Hi I am writing a python test suite that uses oz (https://github.com/clalancette/oz) which uses libquestfs. I am simulating a small cloud and have some apps that need to talk to the guests. All works really well until I needed to start another process. So I start a process then "oz" starts up a VM (it uses libquestfs) then when "oz" cleans up it calls

...ny systems are configured so you cannot log directly as root via the initial authentication in openssh. What is usually done is that you log onto as your normal login and once you get a interactive shell you su to root to run the command that requires root. Does openssh have a more elegant way of exec'ing a command as root so I can run the command non-interactively?

- add a flag to request chroot for the process, which is done only as very last (before chdir) operation before exec'ing the process in the child: this avoids using CHROOT_IN & CHROOT_OUT around command* invocations, and reduces the code spent in chroot mode - add failure checks for dup2 and open done in child, not proceeding to executing the process if they fail - open /dev/null without O_CLOEXEC,...

Hi , I am using OpenSSH4.3p2. One of the fixes in this release says that random seed generation is not necessary for each key generation and initial seed will be served for the re-exec'ed processess. As better random seed will yield better random number generation, how can we achieve true randomization by one time random seed ? Thanks, Ponraj M

...;s format from one ssh implementation to the next varies, causes parsing complexities. Tried a kludge using the "command=/some/path/to/script <ID>" prefix on each key, where the script took the ID and logged it along with some of the other ssh variables. However that meant either exec'ing the command being sent from the remote system, or forcing the session into a specific shell. Is there any other way to determine what key is used?

Here's a simple patch which retrieves authorized_keys via exec'ing a program, rather than reading a flat file. I added a simple option, AuthorizedKeysExec, to sshd_config which simply executes the respective file, passing the username as argv[1]. Keys are returned via stdout. Notes: If AuthorizedKeysExec is set and an authorized_keys file exists, che...

John, Thanks for the quick reply.  Using a PassManager object should work fine.  As you said, my only objection is to exec'ing opt.  I had actually tried instantiating a PassManager object before, but I was definitely not doing it right.  I will take a look at how clang and SAFECode use it, and see if I can get it working. Thanks, David ----- Original Message ----- From: "John Criswell"...

hiya. i'm using ices 0.2.2 with icecast 1.3.10 and otto 1.0 (a web/db playlist mgmt tool). overall, i'm very pleased with the setup, but i'm having a few problems. 1) whenever otto plays a track (by exec'ing ices), that same track keeps playing over and over. i have to direct otto to kill the track (and the ices process) in order to get it to play the next track. i notice this comment in the source for ottojockeyd (the program that actually execs ices): # note: you may need to hack the ic...

I am running the following llvm-ld command to produce native code: llvm-ld -native -o code.exe code.bc -lm However, I am getting the following assertion failure in llc. The bytecode has been processed with opt, it passes opt bytecode verification. I'm not too familiar with backend code generation. Does anyone have any insight in to what the problem might be or how to go about

...prudentrx.com -n -x "Test fax" -d 13105551212 /etc/hosts fax": Can not open file As you can see the sendfax command is not picking up the "'s around the "Test fax" string so it picks up the Test but thinks fax is the file to fax. If you take the string and execute it from the command line it works. There is something about executing it from a string within a script that causes it to fail. I tried doing the same thing using mail as the command with a quoted subject. Same thing happens, it break after the first space in the subject when executed fr...
