Server :: Accessing Internal Webserver From Public Webserver

Dec 18, 2009

Ok let's say I have Apache Webservers on 2 different machines within my network, I have http://outterABC.com setup at dyndns.org to point to my modem at home, and my router forwards Port 80 to the ServerA Machine (i.e. 192.168.0.3). I can access my webpage I setup for the Server A Machine.

But what I want to try and do is somehow access my ServerB machine's website that is on my same network. I tried something like this http://ServerB.outterABC.com and the apache page came up with something like the page wasn't available. I want to access the content of the ServerB website, but because I have only one router, i can only forward Port 80 site traffic to my ServerA machine's website. I'm sure it's a different syntax I should use but i'm just not sure what I should enter to bring up the apache root web page for the Server B website via http://outterABC.com

I tried setting up DNS A records on ServerA, but I don't think it will work with what i'm trying to do above.

Nov 22, 2010

we have a DNS server is being used for external clients .Recently we installed awstat monioring tool in ordr to collect either ftp or mail statistic.

The second nameserver line doesn't work. DNS server's conf file looks like :

search mycompany.com
nameserver 127.0.0.1
nameserver LAN_IP_Address

General :: Centos With Apache Webserver - Change The Localhost.local?

Dec 27, 2010

I have setup a Linux Centos with apache server on it in a home network. Everything works fine. When I access the webserver I put in the address bar the IP address of the server which is 192.168.0.150 and when hit enter, it prompts the page where I have to put login information. The login information is set to: username: admin@localhost.local password: *************

It takes long time for authentication go through and load the page eventhough I am accessing the site in a same home local area network with fast ethernet connection. How can I change the localhost.local to something else like maybe [URL] instead and if I have to change settings in other files as well?

CentOS 5 :: Syslog-ng Remote Clients But No Local Logs?

May 13, 2010

I installed syslog-ng so I can receive remote logs. this is working however since I disabled syslog on my syslog-ng server I am not logging in /var/log/messages cron and some others.locally)I know this is because my syslog-ng.conf only references remote and not local.How can I edit the syslog-ng.conf file so that I can receive remote and local? I tried this however when adding in portions of the default config, I only receive local and not remote logs anymore. I am forwarding my config.

# syslog-ng configuration file.

# This should behave pretty much like the original syslog on RedHat. But

Ubuntu Networking :: Windows Clients Lose Ability To Resolve Local Domain Names

Dec 2, 2010

I have an internal domain (dev.lan) for which my Ubuntu server is authoritative. We have a number of subdomains under that domain (test.dev.lan, svn.dev.lan, etc.). The server also acts as the primary DNS server for my office. It was originally set up under Ubuntu 8 and worked great.

However, ever since we upgraded to Ubuntu 10, our Windows clients periodically lose the ability to resolve domains on the dev.lan domain. Internal IP addresses can still be pinged from the Windows machines so it does not appear to be a network-connectivity issue. External domain names continue to resolve without any problems. The only workaround is to restart networking on the Windows clients. It's frustrating because it happens several times a day.

bind9 logs no obvious error messages.

Ubuntu Security :: Ufw Not Blocking Ports?

Apr 1, 2010

After reading a lot about networking and security I decided to check the security of my own ubuntu box. So I went installing Nmap and discovered that port 139 was "open". Since I 'd read how to use ufw I created a deny rule for port 139. After a second scan with Nmap it still said that port 139 was open as shown below.

Ubuntu Security :: UFW Is Blocking Connections Even Though It's Set To Allow For In/Out

Aug 1, 2011

I might be misunderstanding the log but it looks like UFW is blocking connections. I want to allow all incoming and outgoing. I guess what I'm saying is that the servers on my computer will open ports but all other ports should respond with closed just like a default Ubuntu install. Trying to use UFW to monitor connections without really doing any firewalling.

Code:
Aug 1 07:14:07 universal-mechanism kernel: [311111.963762] [UFW BLOCK] IN=eth0 OUT= MAC=00:1f:c6:8a:e9:66:00:01:5c:32:f4:c1:08:00 SRC=72.21.203.146 DST=174.44.178.56 LEN=40 TOS=0x00 PREC=0x00 TTL=233 ID=51984 DF PROTO=TCP SPT=80 DPT=54466 WINDOW=8201 RES=0x00 RST URGP=0

Security :: Logging/Blocking LAN Traffic?

Apr 26, 2010

Where I work we have a lan, it is almost 100% windows machines except for 2 CentOS machines in which some clients connect to, via VPN. (very small network, <50 ip's used)

I would like to know if there is a way to block access from that machines to others in the network. I'm already logging traffic (with IPTraff) to see if they're accessing other machines in the network others than the ones they should connect.

Security :: Red Hat SeLinux Is Blocking Ssh And Http?

Feb 3, 2011

When I turn on my SeLinux to enforcing mode on my Red Hat system ssh stops working and my http server stops responding.

I went into the SeLinux GUI and enabled things in there but still it wont work.

Any thoughts on what to check?

permissive mode and disabled they work

I read several articles that say it should not be affect by SeLinux and the setting look correct but the only thing I do is turn on SeLinux and ssh /httpd stop working

ps -eZ | grep sshd
system_u:system_r:unconfined_t:SystemLow-SystemHigh 432 ? 00:00:00 sshd
system_u:system_r:unconfined_t:SystemLow-SystemHigh 2426 ? 00:00:00 sshd

Security :: OpenVPN Security For Clients?

Jan 8, 2010

I have a running proxy server that I wish to also turn into a VPN server.The VPN is not used so much that a user can access the network but is used so that they can obtain a geo specific IP address for their applications (the proxy server only does this for HTTP).I would therefore like to block off the VPN from accessing any of my Linux box's ports such as email, web server etc.Clients are given local IPs of 172.16.0.x.What should I take into consideration to block off clients from accessing dangerous stuff on the network?

Fedora Security :: Blocking Ip Address Range?

Dec 31, 2010

I'm assuming that the following should block the complete 178.123.xxx.xxx address range.

Code:
iptables -I INPUT -s 178.123.0.0/24 -j DROP
Then I believe that I need to save this change.

Code:
service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]

However, I'm not so sure that it is actually working based on the fact that there continues to be access to my wiki from that address range. The following is after I made the firewall change.

Quote:

178.123.177.61 - - [31/Dec/2010:04:24:40 -0500] "GET /mywiki/Opera%20Web%20Browser?action=edit&editor=text HTTP/1.1" 200 6346 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"
code....

Let me state that I'm new at this iptables thing. I did some reading and decided that I need to make the above change to the firewall but it doesn't seem to make a difference.
