Sorry but I'm a new user and would like to know how to enable/disable firewall. I have tried to open a port up on my firewall but, for some reason that didn't work. I have found these command in another thread: $ sudo /sbin/chkconfig iptables off $ sudo /sbin/service iptables stop I assume this is to disable the fire wall. How do I enable it once I'm finish running my program.
I'm looking for some definitive instruction on the proper way to enable/disable (not to simply start/stop or add/remove packages) services/daemons under Debian 6. Google results are all over the map and, surprisingly, the Debian wiki has no abstract on services.It seems like such a common task
Chkconfig is a utility to update and query runlevel information for system services. Chkconfig manipulates the numerous symbolic links in /etc/init.d/, to relieve system administrators of some of the drudgery of manually editing the symbolic links.
In Debian, there are several tools with similar functionality, but users coming from other Linux distributions will find the tools in this package more familiar.
Go to Terminal and open it and type the command "chkconfig' press enter. code...
after installing just type "chkconfig" you can see list of service which one is off or on in your system code...
I was running NFS in my Fedora. I found that I could not mount exported directory in client machine (Fedora ) with firewall enable in NSF server. Even I tried by clicking out all services in firewall (but not disabling it), it did not work. To make it work, I had to disable firewall. Is there any way to do this without disabling firewall?
Sent an email by using telnet on port 25 from the terminal. Telnet states my message was sent but I never got it. Is it on the hard disk somewhere. Is there a log file? Where did my email go? Did it go into the ehter? I opened port 25 on my firewall through gnome by selecting 25/smpt checkbox as a trusted service.
I'm working on setting up access for our developer via Telnet, we are on a local network behind a physical firewall. I set up the standard Telnet service for Fedora15 and from localhost I can login via any user and root.... However I cannot login from another terminal on the LAN, even though I can ping and FTP to the fedora15 box. I added the firewall rules for telnet, that did not work, so I disabled the firewall, still cannot get a connection via port 25. I feel either port 25 is closed in another manor or the telnet is restricted to the localhost.
Also I cannot login to root to configure the Firewall Desktop GUI, only standard users, is this an issue? I also cannot login to the console as root even though I use the correct password.I can only su to root and sometimes it is a PITA. There must be some settings to clear these issues up...
I'd like to have an easy way to configure firewall, e.g. eable/disable what mythtv needs, or enable/disable what mediatomb needs. Basically open/close a few tcp and/or udp ports for all interfaces (I have two), or just one of them.
Is there a way to add my own trusted services for the firewall?
Other recommended ways to do that? Or just write a simple shell script?
I have installed squid using CentOS 5.When the server boot there are default services which are enabled at Boot time. My server is dedicated only for squid proxy server.I want to know how that when my server boot only the relevant services should start which may helpful for squid. Remaining unwanted services should be disable because they are just occupying memory of the server. Kindly guide me which command I should use and which services may I disable for smooth functioning of my squid

I added two new user to try on sending and receiving mail. It works. I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, I install VM player on it and run CentOS inside the VM Player.
I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?
I have installed squid using CentOS 5. The server is dedicated only for squid proxy server. I want to know how can I disable unwanted services which load at booting time. Like sendmail,samba,etc etc. These services take memory and are not in use. I does not know how can I make my server only for squid proxy service by removing unwanted services?
My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?
Anyway, according to the release notes, RHEL 6 has a PAE enabled kernel by default. Great... But that leaves me wondering why uname report SMP. Further, I'm provisioning some systems for QA use, and they're asking that PAE is disabled. My thinking is that since RHEL 6 requires PAE capability to install, there may be no way to disable it and the googling I've done seems to support this. tl;dr Why does a default kernel with PAE enabled report SMP on RHEL 6?
I have just installed ssh-server in my Ubuntu 10.04, and really want to know how to enable/disable it and I also want to be sure if the changes will take effect after the next boot or not, and how to do that?
how to disable gstreamer???? (and be able to re-enable it also?) i don't want to totally remove gstreamer - as it is required by alot of software. however, when i am using proaudio apps with low-latency having gstreamer enabled is a problem. this is because ( i think ) that my crappy intel-hda (STAC9200) only has one sub-device, while many other cards have multiple.
so when gstreamer is there, i will get more xruns, and a nasty message in dmesg, something along the lines of "intel-hda switching to polling mode". overall performance of the card will suck. BUT! if gstreamer is NOT there, i can run low-latency(2ms) with pretty much no xruns(jackd). the only time i get the odd one is if i am switching drum banks in a wine VST.
well, i remove pulseaudio when i install Fedora, gstreamer doesn't work properly after that, you can't use rhythmbox, or anything. but you will get much better latencies and generally the card is very useful. ie: i can manipulate many sounds/samples/synths in realtime, or actually record in ardour with a decent load...
I need to find out a command to enable and disable a secondary monitor using the Nvidia X Server. I've got a monitor attached to my laptop that I don't use all the time and would like to just have a launcher to switch between "twinview" and "disabled" quickly rather than having to go through the menus. It's physical position is vertically above the primary monitor so I have to put in a custom position every time I enable it.
In Fedora 11, we could use from: System -> Administrators -> Software Source for enable or disable repositories, by Check boxes. For example we disable rawhide or testing repositories! But in fedora 12 I don't see it in System -> Administrators -> Software Source! How I can enable or disable repositories, by Check boxes in Software Source?
I have been searching for the past hour trying to figure out how I can enable telnet on my Ubuntu 10.10 Virtual Machine.I am using VirtualBox to run my VM. I am trying to access that VM using PuTTy but most everything I have seen says I have to enable telnet first.The directions that I have found say to go to System > Administration > Services and enable telnet.I have nothing called Services under Administration.
I have a task I need to enable root telnet on SLES 11.I know about security hole, it is a must requirement accordingly to executing some scripts.Telnet works for the other user , but not for rootSSH work properly.Added pts/0 .. pts/24 to the /etc/securetty
None of these work. The only thing I've found that does work is:in.telnetd : IP_addressBut this is only a semi-viable solution because we will soon have multiple logins for the one username from different servers and sub-nets. Ideally, I'd like to be able to deny telnet and ssh access to this username regardless of where the login originates. I suppose it would be possible to specify each server IP, but that'll be a bear to maintain
