@kaznelson: Thanks! Fixed it, and tweaked my upload script to take care of it automatically, because apparently that wasn't an isolated incident .

Nice work everyone

[NiLuJe]

Follow the instructions on the Wiki page, the sources are, well, the sources ^^. As a random end-user, you don't really need them .

yes it is....

# GET IT RIGHT!!!!!!!
ping -c2 192.168.1.150
#
#TODO, find where I left that generalised command to test for wifi "on"ness... sigh
# and shove it in here before the ping (it's on a kindle somewhere)

That gives me a double ping heartbeat every 15 secs via cron.

Seems to sort out most of the fails.

Thought I would share.

@twobob: The OpenSSH client has a (couple of) keepalive feature (one of which is disabled by default) that *might* help. I came upon it for completely unrelated reasons (silly new cable modem/router), but it might help.

ServerAliveInterval 15

(The server can do the same thing in reverse, via ClientAliveInterval, cf. man ssh_config & man sshd_config).

Did I already mention how much I hate Helvetica? Naah, I'm sure I did, somewhere.

Anyways, the latest KUAL snapshot (>= 2.3.19) now sports user-configurable fonts (for the KDK-2 version [ie. Touch/PW]), and the default font has been switched to Futura Regular. (I wish we could have been using the actual same font as most of the UI, which is actually Futura DemiBold, but apparently Java is stupid, so, nope).

This is configurable through two new config keys: KUAL_font_family & KUAL_font_style (cf. the default config).

EDIT: It's fairly useless there, but 2.3.25 now handles this on KDK-1, too.

[NiLuJe]

I just applied the tweaks mentioned in #36 to the OpenSSH configs in the USBNetwork snapshots.

Keep in mind that OpenSSH is *NOT* the default SSHD used by the hack, but if you're experiencing spotty connection issues (over WiFi and/or on FW 2.x for example), you might want to check it out .

[NiLuJe]

I just updated the snapshots. I rewrote some helper code used in all my install scripts, so if something behaves badly, please alert me . I couldn't find anything wrong during testing, but I could have missed something .

Forgive me my ignorance, but do you guys suspect serious problems with jailbreaking 5.4.5 for PW2?

edit:
My bad - I did not re-read the updated Jailbreak thread with the current status.

In answer to your question: Yes

[NiLuJe]

@sebarkh: Check the JB thread, there's a whole section dedicated to 5.4.5 in it.

sebarkh: Unfortunately there isn't much hope.
The empire strikes back - first they disabled downgrading (sort of), then they closed the only known attack vector.
The dark side is on the verge of reconquering our devices.
We are in need of another Skywalker :-)

Can "LIFE" exist without the irrational challenges posed by Lab126?



What would we all do with our free hobby time without these opportunities?

[NiLuJe]

I just updated the snapshots.

Dropbear was updated to the freshly released 2014.64 version, and I had to battle some fairly weird issues with it... In the end, strace, git bisect and some good old elbow grease won the day, but I'd be glad for some more testing! So if you're using dropbear with those snapshots, and something weird happens, give me a shout! .

But the good news is that I was able to enable the same kind of keep alive feature than I did in OpenSSH, so, if you had some reliability issues (especially over WiFi and/or on legacy devices), that might help .
