  • Apache with multiple domains, single IP, VirtualHost is catching the wrong traffic

    - by apuschak
    I have a SOAP web service I am providing on a apache web server. There are 6 different clients (IPs) that request data and 3 of them are hitting the wrong domain. I am trying to find a way to log which domain name the requests are coming from. Details: ServerA is the primary ServerB is the backup domain1.com - the domain the web service is on domain2.com - a seperate domain that server seperate content on ServerB ServerA is standalone for now with its own IP and DNS from domain1.com. This works for everyone. ServerB is a backup for the web service, but it already hosts domain2.com. I added entries into the apache configuration file like: <VirtualHost *:443> ServerName domain2.com DocumentRoot /var/www/html/ CustomLog logs/access_log_domain2443 common ErrorLog logs/ssl_error_log_domain2443 LogLevel debug SSLEngine on ... etc SSL directives ... </VirtualHost> I have these for both 80 and 443 for domain1 and domain2 with domain1 being second. The problem is when we switch DNS for domain1 from ServerA to ServerB, 3 out of the 6 clients show up in the debug logs as hitting domain2.com instead of domain1.com and fail their web service request because domain2.com is first in the apache configuration file and catching all requests that don't match other virtualhosts, namely domain1.com. I don't know if they are hitting www.domain1.com, domain1.com (although I added entries for both) or using the external IP address or something else. Is there a way to see which URL they are hitting not just the page request or someother way to see why the first domain is catching traffic meant for the second listed domain? In the meantime, I've put domain1.com higher in the apache configuration than domain2.com. Now it catches the requests for all clients and works, however I don't know what it is catching and would like to make domain2.com the first entry again with a correct entry for domain1.com, for however they are hitting it. Thank you for your help! Andrew

  • Connecting to network device behind NAT from local LAN using the external port and IP

    - by lumbric
    I noticed at several different LANs connected to the Internet through a NAT the following phenomena. There is a server in the LAN and there is a port forwarding to reach this server also from outside the LAN through the NAT. E.g. consider a LAN with the address 192.168.0.* and a SSH server at 192.168.0.2 with port 22 and a forwarding from port 2222 at the NAT 192.168.0.1 to 192.168.0.2:22. If the NAT's external IP is 44.33.22.11, one can connect to the SSH server through 44.33.22.11:2222. Surprisingly this works only from outside the LAN. If one tries to connect to 44.33.22.11:2222 from behind the NAT, there is no answer. Of course one could simply use 192.168.0.2:22, but often it is simpler to use the external IP. The typical use case for me is the configuration on a laptop computer. Usually the user uses any arbitrary Internet connection to connect to his home or office server, but sometimes he will use also the LAN to connect to it and it would be annoying to have to different configurations or bookmarks. Why does it fail to connect from inside the LAN? Is there any good work around?

  • Strange Domain name under the same IP Address

    - by Mike Chip
    There's something really weird happening in my server. But first things first: I wanted to have my website and chose the domain name "myowndomain.com", Now on my domain registrar I point "myowndomain.com" to the address of my recently setup VPS, let's say 50.50.50.50 So I installed everything I needed to run my website, and I started to notice strange queries coming from different IP Addresses. Like these [client 123.123.123.123] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php [client 456.456.456.456] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php or like this (Really a long line, I cut some things) GET /?s=vod-show-id-22-area-%E5%85%B6%E4%BB%96-language-%E9%9F%A9%E8%AF%AD.html HTTP/1.1" 301 295 "http://v.strangedomain.com/?s=vod-s ...[cut]... spider" That above is happening the most. The 'strangedomain.com' returns the same IP address of my VPS which my website is hosted on. The whois of such domain shows it's registered to a chinese. But the street name didn't look so right (like a huge single word), so I think all of that info might be fake, but still might be a chinese. I also noticed that all 'clients' trying to access the 'strangedomain.com' is coming from china. If I type in the browser 'strangedomain.com', I see my website. I'm worried, because my website is actually an e-commerce. I don't know if 'strangedomain.com' WAS a website on 50.50.50.50 in the not so far past, or if it's something else.

  • Cisco ASA 5505 network route for static IP hosts

    - by TheCapn
    I've configured my internal VLAN using the most basic settings where ports 1-7 are assigned from a pool of addresses in the range 192.168.15.5 - 192.168.15.36. These hosts are given access to the internet and it works great. What I'm trying to set up now is allowing users who are connected to the device and specify their IP (say I connect and request 192.168.15.45) are given internet access and can still work alongside DHCP hosts. Those with a DHCP assigned address are blocked from the internet. Mostly the issue resides in that I am very new to working with the device. I feel that the solution is easy but I'm not looking in the right spots and don't have the correct terminology down to google it. Do I need to define access control lists? Group policies? a new VLAN? The rules that are set up seem to be specific to the entire /24 subnet but when I request a static IP outside of the DHCP range I get blocked from other hosts and the internet.

  • 2 Web Servers, 2 Domains, 1 WAN IP configuration

    - by Tillman32
    The Problem: I have 2 domains, 2 web servers, 1 WAN IP. This is on a home network, so I don't have any crazy router or anything with the right tools, at least I don't think I do. I have a Dlink DIR-655 router. I need to be able to forward the website to the right box. 1 server is hosting www.site1.com, and the other should be hosting, www.site2.com. I forwarded the domain, to a port that is forwarded to that box. wanip:1235, 1235 is then forwarded to the internal IP of site2's server. But when I go to www.site2.com I get the 404 page of www.site1.com. I need www.site2.com to go to the right server. Is this something I can do in the virtual hosts of www.site1.com or is it something else. Also, if this isn't entirely possible, or if its a big process, I can just move www.site1.com to the www.site2.com's server, and use virtual hosts, that is an option that I would be okay with.

  • Parsing ip addresses in php

    - by user2938780
    I am trying to get the number of active connections (Real Time) from a log file by IP connected and having a Play status but instead, it's giving me the total number of IP with status play. The number doesn't decrease at all. Keeps on increasing as soon as a new ip is added. How can I fix it? Here my code: $stringToParse = file_get_contents('wowzamediaserver_access.log'); preg_match_all('/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/', $stringToParse, $matchOP); echo "Number of connections: ".sizeof(array_unique($matchOP[0])); HERE IS THE LOG: 2013-10-30 14:54:36 CET stop stream INFO 200 account1 - _defaultVHost_ account1 _definst_ 149.21 streamURL 1935 fullStreamURL IP_ADDRESS_1 http (cupertino) - 2013-10-30 14:56:12 CET play stream INFO 200 account2 - _defaultVHost_ account1 _definst_ 149.21 streamURL 1935 fullStreamURL IP_ADDRESS_2 rtmp (cupertino) - 2013-10-30 14:58:23 CET stop stream INFO 200 account2 - _defaultVHost_ account1 _definst_ 149.21 streamURL 1935 fullStreamURL IP_ADDRESS_2 rtmp (cupertino) - 2013-10-30 14:58:39 CET play stream INFO 200 account1 - _defaultVHost_ account1 _definst_ 149.21 streamURL 1935 fullStreamURL IP_ADDRESS_1 http (cupertino) - 2013-10-30 14:59:12 CET play stream INFO 200 account2 - _defaultVHost_ account1 _definst_ 149.21 streamURL 1935 fullStreamURL IP_ADDRESS_2 rtmp (cupertino) - I want to be able to count the IP whenever it has a "PLAY" status and don't count it whenever it's "STOP" 2013-10-30 14:59:00 CET play stream INFO 200 tv2vielive - _defaultVHost_ tv2vielive _definst_ 0.315 [any] 1935 rtmp://tv2vie.zion3cloud.com:1935/tv2vielive 78.247.255.186 rtmp http://www.tv2vie.org/swf/flowplayer-3.2.16.swf WIN 11,7,700,202 92565864 3576 3455 1 0 0 0 tv2vielive - - - - - rtmp://tv2vie.zion3cloud.com:1935/tv2vielive/tv2vielive rtmp://tv2vie.zion3cloud.com:1935/tv2vielive/tv2vielive - rtmp://tv2vie.zion3cloud.com:1935/tv2vielive - 2013-10-30 14:59:04 CET stop stream INFO 200 tv2vielive - _defaultVHost_ tv2vielive _definst_ 4.75 [any] 1935 rtmp://tv2vie.zion3cloud.com:1935/tv2vielive 78.247.255.186 rtmp http://www.tv2vie.org/swf/flowplayer-3.2.16.swf WIN 11,7,700,202 92565864 3576 512571 1 7222 0 503766 tv2vielive - - - - - rtmp://tv2vie.zion3cloud.com:1935/tv2vielive/tv2vielive rtmp://tv2vie.zion3cloud.com:1935/tv2vielive/tv2vielive - rtmp://tv2vie.zion3cloud.com:1935/tv2vielive - Any solutions?

If that IP changes to STOP then it wont count.

  • Bind9 as a caching resolver fails with mismatch ID on localhost but not external IP

    - by argibbs
    I'm running Ubuntu 12.04 LTS on a machine on my private network. I have bind9 installed (v9.8.1-P1) via aptitude, so it appears to have put all the bits in the right places and the service starts automatically. I plan on adding some zones later, but first I'm just trying to get it working as a caching resolver. I installed bind, configured it, and starting using it. Initially I thought it was working ok, but then I found some sites weren't being resolved. I've pinned it down to being linked to the size of the result and bind failing-over to TCP mode. So: I'm trying to find out why bind is failing when I query for domain info and the result is 512 bytes (causing a truncation and retry on TCP). Specifically it fails with ID mismatches if I point dig at localhost, but works when I query the machine's own IP (192.168.0.2). This appears to be backwards to the problem that most people have when using bind (fails on external ip, works on localhost). If I do dig @localhost google.com (which has a response of <512 bytes) then it works; I get no warnings, and plenty of output. $ dig @localhost google.com ; <<>> DiG 9.8.1-P1 <<>> @localhost google.com [snip lots of output] ;; Query time: 39 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) ;; WHEN: Thu Oct 17 23:08:34 2013 ;; MSG SIZE rcvd: 495 If I do dig @localhost play.google.com (which has a larger response) then I get back something like: $ dig @localhost play.google.com ;; Truncated, retrying in TCP mode. ;; ERROR: ID mismatch: expected ID 3696, got 27130 This seems to be standard, documented behaviour - when the UDP response is large (here 'large' == 512 bytes) it falls back to TCP. The ID mismatch is not expected though. If I do dig @192.168.0.2 play.google.com then I still get the warning about using TCP mode, but it otherwise works $ dig @192.168.0.2 play.google.com ;; Truncated, retrying in TCP mode. ; <<>> DiG 9.8.1-P1 <<>> @192.168.0.2 play.google.com [snip most of the output] ;; Query time: 5 msec ;; SERVER: 192.168.0.2#53(192.168.0.2) ;; WHEN: Thu Oct 17 23:05:55 2013 ;; MSG SIZE rcvd: 521 At the moment I've not set up any zones in my local instance, so it's just acting as a caching resolver. My options config is pretty much unchanged from standard, I've got the following set: options { directory "/var/cache/bind"; allow-query { 192.168/16; 127.0.0.1; }; forwarders { 8.8.8.8; 8.8.4.4; }; dnssec-validation auto; edns-udp-size 4096 ; allow-transfer { any; }; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; And my /etc/resolv.conf is just nameserver 127.0.0.1 search .local The problem definitely seems linked to the failover to TCP mode: if I do dig +bufsize=4096 @localhost play.google.com then it works; no warning about failover to TCP, no ID mismatch, and a standard looking result. To be honest, if there was a way to force bind to use a much larger UDP buffer, that'd probably be good enough for me, but all I've been able to find mention of is max-udp-size 4096 and that doesn't change the behaviour in any way. I've also tried setting edns-udp-size 512 in case the problem is some weird EDNS issue with my router (which seems unlikely since the +bufsize=4096 flag works fine). I've also tried dig +trace @localhost play.google.com; this works. No truncation/TCP warning, and a full result. I've also tried changing the servers used in the forwarder (e.g. to OpenDNS), but that makes no difference. There's one last data point: if I repetitively do dig @localhost play.google.com I don't always get an ID mismatch, but sometimes a REFUSED error. I'm much more likely to get a REFUSED error if I dig the non-localhost IP (192.168.0.2) first: $ dig @localhost play.google.com ;; Truncated, retrying in TCP mode. ; <<>> DiG 9.8.1-P1 <<>> @localhost play.google.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 35104 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;play.google.com.

  • Bridging LXC containers to host eth0 so they can have a public IP

    - by Vianney Stroebel
    UPDATE: I found the solution there: http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#No_traffic_gets_trough_.28except_ARP_and_STP.29 # cd /proc/sys/net/bridge # ls bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-call-ip6tables bridge-nf-filter-vlan-tagged # for f in bridge-nf-*; do echo 0 $f; done But I'd like to have expert opinions on this: is it safe to disable all bridge-nf-*? What are they here for? END OF UPDATE I need to bridge LXC containers to the physical interface (eth0) of my host, reading numerous tutorials, documents and blog posts on the subject. I need the containers to have their own public IP (which I've previously done KVM/libvirt). After two days of searching and trying, I still can't make it work with LXC containers. The host runs a freshly installed Ubuntu Server Quantal (12.10) with only libvirt (which I'm not using here) and lxc installed. I created the containers with : lxc-create -t ubuntu -n mycontainer So they also run Ubuntu 12.10. Content of /var/lib/lxc/mycontainer/config is: lxc.utsname = mycontainer lxc.mount = /var/lib/lxc/test/fstab lxc.rootfs = /var/lib/lxc/test/rootfs lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 lxc.network.name = eth0 lxc.network.veth.pair = vethmycontainer lxc.network.ipv4 = 179.43.46.233 lxc.network.hwaddr= 02:00:00:86:5b:11 lxc.devttydir = lxc lxc.tty = 4 lxc.pts = 1024 lxc.arch = amd64 lxc.cap.drop = sys_module mac_admin mac_override lxc.pivotdir = lxc_putold # uncomment the next line to run the container unconfined: #lxc.aa_profile = unconfined lxc.cgroup.devices.deny = a # Allow any mknod (but not using the node) lxc.cgroup.devices.allow = c *:* m lxc.cgroup.devices.allow = b *:* m # /dev/null and zero lxc.cgroup.devices.allow = c 1:3 rwm lxc.cgroup.devices.allow = c 1:5 rwm # consoles lxc.cgroup.devices.allow = c 5:1 rwm lxc.cgroup.devices.allow = c 5:0 rwm #lxc.cgroup.devices.allow = c 4:0 rwm #lxc.cgroup.devices.allow = c 4:1 rwm # /dev/{,u}random lxc.cgroup.devices.allow = c 1:9 rwm lxc.cgroup.devices.allow = c 1:8 rwm lxc.cgroup.devices.allow = c 136:* rwm lxc.cgroup.devices.allow = c 5:2 rwm # rtc lxc.cgroup.devices.allow = c 254:0 rwm #fuse lxc.cgroup.devices.allow = c 10:229 rwm #tun lxc.cgroup.devices.allow = c 10:200 rwm #full lxc.cgroup.devices.allow = c 1:7 rwm #hpet lxc.cgroup.devices.allow = c 10:228 rwm #kvm lxc.cgroup.devices.allow = c 10:232 rwm Then I changed my host /etc/network/interfaces to: auto lo iface lo inet loopback auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 92.281.86.226 netmask 255.255.255.0 network 92.281.86.0 broadcast 92.281.86.255 gateway 92.281.86.254 dns-nameservers 213.186.33.99 dns-search ovh.net When I try command line configuration ("brctl addif", "ifconfig eth0", etc.) my remote host becomes inaccessible and I have to hard reboot it.

  • Opening a port to make a connection in Windows 7 [closed]

    - by jannes braet
    Possible Duplicate: trouble with opening a port to make a connection I have watched a video on how to open my ports in Windows 7. I followed the example by going to my "firewall" in "advanced settings" and I made new rules in "inbound rules" and in "outbound rules". I chose to allow connections to all ports, but if I try it with canyouseeme, then it says I can't find the configured port. Maybe it is because the site is wrong, but I don't really believe so. Could someone tell me how I open my ports so that I can connect to them and others to connect to them via the internet (if they have my ip-adress of course)?

  • Duplicate a collection of entities and persist in Hibernate/JPA

    - by Michael Bavin
    Hi, I want to duplicate a collection of entities in my database. I retreive the collection with: CategoryHistory chNew = new CategoryHistory(); CategoryHistory chLast = (CategoryHistory)em.createQuery("SELECT ch from CategoryHistory ch WHERE ch.date = MAX(date)").getSingleResult; List<Category> categories = chLast.getCategories(); chNew.addCategories(categories)// Should be a copy of the categories: OneToMany Now i want to duplicate a list of 'categories' and persist it with EntityManager. I'm using JPA/Hibernate. UPDATE After knowing how to detach my entities, i need to know what to detach: current code: CategoryHistory chLast = (CategoryHistory)em.createQuery("SELECT ch from CategoryHistory ch WHERE ch.date=(SELECT MAX(date) from CategoryHistory)").getSingleResult(); Set<Category> categories =chLast.getCategories(); //detach org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); session.evict(chLast);//detaches also its child-entities? //set the realations chNew.setCategories(categories); for (Category category : categories) { category.setCategoryHistory(chNew); } //set now create date chNew.setDate(Calendar.getInstance().getTime()); //persist em.persist(chNew); This throws a failed to lazily initialize a collection of role: entities.CategoryHistory.categories, no session or session was closed exception. I think he wants to lazy load the categories again, as i have them detached. What should i do now?

  • Exporting from SSRS 2008 ReportViewer to Excel Causes Duplicate Columns

    - by Daniel Coffman
    I have a report that groups months by quarters, so each quarter has three months and the display of the months under the quarter is toggled by the quarter header. It looks just fine in the ReportViewer, but when exporting to Excel the first month in the quarter with data is duplicated and appended to the end of the quarter group. Here is what it looks like in the ReportViewer (with Quarters 2 and 4 expanded, note May and June do not have any data and show blank columns by design): http://i.imgur.com/MykZE.png This is how it looks when exported to Excel: http://i.imgur.com/zfLuk.png The collapsed Quarter should only show the LAST month in the quarter. You can see that in the Excel export July is inserted in Q1 even though it should be hidden entirely since that quarter is collapsed, December is appended to Q2, January is inserted into Q3, and April is duplicated and appended to Q4. Exporting the any format OTHER than Excel works correctly and does not insert these columns. A similar bug for rows was filed and marked as "by design": http://connect.microsoft.com/SQLServer/feedback/details/508823/reporting-services-2008-group-by-export-to-excel-duplicate-rows-csv-ok-pdf-ok How do I stop the export to Excel feature from inserting these duplicate columns?

  • Xcode - duplicate Target - new Target fails to build

    - by SirRatty
    Hi all, using Xcode 3.2.5 on 10.6.6 (10J521) I have an Xcode project containing 1 Target: "MyApp". It builds and runs successfully. As well as source and resource files, the Target contains a "Copy Files" build phase which copies "Sparkle.framework" in. The framework is in the same directory as the project. I want to duplicate this Target. Steps taken: Did "Clean all Targets". Right-clicked on the "MyApp" Target within Xcode, and then chose "Duplicate". Renamed the duplicated target to "MyAppTarget2". Selected "MyAppTarget2" as the Active Target from the popup menu in the top-left. Did "Build". The problem: error: Sparkle/Sparkle.h: No such file or directory This is puzzling! Each Build step appears to have been replicated in the duplicated Target, including the "Copy Files" phase. The Sparkle.framework exists at the path indicated by [Get Info on the Copy Phase item]. If I right-click on the Sparkle.framework file within the "Copy Files" build phase of the duplicated Target, and select "Reveal in Finder", then the correct Sparkle.framework file is shown. The required file exists at Sparkle.framework/Headers/Sparkle.h If I switch back to the original "MyApp" target, it builds and runs successfully. Am I doing something obviously wrong here? Thanks.

  • Limit TCP requests per IP

    - by asmo
    Hello! I'm wondering how to limit the TCP requests per client (per specific IP) in Java. For example, I would like to allow a maximum of X requests per Y seconds for each client IP. I thought of using static Timer/TimerTask in combination with a HashSet of temporary restricted IPs. private static final Set<InetAddress> restrictedIPs = Collections.synchronizedSet(new HashSet<InetAddress>()); private static final Timer restrictTimer = new Timer(); So when a user connects to the server, I add his IP to the restricted list, and start a task to unrestrict him in X seconds. restrictedIPs.add(socket.getInetAddress()); restrictTimer.schedule(new TimerTask() { public void run() { restrictedIPs.remove(socket.getInetAddress()); } }, MIN_REQUEST_INTERVAL); My problem is that at the time the task will run, the socket object may be closed, and the remote IP address won't be accessible anymore... Any ideas welcomed! Also, if someone knows a Java-framework-built-in way to achieve this, I'd really like to hear it.

  • Upgraded to Xcode 4 -- Endless stream of duplicate symbol errors causing build errors

    - by D-Nice
    Everything was working perfectly fine in Xcode 3 yesterday before I upgraded. So I completed the upgrade, restarted my computer, and opened my old project. I had to reconfigure a few settings like the header paths so that I could begin to compile. I'm using AdWhirl for ad mediation, and at this point my errors begin to read something like duplicate symbol _OBJC_METACLASS_$_SBJSON in /Users/Admin/Desktop/TMapLiteAdwhirl/AdWhirl/MMSDK/libMMSDK.a(SBJSON.o) and /Users/Admin/Library/Developer/Xcode/DerivedData/TruxMapLite-bgpylibztethnlhkfkdumpvrjvgy/Build/Intermediates/TruxMapLite.build/Debug-iphoneos/TruxMapLite.build/Objects-normal/armv6/SBJSON.o for architecture armv6 The library it's referring to is the SDK for one of the ad networks I'm including in AdWhirl. Both of the 'duplicate symbols' refer to the SAME FILE, but they use different paths. If I had still had XCode 3, I would simply try excluding these libraries from the build path, but I have no idea how that can be done in Xcode 4. I've tried everything all the way down to deleting the library and all associated files from my project, but when I do this, i will simply get the same type of error for a different library in the AdWhirl directory. This is incredibly frustrating because before my upgrade everything was working smoothly and I was prepared to submit my binary. If anyone has any advice, id be more than happy to give it a try. Thanks!

  • Use MySQL trigger to update another table when duplicate key found

    - by Jason
    Been scratching my head on this one, hoping one of you kind people and direct me towards solving this problem. I have a mysql table of customers, it contains a lot of data, but for the purpose of this question, we only need to worry about 4 columns 'ID', 'Firstname', 'Lastname', 'Postcode' Problem is, the table contains a lot of duplicated customers. A new table is being created where each customer is unique and for us, we decide a unique customer is based on 'Firstname', 'Lastname' and 'Postcode' However, (this is the important bit) we need to ensure each new "unique" customer record also can be matched to the original multiple entries of that customer in the original table. I believe the best way to do this is to have a third table, that has 'NewUniqueID', 'OldCustomerID'. So we can search this table for 'NewUniqueID' = '123' and it would return multiple 'OldCustomerID' values where appropriate. I am hoping to make this work using a trigger and the on duplicate key syntax. So what would happen is as follows: An query is run taking the old customer table and inserting it in to the new unique table. (A standard Insert Select query) On duplicate key continue adding records, but add one entry in to the third table noting the 'NewUniqueID' that duped along with the 'OldCustomerID' of the record we were trying to insert. Hope this makes sense, my apologies if it isn't clear. I welcome and appreciate any thoughts on this one! Many thanks Jason

  • Rewriting Live TCP/IP (Layer 4) Streams

    - by user213060
    I want to rewrite TCP/IP streams. Ettercap's etterfilter command lets you perform simple live replacements of TCP/IP data based on fixed strings or regexes. Example: if (ip.proto == TCP && tcp.dst == 80) { if (search(DATA.data, "gzip")) { replace("gzip", " "); msg("whited out gzip\n"); } } if (ip.proto == TCP && tcp.dst == 80) { if (search(DATA.data, "deflate")) { replace("deflate", " "); msg("whited out deflate\n"); } } http://ettercap.sourceforge.net/forum/viewtopic.php?t=2833 I would like to rewrite streams based on my own filter program instead of just simple string replacements. Anyone have an idea of how to do this? Is there anything other than Ettercap that can do live replacement like this, maybe as a plugin to a VPN software or something? The rewriting should occur at the transport layer (Layer 4) as it does in this example, instead of a lower layer packet-based approach. Thanks!

  • Removing duplicate images (deduplication) - calculating "overlap" of images

    - by jotango
    Hello, I have a ton of product images on our file system. Our code removes 100% identical images (or does not allow them to be uploaded). However our sellers often upload items pictures which are very similar, but not exactly. They could have more whitespace, a worse quality (compression), a different size etc. Is there any way I can calculate the degree of overlap between two images, to flag ones for deletion? Kind of like a Levenshtein distance between two images... Any pointers would be very cool. Thanks!

  • Configuring RAID1 on HP Proliant Microserver N54L / Ubuntu 14.04.1 LTS [duplicate]

    - by Chris Beach
    This question already has an answer here: Cant find my harddrives in ubuntu installation? 2 answers I've bought a N54L and fitted two 3GB drives. Keen to get set up with RAID1. BIOS: SATA controller mode set to "RAID" RAID Option ROM utility: both physical drives set up as one logical drive When I came to install Ubuntu (14.04.1), both drives appeared during the setup process. I was only expecting to see the logical drive, although I'm a complete novice with RAID. I've read that the HP Proliant Microservers don't have "proper" RAID support, and require some kind of driver to be installed. I've tried a few HP utilities from the following apt repo: deb http://downloads.linux.hp.com/SDR/repo/mcp wheezy/current non-free On installation, most say "server not supported" Would appreciate your advice.

  • How to connect devices behind Comcast router/modem with devices behind wireless router

    - by deeperDATA
    I know this is going to seem like a simple solution but I have been unable to find a clear answer through Google. Simple office setup: I have a Comcast modem/router that has 4 hard wired ports. In one of those ports I have a Cisco wireless router which also has 4 of its own ports. What is the method for getting devices behind the modem/router to ping/communicate with devices behind the wireless router? They are all on the same subnet but the IP ranges differ. The router produces 192.168.1.1 by default while the Comcast modem/router produces 10.1.10.1 by default. I think what I'm attempting to do might be considered "extending" the modem/router's network but I'm not sure. Thank you in advance for your assistance.

  • Linux accessibility: Slow Keys causing duplicate key strokes

    - by skypanther
    I'm exploring the accessibility features within Gnome and having trouble with Slow Keys. My input is always doubled. Press a key briefly and I get nothing as you'd expect. Press just a bit longer and which ever key I'm pressing is input twice. Hello becomes HHeelllloo. I'm running Debian Lenny 5.0.6, kernel 2.6.26-2-686, GNOME Desktop 2.22.3 running within a VirtualBox session. I did some googling and didn't find others having similar troubles. Maybe it's a vbox thing? Any ideas how to fix this so I don't get the duplicates? It makes it impossible to log back in when the screen lock kicks on!
