chkconfig issue

rsheikh · 02-14-2012, 06:10 PM

Hello, I did a search in the forums for chkconfig but did not find anything.

System is RHEL 6.1 (32 bit), execute as root

Quote:

chkconfig --add ./sas.servers
error reading information on service sas.servers: No such file or directory

Google and other did not yield much, any insight is appreciated.

Note: the second part of the command I will execute once the --add works.
chkconfig --level 35 sas.servers on

First, the service needs to be located in /etc/init.d/ in order to be properly managed.

Second, you should read the RUNLEVEL FILES section of the chkconfig man page.

Once you add the required chkconfig comments to your init script and it's located in /etc/init.d/ folder then the chkconfig --add sas.servers command will work (not ./sas.servers) and you can manage the service using chkconfig.

Other man pages you should look at on your redhat system include:
man chkconfig
man service

You're a Wizard, Harry! Yes that was my mistake, thank you for the suggestion and guidance sag47. Devilboy, I was trying to do what sag47 suggested. I appreciate both of yours time!

SAG47, I just saw in your profile that you have WIN X64 as well as are a linux expert. One question if I may please. Unrelated but I have been trying to communicate from a win64 7 pro to rhel 6 machine, hosts.deny and hosts.allow all commented out, sshd is running, but I keep getting connection refused, or when I run portQry form the windows side for a particular port (that port on rhel is listening (netstat -an|grep 8561) I get FILTERED status from PortQry. On WIN machine I turned off the firewall (for testing) also added PortQry in allow through firewall, no third party firewall running) but no resolution. MS tech support said it is RHEL that is refusing.

I will do the homework and reading but please if you could point me to where I should start looking, I am going nuts!

clearly, there's something wrong on your linux machine.is you firewall off on that machine?

I run a mixed environment at home which is why you see Windows (for games).

It is likely being filtered by iptables (comes by default in RedHat) like devilboy suggested. What is the service you're trying to access over 8561? If it is ssh then check the service status for sshd running.

Code:

service sshd status

Also see if you're able to hook the service banner from ssh on the machine as well. From RedHat run,

Code:

telnet localhost 8561

If it returns with your ssh version and other minimal information then it is properly listening and likely the firewall (iptables).

The configuration file for iptables is located in /etc/sysconfig/iptables. You can find extensive documentation on iptables at netfilter.org. Here's possibly a good starting point for you to start researching. These rules were generated on a debian machine I administer (some modified) but it will give you a decent idea.

Code:

# Generated by iptables-save v1.4.4 on Wed Sep 28 08:51:40 2011
*filter
:INPUT ACCEPT [388:68427]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [196:19118]
-A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT

#allow ssh over port 22
-A INPUT -p tcp -m tcp -m state --state NEW --dport 22 -j ACCEPT

#allow ping machine
-A INPUT -p icmp --icmp-type 8 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

#localhost gets everything
-A INPUT -s 127.0.0.1 -j ACCEPT
-A OUTPUT -s 127.0.0.1 -j ACCEPT

#End of rules, drop everything else

-A INPUT -j DROP
-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7

Keep in mind those rules may not work for you on your RedHat system but it gives you a general idea from which you could take. Also those rules allow the world on those ports. You should filter ip addresses by using the -s (source) option.

You can do this, albeit arguable to do so.

But if you do, than use for each and every file used by this server with absolut pathes.

Thank you again, you folks are very kind people. Yes sir, I looked in enough google articles to look if sshd is running (it is). I came across someone's IP table rule, hate to admit went over my head. But I will start looking. RHEL and WIN are both inside my LAN. I do not access internet through them (that does not mean someone could not come in). It is a statistical application which is listerning on 8561 (installed on rhel machine). I was trying to have the web application server (jboss-GA) run on win7. That is where during install, it could not see the rhel machine (where app's metadata service runs).

I will start in the direction you suggested.

Again, heaps of thanks
