linux - How to ssh into another machine immediately after logging into a machine -


problem: location i'm working cannot ssh master node application, 10.30.30.1 hosted country. solve this, have jump box can ssh location 10.50.50.1

and after logging jump box, again run command ssh 10.30.30.1

is there way save me step of first logging jump box , ssh master node, because that's thing use jump box for.

can configure jump box directly run ssh command moment log in? there commands allow me login directly master via jump box in single command or putty / moba xterm configuration?

say first execute ssh server1, on server1, execute ssh server2. thing want when execute ssh server1 on local computer, can automatically login server2.

the way add script runs automatically when login server1. can adding code ssh server2 ~/.bashrc file (if using ubuntu. or in other os, file name similar ~/.bashxxx).

but after doing so, still need type password server2 every time login server1. if don't want type server2's password hand, can use password-free ssh connection server1 server2. see this page find out how.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
