Sirs, According to RFC 2705 (MGCP), these are the parameters that are used in the transactions: ReturnCode, Connection-parameters <-- DeleteConnection(CallId, EndpointId, ConnectionId, [Encapsulated NotificationRequest,] [Encapsulated

Sirs, I have a question about CreateConnection (CRCX) at MGCP. For example, I have the phone number "5220107" and want to make a call for it using MGCP through a media gateway. How can I proceed? I know the command I must send to the media gateway should be like this: CRCX <trans_id> <endpoint> MGCP 1.0 "C", "L", "M" and "X"

Hi, I''m trying to create a "runtime-generic" ActiveRecord class, It means I don''t need to know the table or database, before I create my program ruby-rails. So I don''t need to predefine my database in environment.yml file and pre-build classes inherited from ActiveRecord::Base. I write some code, it seems to work. However, I can''t disconnect my

In trying to get samba on solaris 10 to integrate in our AD, I installed the version from blastwave. The problem I have now is that smbd seems to hang when I start it with smbd -D. The log output with -d 10 is probably too long to post, but here is the last rows before the hang: [2007/05/15 13:05:15, 5] lib/charcnv.c:(81) Substituting charset '646' for LOCALE [2007/05/15 13:05:15, 5]

I have a container rootfs that I use to keep all work-related stuff. This container was originally created by lxd (which creates all containers for use with user namespacing), but now I decided to start using libvirt for container management since I already use it for virtual machines, which will spare me from dealing with multiple hypervisor technologies. I managed to create a working domain xml

Consider this code. This is R 3.4.2, but based on a quick look at the NEWS, this has not been fixed. tryCatch( readLines(tempfile(), warn = FALSE)[1], error = function(e) NA, warning = function(w) NA ) rm(list=ls(all.names = TRUE)) gc() showConnections(all = TRUE) If you run it, you'll get a connection you cannot close(), i.e. the last showConnections() call prints: ?

Gabor, You can grab the connection and destroy it via getConnection and then a standard close call. (it actually lists that it is "closed" already, but still in the set of existing connections. I can't speak to that difference). > tryCatch( + readLines(tempfile(), warn = FALSE)[1], + error = function(e) NA, + warning = function(w) NA + ) [1] NA >

This has nothing to do with on.exit. It is an iteraction between where the warning is signaled in 'file' and your _exiting_ warning handler. This combination has the same issue, tryCatch(file(tempfile(), "r"), warning = identity) showConnections(all = TRUE) as does options(warn=2) file(tempfile(), "r") showConnections(all = TRUE) I haven't looked at the

Thanks for tracking this down. Yeah, I should use suppressWarnings(), you are right. Although, readLines() might throw another warning, e.g. for incomplete last lines, and you don't necessarily want to suppress that. TBH I am not sure why that warning is given: ? con <- file(tempfile()) ? open(con) Error in open.connection(con) : cannot open the connection In addition: Warning message: In

Yeah, that's often a possible workaround, but since this connection was opened by readLines() internally, I don't necessarily know which one it is. E.g. I might open multiple

Dear Mailinglist-User currently we`re working with an IP-PBX, based on Asterisk, with SIP, H.323 and ISDN-Capabilities. SIP and ISDN works fine, but H.323 not. In our first test, we started to connect Asterisk to an Cisco IOS-Gatekeeper with the "chan_oh323" (version 0.6.5). We successfully tested in/egress calls without any problems. But when we started to connect our Asterisk

Hi, I am making multiple calls to gzfile() via read.table(), e.g. > x <- read.table( gzfile( "xxx.gz" ) ) After i do this many times (I haven't counted, but probably between 50 and 100 times) I get the error message: Error in open.connection(file, "r") : unable to open connection In addition: Warning message: cannot open compressed file 'xxx.gz' however, I

Hi all, I'm writing a function that read data from a binary file. I want to close all opened connections, but it failed: > showConnections() description class mode text isopen can read can write 3 "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes" "no" 4 "daten/t5_all.mea"

Hello; I am new to R and trying to read a line from socket connection at a time but at the end of script I am getting "closing unused connection" warning. I am not able to understand how to solve this. I want to read a line from socket and then use read.table/scan on that line but it looks like I am opening multiple connections instead of just one. I think I am doing something wrong or
