init.d/script, but we don't know ahead of time which scripts will show up. When we issue the above commands, rsync removes the /etc/init.d directory altogether, and recreates it with only the scripts in the module, thereby removing all of our existing init scripts. [We have checked, and the inode number for /etc/init.d changes.] This is not the desired behavior - what we want to do is add the contents of the module to our existing files, without removing any of them. When we simplify the command line down to rs...
