View 7 RepliesI'm trying to start an Oracle Integration server as user "oracle" at system startup and my approach was to place a couple of lines in /etc/rc.localsu oracle/home/oracle/startallSomething is not quite right about this as it seems to leave some processes owned by root.
View 2 Replies View RelatedIn the past, I've installed Internet services as daemons and as xinetd.d with no problems. Those approaches do not meet my needs. And, perhaps, nothing will.
- the service was converted from VB-6 to wxPython. It has a GUI which is accessed with either "remote desktop" or VNC.
- the wxPython service works on Windows and can be accessed from other hosts on my LAN
- the wxPython service works on CentOS and Fedora, but can only be accessed from within the server host. Even from other user-ids. But, I cannot get to it from other hosts.
- ipchains AKA firewall ports are marked for INPUT.
- The server host uses autologin to fire up a useid in group "user". I do not want it running as "root". the .bash_profile fires the service up.
- the service is heavily mult-threaded, and supports devices connected to serial ports asynchronously with the ephemeral port threads (all this works).
There are some programming solutions that I would rather not develop.
- a proxy service that runs under xinetd.d.
- separate the GUI code from the Internet and serial port code. Allocate a "control" port for remote GUI control. a'la SAMBA & SWAT

I'm trying to get vsftpd running with both anonymous and local user access to the same folder. The directory I'm using is /tftp with the following permissions:
dr-srwxrwx 7 root root 12288 2009-08-14 15:54 tftp
My vsftpd.conf is this:
anonymous_enable=YES
local_enable=YES

I set the default "ftp" user's home directory to /tftp (was /var/ftp).
I have a dynamic Internet connection. My eth0 is configured to DHCP client. I need to rum one personalized command all time the dhclient renew the lease. I have a program that update the /etc/hosts with the new IP and I need to run this command when dhclient receive one lease update.

View 3 Replies View RelatedI've got used to using the ftp command from the terminal, which is useful, especially with macros. But it requires user input, and what I want to do now is upload a specific file to a server, once I've finished working with it every day. It's the same file every day. II would like to be able to do this semi-automatically: I just give the command and it connects to the server and uploads the file. (I will probably want to encrypt the file before uploading it.)I don't know how I could use ftp without any user input: I want it to be automatic.

In Karmic, I could run an app as user gdm by issuing the following command (assume the app is gconf-editor)
Code:
gksudo -u gdm dbus-launch gconf-editor
Now that I've switched to Marverick when I issu the same command I get this:
Code:
towheed@GA1A4CH:~$ gksudo -u gdm dbus-launch gconf-editor
No protocol specifiedNo protocol specified
** (gconf-editor:19812): CRITICAL **: Failed to parse arguments: Cannot open display:
I checked my environment variable DISPLAY using:
Code:
towheed@GA1A4CH:~$ echo $DISPLAY
and it returned:
Code:
:0.0
Now I ran the command:
Code:
gksudo -u gdm dbus-launch gconf-editor --display=:0.0
and got the same error as before.Has either or both dbus-launch or gksudo changed their behavior os is this a bug. Note that the command does not work with any applications being run as the user gdm.
Is it possible to allow a group/user to execute a command, where one of the parameters of the command is a group as well? example that does not work as intended:
Code:
Cmnd_alias SU=/bin/su -l %group1 This example works sortof, it treats the "%group1" literally. I know I can list out the "/bin/su -l <eachuser>", but as you can imagine that is impractical. In this example, I want people in group2(not shown for brevity sake) to be able to su to someone in group1
I have a weird question about the sudoers file. Currently, I am running "Red Hat Enterprise Linux ES release 4 (Nahant Update 8)".
I edited the sudoers file (via visudo) and added the following:
User_Alias RPTS2 = vtmtest
RPTS2 xxxxx = (jboss) /oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
The user (vtmtest) issues the following command
sudo /oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
and gets this message:
user vtmtest is not allowed to execute '/oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh' as root on xxxxx
When I look at the log, I see the following:
Jan 25 14:17:57 xxxxx sudo: vtmtest : command not allowed ; TTY=pts/12 ; PWD=/export/home/vtmtest ; USER=root ; COMMAND=/oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
1. Why does sudo try to run as the root user, when I have specified in the command to run as jboss?
2. Do I need to specify anything else so that this command can run as the "jboss" user and not "root"?
I have an existing quota setup which works fine for 2 users.

I'm a web developer and I make plug-ins for various shopping cart softwares on demand. because of this I'm constantly installing carts and then immediately updating them/modifying them. The problem I'm having is that I'm having to update the permissions manually all the time (every time I copy a new cart into the /var/www folder). Instead of doing this I'd like apache2 to run under my user, so I don't ever have to update the permissions again. How do I do this?

I find myself in a bit of a pickle. Following a yum update which included FF 3.0.8 FireFox stopped working details can be found in Fedora Bug 494255.

I figured all I needed to do was put a link to libflashplayer.so in /home/user/firefox/plugins/ and we'd be good but when I go to a site with flash content FF crashes. I installed Leigh 123s X86-64 flash rpm and made a link to it as above and got the same result.

View 13 Replies View RelatedI've written an article on my site which lays out steps for installing Wine and running it under its own, separate user account, so that Windows applications cannot access personal files (particularly those in your home directory).[URL}..i'm hoping that there are people on this forum who know Ubuntu inside-out, as I'd like to know how effective the described method is at trapping Windows applications so that they cannot read or write personal files or directories.
The way I understand it, once the process is running under user account wine, it's stuck with the access privileges of user wine. But are there ways in which a rogue application could break out of this prison and gain access to whatever it wishes? I'm guessing that such behaviour would mean someone customising Windows software to recognise Linux, and that such a thing is very unlikely, but I'm still interested to hear what gurus of the Ubuntu internals think of this method.
is there any possible way to hide currently running processes from an user? This means I do not want him to know about what programs/processes does any other user but him run. In short words if that user runs 'ps -aux' he should get only his processes.

View 1 Replies View RelatedI'm trying to get Apache to run in a user's home directory. I changed the conf file so that Apache runs under the user and group "kiosk" and changed the DocumentRoot and Directory from the default to "/home/kiosk". Then I set Apache to start at boot (chkconfig --level 235 httpd on) and rebooted. When I checked, httpd is running as kiosk like it should (ps aux | grep httpd). However, when I try wget localhost, I get a 403 response back. If as root I call "httpd -k stop" and then "httpd -k start", then everything works exactly as it should (curiously, if I try using "-k restart", it still doesn't work). After this, httpd still shows as running as kiosk and if I check before calling start, it shows no httpd processes running as expected.
This only happens when I use httpd to stop and then start the web server. If I try to restart using apachectl I still get a 403 error. As an interesting aside, after I've used httpd, if I try using "apachectl restart" I get a "(13)Permission denied: Error retrieving pid file run/httpd.pid" error. This is all on a freshly installed CentOS 5.5 server. Why I'm seeing this very different behaviour from what I thought were just equivalent ways of starting Apache? And then what I could do to get it to start up and run properly on boot? One last item to mention is this isn't a permissions problem. I set the permissions to 777 to both the home and kiosk directories (and 666 to the web files) just to be sure that's not the problem.
Take a simple requires-root option, such as:
Code:
[Leo@chessman ~]$ cat /etc/shadow
cat: /etc/shadow: Permission denied

When I run set | less as a user, my root password is displayed in the last line of rules.
Code:
_=su
