    [$] Shrinking the kernel with link-time garbage collection

    One of the keys to fitting the Linux kernel into a small system is to remove any code that is not needed. The kernel's configuration system allows that to be done on a large scale, but it still results in the building of a kernel containing many smaller chunks of unused code and data. With a bit of work, though, the compiler and linker can be made to work together to garbage-collect much of that unused code and recover the wasted space for more important uses.

    Click below (subscribers only) for a detailed article from Nicolas Pitre on how to use link-time garbage collection to create a smaller kernel image.

    Goodbye, net neutrality—Ajit Pai’s FCC votes to allow blocking and throttling (Ars Technica)

    In a vote that was not any kind of surprise, the US Federal Communications Commission (FCC) voted to end the "net neutrality" rules that stop internet service providers (ISPs) and others from blocking or throttling certain kinds of traffic to try to force consumers and content providers to pay more for "fast lanes". Ars Technica covers the vote and the reaction to it, including the fact that the fight is not yet over: "Plenty of organizations might appeal, said consumer advocate Gigi Sohn, who was a top counselor to then-FCC Chairman Tom Wheeler when the commission imposed its rules. 'I think you'll see public interest groups, trade associations, and small and mid-sized tech companies filing the petitions for review,' Sohn told Ars. One or two 'big companies' could also challenge the repeal, she thinks. Lawsuit filers can challenge the repeal on numerous respects, she said. They can argue that the public record doesn't support the FCC's claim that broadband isn't a telecommunications service, that 'throwing away all protections for consumers and innovators for the first time since this issue has been debated is arbitrary and capricious,' and that the FCC cannot preempt state net neutrality laws, she said."

    Protecting code integrity with PGP

    Linux Foundation Director of IT infrastructure security, Konstantin Ryabitsev, has put together a lengthy guide to using Git and PGP to protect the integrity of source code. In a Google+ post, he called it "beta quality" and asked for help with corrections and fixes. "PGP incorporates a trust delegation mechanism known as the 'Web of Trust.' At its core, this is an attempt to replace the need for centralized Certification Authorities of the HTTPS/TLS world. Instead of various software makers dictating who should be your trusted certifying entity, PGP leaves this responsibility to each user. Unfortunately, very few people understand how the Web of Trust works, and even fewer bother to keep it going. It remains an important aspect of the OpenPGP specification, but recent versions of GnuPG (2.2 and above) have implemented an alternative mechanism called 'Trust on First Use' (TOFU). You can think of TOFU as 'the SSH-like approach to trust.' With SSH, the first time you connect to a remote system, its key fingerprint is recorded and remembered. If the key changes in the future, the SSH client will alert you and refuse to connect, forcing you to make a decision on whether you choose to trust the changed key or not. Similarly, the first time you import someone's PGP key, it is assumed to be trusted. If at any point in the future GnuPG comes across another key with the same identity, both the previously imported key and the new key will be marked as invalid and you will need to manually figure out which one to keep. In this guide, we will be using the TOFU trust model."

    [$] MAP_FIXED_SAFE

    The MAP_FIXED option to the mmap() system call allows a process to specify that a mapping should be placed at a given virtual address if at all possible. It turns out, though, that "if at all possible" can involve a bit more collateral damage than some would like, and can even lead to exploitable vulnerabilities. A new, safer option is in the works but, as is often the case, it has run into a bit of non-technical difficulty.

    [$] Process tagging with ptags

    For various reasons related to accounting and security, there is recurring interest in having the kernel identify the container that holds any given process. Attempts to implement that functionality tend to run into the same roadblock, though: the kernel has no concept of what a "container" is, and there is seemingly little desire to change that state of affairs. A solution to this problem may exist in the form of a neglected patch called "ptags", which enables the attachment of arbitrary tags to processes.

    [$] Federation in social networks

    Social networking is often approached by the free-software community with a certain amount of suspicion—rightly so, since commercial social networks almost always generate revenue by exploiting user data in one way or another. While attempts at a free-software approach to social networking have so far not met widespread success, the new ActivityPub federation protocol and its implementation in the free-software microblogging system Mastodon are gaining popularity and already show some of the advantages of a community-driven approach.

    Nottingham: Internet protocols are changing

    Worth a read: this APNIC blog entry from Mark Nottingham on the near-term evolution of various Internet protocols. "The newest change on the horizon is DOH — DNS over HTTP. A significant amount of research has shown that networks commonly use DNS as a means of imposing policy (whether on behalf of the network operator or a greater authority). Circumventing this kind of control with encryption has been discussed for a while, but it has a disadvantage (at least from some standpoints) — it is possible to discriminate it from other traffic; for example, by using its port number to block access. DOH addresses that by piggybacking DNS traffic onto an existing HTTP connection, thereby removing any discriminators."

    [$] Toward better CPU load estimation

    "Load tracking" refers to the kernel's attempts to track how much load each running process will put on the system's CPUs. Good load tracking can yield reasonable predictions about the near-future demands on the system; those, in turn, can be used to optimize the placement of processes and the selection of CPU-frequency parameters. Obviously, poor load tracking will lead to less-than-optimal results. While achieving perfection in load tracking seems unlikely for now, it appears that it is possible to to do better than current kernels do. The utilization estimation patch set from Patrick Bellasi is the latest in a series of efforts to make the scheduler's load tracking work well with a wider variety of workloads.

    Υπηρεσίες Δικτύου • Cannot access Ruckus R310 web interface

    Hi there,

    I have three R310 Unleashed access points in a mesh network. I want to broadcast two SSIDs -- one for departmental traffic and one for guests, each with its own VLAN. I originally had the ports set up as access ports and my primary SSID was working and I could configure my system through the web interface. To achieve my goal of two SSIDs on separate VLANs I configured the ports on my Cisco C3750 routers as 802.1q trunk ports and allowed VLANs 1,30 and 60 and designated 1 as the Native VLAN. 30 is for the department SSID and 60 is for Guests. I set the Access IP on the departmental SSID to 30, and have not yet configured the Guest VLAN. I was tested my departmental network and got good connections -- all APs were broadcasting properly Here's the rub -- when I went back to my desk I could no longer access my AP through the web interface. I also cannot ping it. When I set the port on the switch back to static access, I can ping the AP and can again access it through the web interface from VLAN 1, but the AP does not show as connected to the Internet. What could cause this?

    Thanks

    Υπηρεσίες Δικτύου • Help with replacing Isp router/modem

    Hi all,

    My Isp gave me a router/modem which is not that reliable and I can't really use solely my aftermarket one because it has to have VOIP (or the phones at home won't work at all which I don't really use but it's nice to have) and something called hybrid connection (which basically accepts a Sim card inside and combines 4g network with dsl*).

    Possible solution:
    What I though of doing Is use the Isp router as a modem and route the internet through my router and let it handle the wifi and ethernet connections.
    Is that a good idea?

    I Would really prefer an alternative though which does not include my isp router/modem.

    Are there any aftermarket routers/modems that accept Sim cards and have voip?

    Is there any other modem router combinations I could try?
    Any help will be gladly accepted.

    Thanks!

    Στην συγκεκριμένη περίπτωση είναι δύσκολο να εντοπιστούν οι πηγές φαντασμάτων γιατί είναι πολλές. Για παράδειγμα ο ipduh #20305 με αρκετούς RouterOS <6.38.x θεωρεί πως ο κόμβος nvak είναι μια χαρά up & running:

    Code:

    5   20305 10636 11607 2315 17615
    5   20305 10636 11607 2315 810

    Μετά από ένα σχεδόν χρόνο λειτουργίας και ανάπτυξης της SupperQuagga, ο εντοπισμός προβλημάτων στο BGP είναι ιδιαίτερα απλός και εύκολος. Ειδικά για τα φαντάσματα, υπάρχει η δυνατότητα έγκυρου εντοπισμού τους και τελευταία βρέθηκε μέθοδος να ακυρώνονται από το BGP χωρίς πρόσβαση στους προβληματικούς router που τα προκαλούν.

    Η διαδικασία είναι απλή:

    Code:

    Αφού εντοπιστούν τα prefix φαντάσματα, τα AS που τα συνοδεύουν δεν μας ενδιαφέρουν ούτε απασχολούν, μπορούν να ανακοινωθούν για 3-4 λεπτά από κάποιον κόμβο που δεν έχει γείτονες με προβληματικά RouterOS και μετά να αποσυρθούν.

    Όσες φορές δοκίμασα την παραπάνω διαδικασία σε φαντάσματα που για καιρό (κακώς) βρισκόντουσαν στο BGP, αυτά, μετά την παραπάνω διαδικασία, αποσύρθηκαν αμέσως.

    σήμερα με τον πρωινό καφέ, παρατήρησα ένα AS ghost που δεν είχε prefix

    Code:

    (44)    1910 3936+ 22486 3725* 2379 2315 810 3252 3665 3016* 18523# 11607 8345# 18524# 20875# 8580 2711# 3507# 14735 10814 17633 16480 8449 13133 11244 12752* 20776 2581* 10636 20305# 19174* 3670* 17751* 5078 4097 2841* 1124 10218 7597 14609 10130* 12629 19695 3280#* 

    LMGG candidate: #10130 Gounara 10.2.159.1 v5.21 43.666 days (since Fri Jul 28 12:20:04 2017)

    αν οι γειτονικοί κόμβοι του #10130 Gounara εφάρμοζαν τουλάχιστον τα προτεινόμενα BGP φίλτρα του AWMN που κόβουν path >26, δεν θα κυκλοφορούσε ελεύθερο το συγκεκριμένο φάντασμα.

    άκυρη η μέχρι τώρα θεωρία πως ghost μπορεί να μείνει μόνο αποσυρμένο prefix με όποιο AS το συνόδευε τελευταία

    AWMN Γενικα • BGP /24 anycast

    Χθες παρατηρήθηκαν στην SupperQuagga anycast /24 ανακοινώσεις. Για παράδειγμα για το prefix: 10.55.55.0/24

    Code:

    4     10721 6233 3016 263
    4     18747 6233 3016 263
    5     913 410 18523 3016 263
    5     3200 410 18523 3016 263
    5     3298 9632 9627 6840 6818
    5     6610 10721 6233 3016 263
    5     7736 13133 1 21392 6818
    5     8345 11607 18523 3016 263
    5     11087 410 18523 3016 263
    5     13101 9474 9627 6840 6818
    5     15199 18747 6233 3016 263
    5     17295 9632 9627 6840 6818
    5     17983 10721 6233 3016 263
    5     21498 410 18523 3016 263

    είναι πολύ πιθανό το φαινόμενο να οφείλεται σε κακή ρύθμιση μια και αν υλοποιηθεί τότε οι εμπλεκόμενοι κόμβοι στο /24 anycast, στην συγκεκριμένη περίπτωση #263 & #6818 δεν θα είναι προσβάσιμοι ταυτόχρονα από όλο το δίκτυο αλλά ο κάθε ένας από αυτούς θα είναι προσβάσιμος μόνο στους πιο κοντινούς του σε αυτόν κόμβους.

    Οι anycast κόμβοι είναι πολύ δύσκολο να ανιχθευθούν από κανονικούς κόμβους που τρέχουν BGP. Η SupperQuagga με το multi-peering από διαφορετικά γεωγραφικά σημεία του δικτύου, δίνει την δυνατότητα πληρέστερης και εγκυρότερης πληροφορίας για την συνολική εικόνα του δικτύου.

    Δημιουργήθηκε ένα νέο πεδίο στα εργαλεία της SupperQuagga bgp hidden-anycast που αποτυπώνει αυτούς τους /24 anycast κόμβους.

    Το συγκεκριμένο πρόβλημα πιθανά να δημιουργείται από διασύνδεση των δυο κόμβων με κάποιο tunnel ή IGP το οποίο μεταφέρεται τοπικά στο iBGP του κάθε κόμβου και από εκεί στο eBGP.

    AWMN Γενικα • Re: BGP Quiz

    Σήμερα αποφάσισα να ανακοινώσω από ozonet #3298 ότι ghost prefix κυκλοφορεί στο δίκτυο, ώστε να δω τα αποτελέσματα με το που αποσύρω τις σχετικές ανακοινώσεις.

    θα μείνουν τα φαντάσματα με AS το #3298; θα επιστρέψουν στην παλιά τους κατάσταση; ή θα αποσυρθούν τελείως;

    Edit: Τελικά αποσύρθηκαν με τις παρακάτω εξαιρέσεις:

    ενώ ανακοινώνω κανονικά και έγκυρα αυτά τα prefix, ο router του #4084 chrismarine που είναι και SupperNode στην SPQ συνεχίζει να ανακοινώνει την παλιά διαδρομή φάντασμα.

    αξιοσημείωτο είναι πως ο SupperNode #4084 τρέχει v6.38.5 ενώ οι #14735 & #22486 v6.40.3

    επίσης ο SupperNode #2272 Diasnet v6.40.3 δεν έχει το συγκεκριμένο φάντασμα

    Ανακοινώσεις • Re: Μεταφορά Website

    Μέχρι πρότινος ο server ετρεχε windows (10.140.14.67) και ενα debian (10.140.14.70, .73) σε virtualmachine, οπότε οι υπηρεσίες ηταν μοιρασμένες.

    Έχω αρχίσει να τις μεταφέρω όλες στο 14.73 για να έχουμε ένα VM που να μπορεί να τρέξει και αλλού σε περίπτωση που πέσει το δικο μου.

    Services που έτρεχαν στο 14.67 και μεταφέρθηκαν στο 14.73:
    -IRC
    -DNS
    -DNS bot
    -Proxy


    Services που τρέχουν στον 14.73: websites, hotspot, moufospot dns, ntp

    Όσοι χρησιμοποιείτε το 14.67 γινεστε redirect στο 14.73, αλλά καλό θα ήταν να αλλάξετε τις ρυθμίσεις σας (κυρίως τον DNS).

    Κάποια services όπως DC hub, DC Link, Dude τρέχουν μόνο σε windows οπότε θα τα καταργηθούν σε περίπτωση που σβήσει ο server. Ίσως βέβαια να υπάρχει κάπιο linux DC server και Dude που να τρέχει σε mikrotik.
