I have installed and started Stanford CoreNLP on AWS using this
java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -timeout 15000
This works on localhost
wget --post-data 'The quick brown fox jumped over the lazy dog.' 'localhost:9000/?properties={"annotators":"tokenize,ssplit,pos","outputFormat":"json"}' -O -
But when i call from a different terminal, using the External IP instead of localhost, client keeps looping.
wget --post-data 'The quick brown fox jumped over the lazy dog.' '13.126.58.85:9000/?properties={"annotators":"tokenize,ssplit,pos","outputFormat":"json"}' -O -
This is the message in client as it keeps trying......
--2018-09-10 17:01:44-- http://13.126.58.85:9000/?properties=%7B%22annotators%22:%22tokenize,ssplit,pos%22,%22outputFormat%22:%22json%22%7D
Connecting to 13.126.58.85:9000...
Any idea what could be issue ?

I'm using WFPSampler to redirect all traffic to a specific interface by using command:
WFPSampler.exe -s PROXY -l FWPM_LAYER_ALE_BIND_REDIRECT_V4 -pla 10.0.2.15 -v -in
This works just fine, traffic from all of the processes is redirected as expected. The only problem is that it binds 127.0.0.1 to 10.0.2.15 as well and then some applications fail to connect.
For example, I've created simple Python HTTP server on 127.0.0.1:8000 and I can not access it over the browser using this address.
I know that on FWPM_LAYER_ALE_BIND_REDIRECT_V4 it is only possible to filter by local address, but I have somehow to filter by remote address at this point to avoid binding localhost to 10.0.2.15
You could redirect the outgoing traffic from 10.0.2.15 to 127.0.0.1 at the same time, with the command like:
WFPSampler.exe -s PROXY -l FWPM_LAYER_ALE_CONNECT_REDIRECT_V4 -ipra 10.0.2.15 -pra 127.0.0.1 -v -in
The comments of this answer has metioned it.
I am writing a shell script that will take back-ups. The problem is the argument should be cURL request and the parameter passed with URL should ignore a particular index. I read ES cat API document but was not able to figure out and the other answers give grep as the solution.
health status index
green open abcd
green open efgh
green open ijkl
green open mnop
green open qrst
Commands Executed is:
curl -X GET "http://hostname:port/_cat/indices/*,-efgh"
curl -s http://hostname:port/_cat/indices | grep -v "efgh"
I want to ignore efgh while rest of the indices should be printed. Help would be appreciated
Error: {"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"efgh","index_uuid":"na","index":"efgh"}],"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"efgh","index_uuid":"na","index":"efgh"},"status":404}
You can use the following syntax:
GET _cat/indices/*,-efgh
which means "include everything, but efgh"
In curl, it would give this:
curl -s -XGET 'hostname:post/_cat/indices/*,-efgh*'
GET /%2Bindex1,-index2/type1,type2/_search?q=programming
Look at :

I am trying to simulate network latency for all traffic to a certain ip/url. I tried using a proxy through Charles but the traffic is going through HTTP or SOCKS. I found some information online but it does not seem to work for me. Can anyone see what is wrong with my commands?
#enable pf
pfctl -E
#add a temporary extra ruleset (called "anchor") named "deeelay
(cat /etc/pf.conf && echo "dummynet-anchor \"deeelay\"" && echo "anchor
\"deeelay\"") | sudo pfctl -f -
#add a rule to the deeelay set to send any traffic to endpoint through new rule
echo "dummynet out proto tcp from any to myurl.com pipe 1" |
sudo pfctl -a deeelay -f -
#Add a rule to dummynet pipe 1 to delay every packet by 500ms
sudo dnctl pipe 1 config delay 500
I see this warning when I run the commands:
No ALTQ support in kernel
ALTQ related functions disabled
Is that the issue?
The problem was the proto parameter. The application is not using tcp, it is using another protocol. You can either supply all the protocols you want as a list like so:
proto { tcp udp icmp ipv6 tlsp smp }
Or you can just remove the proto parameter altogether and it will do all protocols.
I have started jboss EAP 6.4 server with following parameter:

Server starts successfully.
I am running command: snmpwalk -c public -v 2c 127.0.0.1:1610
It gives
Error in packet.
Reason: authorizationError (access denied to that object)
File: /home/sshekhar/.snmp/mibs/snmp.acl has 700 access set to it.
I am new to SNMP and all I am looking forward is to configure JBoss 6.4 to use SNMP for monitoring.
Also, there is no data written in file: /home/sshekhar/.snmp/mibs/snmp.acl
Also, I created a user using
net-snmp-create-v3-user -ro -A password -X password -a MD5 -x DES myUser
Now, when I am trying to run the command snmpwalk -c public -v3 -u myUser -a MD5 -x DES -X password -A password localhost:1610
it gives me error saying snmpwalk: Unknown user name
snmpwalk -v1 -c public localhost:1610 gives no result
snmpwalk -v1 -c groupv3 localhost:1610 gives End of MIB
Can anyone please help me in understanding what might be the error and what should be my next steps to debug/resolve the issue?
I'm afraid I don't have an exact answer for you, but I can give you a little context about the SNMP versions-
SNMPv1 and SNMPv2c only use community string for authentication
An example SNMPv1 walk is as follows (community string is "public):
snmpwalk -v1 -c public 192.168.1.1
And an example SNMPv2c walk:
snmpwalk -v2c -c public 192.168.1.1
SNMPv3 has quite configurable authentication, using up to:
Security name (aka username)
Security level (noAuthNoPriv, authNoPriv, noAuthPriv, authPriv)
Auth protocol (e.g. SHA, AES)
Auth key (string)
Privacy protocol (e.g. MD5, DES)
Privacy key (string)
(optional) Context name
(optional Engine ID
As you can see, it can be quite complex- the "security level" is a setting that sometimes needs to be specified, it defines how much of the SNMPv3 security model you're using- if you're using an auth protocol and key and a privacy protocol and key, you'll need to use authPriv; if you're using none of those, you'll need to use noAuthNoPriv (just the security name).
An example SNMPv3 walk is as follows:
snmpwalk -v3 -u some_username -a SHA -A 'some_auth_key' -l authPriv -x AES -X 'some_privacy_key' 192.168.1.1
Basically, I'd recommend trying to setup SNMPv1 or SNMPv2c until you can get everything working nicely- I can't speak for JBoss, but on most networking devices this is simply a matter of picking an SNMP version (e.g. v2c) and specifying the read only community string (e.g. "public").
When/if you get to configuring SNMPv3, you might just have to be flexible with some of the different settings I find (again, in the context of network devices) that you won't find one setting that'll work on lots of different vendors of devices, you'll have to try some different auth protocols, different privacy protocols etc.
Best of luck!
My problem is that when I add a printer using the Printers and Scanners UI printing works, when I add the same printer using lpadmin it doesn't.
To Add it through the UI I did the following:
From Printers and Scanners I selected the IP tab.
Address: 10.20.30.40, Protocol HP Jetdirect - Socket, Queue left blank, Name: TEST_01, Location "Top Floor", Use -> Select software -> HP LaserJet P3010 Series
After doing this, the Printer works as expected.
This is a (segment from a) script containing my lpadmin command that doesn't work
SUBNET=socket://10.20.30.
TEST_01=40
PPD_DIR=/Library/Printers/PPDs/Contents/Resources
TEST_01_PPD="hp LaserJet P3010 Series.gz"
lpadmin -E -p TEST_01 -v $SUBNET$TEST_01 -P "$PPD_DIR/$TEST_01_PPD" -D "TEST_01" -L "Top Floor"
The printer appears correctly in the UI but shows as paused.
I did find a message in system.log that may or may not be relevant - I was using Notes to test the printer:
Notes[502]: Failed to connect (_delegate) outlet from (com_hp_psdriver_19_11_0_PDEView) to (com_hp_psdriver_19_11_0_PDEAccountingController): missing setter or instance variable
Notes[2198]: Printing failed because PMSessionEndDocumentNoDialog() returned -30871.
The reason I want to use a script is that there are 20 printers to add on each of 30 new Macs. The actual script uses a series of arrays with lpadmin in a for loop. Everything I have read says it should work. What am I missing?
I think -E specified before the printer name enables encryption, whereas specified after it Enables the printer - effectively "unpausing" it. Madness- I know!
Mad Apple Documentation - see second sentence
I think you want:
lpadmin -p TEST_01 -v $SUBNET$TEST_01 -P "$PPD_DIR/$TEST_01_PPD" -D "TEST_01" -L "Top Floor" -E
I don't have a direct answer, but I can suggest an alternate approach: set up all 20 printers by hand on one computer, then copy the /etc/cups directory from that one to the other 29.
