• Redirect all outgoing traffic on port 80 to a different IP on the same server

  - by Spacedust

  I have multiple IP addresses on the same server and I would like to redirect all outgoing traffic on port 80 to a different IP on the same server just no to use always main IP. Currently I'm using this: /sbin/iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source IP; and it works well, but it redirects everything and when I make backups over SSH backup it's failing. System: CentOS 5.8 64-bit

• IPTABLES route, redirect, forwardc traffic

  - by Anthony

  I am trying to redirect traffic from one IP reached on a specific port to a website. For example I have two external ips, lets say 194.145.63.1 and 194.145.63.2 set on one network card as 194.145.63.1 - eth0 and 194.145.63.2 -eth0:1 mywebsite.com allows access only from 194.145.63.1 and I want to set my rules like if I hit http://194.145.63.2:8080 to open mywebsite.com trough 194.145.63.1. Thanks in advance!

• proxy RDP traffic through SOCKS5 proxy, using Windows

  - by ptrn

  I'm having bit of trouble. I have a server at school that's hosting a database. Normally I've been connecting to it through a VPN-connection, but earlier today it went down. I've checked with other people, and it's definitely down, so the fault's probably not at my end. Is there a way I can proxy RDP traffic through a SOCKS5 proxy?

• route http and ssh traffic normally, everything else via vpn tunnel

  - by Normadize

  I've read quite a bit and am close, I feel, and I'm pulling my hair out ... please help! I have an OpenVPN cliend whose server sets local routes and also changes the default gw (I know I can prevent that with --route-nopull). I'd like to have all outgoing http and ssh traffic via the local gw, and everything else via the vpn. Local IP is 192.168.1.6/24, gw 192.168.1.1. OpenVPN local IP is 10.102.1.6/32, gw 192.168.1.5 OpenVPN server is at {OPENVPN_SERVER_IP} Here's the route table after openvpn connection: # ip route show table main 0.0.0.0/1 via 10.102.1.5 dev tun0 default via 192.168.1.1 dev eth0 proto static 10.102.1.1 via 10.102.1.5 dev tun0 10.102.1.5 dev tun0 proto kernel scope link src 10.102.1.6 {OPENVPN_SERVER_IP} via 192.168.1.1 dev eth0 128.0.0.0/1 via 10.102.1.5 dev tun0 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 1 This makes all packets go via to the VPN tunnel except those destined for 192.168.1.0/24. Doing wget -qO- http://echoip.org shows the vpn server's address, as expected, the packets have 10.102.1.6 as source address (the vpn local ip), and are routed via tun0 ... as reported by tcpdump -i tun0 (tcpdump -i eth0 sees none of this traffic). What I tried was: create a 2nd routing table holding the 192.168.1.6/24 routing info (copied from the main table above) add an iptables -t mangle -I PREROUTING rule to mark packets destined for port 80 add an ip rule to match on the mangled packet and point it to the 2nd routing table add an ip rule for to 192.168.1.6 and from 192.168.1.6 to point to the 2nd routing table (though this is superfluous) changed the ipv4 filter validation to none in net.ipv4.conf.tun0.rp_filter=0 and net.ipv4.conf.eth0.rp_filter=0 I also tried an iptables mangle output rule, iptables nat prerouting rule. It still fails and I'm not sure what I'm missing: iptables mangle prerouting: packet still goes via vpn iptables mangle output: packet times out Is it not the case that to achieve what I want, then when doing wget http://echoip.org I should change the packet's source address to 192.168.1.6 before routing it off? But if I do that, the response from the http server would be routed back to 192.168.1.6 and wget would not see it as it is still bound to tun0 (the vpn interface)? Can a kind soul please help? What commands would you execute after the openvpn connects to achieve what I want? Looking forward to hair regrowth ...

• Redirect all traffic to specified hosts behind NAT

  - by biesiad

  Is there a possibility to redirect all traffic to specified hosts behind NAT? For example i have a server, a domain "mydomain.com" and 3 hosts behind NAT. I wish to configure 3 subdomains: host1.mydomain.com host2.mydomain.com host2.mydomain.com and each of them to redirect all ports to specified host in local net. That redirection should provide funcionality like this: http://host1.mydomain.com (can be achieved using apache) ssh [email protected] (???) and other protocols on diferent ports Thanks for any help.

• Restrict traffic to local network and VPN using ufw or iptables

  - by Piezo Pea

  I want to restrict all traffic from my ubuntu-machine to come or go from the local network (eth0) or from or to my VPN (tun0). It should be possible to connect the router in the local network but not possible to leave the local network not using the VPN. Since i have no experience with iptables and i couldn't find some how-to i tried ufw but i did not succeed. Thank you for some hints or code snippets how to come closer!

• Secure linux distro that sends traffic through Tor

  - by gravestone

  I'm looking for a live Linux distro that is secure and preserves my anonymity online. For what I need, Tor seems to do the job – but such software requires configuration that someone who is not knowledgeable in how it works might find difficult. I was looking at 'Lightweight portable security' but it does not specify whether it sends all traffic through Tor. Does anyone know more information about it and/or any other such live Linux distro?

• isa 2006 blocks outgoing traffic with no rule specified

  - by codesnik

  I've created a rule near the top, allowing all outgoing traffic from "All Users" from specified IP range to external network. However, connections are blocked sometimes for no apparent reason. For example, one attempt to ssh to an external server would fail, and another immediatelly after that - won't. to the same server! logging shows thoose failed connections as denied, but "rule" column is blank. any suggestions?

• forward outbound traffic rule

  - by Claudiu

  I am trying to forward the outbound traffic to another server. Current rule is: /sbin/iptables -A OUTPUT -p tcp -s localhost -o 91.xxx.xxx.xxx --dport 65000:65010 -j ACCEPT but when I do a iptables -L, the rule its showed like this: ACCEPT tcp -- localhost.localdomain anywhere tcp dpts:65000:65010 So I guess my rule is bad written since the "destination" column shows "anywhere" Can you help me with this?

• Best Website Statistics tool for Drupal

  - by Olav

  What is the best free Website statistics setup I can have for Drupal 6 on Apache? Particularities: 1. Multisite install. Might want to look over several sites. Should be able to restrict view for clients to their own site. Some hits are bypassing Drupal. Some urls are not public. Some sites have little traffic, it would be nice to be able to exclude "own" traffic. Logged in users are not so important (It seems Google Analytics is popular)

• Inconsistent values in network switch throughput values

  - by Marcus Hughes

  Quite simple, I have a network switch with SNMP, and need to calculate the throughput of the switch port, so simply I use ifOutOctets. We transfer a file which is 145MB and if we use the total from the start, subtracted from the value at the end then the value is : 158901842 I simply can't get the value to match, or be anything similar to what the real transfer is. I understand that there may be excess traffic etc but I just can't get it to be anywhere similar (the server being tested has no traffic when this is not running) We have tried for a long time and suspect there may be an issue with the recording on the HP switch, do you have any suggestions, or how should we be calculating it? Thanks a lot in advance We have a HP ProCurve 1810G on 2.2

• Exchange 2010 DAG + VMWare HA = no support?

  - by Dan

  We currently have an Exchange 2003 clustered environment (two machine cluster) that we're looking to upgrade to 2010. We recently purchased a VMWare virtualization environment (three Dell R710's with an EMC NS-120 serving up NFS datastores - iSCSI is available) that we wish to use for this new environment. I'm seeing that Microsoft does not support Exchange 2010 DAGs with a virtualization high availability solution (see links below). I would like to utilize the DAG to ensure the data stays available if one host goes down, and HA to ensure that if the physical host goes down, the VM will come back up on the other available host. Does anybody know why MS does not support this? VMWare HA will only restart the VM if it is hung/down - I don't see any difference between this and restarting the physical box if someone pulled the power... Will we only run into issues with support if it has something to do with HA/DAG failover or will they see we have HA and tell us to put it on a physical box even if it has nothing to do with HA? If we disable HA for these VM's will that satisfy them on a support case? Has anybody set up an Exchange 2010 DAG on VMware with HA enabled? Will they have any issues with using an NFS datastore? We have much greater flexibility on the EMC with NFS vs iSCSI, so I would prefer to continue utilizing that. Thanks for any input! http://www.vmwareinfo.com/2010/01/verifying-microsoft-exchange-2010.html Take a look at the second image under "Not Supported" http://technet.microsoft.com/en-us/library/aa996719.aspx "Microsoft doesn't support combining Exchange high availability solutions (database availability groups (DAGs)) with hypervisor-based clustering, high availability, or migration solutions. DAGs are supported in hardware virtualization environments provided that the virtualization environment doesn't employ clustered root servers."

• Oracle Application Server Performance Monitoring and Tuning (CPU load high)

  - by Berkay

  Oracle Application Server Performance Monitoring and Tuning (CPU load high) i have just hired by a company and my boss give me a performance issue to solve as soon as possible. I don't have any experience with the Java EE before at the server side. Let me begin what i learned about the system and still couldn't find the solution: We have an Oracle Application Server (10.1.) and Oracle Database server (9.2.), the software guys wrote a kind of big J2EE project (X project) using specifically JSF 1.2 with Ajax which is only used in this project. They actively use PL/SQL in their code. So, we started the application server (Solaris machine), everything seems OK. users start using the app starting Monday from different locations (app 200 have user accounts,i just checked and see that the connection pool is set right, the session are active only 15 minutes). After sometime (2 days) CPU utilization gets high,%60, at night it is still same nothing changed (the online user amount is nearly 1 or 2 at this time), even it starts using the CPU allocated for other applications on the same server because they freed If we don't restart the server, the utilization becomes %90 following 2 days, application is so slow that end users starts calling. The main problem is software engineers say that code is clear, and the System and DBA managers say that we have the correct configuration,the other applications seems OK why this problem happens only for X application. I start copying the DB to a test platform and upgrade it to the latest version, also did in same with the application server (Weblogic) if there is a bug or not. i only tested by myself only one user and weblogic admin panel i can track the threads and dump them. i noticed that there are some threads showing as a hogging. when i checked the manuals and control the trace i see that it directs me the line number where PL/SQL code is called from a .java file. The software eng. says that yes we have really complex PL/SQL codes but what's the relation with Application server? this is the problem of DB server, i guess they're right... I know the question has many holes, i'd like to give more in detail but i appreciate the way you guide me. Thanks in advance ... Edit: The server both in CPU and Memory enough to run more complex applications

• Investigate high load on RHEL

  - by Adam Matan

  One of my RHEL 5 was showing high load (~4-5) on uptime. The load increased, and when it reached 6 (±), the server froze and needed restart. top-wise, the server had no significant CPU or memory issues and sar showed no increase in iowait. Therefore, the thrashing must have been related to other factors. Any ideas how to investigate this? In particular, how do I know that which processes are waiting in the queue?

• How to prevent Google Website Optimizer from making Google Analytics spike Direct Traffic and lower Bounce Rate?

  - by Scott

  I am using Google Website Optimizer (GWO) and Google Analytics. Whenever a person (Google Website Optimizer) does a javascript redirect, Google Analytics will change the referrer. When the referrer changes, the traffic source becomes yourself and is changed to Direct Traffic. For Example: A visitor goes to google: searches for my great service. Clicks the link that goes to website page: /home/ At this point, Google Analytics tracks the referrer as Google. However, /home/ has a GWO javacript redirect to a battery of A/B tests. /home-1/ or /home-2/ or /home-3/ When the redirect from /home/ occurs to /home-1/, google analytics on the /home-1/ page now thinks the referrer is yourself and converts the referrer to Direct Traffic since the Direct Traffic bucket is the unknown. I'm really surprised that GWO and GA do this when they both come from google. Now, How does one fix this to prevent the overwrite of the referrer using GWO?

• Diagnosing a Memcache server with a high cache miss rate

  - by Hobozilla

  Hi Guys, What tools are available to debug a memcache server with a high miss rate (62%)? Ideally I would like to know the keys for the top cache misses, but I would just settle for seeing the keys of live get requests and working it out from there. I have tried a few web based things (phpMemcache) but it doesn't have the information I need. I also tried statsproxy-1.0 which appeared to do what I need but would not play ball. Many thanks

• Diagnostic high load sys cpu - low io

  - by incous

  A Linux server running Ubuntu 12.04 LTS with LAMP has a strange behaviour since last week: - cpu %sys higher than before, nearly equal %usr (before that, %sys just little compare with %usr) - IO reduce by half or 1/3 compare with the week before I try to diagnostic the process/cpu by some command (top/vmstat/mpstat/sar), and see that maybe it's a bit high on interrupt timer/resched. I don't know what that means, now open to any suggestion.
