Hi, I have written a backend for creating ftp-users for proftpd via MySQL-module. After deleting a user from database some OS-specific tasks are left: deleting or moving the files of the user on file system level ("rm -R /home/dir/of/deleted/user"). The backend runs under linux user A, the ftp root belongs to user B. Therefore and for ...
Hi, I'm trying to automate some debugging tasks. In certain cases, I print the value of $ra [this is a MIPS machine] and parts of the stack as hex addresses. During debugging, I use addr2line to convert them into file:line pairs. I'd like to automate this procedure. The problem is that addr2line returns a filename that equivelent to t...

Unfortunately I cannot recall how to do this, or where I read it. Can anyone shed some light? Update0 To refine my query, I'm after the same blocking and guarantees th...
Hi everyone, I created a fuse mountpoint. After mounting, the file permissions are all screwed up and it says I cannot ls or cd. Permission denied. The file permissions look like this: d????????? ? ? ? ? ? temp and when i list the mounted devices I get: /dev/fuse on /temp type fuse (rw,nosuid,nodev) I used mono-fuse. I just created a...
gI've compiled the kernel to support USB HID and keyboard devices. When I plug in the USB keyboard, the kernel recognizes it, and goes so far as to latch/unlatch the NUMLOCK led when I press the same key. Is there a dev file entry I can create so I can read (cat /dev/input/...) data from the USB keyboard? I appreciate that I might be l...

What is the MD5 Fingerprint field before the PEM data of a CA cert in ca-bundle.crt used for by consuming applications? When I enter the hash incorrectly, I find that I'm still able to use openssl to start a TLS session with a server whose cert is signed by that CA. Example: American Express CA MD5 Fingerprint: 1C:D5:8E:82:BE:70:55:8...

Would anyone know what the...

Just like a "net send" on Windows, if I remember what net send does correctly. I just want to say something like: <command> <IP address> "Hey what's up?" and the message "Hey what's up?" should show up on the other guy's machine. Ideally this shouldn't require installation of any packages not already present in typical UNIX/Linux dist...
