  • How to open a text file that's not in the same folder?

    - by nunos
    Since C it's not a language I am used to program with, I don't know how to do this. I have a project folder where I have all the .c and .h files and a conf folder under which there is a config.txt file to read. How can I open that? FILE* fp = fopen("/conf/config.txt"); if (fp != NULL) { //do stuff } else printf("couldn't open file\n"); I keep getting the error message. Why? Thanks.

  • How do I do this in Python (File Manipulation)?

    - by ThinkCode
    I have a bunch of HTML files in HTML folder. Those HTML files have unicode characters which I solved by using filter(lambda x: x in string.printable, line). Now how do I write the changes back to the original file? What is the best way of doing it? Each HTML file is of 30 kb in size. 1 import os, string 2 3 for file in os.listdir("HTML/"): 4 print file 5 myfile = open('HTML/' + file) 6 fileList = myfile.readlines() 9 for line in fileList: 10 #print line 11 line = filter(lambda x: x in string.printable, line) 12 myfile.close()

  • Reading line by line from a file in C

    - by mh234
    What I am trying to do is print out the contents of a file line by line. I run the program in terminal by doing: ./test testText.txt. When I do this, random characters are printed out but not what is in the file. The text file is located in the same folder as the makefile. What's wrong? #include <stdio.h> FILE *fp; int main(int argc, char *argv[]) { char line[15]; fp = fopen(*argv, "r"); while((fgets(line, 15, fp)) != NULL) { printf(line); printf("\n"); } }

  • Removing words from a file

    - by user1765792
    I'm trying to take a regular text file and remove words identified in a separate file (stopwords) containing the words to be removed separated by carriage returns ("\n"). Right now I'm converting both files into lists so that the elements of each list can be compared. I got this function to work, but it doesn't remove all of the words I have specified in the stopwords file. Any help is greatly appreciated. def elimstops(file_str): #takes as input a string for the stopwords file location stop_f = open(file_str, 'r') stopw = stop_f.read() stopw = stopw.split('\n') text_file = open('sample.txt') #Opens the file whose stop words will be eliminated prime = text_file.read() prime = prime.split(' ') #Splits the string into a list separated by a space tot_str = "" #total string i = 0 while i < (len(stopw)): if stopw[i] in prime: prime.remove(stopw[i]) #removes the stopword from the text else: pass i += 1 # Creates a new string from the compilation of list elements # with the stop words removed for v in prime: tot_str = tot_str + str(v) + " " return tot_str

  • Read All Files in Directory?

    - by cam
    How would I go about reading all files in a directory? In C# I would get a DirectoryInfo object, and get all files into a FileInfo[] object. Is there similar functionality in the STD namespace in C++?

  • BufferedInputStream.read(byte[]) Causes problems. Anyone have this problem before?

    - by K-RAN
    Hello! I've written a Java program that downloads audio files for me and I'm using BufferedInputStream. The read() function works fine but is really slow so I've tried using the overloaded version using byte[]. For some reason, the audio becomes lossy and strange after download. I'm not totally sure what I'm doing wrong so any help is appreciated! Here's the simplified, sloppy version of the code. BufferedInputStream bin = new BufferedInputStream((new URL(url)).openConnection().getInputStream()); File file = new File(fileName); FileOutputStream fop = new FileOutputStream(file); int rd = bin.read(); while(rd != -1) { fop.write(rd); rd = bin.read(); }

  • Why is this writing part of the text to a new line? (Python)

    - by whatsherface
    I'm adding some new bits to one of the lines in a text file and then writing it along with the rest of the lines in the file to a new file. Referring to the if statement, I that to be all on the same line: x = 13.55553e9 y = 14.55553e9 z = 15.55553e9 infname = 'afilename' outfname = 'anotherone' oldfile = open(infname) lnum=1 for line in oldfile: if (lnum==18): line = "{0:.2e}".format(x)+' '+line+' '+"{0:.2e}".format(y)+' '+ {0:.2e}".format(z) newfile = open(outfname,'w') newfile.write(line) lnum=lnum+1 oldfile.close() newfile.close() but y and z are being written on the line below the rest of it. What am I missing here?

  • Safely escaping and reading back a file path in ruby

    - by user336851
    I need to save a few informations about some files. Nothing too fancy so I thought I would go with a simple one line per item text file. Something like this : # write io.print "%i %s %s\n" % [File.mtime(fname), fname, Digest::SHA1.file(fname).hexdigest] # read io.each do |line| mtime, name, hash = line.scanf "%i %s %s" end Of course this doesn't work because a file name can contain spaces (breaking scanf) and line breaks (breaking IO#each). The line break problem can be avoided by dropping the use of each and going with a bunch of gets(' ') while not io.eof? mtime = Time.at(io.gets(" ").to_i) name = io.gets " " hash = io.gets "\n" end Dealing with spaces in the names is another matter. Now we need to do some escaping. note : I like space as a record delimiter but I'd have no issue changing it for one easier to use. In the case of filenames though, the only one that could help is ascii nul "\0" but a nul delimited file isn't really a text file anymore... I initially had a wall of text detailing the iterations of my struggle to make a correct escaping function and its reciprocal but it was just boring and not really useful. I'll just give you the final result: def write_name(io, val) io << val.gsub(/([\\ ])/, "\\\\\\1") # yes that' 6 backslashes ! end def read_name(io) name, continued = "", true while continued continued = false name += io.gets(' ').gsub(/\\(.)/) do |c| if c=="\\\\" "\\" elsif c=="\\ " continued=true " " else raise "unexpected backslash escape : %p (%s %i)" % [c, io.path, io.pos] end end end return name.chomp(' ') end I'm not happy at all with read_name. Way too long and akward, I feel it shouldn't be that hard. While trying to make this work I tried to come up with other ways : the bittorrent encoded / php serialize way : prefix the file name with the length of the name then just io.read(name_len.to_i). It works but it's a real pita to edit the file by hand. At this point we're halfway to a binary format. String#inspect : This one looks expressly made for that purpose ! Except it seems like the only way to get the value back is through eval. I hate the idea of eval-ing a string I didn't generate from trusted data. So. Opinions ? Isn't there some lib which can do all this ? Am I missing something obvious ? How would you do that ?

  • Erlang: How to view output of io:format/2 calls in processes spawned on remote nodes.

    - by jkndrkn
    Hello, I am working on a decentralized Erlang application. I am currently working on a single PC and creating multiple nodes by initializing erl with the -sname flag. When I spawn a process using spawn/4 on its home node, I can see output generated by calls io:format/2 within that process in its home erl instance. When I spawn a process remotely by using spawn/4 in combination with register_name, output of io:format/2 is sometimes redirected back to the erl instance where the remote spawn/4 call was made, and sometimes remains completely invisible. Similarly, when I use rpc:call/4, output of io:format/2 calls is redirected back to the erl instance where the `rpc:call/4' call is made. How do you get a process to emit debugging output back to its parent erl instance?

  • BizTalk &ndash; Routing failure on Delivery Notifications (BizTalk 2006 R2 to 2013)

    - by S.E.R.
    Originally posted on: http://geekswithblogs.net/SERivas/archive/2013/11/11/biztalk-routing-failure-on-delivery-notifications.aspxThis is a detailed explanation of a something I posted a few month ago on stackoverflow, concerning a weird behavior (a bug, really…) of the delivery notifications in BizTalk. Reminder: what are delivery notifications Mechanism BizTalk has the ability to automatically publish positive acknowledgments (ACK) when it has succeeded transmitting a message or negative acknowledgments (NACK) in case of a transmission failure. Orchestrations can use delivery notifications to subscribe to those ACKs and NACKs in order to know if a message sent on a one-way send port has been successfully transmitted. Delivery Notifications can be “activated” in two ways: The most common and easy way is to set the Delivery Notification property of a logical send port (in the orchestration designer) to Transmitted: Another way is to set the BTS.AckRequired context property of the message to be sent to true: NOTE: fundamentally, those methods are strictly equivalent since the fact of setting the Delivery Notification to Transmitted on the send port only tells BizTalk the BTS.AckRequired context property has to be set to true on the outgoing message. Related context properties ACKs and NACKs have a common set of propoted context properties, which are : Propriété Description AckType Equals ACK when successful or NACK otherwise AckID MessageID of the message concerned by the acknowledgment AckOwnerID InstanceID of the instance associated with the acknowledgment AckSendPortID ID of the send port AckSendPortName Name of the send port AckOutboundTransportLocation URI of the send port AckReceivePortID ID of the port the message came from AckReceivePortName Name of the port the message came from AckInboundTransportLocation URI of the port the message came from Detailed behavior The way Delivery Notifications are handled by BizTalk is peculiar compared to the standard behavior of the Message Box: if no active subscription exists for the acknowledgment, it is simply discarded. The direct consequence of this is that there can be no routing failure for an acknowledgment, and an acknowledgment cannot be suspended. Moreover, when a message is sent to a send port where Delivery Notification = Transmitted, a correlation set is initialized and a correlation token is attached to the message (Context property: CorrelationToken). This correlation token will also be attached to the acknowledgment. So when the acknowledgment is issued, it is automatically routed to the source orchestration. Finally, when a NACK is received by the source orchestration, a DeliveryFailureException is thrown, which can be caught in Catch section. Context of the problem Consider this scenario: In an orchestration, Delivery Notifications are activated on a One-Way send port In case of a transmission failure, the messaging instance is suspended and the orchestration catches an exception (DeliveryFailureException). When the exception is caught, the orchestration does some logging and then terminates (thanks to a Terminate shape). So that leaves only the suspended messaging instance, waiting to be resumed. Symptoms Once the problem that caused the transmission failure is solved, the messaging instance is resumed. Considering what was said in the reminder, we would expect the instance to complete, leaving no active or suspended instance. Nevertheless, the result is that the messaging instance is once more suspended, this time because of a routing failure: The routing failure report shows that the suspended message has the following attached properties: Explanation Those properties clearly indicate that the message being suspended is an acknowledgment (ACK in this case), which was published in the message box and was supended because no subscribers were found. This makes sense, since the source orchestration was terminated before we resumed the messaging instance. So its subscription to the acknowledgments was no longer active when the ACK was published, which explains the routing failure. But this behavior is in direct contradiction with what was said earlier: an acknowledgment must be discarded when no subscriber is found and therefore should not be suspended. Cause It is indeed an outright bug, which appeared with the SP1 of BizTalk 2006 R2 and was never corrected since then: not in the next 4 CUs, not in BizTalk 2009, not in 2010 and not event in 2013 – though I haven’t tested CU1 and CU2 for this last edition, but I bet there is nothing to be expected from those CUs (on this particular point). Side effects This bug can have pretty nasty side effects: this behavior can be propagated to other ports, due to routing mechanisms. For instance: you have configured the ESB Toolkit and have activated the “Enable routing failure for failed messages”. The result will be that the ESB Exception SQL send port will also try and publish ACKs or NACKs concerning its own messaging instances. In itself, this is already messy, but remember that those acknowledgments will also have the source correlation token attached to them… See how far it goes? Well, actually there is more: in SQL send ports, transactions will be rolled back because of the routing failure (I guess it also happens with other adapters - like Oracle, but I haven’t tested them). Again, think of what happens when the send port is the ESB Exception send port: your BizTalk box is going mad, but you have no idea since no exception can be written in the exception database! All of this can be tricky to diagnose, I can tell you that… Solution There is no real solution, only a work-around, but it won’t solve all of the problems and side effects. The idea is to create an orchestration which subscribes to all acknowledgments. That is to say: The message type of the incoming message will be XmlDocument The BTS.AckType property exists The logical receive port will use direct binding By doing so, all acknowledgments will be consumed by an instance of this orchestration, thus avoiding the routing failure. Here is an example of what this orchestration could look like: In order not to pollute the HAT and the DTA Db (after all, this orchestration is only meant to be a palliative to some faulty internal BizTalk mechanism, so there should be no trace of its execution), all tracking must be deactivated:

  • How to run VisualSVN Server on port 443 running IIS on same server?

    - by Metro Smurf
    Server 2008 R2 SP1 VisualSVN Server 2.1.6 The IIS server has about 10 sites. One of them uses https over port 443 with the following bindings: http x.x.x.39:80 site.com http x.x.x.39:80 www.site.com https x.x.x.39:443 VisualSVN Server Properties server name: svn.SomeSite.com server port: 443 Server Binding: x.x.x.40 No sites on IIS are listening to x.x.x.40. When starting up VisualSVN server, the following errors are thrown: make_sock: could not bind to address x.x.x.40:443 (OS 10013) An attempt was made to access a socket in a way forbidden by its access permissions. no listening sockets available, shutting down When I stop Site.com on IIS, then VisualSVN Server starts up without a problem. When I bind VisualSVN server to port 8443 and start Site.com, then VisualSVN Server starts without a problem. My goal is to be able to access the VisualSvn Server with a normal url, i.e., one that does't use a port number in the address: https://svn.site.com vs https://svn.site.com:8443 What needs to be configured to allow VisualSVN Server to run on port 443 with IIS running on the same server? Edit / Answer The answer provided by Ivan did point me in the right direction. For anyone else running into this, here is a bit more information. Even though my IIS had no bindings set to the IP address I am using for VisualSvn, IIS will still take the IP address hostage unless IIS is explicitly told which IP addresses to listen to. There is no GUI in Win Server 2k8 to configure the IP addresses for IIS to listen; by default, IIS listens to all IP addresses assigned to the server. The following will help configure IIS to only listen to the IP addresses you want: open a command prompt enter: netsh enter: http enter: show iplisten -- this will show a table of the IP addresses IIS is listening to. By default, the table will be empty (I guess this means IIS listens to all IP's) For each IP address IIS should listen to, enter: add iplisten ipaddress=x.x.x.x enter: show iplisten -- you should now see all the IP addresses added to the listening table. Exit and then reset IIS. Each of these commands can also be run directly, i.e., netsh http show iplisten If you need to delete an IP address from the listening table: open a command prompt enter: netsh enter: http enter: delete iplisten ipaddress=x.x.x.x Exit and then reset IIS.

  • Network is going down once per day

    Once per day the network on eth0 is going down and we need to do sudo ifdown eth0; sudo ifup eth0 to get the network up.

  • NIC interface names in /proc/interrupts

    - by Gallus
    When I look at /proc/interrupts: $ cat /proc/interrupts CPU0 CPU1 (...) 12: 4 0 IO-APIC-edge i8042 14: 145 65310875 IO-APIC-edge ide0 50: 0 0 IO-APIC-level uhci_hcd:usb5, Intel ICH7 58: 5388 7983508 IO-APIC-level libata 169: 812427252 1236572641 IO-APIC-level skge, eth1 217: 6 0 IO-APIC-level ehci_hcd:usb1, uhci_hcd:usb2 225: 0 0 IO-APIC-level uhci_hcd:usb3 233: 60 3108720778 IO-APIC-level uhci_hcd:usb4, skge I can see two skge and one eth1 entries. All of them are the network cards. Because of the general name "skge" (which is the name of the network driver of the card) I can't easily reocognize, which NIC occupies which interrupt. How to make linux use more descriptive names in the entries? Or: Is there any alternative way to obtain INT information instead of /proc/interrupt? My final goal is to manipulate smp_affinities of the NICs.

  • configure squid3 to set up a web proxy in ubuntu12.04

    - by Gnijuohz
    I am in a LAN and have to use a proxy given to access the web in a very limited way. I can't even use google, github.com or SE sites. However I can use ssh to log into a server, which I have root access so basically I can do anything I want with it. So I was thinking that maybe I could use that server as a proxy so I can visit sites through it. I tested it using ssh -vT [email protected] which gave a proper response. And In my computer I can't do this. Also I tried downloading something from the gun.org using wget, which can't be done in my computer too. And it succeeded on that server. I don't know if that's enough to say that this server have full access to the Internet. But I assumed so and I installed squid3 on it. After trying some while, I failed to get it working. I got this after I run squid3 -k parse 2012/07/06 21:45:18| Processing Configuration File: /etc/squid3/squid.conf (depth 0) 2012/07/06 21:45:18| Processing: acl manager proto cache_object 2012/07/06 21:45:18| Processing: acl localhost src 127.0.0.1/32 ::1 2012/07/06 21:45:18| Processing: acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 2012/07/06 21:45:18| Processing: acl localnet src 10.1.0.0/16 # RFC1918 possible internal network 2012/07/06 21:45:18| Processing: acl SSL_ports port 443 2012/07/06 21:45:18| Processing: acl Safe_ports port 80 # http 2012/07/06 21:45:18| Processing: acl Safe_ports port 21 # ftp 2012/07/06 21:45:18| Processing: acl Safe_ports port 443 # https 2012/07/06 21:45:18| Processing: acl Safe_ports port 70 # gopher 2012/07/06 21:45:18| Processing: acl Safe_ports port 210 # wais 2012/07/06 21:45:18| Processing: acl Safe_ports port 1025-65535 # unregistered ports 2012/07/06 21:45:18| Processing: acl Safe_ports port 280 # http-mgmt 2012/07/06 21:45:18| Processing: acl Safe_ports port 488 # gss-http 2012/07/06 21:45:18| Processing: acl Safe_ports port 591 # filemaker 2012/07/06 21:45:18| Processing: acl Safe_ports port 777 # multiling http 2012/07/06 21:45:18| Processing: acl CONNECT method CONNECT 2012/07/06 21:45:18| Processing: http_port 3128 transparent vhost vport 2012/07/06 21:45:18| Starting Authentication on port [::]:3128 2012/07/06 21:45:18| Disabling Authentication on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Disabling IPv6 on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Processing: cache_mem 1000 MB 2012/07/06 21:45:18| Processing: cache_swap_low 90 2012/07/06 21:45:18| Processing: coredump_dir /var/spool/squid3 2012/07/06 21:45:18| Processing: refresh_pattern ^ftp: 1440 20% 10080 2012/07/06 21:45:18| Processing: refresh_pattern ^gopher: 1440 0% 1440 2012/07/06 21:45:18| Processing: refresh_pattern -i (/cgi-bin/|?) 0 0% 0 2012/07/06 21:45:18| Processing: refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880 2012/07/06 21:45:18| Processing: refresh_pattern . 0 20% 4320 2012/07/06 21:45:18| Processing: ipcache_high 95 2012/07/06 21:45:18| Processing: http_access allow all I deleted some allow and deny rules and added http_access allow all so that all the request would be allowed.

  • Squid Proxy: url_regex acl is not working?

    - by bharathi
    I am using squid proxy 3.1 in ubuntu machine. I want to allow only urls matching our pattern through our proxy server. I configured acl like below. Acl for dstdomain is working fine. If i access any url besides .zmedia.com , I got proxy connection refused. But the url_regex is not working. What i am trying here is. Allow only request from ".zmedia.com" domain and the request url should be in "/blog" context. # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 ::1 acl urlwhitelist url_regex -i ^http(s)://([a-zA-Z]+).zmedia.com/blog/.*$ acl allowdomain dstdomain .zmedia.com acl Safe_ports port 80 8080 8500 7272 # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl SSL_ports port 7272 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager http_access deny !allowdomain http_access allow urlwhitelist http_access allow CONNECT SSL_ports http_access deny CONNECT !SSL_ports # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localhost # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 http_port 3128 # We recommend you to use at least the following line. hierarchy_stoplist cgi-bin ? # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir /var/spool/squid append_domain .zmedia.com # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 Please correct me , If i did anything wrong?

  • Tomcat and IIS 7 both on different ip's and different ports

    - by n00b
    I have Tomcat and IIS 7 installed together on a Windows 2008 server. The machine has two IPs (134.133.1.1 and 134.133.2.2). I want Tomcat to handle 134.133.1.1, on port 80, and IIS to handle both 134.133.2.2, on port 80 AND 134.133.1.1, on port 443, but can't seem to get the last two together (I can get one or the other by themselves on IIS, along with the first IP address on Tomcat). I have configured Tomcat to successfully listen to ip 134.133.1.1, on port 80 with this configuration; <Connector port="80" protocol="HTTP/1.1" address="134.133.1.1" connectionTimeout="20000" redirectPort="8443" /> I also have a site configured in IIS bound to ip 134.133.1.1, on port 443 (SSL). When I turn on IIS, after Tomcat, I can reach both 134.133.1.1:80 (Tomcat) and 134.133.1.1:443 (IIS) successfully (as desired). The problem now comes when I want to introduce a new site via IIS, at the new ip address. In IIS I have setup a new site at IP 134.133.2.2, port 80. I can not start the site. The event log shows this error; Unable to bind to the underlying transport for [::]:80. The IP Listen-Only list may contain a reference to an interface which may not exist on this machine. The data field contains the error number. I think this is because IIS 7 tries to listen to port 80 on all IPs, and it cant because Tomcat is taking port 80 for 134.133.1.1. From reading, the resolution is to specify the IP address you want IIS to bind on port 80. The problem is, when I add 134.133.2.2 to the iplisten list, then I get a 404 when I try navigating to 134.133.1.1:443. I assume this is because IIS is no longer listening to ANY port on 134.133.1.1. How do I resolve this such that IIS will return both sites? EDIT: Per request my IIS binding for site A is 134.133.2.2 on port 80 (http) and 134.133.2.2 on port 443. For site B in IIS, the binding is 134.133.1.1 on port 443 (https). Note the IPs in this example are just for example purposes, but consistent with my setup.

  • LACP : Cisco ASA 5515 & Switch ProCurve 2920

    - by user979276
    I've two ASAs 5515 connected in failover Active/Stand by (on Gi0/5) My two ASAs are connected to two Switch ProCurve 2920 to have HA if something happens. So I plug something like that (don't pay attention to the arrows) : So one the ASA, I created a Port-Channel like that : interface GigabitEthernet0/0 nameif outside security-level 0 ip address 192.168.1.3 255.255.255.0 standby 192.168.1.4 ! interface GigabitEthernet0/1 speed 1000 duplex full channel-group 1 mode passive no nameif no security-level no ip address ! interface GigabitEthernet0/2 speed 1000 duplex full channel-group 1 mode passive no nameif no security-level no ip address ! interface Port-channel1.1 vlan 1 nameif inside security-level 100 ip address 192.168.8.1 255.255.255.0 standby 192.168.8.2 ! interface Port-channel1.10 vlan 10 nameif guest security-level 50 ip address 172.16.100.2 255.255.255.224 standby 172.16.100.3 ! interface Port-channel1.16 vlan 16 nameif dmz security-level 50 ip address 192.168.16.1 255.255.255.0 standby 192.168.16.2 On the switch, I created a trunk LACP capable with the port 1 and 2 on each switch, force the speed to 1000 and put the port un full duplex mode. BUT this is not working... I tried many things and I can't make it work. In this configuration, I can't ping anything between my ASA and my Switch (or any object connected). Here what I get on my ASA : Channel group 1 LACP port Admin Oper Port Port Port Flags State Priority Key Key Number State ----------------------------------------------------------------------------- Gi0/2 SP not-bndl 32768 0x1 0x1 0x3 0xc Gi0/1 FP not-bndl 32768 0x1 0x1 0x2 0x6 And on the Switchs : PORT LACP TRUNK PORT LACP LACP NUMB ENABLED GROUP STATUS PARTNER STATUS ----- ------- ----- ------ ------- ------ 1 Active trk1 Broken Yes Failure 2 Active trk1 Broken Yes Failure If I change the Cisco interface to LACP mode On, I can ping the switch from the ASA but nothing other objects conneted on the switch. If I look at the statut of LACP on the switch I see this : PORT LACP TRUNK PORT LACP LACP NUMB ENABLED GROUP STATUS PARTNER STATUS ----- ------- ----- ------ ------- ------ 1 Active trk1 Up No Success 2 Active trk1 Up No Success I don't have any clue on what's going on so If someone have any idea and help me on this, it would be great ! Feel free to ask me anything if you need any more information ! Thanks a lot !
