  • Can't access apache from outsite my local network

    - by valter
    UPDATED: Now, when I type my external ip like xxx.xxx.xxx.xxx:8079, i can access xampp defaults page. But the strange is that when someone else from outside my network, try to access it using the same ip, it doesnt work. I Think it should, because its the external ip. I'm getting crazy. I have tried for hours to access xampp defaults page from outside my local network. My ISP blocks port 80 and 8080. So I changed apache to listen to port 8079 Listen 8079 My local computer ip is 10.1.1.2 I can access the webserver, from any computer on my local network when I type http://10.1.1.2:8079 I also oppended the port 8079 on my modem, as the image shows bellow. (I think i did it right) When apache is running on my computer, if I test the port 8079 at http://canyouseeme.org/ i get the message "Success: I can see your service on xxx.xxx.xxx.xxx on port (8079) Your ISP is not blocking port 8079" If apache is not running I get "Error: I could not see your service on xxx.xxx.xxx.xxx on port (8079) Reason: Connection refused". So, it's clear that the port 8079 is oppened. But when I type xxx.xxx.xxx.xxx:8079 on google chrome for example, I get Oops! Google Chrome could not connect to xxx.xxx.xxx.xxx:8079 What can I do to solve this, to allow apache to server the pages? I don't know what else I shoud configure. Please, help me. Thanks.

  • oracle access on vmware fusion

    - by gaudi_br
    Hello, I'm running snow leopard and I'm doing some development that requires some network knowledge. I've installed vmware fusion 3.0 and I've set up a virtual machine with windows 2003 server. I need to mimic the exact configuration of another server in the network, so I really need to run the versions I'll be mentioning here. Besides, I set up two network configurations on the VM: one NAT config (so that I can have internet access) and one host-only config (because I need to use another server's mac adress and my local area network might have a problem with it) From the installation of windows 2003, I then installed oracle 10.2.0.1. During the installation I received a warning about the primary ip-address of the system being dhcp assigned, but I ignored it (maybe it was a mistake)... Now, from experience, unless the DHCP assigned address changes, I should be able to access the guest system's database from the host system, so I went to safari and tried to access the oracle em. As it turns out, because my computer is on a company network, the company's DNS doesn't know about the virtual machine, unless of course I switch to a bridged network config. However, I don't want to do that because I don't to mix up the domains. So I guess the question is, how can I define my own dns or router, or whatever it is that I need to define so that whenever I try the guest system's ip address form the host, it will use the vmnet1 or vmnet8 interface define by vmware and bypass the dns configuration of my local area network. I'd also like to know what to do incase I want to change ip addresses on the guest machine without having oracle go haywire (I've noticed a few folders on the structure which are specific for the very first IP Address)... Any help would be appreciated. Thanks in advance.

  • Trouble linking libboost libraries to compile sslsniff on RHEL

    - by rwong48
    Trying to build sslsniff on a RHEL 5.2 system here. When compiling sslsniff on RHEL I hit the same errors when using libboost packages (from repositories like rpmforge) and compiling libboost from source (which appeared to be successful.) I tried this on a fresh system as well (no previous/failed/garbage installs of libboost etc.) # make g++ -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\"

  • Please Critique this PHP Login Script

    - by NightMICU
    Greetings, A site I developed was recently compromised, most likely by a brute force or Rainbow Table attack. The original log-in script did not have a SALT, passwords were stored in MD5.

  • Problems configuring nameserver in plesk

    - by Saif Bechan
    Hello, i have some troubles with setting up a nameserver in PLESK for months now. I have tried all possible scenario's but i can not get this to work. I am really in need for some help, and if you can i will really appreciate it. Basically what i want is to just set up a nameserver in PLESK. I have a primary IP, and my host gave me a secondary nameserver i can use. My host is leaseweb in the netherlands. I have made some screenshots of the important parts in my opinion, maybe you guys can see some errors in them. To use the secondary nameserver provided by leaseweb i had to enable ACL on that account, i did so and made a screenshot of that too. The DNS recursion is set to localnets. These settings have not changed for months, so the dns should be fully updated everywhere. The check i run is the following: https://www.sidn.nl/over-nl/aanvraag...-server-check/ Domeinnaam (inclusief .nl): rdshosting.nl Eerste Nameserver: ns1.rdshosting.nl Eerste IP: 62.212.66.33 Tweede Nameserver: ns7.leaseweb.net Tweede ip: 62.212.76.50 If i run the dns check of the netherlands it gives me the following errors: primary name server "ns1.rdshosting.nl." Error: specified name server is not listed as NS record. All public name servers for a domain must also be listed as NS records in the zone of the domain. This domain was specified explicitly as a name server, but not found in the zone description of the primary name server. TE.6a rdshosting.nl. 86400 IN SOA ns1.rdspartners.nl. saif2k.hotmail.com.

  • Stop duplicate icmp echo replies when bridging to a dummy interface?

    - by mbrownnyc
    I recently configured a bridge br0 with members as eth0 (real if) and dummy0 (dummy.ko if). When I ping this machine, I receive duplicate replies as: # ping SERVERA PING SERVERA.domain.local (192.168.100.115) 56(84) bytes of data. 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=1 ttl=62 time=113 ms 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=1 ttl=62 time=114 ms (DUP!) 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=2 ttl=62 time=113 ms 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=2 ttl=62 time=113 ms (DUP!) Using tcpdump on SERVERA, I was able to see icmp echo replies being sent from eth0 and br0 itself as follows (oddly two echo request packets arrive "from" my Windows box myhost): 23:19:05.324192 IP myhost.domain.local > SERVERA.domain.local: ICMP echo request, id 512, seq 43781, length 40 23:19:05.324212 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324217 IP myhost.domain.local > SERVERA.domain.local: ICMP echo request, id 512, seq 43781, length 40 23:19:05.324221 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324264 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324272 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 It's worth noting, testing reveals that hosts on the same physical switch do not see DUP icmp echo responses (a host on the same VLAN on another switch does see a dup icmp echo response). I've read that this could be due to the ARP table of a switch, but I can't find any info directly related to bridges, just bonds. I have a feeling my problem lay in the stack on linux, not the switch, but am opened to any suggestions. The system is running centos6/el6 kernel 2.6.32-71.29.1.el6.i686. How do I stop ICMP echo replies from being sent in duplicate when dealing with a bridge interface/bridged interfaces? Thanks, Matt [edit] Quick note: It was recommended in #linux to: [08:53] == mbrownnyc [gateway/web/freenode/] has joined ##linux [08:57] <lkeijser> mbrownnyc: what happens if you set arp_ignore to 1 for the dummy interface? [08:59] <lkeijser> also set arp_announce to 2 for that interface [09:24] <mbrownnyc> lkeijser: I set arp_annouce to 2, arp_ignore to 2 in /etc/sysctl.conf and rebooted the machine... verifying that the bits are set after boot... the problem is still present I did this and came up empty. Same dup problem. I will be moving away from including the dummy interface in the bridge as: [09:31] == mbrownnyc [gateway/web/freenode/] has joined #Netfilter [09:31] <mbrownnyc> Hello all... I'm wondering, is it correct that even with an interface in PROMISC that the kernel will drop /some/ packets before they reach applications? [09:31] <whaffle> What would you make think so? [09:32] <mbrownnyc> I ask because I am receiving ICMP echo replies after configuring a bridge with a dummy interface in order for ipt_netflow to see all packets, only as reported in it's documentation: http://ipt-netflow.git.sourceforge.net/git/gitweb.cgi?p=ipt-netflow/ipt-netflow;a=blob;f=README.promisc [09:32] <mbrownnyc> but I do not know if PROMISC will do the same job [09:33] <mbrownnyc> I was referred here from #linux. any assistance is appreciated [09:33] <whaffle> The following conditions need to be met: PROMISC is enabled (bridges and applications like tcpdump will do this automatically, otherwise they won't function). [09:34] <whaffle> If an interface is part of a bridge, then all packets that enter the bridge should already be visible in the raw table. [09:35] <mbrownnyc> thanks whaffle PROMISC must be set manually for ipt_netflow to function, but [09:36] <whaffle> promisc does not need to be set manually, because the bridge will do it for you. [09:36] <whaffle> When you do not have a bridge, you can easily create one, thereby rendering any kernel patches moot. [09:36] <mbrownnyc> whaffle: I speak without the bridge [09:36] <whaffle> It is perfectly valid to have a "half-bridge" with only a single interface in it. [09:36] <mbrownnyc> whaffle: I am unfamiliar with the raw table, does this mean that PROMISC allows the raw table to be populated with packets the same as if the interface was part of a bridge? [09:37] <whaffle> Promisc mode will cause packets with {a dst MAC address that does not equal the interface's MAC address} to be delivered from the NIC into the kernel nevertheless. [09:37] <mbrownnyc> whaffle: I suppose I mean to clearly ask: what benefit would creating a bridge have over setting an interface PROMISC? [09:38] <mbrownnyc> whaffle: from your last answer I feel that the answer to my question is "none," is this correct? [09:39] <whaffle> Furthermore, the linux kernel itself has a check for {packets with a non-local MAC address}, so that packets that will not enter a bridge will be discarded as well, even in the face of PROMISC. [09:46] <mbrownnyc> whaffle: so, this last bit of information is quite clearly why I would need and want a bridge in my situation [09:46] <mbrownnyc> okay, the ICMP echo reply duplicate issue is likely out of the realm of this channel, but I sincerely appreciate the info on the kernels inner-workings [09:52] <whaffle> mbrownnyc: either the kernel patch, or a bridge with an interface. Since the latter is quicker, yes [09:54] <mbrownnyc> thanks whaffle [edit2] After removing the bridge, and removing the dummy kernel module, I only had a single interface chilling out, lonely. I still received duplicate icmp echo replies... in fact I received a random amount: http://pastebin.com/2LNs0GM8 The same thing doesn't happen on a few other hosts on the same switch, so it has to do with the linux box itself. I'll likely end up rebuilding it next week. Then... you know... this same thing will occur again. [edit3] Guess what? I rebuilt the box, and I'm still receiving duplicate ICMP echo replies. Must be the network infrastructure, although the ARP tables do not contain multiple entries. [edit4] How ridiculous. The machine was a network probe, so I was (ingress and egress) mirroring an uplink port to a node that was the NIC. So, the flow (must have) gone like this: ICMP echo request comes in through the mirrored uplink port. (the real) ICMP echo request is received by the NIC (the mirrored) ICMP echo request is received by the NIC ICMP echo reply is sent for both. I'm ashamed of myself, but now I know. It was suggested on #networking to either isolate the mirrored traffic to an interface that does not have IP enabled, or tag the mirrored packets with dot1q.

    iftop is great tool to view almost live bandwidth usage distinguished by source-ip source-port destination-ip destination port. I'm using it to see which client's ip is using most bandwidth. Now I would like to store output somewhere. iftop uses ncurses so iftop > log.txt does not work as expected, result file is not readable. Is there any tool like this which can be used to pipe output to a text file? Thanks for your replies.

    - by Anirudh Goel
    I am using a Belkin G Wireless Router F5D7234, and i have a DSL connection with only a ethernet cable. So i connected the cable to the Modem port and allowed it to use Dyanmic IP, it worked successfully and an ip was assigned to it and multiple computers could connect to it and browse. But after some time the power went off and after then upon rebooting it is taking about half hour to get an IP address. Upon seeing the log i see this entry repeatedly 07/02/2010 23:22:34 DHCP Client: [WAN]Could not find DHCP daemon to get information 07/02/2010 23:22:32 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:30 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:28 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:26 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:26 DHCP Client: [WAN]Could not find DHCP daemon to get information 07/02/2010 23:22:24 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:22 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:20 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:18 DHCP Client: [WAN]Send Discover Any idea what i can do? I tried using another belkin router of same model and make and there also i faced the same problem.

  • Tunnel into Sonicwall VPN while on Sonicwall wifi?

    - by Patrick Harrington
    Hey all, I am able to hit my company's VPN while I am at home using a dedicated IP with no issue. When I am at work, the VPN we use (a Sonicwall router/VPN/wifi access point), I can get outside internet fine, but am unable to connect to the VPN. I know that the wifi puts me on a different subnet, and when I try to connect to the normal VPN IP it won't work, and a traceroute just times out. Any suggestions? Might there be an internal IP I need to hit while here at work?

  • MMC and Server Manager Authentication Errors - Access Denied

    - by Vazgen
    I'm trying to connect remotely from my Windows 8 client to manage my Hyper-V Server 2012. I have done everything I can find to configure remote management of the server including: Added a net user on server Enabled anonymous dcom access on server and client Added firewall rules for "Windows Firewall Remote Management" and "Windows Management Instrumentation (WMI)" on server Added firewall exception on server for client IP Added cmdkey on client Added server to TrustedHost list on client Added LocalAccountTokenFilter policy registry entry on server Added client IP to server's host file Added server IP to client's host file I cannot believe I am still getting these errors. What's even more strange is that I can connect in Hyper-V Manager and create VM's but not in MMC and Server Manager. I also get Access Denied trying to Open the Authorization Store on my server from my client using Authorization Manager. I'm providing all the errors because I have a feeling they root from the same problem. Does anybody see anything I missed?

  • Blocking yandex.ru bot

    - by Ross
    I want to block all request from yandex.ru search bot. It is very traffic intensive (2GB/day). I first blocked one C class IP range, but it seems this bot appear from different IP ranges. For example: spider31.yandex.ru - 77.88.26.27 spider79.yandex.ru - 95.108.155.251 etc.. I can put some deny in robots.txt but not sure if it respect this. I am thinking of blocking a list of IP ranges. Can somebody suggest some general solution.

  • What does it mean when ARP shows <incomplete> on eth1

    - by Geoff Dalgas
    We have been using HAProxy along with heartbeat from the Linux-HA project. We are using two linux instances to provide a failover. Each server has with their own public IP and a single IP which is shared between the two using a virtual interface (eth1:1) at IP: 69.59.196.211 The virtual interface (eth1:1) IP 69.59.196.211 is configured as the gateway for the windows servers behind them and we use ip_forwarding to route traffic. We are experiencing an occasional network outage on one of our windows servers behind our linux gateways. HAProxy will detect the server is offline which we can verify by remoting to the failed server and attempting to ping the gateway: Pinging 69.59.196.211 with 32 bytes of data: Reply from 69.59.196.220: Destination host unreachable. Running arp -a on this failed server shows that there is no entry for the gateway address (69.59.196.211): Interface: 69.59.196.220 --- 0xa Internet Address Physical Address Type 69.59.196.161 00-26-88-63-c7-80 dynamic 69.59.196.210 00-15-5d-0a-3e-0e dynamic 69.59.196.212 00-21-5e-4d-45-c9 dynamic 69.59.196.213 00-15-5d-00-b2-0d dynamic 69.59.196.215 00-21-5e-4d-61-1a dynamic 69.59.196.217 00-21-5e-4d-2c-e8 dynamic 69.59.196.219 00-21-5e-4d-38-e5 dynamic 69.59.196.221 00-15-5d-00-b2-0d dynamic 69.59.196.222 00-15-5d-0a-3e-09 dynamic 69.59.196.223 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 225.0.0.1 01-00-5e-00-00-01 static On our linux gateway instances arp -a shows: peak-colo-196-220.peak.org (69.59.196.220) at <incomplete> on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-222.peak.org (69.59.196.222) at 00:15:5d:0a:3e:09 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 Why would arp occasionally set the entry for this failed server as <incomplete>? Should we be defining our arp entries statically? I've always left arp alone since it works 99% of the time, but in this one instance it appears to be failing.

Swapping network cards and switches I noticed the link light on the port of the switch for the failed windows server was running at 100Mb instead of 1Gb on the failed interface. I moved the cable to several other open ports and the link indicated 100Mb for each port that I tried. I also swapped the cable with the same result. I tried changing the properties of the network card in windows and the server locked up and required a hard reset after clicking apply. This windows server has two physical network interfaces so I have swapped the cables and network settings on the two interfaces to see if the problem follows the interface. If the public interface goes down again we will know that it is not an issue with the network card. (We also tried another switch we have on hand, no change) Changing network hardware driver versions We've had the same problem with the latest Broadcom driver, as well as the built-in driver that ships in Windows Server 2008 R2. Replacing network cables As a last ditch effort we remembered another change that occurred was the replacement of all of the patch cords between our servers / switch. We had purchased two sets, one green of lengths 1ft - 3ft for the private interfaces and another set of red cables for the public interfaces. We swapped out all of the public interface patch cables with a different brand and ran our servers without issue for a full week ... aaaaaand then the problem recurred. Disable checksum offload, remove TProxy We also tried disabling TCP/IP checksum offload in the driver, no change. We're now pulling out TProxy and moving to a more traditional x-forwarded-for network arrangement without any fancy IP address rewriting. We'll see if that helps.

  • Emails forwarded via postfix get flagged as spam and forged in Gmail

    - by Kendall Hopkins
    I'm trying to setup a forwarding only email server. I'm running into the problem where all messages forwarded via postfix are getting put into gmail's spam folder and getting flagged as forged.

    Hello. I'm trying to set up video surveillance system using ip cameras and zonealarm on Arch Linux. I set up fixed ip address, I've managed to get streams from cameras, etc. However, after restart of the machine, I can not start apache again. I checked configuration of rc.conf, and saw that static ip configuration has been deleted, and also secondary nameserver in resolv.conf. Tried to re-write these with correct parameters, but now with no effect.

  • Bridging with aliased Ethernet card for Virtualizing with single Ethernet card

    - by user113505
    We are having a server with good CPU and RAM,so we are planning to do XEN virtualization on ubuntu 12.04 server to handle high traffic. The plan is to keep the host machine only to manage VMs(no NAT ing). A New public IP will be assigned to that VM,For that i think we need a Bridge to external network(Since my Machine has only single ethernet card aliased with 4 different Pub IP's) Is it possible to create a bridge using aliased IP single ethernet card aliased to 4 pub IPs Do we need an additional Ethernet card to do Bridging.Only have ssh access to the machine. Any suggestions will be appreciated.

  • Can't access network share with name defined in hosts file

    - by Einar Egilsson
    I have a network share on a machine that I can only reach by IP address. I then defined an alias for the IP in my hosts file so I could use that instead of the IP but then I can't log on to the share, I just get the logon prompt again and again. So basically this: \\172.17.0.48\SomeShare works but this \\myalias\SomeShare doesn't. myalias is defined in c:\windows\system32\drivers\etc\hosts as 172.17.0.48 myalias And I can use the alias for remote desktop without problems. Can anyone tell me why this doesn't work for fileshares?

  • Redirect as a backup trick? w/o modifying DNS?

    - by acidzombie24
    I specifically looked up how to do something like this ( Can you set a backup ip for your server in DNS? ) and the answer basically was you can't. If i say specify 2 ip addresses could i somehow use a HTTP response header to ignore it temporary (say 5mins) and go to the other IP address? Or maybe i can play dead however i'm unsure how to play dead using nginx. I then would like to be available after my box notice the other box is down and be some kind of readonly server. I'm sure something like this has been implemented i am just wondering how i might implement it with 2 boxes. I'm sure it isn't very difficult? How might i redirect traffic from a backup box to my main server without modifying the DNS?

  • Variable parsing with Bash and wget

    - by Bill Westrup
    I'm attempting to use wget in a simple bash script to grab a jpeg image from an Axis camera. This script outputs a file named JPEGOUT, instead of the desired output, which should be a timestamp jpeg (ex: 201209292040.jpg) . Changing the variable in the wget statement from JPEGOUT to $JPEGOUT makes wget fail with "wget: missing URL" error. The weird thing is wget parses the $IP vairable correctly. No luck on the output file name. I've tried single quotes, double quotes, parenthesis: all to no luck. Here's the script !/bin/bash IP=$1 JPEGOUT= date +%Y%m%d%H%M.jpg wget -O JPEGOUT http://$IP/axis-cgi/jpg/image.cgi?resolution=640x480&compression=25 Any ideas on how to get the output file name to parse correctly?

  • IPFW not locking people out

    - by Cole
    I've had some brute-forcing of my ssh connection recently, so I got fail2ban to hopefully prevent that. I set it up, and started testing it out by giving wrong passwords on my computer. (I have physical access to the server if I need to unblock myself) However, it never stops me from entering passwords. I see in /var/log/fail2ban.log that fail2ban kicked in and banned me, and there's a ipfw entry for my IP, but I'm not locked out. I've changed the configuration around, and then tried just using the ipfw command myself, but nothing seems to lock me out. I've tried the following blocks: 65300 deny tcp from 10.0.1.30 to any in 65400 deny ip from 10.0.1.30 to any 65500 deny tcp from 10.0.1.30 to any My firewall setup has a "allow ip from any to any" rule after these though, maybe that's the problem? I'm using Mac OS 10.6 (stock ipfw, it doesn't seem to have a --version flag) Thanks in advance.

  • Cisco Catalyst 65XX and traffic shaping

    - by Nadz Goldman
    Hello! I have Cisco Catalyst 65XX, many VLANs and about ~1300 users. Users connected to some D-Link switches with second-level management. D-Link switches come to my Cisco Catalyst 65XX by VLANs. So, how I can shape traffic per user? If I use something like this: access-list 145 permit ip any host 192.168.0.1 access-list 145 permit ip any host 192.168.0.2 access-list 145 permit ip any host 192.168.0.3 ... int Gi0/1 traffic-shape group 145 128000 7936 7936 1000 will I have shape traffic per user or it will shape traffic only on interface? I mean - every user will have 128kb/s (per user) or everybody will have 128kb/s ? If it will be for everybody, then what is the solution of my question: how every user can have 128kb/s ?
