similar to: Netbios port 139

I was wondering if anyone here has or knows how to implement ttysnoop w/ssh ?

Are there any known vulnerabilities in portmap (redhat''s portmap-4.0-7b)? I''ve been receiving a lot of attempts to access the portmap port on some linuxppc machines I administer by various machines which clearly have no business with mine, and I wonder if this is an attempt to break in to my machines. I''ve searched some archives, but I haven''t yet found any

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 =

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

I''ve kept this one on the back burner for a while, waiting for it to mature before attempting to use it, and now having seen OpenBSD ship with IPSec I''m getting a bit impatient =). What is the status of IPSec for Linux (and more specifically RedHat)? By this I mean I just did some www browsing/etc and found about a half dozen different implimentations, ranging from NRL, to a

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

Hi, I was wondering how a linux box configured as a firewall stacked up against some of the commercial products like checkpoint-1 and gauntlet. Can someone direct me to a good book or online doc that compares linux to some other firewall methods? Mind you, I''m not talking about a firewall in the classical sense, ie ip forwarding turned off and used as a proxy, but the typical Linux box

Michel, One approach that hasn't been suggested is to block access to the netbios nameservice port on the samba host with a firewalling rule. That way the other computers on the subnet can't register themselves with nmbd. Suppose that your internal network is all within the 192.168.15.0/24 network. Each Windows workstation will automatically announce itself with a udp packet broadcast

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

Hello, I just made available a beta version of a port scan detector that I''ve been working on. The program, called Abacus Sentry, is a port scan/probe detector that offers what I think are a number of unique and useful features: - Runs on TCP or UDP sockets. Configurable by the user to bind to multiples of sockets for increased detection coverage. - Adjustable scan detection value with

I''m in the process of locking down as much of my systems here as possible as to available ports. I am down to only a handful but am not sure how much of a security risk they pose and was wondering if anyone here might be able to comment, or suggest secure versions to run: 21/FTP (WU-ftpd v2.4.2 BETA 14) 22/SSH (1.22) 23/TELNET (Netkit 0.09) 25/SMTP (Sendmail

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
