  • Passing two arguments to a command using pipes

    - by firebat
    Usually, we only need to pass one argument: echo abc | cat echo abc | cat some_file - echo abc | cat - some_file Is there a way to pass two arguments? Something like {echo abc , echo xyz} | cat cat `echo abc` `echo xyz` I could just store both results in a file first echo abc > file1 echo xyz > file2 cat file1 file2 But then I might accidentally overwrite a file, which is not ok. This is going into a non-interactive script. Basically, I need a way to pass the results of two arbitrary commands to cat without writing to a file. UPDATE: Sorry, the example masks the problem. While { echo abc ; echo xyz ; } | cat does seem to work, the output is due to the echos, not the cat. A better example would be { cut -f2 -d, file1; cut -f1 -d, file2; } | paste -d, which does not work as expected. With file1: a,b c,d file2: 1,2 3,4 Expected output is: b,1 d,3 RESOLVED: Use process substitution: cat <(command1) <(command2) Alternatively, make named pipes using mkfifo: mkfifo temp1 mkfifo temp2 command1 > temp1 & command2 > temp2 & cat temp1 temp2 Less elegant and more verbose, but works fine, as long as you make sure temp1 and temp2 don't exist before hand.

  • SNMPD - passing values in a trap

    - by ethrbunny
    Im trying to create an SNMP setup to monitor 500-1K machines. Each will be joined to the SNMPTRAPD server via a VPN. When the client system sends its messages, it's sending its internal address instead of the VPN address even though the 'trapsync' command is using the VPN. This will be a problem as many of these system will have DHCP addresses based on location so there will be overlap. What I'd like to figure out is how to pass extra values with the trap so I can identify which system a given trap comes from.

  • Passing all traffic through Cloudflare

    - by Nick
    I am new to Linux System Administration and I am experimenting with iptables trying to learn how to really lock down a system with them. And one thing a friend of mine recommended was that there was a way to pass all incoming traffic through Cloudflare so even if attackers resolved the server ip they still couldn't (D)dos it directly. This is exactly what they said: "Simply config your servers iptables to only allow incoming connections from CloudFlares IP ranges then set it to allow only your IP/IP range to connect on port 21 (SSH)" Could someone help me on what command I'd need to run for Ubuntu to get this effect?

  • Linux Kernel not passing through multicast UDP packets

    - by buecking
    Recently I've set up a new Ubuntu Server 10.04 and noticed my UDP server is no longer able to see any multicast data sent to the interface, even after joining the multicast group. I've got the exact same set up on two other Ubuntu 8.04.4 LTS machines and there is no problem receiving data after joining the same multicast group. The ethernet card is a Broadcom netXtreme II BCM5709 and the driver used is: b $ ethtool -i eth1 driver: bnx2 version: 2.0.2 firmware-version: 5.0.11 NCSI 2.0.5 bus-info: 0000:01:00.1 I'm using smcroute to manage my multicast registrations. b$ smcroute -d b$ smcroute -j eth1 233.37.54.71 After joining the group ip maddr shows the newly added registration. b$ ip maddr 1: lo inet 224.0.0.1 inet6 ff02::1 2: eth0 link 33:33:ff:40:c6:ad link 01:00:5e:00:00:01 link 33:33:00:00:00:01 inet 224.0.0.1 inet6 ff02::1:ff40:c6ad inet6 ff02::1 3: eth1 link 01:00:5e:25:36:47 link 01:00:5e:25:36:3e link 01:00:5e:25:36:3d link 33:33:ff:40:c6:af link 01:00:5e:00:00:01 link 33:33:00:00:00:01 inet 233.37.54.71 <------- McastGroup. inet 224.0.0.1 inet6 ff02::1:ff40:c6af inet6 ff02::1 So far so good, I can see that I'm receiving data for this multicast group. b$ sudo tcpdump -i eth1 -s 65534 host 233.37.54.71 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65534 bytes 09:30:09.924337 IP 192.164.1.120.58848 > 233.37.54.71.15572: UDP, length 212 09:30:09.947547 IP 192.164.1.120.58848 > 233.37.54.71.15572: UDP, length 212 09:30:10.108378 IP 192.164.1.120.58866 > 233.37.54.71.15574: UDP, length 268 09:30:10.196841 IP 192.164.1.120.58848 > 233.37.54.71.15572: UDP, length 212 ... I can also confirm that the interface is receiving mcast packets. b $ ethtool -S eth1 | grep mcast_pack rx_mcast_packets: 103998 tx_mcast_packets: 33 Now here's the problem. When I try to capture the traffic using a simple ruby UDP server I receive zero data! Here's a simple server that reads data send on port 15572 and prints the first two characters. This works on the two 8.04.4 Ubuntu Servers, but not the 10.04 server. require 'socket' s = UDPSocket.new s.bind("", 15572) 5.times do text, sender = s.recvfrom(2) puts text end If I send a UDP packet crafted in ruby to localhost, the server receives it and prints out the first two characters. So I know that the server above is working correctly. irb(main):001:0> require 'socket' => true irb(main):002:0> s = UDPSocket.new => #<UDPSocket:0x7f3ccd6615f0> irb(main):003:0> s.send("I2 XXX", 0, 'localhost', 15572) When I check the protocol statistics I see that InMcastPkts is not increasing. While on the other 8.04 servers, on the same network, received a few thousands packets in 10 seconds. b $ netstat -sgu ; sleep 10 ; netstat -sgu IcmpMsg: InType3: 11 OutType3: 11 Udp: 446 packets received 4 packets to unknown port received. 0 packet receive errors 461 packets sent UdpLite: IpExt: InMcastPkts: 4654 <--------- Same as below OutMcastPkts: 3426 InBcastPkts: 9854 InOctets: -1691733021 OutOctets: 51187936 InMcastOctets: 145207 OutMcastOctets: 109680 InBcastOctets: 1246341 IcmpMsg: InType3: 11 OutType3: 11 Udp: 446 packets received 4 packets to unknown port received. 0 packet receive errors 461 packets sent UdpLite: IpExt: InMcastPkts: 4656 <-------------- Same as above OutMcastPkts: 3427 InBcastPkts: 9854 InOctets: -1690886265 OutOctets: 51188788 InMcastOctets: 145267 OutMcastOctets: 109712 InBcastOctets: 1246341 If I try forcing the interface into promisc mode nothing changes. At this point I'm stuck. I've confirmed the kernel config has multicast enabled. Perhaps there are other config options I should be checking? b $ grep CONFIG_IP_MULTICAST /boot/config-2.6.32-23-server CONFIG_IP_MULTICAST=y Any thoughts on where to go from here?

  • Passing a file with multiple patterns to grep

    - by Michael Goldshteyn
    Let's say we have two files. match.txt: A file containing patterns to match: fed ghi tsr qpo data.txt: A file containing lines of text: abc fed ghi jkl mno pqr stu vwx zyx wvu tsr qpo Now, I want to issue a grep command that should return the first and third line from data.txt: abc fed ghi jkl zyx wvu tsr qpo ... because each of these two lines match one of the patterns in match.txt. I have tried: grep -F -f match.txt data.txt but that returns no results. grep info: GNU grep 2.6.3 (cygwin) OS info: Windows 2008 R2 Update: It seems, that grep is confused by the space in the search pattern lines, but with the -F flag, it should be treating each line in match.txt as an individual match pattern.

  • WinPE, Startnet.CMD and passing variables to second batch file not working

    - by user140892
    I don't know scripting or PowerShell (yes I need to learn something). I'm not an expert batch file maker either. I have a WinPE flash drive which I used to deploy OS images. I have the WIM, drivers and anything needed else outside the WinPE environment to ensure that Updates, changes are easier for me to make. I use the "STARTNET.CMD" batch file which is part of the WinPE. The reason to go through the letter drives is that the WinPE always gets the X letter drive assigned. The flash drive itself can receive a random letter which always changes. My deployment menu is located on the flash drive it self and not inside the WinPE. This is so that if I need to make a change I don't have to re-do the WinPE. I am able to locate the "menu.bat" batch file and launch it. I use a variable to capture the letter drive. I call the second batch file named "menu.bat" and pass the variable to it. When the second batch file loads, I believe that I am calling the variable correctly. If I break out of the batch file I can echo the variable and see the expected reply. The issue is that I can't use the variable to work with anything on the second batch file. In my test, I can get this to work over and over. When it runs from the real USB flash drive it does not work. I removed comments from the second batch file to make it smaller. My issue is that files below all get a message stating that the system cannot find the path specified. Diskpart Imagex.exe bcdboot.exe Why can't I get the varible to properly function when I try to using example "ImageX.exe"?

  • Cisco PIX 515 doesn't seem to be passing traffic through according to static route

    - by Liquidkristal
    Ok, so I am having a spot of bother with a Cisco PIX515, I have posted the current running config below, now I am no cisco expert by any means although I can do basic stuff with them, now I am having trouble with traffic sent from the outside to address: 10.75.32.25 it just doesn't appear to be going anywhere. Now this firewall is deep inside a private network, with an upstream firewall that we don't manage. I have spoken to the people that look after that firewall and they say they they have traffic routing to 10.75.32.21 and 10.75.32.25 and thats it (although there is a website that runs from the server 172.16.102.5 which (if my understanding is correct) gets traffic via 10.75.32.23. Any ideas would be greatly appreciated as to me it should all just work, but its not (obviously if the config is all correct then there could be a problem with the web server that we are trying to access on 10.75.32.25, although the users say that they can get to it internally (172.16.102.8) which is even more confusing) PIX Version 6.3(3) interface ethernet0 auto interface ethernet1 auto

  • Postfix removing domain from user names before passing to Dovecot for IMAP authentication

    - by chernevik
    In IMAP authentication with Dovecot, Postfix is stripping the domain name from virtual users who share a name with a local user, causing them to fail authentication. Virtual users without local accounts don't have this problem. How can I prevent this? Failing an answer, how can I debug Postfix to see what's going on? I've turned on every debugging option I can get, and I'm not seeing anything helpful in the logs.

  • kvm -net only passing broadcast, multicast, and guest destination traffic

    - by user52874
    Figured this out just last week, but I can't find it now. Even printed it out. Can't find that either. Frustrating...so...help! Configured a 'monitoring' nic on a kvm guest (running 'Security Onion, if it matters). I read (somewhere) that the default nic configuration for a kvm guest is to only pass broadcast traffic, multicast traffic, and traffic with the guest's mac as a destination. There is an option to override this behaviour, and pass all traffic. It's something like --mac-filtering=no, or --mac-restriction=no, or something like that. Worked beautifully. Does this look at all familiar to anyone who can clue me in to the exact option syntax? thx.

  • Passing parameters to a shell script running as a cronjob

    - by Takashi
    I am new to bash scripting (not programming in general). I am writing a bash script that will run a Python script I have written. I want to be able to do the following: Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo' switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).

  • Doing arithmetic and passing it to the next command

    - by neurolysis
    I know how to do this in /bin/sh, but I'm struggling a bit in Windows. I know you can do arithmetic on 32-bit signed integers with SET /a 2+2 4 But how do I pass this to the next command? For example, the process I want to perform is as follows. Consumer editions of Windows have no native automated sleep function (I believe?) -- the best way to perform a sleep is to use PING in association with the -n switch to get that many seconds, minus one, of sleep. The following command is effective for a silent sleep: PING localhost -n 3 > NUL But I want to alias this into a sleep command. I'd like to have it elegant so that you enter the actual number of seconds you want to sleep after the command, right now I can do DOSKEY SLEEP=PING 127.0.0.1 -n $1 > NUL Which works, but it's always 1 second less than your input, so if you wanted to sleep for one second you would have to use the command SLEEP 2. That's not exactly ideal. Is there some way for me to pass the arithmetic of $1+1 and pass it on to the next command in Windows? I assume there is some way of using STDOUT...

  • Passing multiple sets of arguments to a command

    - by Alec
    instances contains several whitespace separated strings, as does snapshots. I want to run the command below, with each instance-snapshot pair. ec2-attach-volume --instance $instances --device /dev/sdf $snapshots For example, if instances contains A B C, and snapshots contains 1 2 3, I want the command to be called like so: ec2-attach-volume -C cert.pem -K pk.pem --instance A --device /dev/sdf 1 ec2-attach-volume -C cert.pem -K pk.pem --instance B --device /dev/sdf 2 ec2-attach-volume -C cert.pem -K pk.pem --instance C --device /dev/sdf 3 I can do either one or the other with xargs -n 1, but how do I do both?

  • Remote network traffic not passing through VPN

    - by John Virgolino
    We have the following topology: LAN A LAN B LAN C 10.14.0.0/16 <-VPN-> 10.18.0.0/16 --- SONICWALL <-VPN-> M0N0WALL --- 10.32.0.0/16 Traffic between LAN A and LAN B works perfectly. Traffic between LAN C and LAN B works perfectly. Traffic between LAN A and LAN C, not so much. LAN A's gateway has a route to LAN C that points to the Sonicwall. The Sonicwall has a route to LAN A pointing to the VPN gateway connecting LAN B to LAN A. Tracing packets on the Sonicwall shows the LAN C destined traffic to arrive on the Sonicwall, but it does not forward the traffic, it dies there. Traffic from LAN B gets forwarded. Tracing packets on the Sonicwall while sending traffic from LAN C destined for LAN A shows nothing. This tells me that the M0N0WALL is not forwarding traffic for the 10.14.0.0 network and the Sonicwall is not forwarding from 10.14.0.0. The SA on the Sonicwall terminates on the WAN ZONE and is defined to use an address group that incorporates both the 10.14.0.0 and 10.18.0.0 networks. The M0N0WALL is configured for the 10.18.0.0 network and I have tried with both a static route to 10.14.0.0 and without on the M0N0WALL. I tried manually adding the 10.14.0.0 network to the SA on the M0N0WALL, but that really aggravated it and the SA never came up, so I reverted. I have checked all the firewall rules to make sure nothing is blocked. All of the Sonicwall auto-added rules look right. Specs: Sonicwall TZ200, Enhanced OS M0N0WALL v1.32 I'm at a loss at this point. Any help would be appreciated.

  • Asterisk Dial() - passing URL to softphone

    - by Giuc
    According to https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+Application_Dial the Dial() application is capable of sending an URL to the extension being called. I suppose there are softphones implementing this, maybe popping up a browser pointing to the given URL - perfect to open up automatically a CRM customer page when receiving a call by identifying his caller id. Do you know of any softphone implementing this functionality?

  • Rails link to current page and passing parameters to it

    - by Faisal
    I am adding I18N to my rails application by passing the locale using url params. My urls are looking like http://example.com/en/users and http://example.com/ar/users (for the english and arabic locales respectively). In my routes file, I have defined my routes with a :path_prefix option: map.resources :users, :path_prefix => '/:locale' And locale is being set using a before_filter defined in ApplicationController def set_locale I18n.locale = params[:locale] end I also defined ApplicationController#default_url_options, to add locale to all urls generated by the application: def default_url_options(options={}) {:locale => I18n.locale} end What I want is to add a link in the layout header (displayed in all pages) that would link to the same page but with the other locale. For instance, if I am browsing the arabic locale, I want a "English" link in the header, that will redirect me back to my current page, and set the locale to english. Is there a way to do this in rails?

    Hello all, I've got a chunk of code that's passing an NSMutableDictionary (amongst other things) to a method in another class: [self.shuttle makeAPICallAndReturnResultsUsingMode:@"login" module:@"login" query:credentials]; The NSMutableArray credentials is previously defined like this: NSMutableDictionary *credentials = [[NSMutableDictionary alloc] init]; [credentials setObject:username forKey:@"username"]; [credentials setObject:password forKey:@"password"]; The method that receives it looks like this: -(id)makeAPICallAndReturnResultsUsingMode:(NSString *)mode module:(NSString *)module query:(NSMutableDictionary *)query The code works fine up until this point within the above method: [query setObject:self.sessionID forKey:@"session_id"]; At this point, the application terminates -- the console informs me of this exception: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSCFDictionary setObject:forKey:]: method sent to an uninitialized mutable dictionary object' This leads me to believe that I must initialize NSMutableDictionary in some way in my new method before I can access it, but I have no idea how. Any advice?

  • Enthought Canopy - passing sys.argv from PySide Qt program

    - by user2541559
    I've recently been looking at the Enthought distro of iPython. Today I decided to see if I could get some Qt GUI progs running and was successful after making minor changes. Simple example: import sys from PySide import QtGui # was 'from PyQT4 import QtGui' # app = QtGui.QApplication(sys.argv) -- not needed win = QtGui.QWidget() win.resize(320, 240) win.setWindowTitle("Hello MIT 6X!") win.show() sys.exit() # was 'sys.exit(app.exec_())' But I would like to be able to pass sys.argv in some cases. Most example code I see is in the form of the commented out 'app = ' line above. If I include it, I get 'RuntimeError: A QApplication instance already exists.' Suggestions for passing arguments appreciated. Nick

  • Problem passing json into jquery graph(flot)

    - by Adam McMahon
    I trying to retrieve some json to pass into a flot graph. I know that json is right because I hard coded it to check, but I'm pretty sure that I'm not passing right because It's not showing up. Here's the javascript: var total = $.ajax({ type: "POST", async: false, url: "../api/?key=xxx&api=report&crud=return_months&format=json" }).responseText; //var total = $.evalJSON(total); var plot = $.plot($("#placeholder"),total); here's the json: [ { data: [[1,12], [2,43], [3,10], [4,17], ], label: "E-File"}, { data: [[1,25], [2,35], [3,3], [4,5], ], label: "Bank Products" }, { data: [[1,41], [2,87], [3,30], [4,29], ], label: "All Returns" } ], {series: {lines: { show: true },points: { show: true }}, grid: { hoverable: true, clickable: true }, yaxis: { min: 0, max: 100 }, xaxis: { ticks: [[1,"January"],[2,"February"],[3,"March"],[4,"April"],[5,"May"],[6,"June"],[7,"July"],[8,"August"],[9,"September"],[10,"October"],[11,"November"],[12,"December"]] }}

  • Passing to service custom class instance in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. _ Public Class Customer Private Type_of_clientField As Integer = -1 _ Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class _ _

  • PHP Session variables not passing across pages

    - by mitch
    Common problem, but I'm stumped. Session variables are passing across pages on my local (localhost) deployment, but not on my (www) host. I use a common includes file for each page with this code: $sessionDomain = "/"; @ini_set("session.cookie_path",$sessionDomain); $sessionName = "ccSID".md5('/store/'); session_name($sessionName); session_start(); I confirmed that the session ID cookie (ccSIDxxxxx...) remains the same across pages in my browser, but session variables don't seem to hold up when changing to a page in a different directory.
