Hi all, Windows 2000 Ruby 1.8.2 R7 VC++ 6.0 I noticed that if I try to call new_work_item and give the task a name that already exists, I get a segfault: C:\eclipse\workspace\win32-taskscheduler>ruby test.rb "0.1.0" test.rb:22:in `new_work_item'': NewWorkItem() function failed (Win32::TaskSchedul erError) from test.rb:22 test.rb:22: [BUG] Segmentation fault ruby

Can you please show code example, how to draw graph with some nodes and edges, but with weights. I only found here http://www.bioconductor.org/packages/release/bioc/vignettes/Rgraphviz/inst/doc/Rgraphviz.pdf- Using edge weights for labels, but...

Uploading CSV file into R
Hi, I'm trying to upload two CSV files into R, and I'm having some trouble. I've used the instructions I've found on the Web, but they haven't helped so far. I'm worried this could be because I'm using a Mac. The two data sets are here: http://data.un.org/Data.aspx?d=WDI&f=Indicator_Code%3aNY.GNP.PCAP.PP.CD http://data.un.org/Data.aspx?d=UNODC&f=tableCode%3a1

[OT] How to use audio files with SIPp
Hello, SIPp's PCAP play feature can replay pre-recorded audio stream towards destination (see [1]). Doc mentions tcpdump and Wireshark as tools to record such RTP streams without further details. Looking at SIPp 3.2 source archive, I found PCAP samples in a pcap/ directory. Sample pcap/g711a.pcap file includes RTP from 10.1.3.1:5000 to 10.1.6.18:2006 1. How can you "forge" IPs

Re: unable to dissect libvirt rpc packets using wireshark plugin
Thank you Michal. With your pcap, I could confirm that, libvirt dissector worked in my environment as well. Yes, it could be that, my pcap do not have libvirt rpc packets correctly though I would have expected. I am checking on it.

tcpdump loses lots of packets
Hi folks, I've got a Dell R320 running CentOS 7, and a 10G NIC. I'm running a DNS server on it, for testing. As part of my testing, I'm attempting to capture all the DNS queries arriving on the server, using tcpdump. However, tcpdump's performance is abysmal, and it loses lots of the packets. Here's the output when I stop the capture: # tcpdump -nn -i p1p1 -w

Re: unable to dissect libvirt rpc packets using wireshark plugin
Hi Michal, Thank you for your suggestion. My apologies that I took sometime to get back on further confirmation. Regrettably, my tshark is still unable to find libvirt payload inside packet capture, though it lists libvirt as a possible filter. # rpm -ql libvirt-wireshark-1.2.9.3-2.fc21.x86_64 /usr/lib64/wireshark/plugins/1.12.5/libvirt.so As I used wireshark 1.12.6 version, I

syslinux.efi pxeboot across multiple subnets
Hum... Some packets seems duplicated when captured from the server, but not when captured from the mirror port. So let's assume that's ok. I can't find anything in the capture of the non-modified version that would look suspicious. Anyway, syslinux.efi is supposed to be downloaded by the UEFI firmware itself. It succeed but keep restarting for no apparent reason. Maybe an early

linphone calls not missed due to cause not 487
Hello. Calls cancelled by caller during the dialing phase, are shown in Linphone as simply past calls, not missed ones.

Asterisk16 - PJSIP - Error 401 on outbound registration
Hi all, we face a strange behavior while connecting an Asterisk16 instance with PJSIP to 2 providers: we receive error 401 Unauthorized, both of them having Kamailio as front-end. With other providers -we don't know if they run kamailio- registration is just fine. One of the provider took a pcap and told us that expiration was set to 0 that's why they don't accept the
