  • Port binding conflicts with "switch user" on Windows 7

    - by C-dizzle
    We are using the switch user function within Windows 7 under an active directory network. We have one application in particular that gives us an error: Only one usage of each socket address (protocol/network address/port) is normally permitted. bind Port 10001 Are there any other ports that can only be used at one time that might have an adverse effect on the other user? We try to mentor our users to use the log off function instead of switch user, but that doesn't always happen. As an alternative, is it possible to disable the 'switch user' button on our machines?

  • How to bind Apache to specific IP and port on Windows Server 2008

    - by webworm
    I have a Windows Server 2008 R2 that I use to host various ASP.NET applications under IIS7. I would also like to run various PHP based web apps using Apache (or Apache 2). The server has three static IP addresses assigned to it and I would like to bind one of the IP addresses to Apache while using the other two IP addresses for IIS. I can use the IIS Manager to bind the specific IP addresses to IIS, but I am unaware of how to do this with Apache. Can anyone tell me how to go about binding Apache to a specific IP address and port (port 80 is what I want to use). Please note .. I am aware that PHP can run under IIS. In fact that is how I have been running my PHP web applications. However, there are so many inconsistencies and pitfalls with PHP running under IIS that I just prefer to use Apache.

  • Configuring a Jetty web application on a different port

    - by sHz
    Hi folks, I'm brand new to Jetty. I'd like to ask if its possible to have Jetty listening on port 8080, however where specified, serve a specific web application under say /var/jetty/webapps/<appname> (default on CentOS) served on say port 10000 instead of http://localhost:8080/<appname> i.e. http://localhost:10000/ = http://localhost:8080/<appname&gt; ? If so, what configuration changes would be required to make this work without an additional proxy server? I've googled away, but haven't found a solution (perhaps I've missed something obvious?).

  • openwrt uses a single interface bridge?

    - by timbo
    My understanding of bridging is that it ties together two interfaces at layer 2. I am looking at a Ubiquiti Nanostation2 running OpenWRT that has an ethernet port 'eth0' and a wifi port 'ath0'. The ethernet port (the 'wan' port) is not part of the bridge and the bridge is just a single interface. Can anyone clarify this? - seems very different to Ubuntu. /etc/config/network: config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'wan' option 'ifname' 'eth0' option 'proto' 'dhcp' config 'interface' 'wifi' option 'ipaddr' '192.168.13.1' option 'type' 'bridge' option 'proto' 'static' option 'netmask' '255.255.255.0' option 'ifname' 'wifi0'

  • route port 3000 to apache2 alias

    - by user223470
    I have a meteor application running on port 3000. I can successfully connect to the program with www.myurl.com:3000, but would rather connect to it via www.myurl.com/myappname. I started with the instructions on this web site: http://www.andrehonsberg.com/article/deploy-meteorjs-vhosts-ubuntu1204-mongodb-apache-proxy and I have the following Apache configuration file: <VirtualHost *:80> ServerName myurl.com ProxyRequests off <Proxy *> Order deny,allow Allow from all </Proxy> <Location /> ProxyPass http://localhost:3000/ ProxyPassReverse http://localhost:3000/ </Location> </VirtualHost> I do not know how to continue from here to get the program on www.mysite.com/myapp. In other situations, I would use an Alias within the Apache configuration file, but that doesn't seem like the right direction to go in this case. How do I configure Apache to send port 3000 to www.myurl.com/myapp?

  • How to mmap the stack for the clone() system call on linux?

    - by Joseph Garvin
    The clone() system call on Linux takes a parameter pointing to the stack for the new created thread to use. The obvious way to do this is to simply malloc some space and pass that, but then you have to be sure you've malloc'd as much stack space as that thread will ever use (hard to predict). I remembered that when using pthreads I didn't have to do this, so I was curious what it did instead. I came across this site which explains, "The best solution, used by the Linux pthreads implementation, is to use mmap to allocate memory, with flags specifying a region of memory which is allocated as it is used. This way, memory is allocated for the stack as it is needed, and a segmentation violation will occur if the system is unable to allocate additional memory." The only context I've ever heard mmap used in is for mapping files into memory, and indeed reading the mmap man page it takes a file descriptor. How can this be used for allocating a stack of dynamic length to give to clone()? Is that site just crazy? ;) In either case, doesn't the kernel need to know how to find a free bunch of memory for a new stack anyway, since that's something it has to do all the time as the user launches new processes? Why does a stack pointer even need to be specified in the first place if the kernel can already figure this out?

  • User Friendly port knocker (port knocking client) for Windows?

    - by Ekevoo
    It seems "It's me" is the most popular port knocking client for windows… Except… it sucks. It works for console-savvy users such as me, but, unsurprisingly, all my users hate console windows. I know better than to force it upon them. I would love to have a nice port knocker for Windows that would be windowed, have launchers, and be easily provisionable (i.e. I tell my user to paste some settings or import some file by double clicking it). To be honest, just not being console-based would be enough.

  • nginx + varnish + apache differente IPs in VirtualHost Apache

    - by zeusgod
    Hi, My idea is put NGINX as proxy to redirect to Varnish (cache static content) and then proxy to apache with a lot of VirtualHost in different IPs. My problems is that I would know how can configure Varnish to send access to correct IP, I am going explain: NGINX: Listen in: 10.10.10.10, 20.20.20.20 and 30.30.30.30 on ports: 80 and 443 Proxy redirect to Varnish 10.10.10.10:8080, 20.20.20.20:8080 and 30.30.30.30:8080 Varnish: Port: 8080 - THIS IS THE PROBLEM Proxy content not static to Apache on port 8000 - THIS IS THE OTHER PROBLEM Apache2: Listen in: 10.10.10.10:8000, 20.20.20.20:8000 and 30.30.30.30:8000 Response correct VirtualHost This is the idea. When I try with one IP only, all work correctly, because Varnish is only listen in one IP and port and send to backend in one IP and port too. Could you help me to configure Varnish or there is a best way to configure similar scenario please?

  • Specifying --host1 as localhost with port 8983 in autobench

    - by mamatha
    I am using autobench for benchmarking in ubuntu 8.10 autobench --single_host --host1 localhost --uri1 /solr/admin --low_rate 20 --high_rate 200 --rate_step 20 --num_call 10 --num_conn 5000 --timeout 5 --file bench1.tsv This is the command which I gave. It is taking the default port as 80 and the number of replies and requests are as shown below **Errors: total 5000 client-timo 0 socket-timo 0 connrefused 5000 connreset 0 Errors: fd-unavail 0 addrunavail 0 ftab-full 0 other 0 Zero replies received, test invalid: rate 20 httperf --timeout=5 --client=0/1 --server=localhost --port=80 --uri=/solr/admin --rate=40 --send-buffer=4096 --recv-buffer=16384 --num-conns=5000 --num-calls=10 Maximum connect burst length: 4 Total: connections 5000 requests 0 replies 0 test-duration 124.976 s** But, I want the port to be 8983. In all the examples that I have seen in the autobench tutorial, --host1 is a website (such as, www.test.com). Can anyone suggest how to use localhost taking the port as 8983? Thanks, in advance.

  • How to monitor traffic on certain ports with ntop

    - by Claudiu
    How to configure ntop so I can get the amount of upload traffic sent through a certain port ? I've added port in ntop/protocol.list, restarted ntop and after some time I've checked Summary - Traffic - TCP/UDP Traffic Port Distribution: Last Minute View, but data from that table is not too relevant. I think there is much more about this ntop that I don't know (configuration, usage).

  • Single-port 2600 router with 2900XL switch

    - by Slava Maslennikov
    I have a setup, where the single port 2600 router is in port 0/2 in the switch, outside network is on port 0/1, and the rest (0/3-0/24) should be clients for the second network that would be managed by the 2600 router. I configured everything with two VLANs: 100 for outside (0/2-0/24), 200 for inside (0/1-0/2). 0/2 is a trunk port for the two VLANs. The issue that came about is that I can't have two VLANs on at once: software doesn't allow it. Now, I can ping the outside network devices (172.16.7.1, 172.16.7.103), and even google (8.8.8.8) from the router, but not the switch. Devices on connected get a DHCP lease properly but can't ping outside the network, just the router - 172.17.7.1 and the switch itself, 172.17.7.7. The configuration for both the router and the switch are here, as well as below. Router: rt.throom#sho run Building configuration...

  • How can I simulate blocking RTMP over port 80 on Windows?

    - by Christian Nunciato
    It seems like this should be so simple, but since this isn't my area of expertise, I'm having a hell of a time figuring out how to do it. Basically, I have a Flash app and I'm connecting to a Flash Media Server to stream some content. The URL I'm using to do this, for example, looks like this: rtmp://someserver.com/some/path/mp3:somefile Everything works -- but that's sort of the problem. When I'm trying to do is simulate my users attempting to play back my media under more restrictive conditions than the ones I have here (i.e., none) -- namely being stuck behind firewalls or proxy servers that block access to RTMP streams. Flash, according to Adobe, is equipped to handle proxy servers and firewalls automatically, like so (from the docs): When you do not specify a port number in an RTMP address, Flash will attempt to connect to port 1935. If it fails it will then try to connect to port 443; if that fails, it will try port 80. [And if that fails, it will attempt to connect via RTMPT (i.e., HTTP tunneling) on port 80.] So no coding is required to access ports 1935, 443, or port 80 if you do not specify a port in the RTMP address. The problem I'm having is setting up a reliable environment in which to test that this behavior actually happens. I'm on a Windows machine, for example, so with Windows Firewall, I can block certain ports and protocols (1935, 443), but I don't want to block port 80, because the final fallback protocol (RTMPT) is supposed to run on port 80, and Windows Firewall only gives me enough granularity (as far as I know, anyway) to block "all outbound TCP traffic to remote port 80" -- that is, I can't, apparently, block "all outbound RTMP traffic to port 80" while leaving RTMPT traffic to port 80 unaffected. My understanding thus far is that I'll probably need to set up a proxy server to do this. Is this correct? Or is there a simpler way (on Win 7, at least) to filter out RTMP to 1935, RTMP to 443, RTMP to 80, but still allow RTMPT to 80 (where all four hostnames are identical)? And if I do have to set up a proxy server, what's the simplest way to go on Windows? I've set up WinProxy, which seems a bit janky but apparently works -- but then what I can't figure out is how to tell Windows to force all TCP traffic (including RTMP, RTMPT and HTTO) through this proxy server so I can turn around and reject the requests for RTMP. Any help would be hugely appreciated. This isn't my realm of expertise and I've alreasdy spent more time on it than I probably should. :)

  • Is opening ports in the firewall bad?

    - by Steven
    From what little I know about networking, opening ports lets external data get sent in. But how that data is handled is entirely up to the applications running on my machine. So if I'm not running any malicious applications, there should be nothing wrong with disabling the firewall, right? Also, how do applications work when ports aren't forwarded? For example, I need to forward port TCP 6112 to host Blizzard games, but I've heard that HTTP uses port 80, but I haven't forwarded that port, yet Firefox still works. Btw I'm using Windows Vista.

  • Configure Windows firewall to prevent an application from listening on a specific port [closed]

    - by U-D13
    The issue: there are many applications struggling to listen on port 80 (Skype, Teamviewer et al.), and to many of them that even is not essential (in the sense that you can have a httpd running and blocking the http port, and the other application won't even squeak about being unable to open the port). What makes things worse, some of the apps are... Well, I suppose, that it's okay that the mentally impaired are being integrated in the society by giving them a job to do, but... Programming requires some intellectual effort, in my humble opinion... What I mean is that there is no way to configure the app not to use specific ports (that's what you get for using proprietary software) - you can either add it to windows firewall exceptions (and succumb to undesired port opening behavior) or not (and risk losing most - if not all - of the functionality). Technically, it is not impossible for the firewall to deny an application opening an incoming port even if the application is in the exception list. And if this functionality is built into the Windows firewall somewhere, there should be a way to activate it. So, what I want to know is: whether there exists such an option, and if it does how to activate it.

  • Grepping grep output fails

    - by viraptor
    I'm trying to grep the output of ngrep. Unfortunately when I add another grep to the pipeline, I get no output at all. It can be some other command too - cat / grep / tee - everything breaks the chain. Example: # this works: $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' -- U +1.469535 xxx:5060 -> xxx:5060 SIP/2.0 180 Ringing. -- U +0.001384 xxx:5060 -> xxx:2048 SIP/2.0 180 Ringing. but #these don't: $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' | egrep '^U' $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' | cat $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' | tee test If I use cat somefile instead of ngrep at the start, everything works as expected. Any ideas what could go wrong here?

  • Dual WAN port on a WRT54GL

    - by pufferfish
    Is it possible to reconfigure one of the LAN ports on a WRT54GL (running Tomato firmware) to act as a second WAN port? I have the following networks: PPOE connection to ADSL modem (works fine on the normal WAN port) WiFi neighbourhood network (in 178.X.X.X range), via a Mikrotik routerboard which I'd like to put on the WAN side of the router. I'd then like to set up routing so than some traffic (172.X.X.X) is routed to the Mikrotik and the rest to the ADSL modem. p.s. for practical reasons, I can't use the Mikrotik as the firewall/router. Edit: It seems this can be done by editing iptables, can someone tell me exactly how?

  • Howto configure openSuSE firewall to route local traffic to local ports

    - by Eduard Wirch
    I have openSUSE 11.3 installed. I'm using the openSUSE firewall configuration mechanism (/etc/sysconfig/SuSEfirewall2). I have a http server application running on port 8080. I want the http service to be accessible using port 80. I created a redirect rule usign: FW_REDIRECT="0/0,0/0,tcp,80,8080" This works fine for every request coming from external. But it doesn't for local requests. (example: wget http://myserver/) Is there a way how I can tell the firewall to redirect local requests addressed for 80 to port 8080? (using the SUSE firewall configuration file)

  • Cannot assign port 4 to WAN on TP-Link WR740N by DD-WRT wiki

    - by Victor Sergienko
    I'm following the DD-WRT instruction to get TP-Link WR740N v3's Port 4 on a different VLAN, but this doesn't happen. First, I have no "Setup VLANs" settinngs tab in DD-WRT v24-sp2 (07/20/12) std r19519. I can get Internet on Wi-Fi if assigning eth1 to "WAN Port", but then all Ethernet ports get on the same VLAN and any wired connection grabs the DHCP address and Internet connection from router. When following the "old" instruction, if I run, say, nvram set vlan2ports="2 5*", should there appear a new interface, vlan2, in ifconfig, after ifconfig vlan2 up? It doesn't - does it mean there is no support for different VLANs in my software/hardware? What am I missing? Is it impossible to create more VLANs on TP-Link740?

  • How to create partition when growing raid5 with mdadm.

    - by hometoast
    I have 4 drives, 2x640GB, and 2x1TB drives. My array is made up of the four 640GB partitions and the beginning of each drive. I want to replace both 640GB with 1TB drives. I understand I need to 1) fail a disk 2) replace with new 3) partition 4) add disk to array My question is, when I create the new partition on the new 1TB drive, do I create a 1TB "Raid Auto Detect" partition? Or do I create another 640GB partition and grow it later? Or perhaps the same question could be worded: after I replace the drives how to I grow the 640GB raid partitions to fill the rest of the 1TB drive? fdisk info: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe3d0900f Device Boot Start End Blocks Id System /dev/sdb1 1 77825 625129281 fd Linux raid autodetect /dev/sdb2 77826 121601 351630720 83 Linux Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc0b23adf Device Boot Start End Blocks Id System /dev/sdc1 1 77825 625129281 fd Linux raid autodetect /dev/sdc2 77826 121601 351630720 83 Linux Disk /dev/sdd: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x582c8b94 Device Boot Start End Blocks Id System /dev/sdd1 1 77825 625129281 fd Linux raid autodetect Disk /dev/sde: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xbc33313a Device Boot Start End Blocks Id System /dev/sde1 1 77825 625129281 fd Linux raid autodetect Disk /dev/md0: 1920.4 GB, 1920396951552 bytes 2 heads, 4 sectors/track, 468846912 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000
