My LAN is behind a Netgear router, which does NAT. On the CentOS server I have fail2ban running. This morning my router reported 3 different IPs attempting to send UDP packets to port 38950, Since each address is only seen 4-5 times, I presume that fail2ban took over after that. GRC reports that ports are stealthed (port 143 was open, but is now closed), but then: Unsolicited Packets:

I have the firewall turned on my CentOS 5 box, but GRC is reporting that 631 is closed instead of stealthed. If the firewall isn't configured to allow that, then why might that be happening? Miark

Hi. I think that I've got some prolems with my netgear router. When I try to play the stream on my own computer it works very well, with http://localhost:8000/stream.ogg Also, if replasing localhost with the ip adress of the computer it works. But when trying to access it from outside it doesn't work. I've opened up port 8000 and 8001 on my router. Any idea what can be wrong? Can I

I''ve installed this fine software on my home network and am very pleased with the ease of installation and especially the documentation. My firewall box masq''s a private net via dialup modem. Configuration is almost exactly as described in the two-interface example. My question regards the result of a "internet test scan" that I found via google search...when I run

Guys, After i got the port forwarding and everything else working as per my previous post, i ran a shields-up scan from grc.com on the firewall, i.e. a scan of the external interface. I m a little suprised at the results. On the firewall i have postfix running ( smtp port 26 ), openssh ( ssh port 22) and port forwarding of port 85 (on the firewall ) to an internal host. The Shields-Up scan

Hi David, .. I think I've got it :-) Please let me know if you see anything glaringly wrong with this: library(RCurl) zWebObj <- postForm("https://www.semantic-mediawiki.org/w/api.php", "action" = "ask", "query" = "[[Category:City]]|?Capital%20of|?Has%20area", "format" = "json" .opts = list(ssl.verifypeer =

Right. I'm trying to access a server within my organization which has a cert error that I cannot fix. The example link I provided was to a site on the web that does not have the cert error. From the linux shell I use the "-k" switch with cURL to ignore cert errors.. is there an equivalent in the R world? -Rich -----Original Message----- From: David Winsemius [mailto:dwinsemius

That said, I have two issues to ask for help with: 1) how to ignore cert errors with a fromJSON call And 2) why the json data from the example link doesn't convert to a data frame. As seen in the following example library("rjson") result <- fromJSON(file =

[non-tabular json data] -- ok.. so I think I need to figure out how to make it tabular. Thanks! [curl] -- I was hoping there was a cleaner way to do it.. using R to evoke cURL to get the data as text and then passing it into getJSON seems to be what I need to do. Do you by chance have an simple example of using RCurl to get a response ignoring cert errors? ty -Rich -----Original Message-----

I?ve been tinkering and discovered that the link I need to read json data from is ?https? and there is a certificate warning that I have to click through from a browser. That might be my issue. Is there any way in the json package to tell it to ignore self-signed cert errors in a url? -Rich From: Eric Berger [mailto:ericjberger at gmail.com] Sent: Tuesday, May 08, 2018 11:31 AM To: Evans,

Regarding the question: From the linux shell I use the "-k" switch with cURL to ignore cert errors.. is there an equivalent in the R world? I have (sometimes) had success by creating a .curlrc file and putting the necessary curl options in it. When R invokes curl, curl picks up the options. [my context was running install.packages( method='curl' ) pointing to a local

On http://grc.com/default.htm I've found some bad news on the above service. It's true that if your windows network expose shared resources AND it is connect to Internet it can be bombed by hacker's attacks ? If yes, how to prevent it thru Linux-Samba ?

Hello I am able to construct a url that points to some data online in the JSON format. See an example at [0]. I would like to work with this data as a dataframe in R. I know that there is a package for handling json data [1] but it assumes the data is in a local file but It is not clear to me how to request the data from the web in an R script and get the json data converted into a data frame
