I would like to know if there are any toturials or if someone can write one.. (or give some tips) of how can i secure a machine running FreeBSD and used for irc + shells!
For example how can i install a firewall, a rootkit etc etc..
Also what about putting users at jail? (not allowing them see other dirs except theirs) how can i do that?

View 6 Replies View RelatedI am having some server issues.
A part of my sshd_config:
Port 2255
Protocol 2
ListenAddress 8x.xx.xx.46
PermitRootLogin no
Recently, when I want to connect to my server using putty, I get "Connection Refused" using the above IP address and port.
When I enter the above IP address (or any other IP address that is stored/set on the server) and port 22, I get "Server refused to start shell/command".
It did work before, using 8x.xx.xx.46:2255 and when I enter 8x.xx.xx.46:22 it will block. But now... not anymore.
I am using "Direct Admin" to do a "System Backup". I do see the right port and IP address in the sshd_config file.
How can I fix this? I can not login the server anymore, however I am going to the datacenter tomorrow.
OS: CentOS
Installed firewall / protection: APF + BFD
Control Panel: Direct Admin
I have write up a simple shell script from my windows desktop.
After i upload the file via ftp and run it as root, it doesn't run properly.

my server in under attack of shell
how can i find shell code in my server? (c99 ...)

how can i disable shell function?
I have spare dedicated machine.
I want to allow user to run few processes on machine (debian etch).
I configurated limits at /etc/security/limits.conf for group "shell".
When I attached user to group shell, limits work well, but he still can look
everywhere on system. (he can do cat /home/somefile.txt, even owned by root).
Is there any method, software to limit user to acces only their home directories?
For security reason I have these php functiosn disabled:
show_source, system, shell_exec, exec, popen, proc_open, procopen, passthru
Can anyone please tell me whether if it will prevent shell scripts from working?
They can still upload the shells but cant read/write/execute commands in 777 directories?
I'm having a problem connecting to SSH/Shell on my server. I get the Login Prompt, but when i enter the User/Pass i just get "SSH-2.0-OpenSSH_3.6.1p2", everything under that is blank.
I've restarted the SSH Server and made sure the account i was using was set to use Normal Shell (not jailed). What could be the problem?
I was wondering if it were possible to chmod a directory that is set to a low number to 777 using a shell or command and if so can anyone point me in the right direction as to how to go about doing so ??? I am trying to learn a little and i pefer using my browser to edit files rather then a ftp client.

View 5 Replies View RelatedI'm trying to program a very simple shell script that does 2-3 things.
1) checks for the number of a script running say, "ps aux | grep php | wc -l" returns that number.
2) deletes temp files folders "cd /to/that/directory/; rm -fr *&" every 90 seconds IF that number in check #1 is below say 50....
and then have this shell script launched in shell every so often, not sure on the frequency but first is how to program in shell is a TIME DELAY....
We have customer who has account on our *nix box server and who wanna move to our h-sphere reseller platform because now he want to use asp and mssql.
If it`s .com domain, for example, I would be able to easy change NS1 and NS2, but since this is ccTLD (and we will wait 10-15 days) I need quick solution for DNS forwarding.
ns1.oldnameserver -> ns1.newnamerserver
ns2.oldnamesrever -> ns2.newnamerserver

View 1 Replies View RelatedI've enabled ssh one of my account in WHM, so I went to cpanel of this account and tried the SSH/Shell Access, but what I got is:
For security reasons, shell access is not enabled by default. In order to activate shell access on your account, you will need to fax or mail a copy of your driver's license, passport or other photo id to customer service.
is this something about SSH Key? do I have to generate a key so I can use the SSH/Shell Access?
On a VPS I am using, I was astonished to see that when I login through SSH to a WHM account, I can go right up to the VPS system directories, do an ls, read the files etc. the user is able to get into the all the VPS directories, except root.
It's fine in FTP. Although I can see the link to the directory above home, clicking on it does not take the user to those directories.
When I ask my service provider, they say, "Yes, this is normal behavior. The users will still be able to move into the other users' home directories but they will not be able to write to the files or open them".
It seems to me this isn't a good situation. How can I prevent shell users from going beyond their home directories? Is implementing a jailed shell a good option? Can I use this feature that is readily available in WHM?
I'm trying to install the following portwatch script on my server to count the # of connections coming from various IPs:
