linux - Siege aborted due to excessive socket failure -


i have encountered problem whilst trying run off following cmd siege on mac os x 10.8.3.

siege -d1 -c 20 -t2m -i -f -r10 urls.txt

the output siege following:

** siege 2.74 ** preparing 20 concurrent users battle. server under siege... done. siege aborted due excessive socket failure; can change failure threshold in $home/.siegerc  transactions:                  0 hits availability:               0.00 % elapsed time:              27.04 secs data transferred:           0.00 mb response time:              0.00 secs transaction rate:           0.00 trans/sec throughput:             0.00 mb/sec concurrency:                0.00 successful transactions:           0 failed transactions:            1043 longest transaction:            0.00 shortest transaction:           0.00  file: /usr/local/var/siege.log can disable annoying message editing .siegerc file in home directory; change directive 'show-logfile' false.

the problem may run out of ephemeral ports. remedy that, either expand number of ports use, or reduce duration ports stay in time_wait, or both.

expand usable ports:

check current setting:

$ sudo sysctl net.inet.ip.portrange.hifirst

net.inet.ip.portrange.hifirst: 49152

set lower expand window:

$ sudo sysctl -w net.inet.ip.portrange.hifirst=32768

net.inet.ip.portrange.hifirst: 49152 -> 32768

(hilast should @ max, 65536)

reduce maximum segment lifetime

$ sudo sysctl -w net.inet.tcp.msl=1000

net.inet.tcp.msl: 15000 -> 1000

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
