ssh hangs – very slow ssh on mac

Robin — Sun, 05 Jun 2011 06:14:05 +0000

Since a few days ssh was very slow, searching many hours brings me to my router and suddenly i saw the problem…
Telenet my Internet Providers nameservers are slowing down the whole thing…

after verbose i had (ssh -vvv):
debug2: channel 0: open confirm rwindow 0 rmax 32768
and then it hangs/freeze

So from now i use http://www.opendns.org and everything is working again!

after verbose i had (ssh -vvv):
debug2: channel 0: open confirm rwindow 0 rmax 32768

Macbook oh my battery…

Since about two years i’m using my Macbook Pro 17″ every day, nice notebook, but the battery, they told me has to go for more then 7 hours, so i was happy when i bought the machine i could use it for about 6 hours… The reason was fair, i’m using internet, so i used my macbook as i used a normal desktop… But ok 6 hours was really fair for working, since a few months the battery suddenly only works for about 2 hours, oh uh ouch, i really need at least 4 hours, so i started my way and searching for hours, and then i found the problem, iavd (iAntivirus) and HPShortcutManage those two processes where the problem, after killing those two my machine was up and running again on battery for about 5 hours, so maybe could the people who write these programs give a sollution?

Sinds een jaar of 2 gebruik ik dagelijks mijn Macbook Pro 17″, een leuke notebook, maar de batterij… Bij de aankoop heeft men me laten weten dat de machine voor meer dan 7 uren moest werken op batterij, leuk, mijn Macbook deed het max. 6 uren, toch was ik blij daar ik geen enkele andere notebook kende die het zo lang kon volhouden op batterij! Tot een paar maanden terug plots de batterij maar 2 uren meer wilde meegaan, zelf in de lokale Apple shop (GCAB) liet men mij ontvallen dat de batterij wel stuk zou zijn en ik deze moest vervangen. Maar goed, ik heb dus een batterij nodig die 4 uren meegaat, zo start ik mijn zoektocht doorheen de notebook, hier krijg ik de processen in het oog en daar staan er 2 tussen die bijna alle resources verbruiken. iavd (iAntivirus) en HPShortcutManage, na het stoppen van deze twee boosdoeners draait de machine dus weer vlot 5 uurtjes mee op zijn batterij… Wel erg dat men me in de winkel in Brugge een nieuwe batterij wilde aansmeren zonder meer!

Apple Macbook Pro Bluetooth issue

Robin — Tue, 06 Jul 2010 14:55:48 +0000

Sometimes the bluetooth device of my mac suddenly disappears and could not be used untill cold reboot!
The message i got on my dutch version of Mac OS is: Bluetooth apparaat niet beschikbaar
Steps to take to solve the issue:

Most of the time a hold down of powerbutton and restart will help, but if not:
1) Put your mac in sleep state and wake him again, sometimes it helps…
2) click on the apple icon and choose restart
3) if the steps from above does not work, unplug all devices and also the power, then choose shut down and restart without power and devices, in most cases the BT is back working!

Hope this will help you… Last solution is an SMC reset as described on apple’s supportsite.
