Hi Guys, OK, I figured out the problem, It would seem that Comcast spelling my DNS entry wrong would do it! I have done this a zillion times, I was totally stumped as to what I would be missing this time. Thanks everyone for their help. -Jason ----- Original Message ----- From: "Kai Schaetzl" <maillists at conactive.com> To: centos at centos.org Sent: Tuesday, December 22,

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running

In following up on the rsh "problem" I was having earlier, I decided to try out the suggestion Felipe sent about using system-config-securitylevel-tui to open up ports 513 and 514, but that doesn't seem to do the job, either. # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere

Hi, I've been able to get tinc setup when I flush all my iptables, but after enabling iptables and a delay I get a "Destination Net Unknown". I have three host (HOME10.0.3.2, MASTER 10.0.3.1, WEB 10.0.3.3) MASTER and WEB are in Digital ocean in the same data centre. HOME <---> MASTER <---> WEB I've tried multiple forwarding/masquerading/etc rules and

Hi All, Is anyone versed in Zimbra? I have most things working except some MTA issue. I tried posting on the Zimbra forums after reading the docs, but my post was labeled as SPAM and the moderators have not replied to my private message to get my post reviewed. Who uses this type of method for getting help anyway? Aren't the days of Bulletin Board BBS's gone? Anyway... I installed ZCS

Can you post your Tinc configuration too?

Your output looks like iptables -L -n. Can you add the -v option to check if the rule did handle packages? On 01/26/2017 05:39 PM, Thierry wrote: > ACCEPT tcp -- anywhere anywhere tcp dpt:4711

Dear List! I use a shorewall 2.0.8 on a Debian sarge system. I use a DSL connection to the Internet (ppp0 - eth1 to the modem) and a bridge to the local lan. The bridged config i''ve made with bridge.html from the shorewall site. The Bridge is between local net and a openvpn tap device. This works. I ccan make tunnels, and a can make a lot of things through the firewall. I can get a list

I've been getting LOTS of messages like the below in the daily log, and from all indications, it appears to all be related to the cpu; the machine is just over a year old, and was the old vortex.wa4phy;net server from the downtown co-lo site. Aside from huge log files, and lots of other fluff, numerous problems of other nature have started cropping up. Anyone have any suggestions as to

Any help here? I have included all of the output of the suggested diags that Thomas said I should run, but I admit that I'm not sure what I'm looking for, as I'm not familiar with RPC functionality on Linux. Something is not working with RPC on my Samba 4.0.3 server. (FWIW, it doesn't work with IPTables stopped either.) > On Mon, Feb 25, 2013 at 2:21 PM, Mike Stroven wrote:

Hi all, I''m tring to isolate P2P traffic, specifically BitTorrent, for my QoS scripts. I can''t seem to completely isolate ALL BitTorrent traffic.

I''m having a problem with the Shorewall firewall and CUPS printing interfering with each other. My Linux firewall machine is acting as both a CUPS server and client for all of my tests. Shorewall 2.0.13 CUPS 1.1.22-2 Linux kernel 2.6.9 CUPS was working fine to print to my Epson C84 (network connected via a Netgear PS101 print server using lpd://PS101.IP.address/raw ) until I

I know i'm new to the list but i'd like to propose something for tincd daemon. I'd like to mark all sockets established by a tincd process with a mark passed as an argument in the command line. What could be the purpose of this new option? The goal of this option is to be able to have several tincd process running at the same time using the same port but using different ip. In

After getting a reasonably configured NFS4 setup working on my Scientific Linux server, I spent a majority of my evening trying to do the same with my Centos 5 box, with fruitless results.

Hi all, I have done some extensive searching, and drawn a blank so far... Nothing odd is reported in samba logs, or in the syslog file. However, if I try to play an avi straight off the samba server, on an XP client with MP10, it brings the whole deal to its knees after a few mins at the most. I have to hard reset the server. Other than this, all my other uses are flawless (game server,

Sorry if this has been covered before. I setup a new Samba server using RedHat EL 3, and samba 3.0.2-6.3E (the version that comes with Redhat). We were seeing an intermittant 20 seconcd delay when grabbing a directory listing, but only from XP, win 2k was fine. I couldn't completely nail down when the delay occured but it seemed to be when the directory or share hadn't been accessed
