View 1 Replies View RelatedI've scanned my computer (I'm using Ubuntu 8.04 Hardy Heron) and ClamAV has issued it has found a virus called Exploit.PDF-9669. What seems strange to me is that such a warning always happens (or, at least, in the most cases) in the same folder tree "sys" and ClamAV issues the very same virus/malware warning (Exploit.PDF-9669).
An example:
sys/devices/virtual/vtconsole/vtcon0/uevent: Exploit.PDF-9669 FOUND
sys/devices/virtual/net/ppp0/address: Exploit.PDF-9669 FOUND
sys/devices/virtual/net/ppp0/broadcast: Exploit.PDF-9669 FOUND
sys/devices/LNXSYSTM:00/device:00/uevent: Exploit.PDF-9669 FOUND
My ClamAV version is 0.94.2/10275/Fri Jan 8 22:06:46 2010. It has been not updated since I installed Hardy in my computer last year. Is my computer in danger?
I am having a weird problem here. The open programs are closing secretly without giving any indication or issuing error. For example I open couple terminal and some minutes later I look at my screen, boom they are not there anymore. This issue is not just limited to terminals, other gui apps suffer from the same thing. Does anyone know if any program or service would do such a thing?. I am scratching my head here to figure out why that is the case It just started happening today.

View 1 Replies View RelatedBash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.

View 4 Replies View RelatedUp until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else
