  • Why is port 444 open on this router?

    - by TJ Thind
    I have a Cisco RV110W. I ran nmap at it from the outside and nmap reports that the router has tcp port 444 open. Yet there are no port forwarding rules specifying this port. It should as far as I can tell, be closed. There's even a service listening to that port which I can connect to through telnet. I threw some SNPP commands at it but the service doesn't respond to any of them so I don't believe it's SNPP. Does anyone have any idea why this particular router has tcp port 444 open? I haven't been able to find anything in the manual or on Cisco's website.

  • Add multiple @groups to valid users

    - by skids89
    In smb.conf I have the line valid users = @Staff @Directors Is this a valid syntax to add two groups to the valid users line? It does not seem to work right on our xp pro clients. If not which of the following is the proper way (if any) to make two groups valid users of this network drive? Which is proper for windows clients? valid users = +Staff +Directors Or do I need to use the & valid users = &Staff &Directors Or some combo of the two? valid users = &+Staff &+Directors valid users = +&Staff +&Directors

  • Video for HTML5 -- ffmpeg commands

    - by StackOverflowNewbie
    I'd like to allow my users to upload their videos (no clue what format they'll be) and convert them into the following formats: MP4 Ogg Webm I think it's those 3 formats I need in order to support HTML5, at least per http://mediaelementjs.com/. I've tried various commands that I found on the web. Some of them worked, some of them used old syntax, some of them worked only on my computer and not others, some of them gave conflicting information, etc. Are there any FFMPEG experts here that can provide the "proper" commands? I'm not particularly trying to achieve anything special. I just want to be able to convert the video into something playable on the web. Highest quality, smallest filesize, etc. are the basic goals. Something that works without a lot of special configurations would be ideal, too. I ran into a lot of "missing presets" problems.

  • Linux box acting as wireless access point to share the internet connection

    - by Suresh
    A linux machine is connected to internet over two interfaces ppp0 and ppp1 using two modems. Also this machine acts as wireless access point through an interface say, eth0 with ip address 192.168.1.1 and acts as gateway for the connected devices through this network with subnet mask 255.255.255.0 Now is it possible to achieve the following: When any of the connected devices through wireless AP needs internet connection linux machine has to use ppp1 interface for internet. If any of the applications on the linux machine needs internet connection linux machine should use ppp0 interface for the internet. Can this be achieved by adding rules to chains in filter/nat tables? If the kernel routing table has a default rule to route the default traffic through interface ppp0, wil kernel completely ignore ppp1 for internet? PS: new to networking and routing concepts, If the question is not clear leave a comment, will try to give more information.

    I'm using mongoexport to export some collections into CSV files, however when I try to target fields which are members of an array I cannot get it to export correctly. command I'm using: mongoexport -d db -c collection -fieldFile fields.txt --csv > out.csv and the contents of fields.txt is similar to id name address[0].line1 address[0].line2 address[0].city address[0].country address[0].postcode where the BSON data would be: { "id": 1, "name": "example", "address": [ { "line1": "flat 123", "line2": "123 Fake St.", "city": "London", "country": "England", "postcode": "N1 1AA" } ] } what is the correct syntax for exporting the contents of an array?

  • Routing only some local IPs through VPN on dd-wrt

    - by bo-inge-ostberg
    Much similar to this entry: http://serverfault.com/questions/94283/using-dd-wrt-to-connect-to-vpn-and-forward-all-traffic-of-certain-devices-through , I have set up my router with dd-wrt + OpenVPN to connect to a VPN. This works fine, and all traffic from behind the router goes through the VPN. How do I route(?) traffic in the router so that only certain IPs from the LAN will go through the VPN, while the others take the "normal" route? Is it also possible to allow traffic from certain local IPs to go ONLY through the VPN, making it impossible for them to use the regular internet connection if the VPN is down? I know this question was answered in the post I linked to, but that just doesn't seem to work for me. The routing table and rules change, but traffic still just goes through the VPN.

  • Xcopy /exclude does not exclude some of the specified criteria

    - by Richard Z.
    Good afternoon. I want xcopy to copy all files meeting a certain criteria located in the C drive to a specific folder, except ones located in the directories specified in excl.txt. The exclusions only work partially - the files located in %systemroot%, %programfiles% and in each profile's appdata are still copied, even though those directories are listed in excl.txt. How do I make xcopy skip those directories, preferentially still using environment vars to specify the paths? My current syntax is: xcopy /s /c /d /h /i /r /y /g /f /EXCLUDE:excl.txt %systemdrive%\*.doc f:\test\ excl.txt currently contains the following: \%temp%\ \%userprofile%\appdata \%programfiles%\ \%programfiles(x86)%\ \%systemroot%\ \%programdata%\ appdata windows %programfiles% Thank you very much.

  • Managing Active Directory Group Membership with a Non-Administrator Account In Server 2008

    - by Laranostz
    I am running Server 2008 R2 in an Active Directory Domain Environment. I have created a group in Active Directory and I have delegated management authority to that group to a user. I want this user to be able to add and remove accounts as needed from that group so that they are exercising some measurement of control without giving them other authority. When I have the user attempt to access the Active Directory Users & Computers Console it prompts them for Administrator credentials. They are using Remote Desktop to access the server, because they do not have Windows 7, and firewall rules prevent using the Remote Management Kit. I do not want to provide them with any level of Administrative rights except the minimum required for them to add/remove users from this group. There are two servers that 'talk' to each other in this isolated environment, a domain controller and a member server, both are only reachable through RDP. Any suggestions?

  • Cant logon to domain over site-to-site vpn

    - by 3molo
    Tied together branch office with main office over two Cisco ASAs. The (internal) networks on either side can communicate with the other. I can ping, use the DC's DNS service and even join a domain on a new client. I can't however logon, I get the "domain controller is not available" error message on client. I find nothing peculiar in DC's event logs. Sicne it's site-to-site (with ping), it's always up so it should work. No firewall rules (except allow any any) between the two networks (of either side). Main site internal net: 10.10.10.0/24 Branch office net: 10.180.3.0/24 Am I overlooking something here? Where should I start investigating this?d

  • With Monit, how do I restart a process when a directory timestamp check fails?

    - by Alterscape
    In my /etc/monit/monitrc I have the following lines: check process foo_server with pidfile /var/run/bwam_server.pid start program = "/Users/foo/foo_server.sh start" stop program = "/Users/foo/foo_server.sh stop" check directory foo_data path "/Users/foo/Library/Application Support/foo_server/data" if timestamp > 1 minute then alert #if timestamp > 1 minute then restart foo_server I know I shouldn't have some of this stuff in my home directory, but this aside: if I uncomment the last line, Monit tells me syntax error on foo_server -- but I am, as far as I understand, correctly defining the process -- how else do I reference it?

  • Gre tunnel Linux Cisco

    - by mezgani
    I've created a GRE tunnel between LAN A and LAN B. LAN A is behind a router, and LAN B is behind a Linux box and this box has a pppoe interface. When i do tcpdump on Linux box i see that the traffic is routerd to Linux box (tunnel end), so my need is routing the tunnel traffic to internet. I've added these rules to my iptables script, and i stay unable to connect to internet from LAN A Permitting Linux to act as router (necessary to forward packets) echo "1" /proc/sys/net/ipv4/ip_forward iptables -A INPUT -p 47 -j ACCEPT iptables -A FORWARD -i ppp0 -j ACCEPT iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o gre0 -j MASEQUARADE What i've forgot to set in this case?

  • Attempting to migrate to Aptana from Dreamweaver - how to?

    - by Kerry
    I have been using Dreamweaver for years, and have used Dreamweaver MX, Dreamweaver MX 2004, Dreamweaver 8 & Dreamweaver CS4. They all carry a common theme and were relatively easy to migrate to each other. I use, however, very few features of dreamweaver. Specifically: Syntax highlighting Telesense FTP management/site management The search/replace The idea I get from Aptana is its much more geared toward the web development/programmer side of things, have better visualizations of classes, etc., and handle everything else just as well. The problem is it is not at all clear to me. I managed to start a new project, but it didn't associate it with an FTP. So, I created an FTP, and it looks like I can have many FTPs for one project. My question then is, is there a tutorial or guide to migrating to Aptana from a Dreamweavor's perspective?

  • hiera_include equivalent for resource types

    - by quickshiftin
    I'm using the yumrepo built-in type. I can get a basic integration to hiera working yumrepo { hiera('yumrepo::name') : metadata_expire => hiera('yumrepo::metadata_expire'), descr => hiera('yumrepo::descr'), gpgcheck => hiera('yumrepo::gpgcheck'), http_caching => hiera('yumrepo::http_caching'), baseurl => hiera('yumrepo::baseurl'), enabled => hiera('yumrepo::enabled'), } If I try to remove that definition and instead go for hiera_include('classes'), here's what I've got in the corresponding yaml backend classes: - "yumrepo" yumrepo::metadata_expire: 0 yumrepo::descr: "custom repository" yumrepo::gpgcheck: 0 yumrepo::http_caching: none yumrepo::baseurl: "http://myserver/custom-repo/$basearch" yumrepo::enabled: 1 I get this error on an agent Error 400 on SERVER: Could not find class yumrepo I guess you can't get away from some sort of minimal node declaration w/ hiera and resource types? Maybe hiera_hash is the way to go? I gave this a shot, but it produces a syntax error yumrepo { 'hnav-development': hiera_hash('yumrepo') }

  • What advantages does mod_evasive have over mod_security2 in terms of DDOS protection?

    - by Martynas Sušinskas
    Good day, I'm running an Apache2 server in front of a Tomcat and I need to implement a DDOS protection mechanism on the Apache2 layer. I have two candidates: mod_evasive and mod_security2 with the OWASP core rule set. Mod_security is already installed for overall protection, but the question is: is it worth adding mod_evasive besides mod_security just for the DDOS (does it have any major advantages) or the OWASP crs rules in the /experimental_rules/ directory (modsecurity_crs_11_dos_protection.conf) provide the same protection? Or it's just a matter of preference? The sites are not very high traffic normally. Thank you for your answers, Martynas

  • How to test if SYN and FIN are both dropped at the same time in hping3?

    - by snow
    One of the rules to prevent unexpected attack is to prevent SYN & FIN being used together. SYN and FIN are both set $IPT -A INPUT -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP How do I use hping to test if this iptable rule works? hping3 192.168.7.0 --keep -S -F??? Is this complete? When just type iptables -L, it shows: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere DROP tcp -- anywhere anywhere tcp flags:FIN,SYN/FIN,SYN WHY do I need to put the "SYN,FIN" twice before drop? Is it because one for source and one for destination?

  • How much traffic a linux-based shaper would be able to chew

    - by facha
    Hi, everyone I have a linux based traffic shaper (iptables + tc htb policy). It works in bridge mode. Shapes traffic based on IPs and ports (there are about 100 rules in the "mangle" chain of iptables). Right now its throughoutput is about 100 mb/s (I don't remember pps, there are about 800 users in the network). Just was wondering - when I will hit the limit. How much traffic could a linux-based shaper possibly get throuhg it. If you have one under heavy load, please could you write what machine you use and what load there is. Or if you have any other info about the subj, please write as well. Thanks in advance.

  • Is it possible to disable the retry mechanism in Exim

    - by Tony Meyer
    I have a very simple Exim configuration that's just forwarding all mail to a set of destination addresses. When immediate delivery to an address fails, the message is added to the queue (and then processed by the retry rules). I want to change this so that if immediately delivery fails, the message is :blackhole:d. (It's ok if a bounce is generated instead, as I'll just redirect the bounce to the :blackhole:). This needs to occur for temporary failures (i.e. 4xx) as well as permanent (i.e. 5xx) ones. I understand that this means that if delivery can't be done immediately the message will be permanently and irretrievably lost. In this particular context, that isn't a problem. Reading over this, it sounds suspiciously like "how can I improve my spamming Exim server". That really isn't what this is for, and if you can figure out a way I can prove that, I'm happy to do so!

  • Why is my firewall preventing me from accessing some websites

    - by nosx
    I have an old Belkin router and when I enable the firewall I cannot access certain websites. For example: http://www.avisynth.org With Firewall Enabled: Main page loads and begins to do a meta refresh which never finishes. With Firewall Disabled: Main page loads and the meta refresh completes as normal and I am taken to the wiki page. I have not setup any rules in my firewall that would prevent this site from loading, yet it refuses to load unless I have the firewall disabled completely. My router has a hidden page with advanced settings on it for the firewall which I was able to acccess and take a screenshot of, but I did not want to mess with these values unless I absolutely have to do so: What might be causing this problem and how would I go about fixing it?

  • How to copy directories using debugfs?

    - by tjbp
    The debugfs manpage gives the impression that the command 'rdump . .' will recursively copy all files found on the specified filesystem from the debugfs cwd to the native filesystem's cwd. Instead I seem to receive a syntax error, and no copy is initiated? These are the commands I run: cd /path/to/transfer/destination debugfs /dev/sda1 -R rdump . . My task is to copy the entire contents of a clean yet unmountable USB storage device to its host machine's HD. The host machine does not support the inode size used by the USB device's filesystem (256) and its software is not upgradeable, so my intention was to use debugfs to transfer the files. If anyone has any other suggestions for this task I'd be grateful.
