windows - Dealing with corporate firewall adding self-signed certificates -


i work in small group inside of large company.

all network traffic goes through company's firewall, think acts man-in-the-middle when traffic comes in.

one example see when using curl

c:\>curl https://www.google.com curl: (60) ssl certificate problem: self signed certificate in certificate chain

so check certificate chain with:

c:\>openssl s_client -connect google.com:443

and (with details removed)

certificate chain  0 s:/c=us/st=california/l=mountain view/o=google inc/cn=*.google.com    i:/c=us/my company's intermediate ca  1 s:/c=us/my company's intermediate ca    i:/c=us/my company's root ca  2 s:/c=us/my company's root ca    i:/c=us/my company's root ca

this provides challenge using package managers npm or composer because https fails due self-signed certificate error, or not being able verify certificate

i can npm work setting config values ca="" , strict-ssl=false, that's insecure practice.

i'd our development team have access package managers, npm , composer

given i'm not going able change how firewall works, there changes can make on local machine (windows 7) or vm (windows server 2008 r2) allow our development team utilize these package managers securely.

thanks!!

i asked around @ company , talked right person said:

all our internet traffic passes through company. company intercepts https traffic, replaces certificate , adds own certificate. can decrypt , analyze encrypted traffic (essentially man in middle attack).
company root certificate must trusted avoid warnings , errors.

i got link download proper pem key.

using key able set proper config options various package managers.

npm

npm config set cafile c:\\path\\to\\cert.pem npm config set strict-ssl true

(needed double slashes in windows)

composer

had set values in php.ini composer work.

openssl.cafile = c:\path\to\cert.pem curl.cainfo = c:\path\to\cert.pem

for other programs threw certificate error (not verified, self-signed, etc), ended finding sort of config setting point pem file , work.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
