New router, worse router

Our internet overlord TeleCable has decided to upgrade the hardware they had installed at home (the old Motorola SURFboard SB5101E) to something new, supporting DOCSIS 3.0, so they can happily say all their customers enjoy 100 MBps download rates. Not checked this fact yet, though.

The hardware of choice (I wonder who choose it) is a Cisco EPC3925, which comes also with Wi-Fi, so I decided to shut down my Linksys WRT54GL, for saving some electricity and enjoy the faster Wi-Fi (N in the Cisco vs G in the Linksys).

Unfortunately the EPC3925 doesn't like machines with static IP addresses on the network and was unable to route between two of them using the wired ports. Strangely both machines were reachable when accessed from a third machine connected to the wireless network with static address too (!).

After struggling for a whole afternoon with it (even reformatted the SD card of one of the machines thinking it could be the problem) I gave up using static addresses and just solved it the other way around:

  • Reconfigure the whole set of machines with static addresses to use DHCP instead

  • Watch the machines to pop up in the router's client list as they connected to the network and write down their MAC address

  • Configure the router DHCP server to give a determined address to each machine MAC

This way they still have a fixed address but now the router is capable to route traffic among them. While I was at it I decided to collect the MACs of the devices which had no fixed address (TV, Wii, Smartphone) and give them an address, so now with a simple ping I can now check if they're on or off :-) (before I had to nmap the whole /24 segment to be able to identify the machines).

Anyway, despite it works mostly OK now I'm still not liking it much. Clearly it's a substandard device (each time you expand the DHCP address range every other DHCP configuration is lost!), and who knows what other surprises it hides. For now it has entered the while it works, don't touch it category, but I don't expect it to last as longer as the Linksys.

MTFAQ: /ˈɛmtiːfak/, n.

  1. More Than FAQ

  2. When a developer has become so tired of a FAQ that decides to doc it or even change the code to remove the FAQ from the list, it's said that FAQ has become an MTFAQ.

Downgrading to stable

This weekend I had to downgrade my home desktop to stable thanks to a strange Xorg bug which I've been unable to identify among the current ones. Both testing and sid versions seem affected and all you can see after booting is this:

The system works fine otherwise and can be accessed via ssh, but restarting kdm doesn't help to fix it, it just changes the pattern. Anyway, as explaining a toddler he cannot watch his favourite youtube cartoons because suddenly the computer screen has become an abstract art work is not easy I quickly decided to downgrade.

Downgrading went fine, using APT pinning to fix stable and apt-get update/upgrade/dist-upgrade after that, but today I noticed libreoffice stopped working with this message:

Warning: failed to launch javaldx - java may not function correctly
/usr/lib/libreoffice/program/soffice.bin: error while loading shared libraries: cannot open shared object file: No such file or directory

All I found related to that is a post on forums, which didn't help much (neither the original poster nor me). But just found the library was not missing, it was installed:

# locate

But that was not part of any ldconfig conf file, hence the fix was easy:

# echo '/usr/lib/ure/lib' > /etc/
# ldconfig

And presto! libreoffice is working again :-)

Bye bye DebConf15

Yep, I had planned to go, but given the last mail from registration seems there's a overwhelming number of sponsorship requests, so I've dediced to withdraw my request. There's lots of people doing much more important things for Debian than me which deserve that help. Having to complete my MSc project does also help to take this decision, of course.

I guess the Debian MIA meeting will have to wait for next planetary alignment ;-) well, not really, any other member of the team can set up it, hint! hint!

See you in DebConf17 or a nearby local event!
