I was doing some experiment about resource-accessing. By mistake, I executed this command,$ sudo mv /etc/passwd /etc/passwd.bakThen I could not execute any command with privilege(eg. sudo mv /etc/passwd.bak /etc/passwd). When I shut the system down, I could not boot it any more.
View 2 Replieswe know that /etc/passwd - is a replica of /etc/passwd file and acts as a backup in any damage done to /etc/passwd file..i have observed a strange thing in RHEL 5.4....for example... if /etc/passwd has 100 accounts.. then /etc/passwd - is having only 99 accounts....when i add 101 useraccount with "useradd" then /etc/passwd has 101 accounts and /etc/passwd is having the 100th account of /etc/passwd - ..when i delete /etc/passwd and recover it with /etc/passwd - from runlevel 1 the lastly created user is not having his account after recovery.. what is the solution? this is same case even with /etc/shadow and /etc/shadow -

I have a Debian 5.0.7 installed to my server. I try to install Apache and SVN to this server. I use this tutorial: http://www.howtoforge.com/subversion...-ubuntu-server
But is unfortunately not working.
My apache virtual host configuration file is:
Code:
This passwd file containing 1 user:

The rights for the passwd file:

And apache2 is running like this:
Code:
And if I try to login to my page I got an "Internal Server Error" page.
And my error is in the apache log is this:

So I'm a little bit confused about it. The apache2 should have rights to open this file. I checked it, the file is exist and the apache2 is have rights for it. I don't understand it.

View 4 Replies View RelatedI work for a seismic company that has recently experienced a security issue. Because we have an isolated network that is used for HPC work we have a very open security structue ie password less accounts rsh rlogin etc. We had, seemingly,a user that has maliciously deleted another user's files but I still haven't figured out how. So far I have been able to prove that this user has remotely logged into another host under that user's account... or at least that their workstation did. The /var/log/message file shows logins from their workstation as that user multiple times durring the times that these files were being deleted. There are wildcard searches for these files in the history in this host. There is a vi session initiated on this host for a file called delme (delete me) and then a chmod +x for this file. and then a deletion of this file (rm delme). Funny things: this user has no business in this acct. this user was bounced off the other host (permission denied) when trying to log into the other host and then as root logged into the other host as the other acct. repeatedly... ie. rsh -l xxx (permis den) then as root rsh -l xxx (logged in) why not su xxx and then rsh? password less acct?! why use root privs (which they sholuld not have) to log into a passwd less acct? Can't see any remote logins to their workstation from elsewhere. can't find smoking gun. no execution of delme script or any other rm /*/xxx/* sort of command that proves when file deletion of striped files happened?!
changing root passwd soon.need proof that no remote logins to a CentOS 5.3 workstation could be responsible.
Could mean someone gets fired.how can I be sure that no other users logged into this machine and then into another machine for sure?

View 4 Replies View RelatedAll servers mentioned below run OpenSuSE, either 10 or 11.I am currently working on a few scripts that are meant to be used as part of a continuous integration setup. I am trying to keep these scripts reasonably secure, and so I have made sure that all the servers run these scripts only as a specific user (user1) that has permissions to basically nothing else. The problem I am currently running into is that I need to start and stop tomcat as user1 but this user doesn't have permissions to the tomcat rectory (only tomcat has execute permissions). I have a temporary workaround in place while I work on the scripts (I have an SSH key in place that allows me to SSH from user1o tomcat without a password and execute my commands that way) but it is not very secure. I have tried adding the following line to /etc/sudoers:
Code:
tomcat localhost = NOPASSWD: /opt/tomcat/bin/startup.sh, /opt/tomcat/bin/shutdown.sh
but it doesn't work as I expected it to. I tried a few different syntaxes for that line,

I'm running a small network of 20 PC's (slackware), I had previously used NIS and can't really be bothered with ldap it's a bit of hassle. I do not need a centralised database just a login auth system.On the server I make a folder called /sec and symlink passwd, group and shadow into it.I export this via nfs.On the workstation I create a folder /sec, move the passwd, group and shadow file into it and then symlink them back into the /etc folder.On bootup, the rc.local mounts server /sec over the top of workstation /sec. If it fails it falls back.I wasn't sure if I could just mount /sec on the workstation and then temporarily symlink group,passwd,shadow over the top of the /etc/shadow etc
