Re: [hopefully on topic] is SSH secure in default configuration?
The algorithm itself is the least of your worries. In modern cryptography, key management is the preferred target. With regards to ssh, this means the key negotiation phase of the protocol handshake. Using your own keys of reasonable size, and managing them properly, is your best bet for reasonable security, along with configuring sshd not to fallback to SSHv1, as Eliyahu wrote. For a wider perspective of the latest NSA revelations, I recommend this article by Bruce Schneier: http://www.theguardian.com/world/2013/sep/05/nsa-how-to-remain-secure-surveillance Rony On Sun, Sep 8, 2013 at 3:19 PM, Oleg Goldshmidt p...@goldshmidt.org wrote: Hi, I am not hopeful to secure much of anything against the likes of NSA or GCHQ. However, my curiousity woke up when the latest NYT/Guardian/ProPublica pieces about NSA/GCHQ/friends compromising much of Internet encryption were accompanied by graphics like http://www.nytimes.com/interactive/2013/09/05/us/unlocking-private-communications.html Now, NYT is hardly a technical authority, but I assume they have technically competent sources and advisers. The above page lists Cisco, Microsoft (I wonder if they were the ones who outed Skype - chuckle), and EFF as sources. I shrug at HTTPS/SSl/TLS/VPN/Skype,IM - nothing surprises there. The only part that is somewhat surprising (and particularly relevant to Linux-IL) is SSH. Why is SSH (on Linux) included and is the inclusion justified? A glance at man 5 ssh_config (or man 5 sshd_config) reveals the Ciphers section and the default preference list for v2 ciphers, with AES-128 in the leading position. Can any security/cryptography guru here (Or? Aviram? Noam? anyone?) confirm or deny that AES-128 may be suspect? AES-256 still seems to be regarded as NSA-safe (but not RC4? http://www.theregister.co.uk/2013/09/06/nsa_cryptobreaking_bullrun_analysis/). Is it prudent to reconfigure ssh/sshd to prefer AES-256? Can anyone comment on performance impact of using AES-256 vs. AES-128 for the usual scenarios? I am not sure I quite understand the implications of AES-128 and AES-256 both being NSA-approved as Type-1/Suite-B algos. I'd hope that NSA assume that anything they can break others can break, too, so Type 1 product being defined as endorsed by the NSA for securing classified and sensitive U.S. Government information, when appropriately keyed hopefully means NSA cannot break it. However, there is also Type-1/Suite-A... Suite A being seemingly regarded as even more secure than Suite B (is it?) goes against the common cryptographic wisdom that says disclosed algos deserve more trust. Is it an indication that (at least) AES-128 may be somewhat vulnerable? Or is is only because AES was not historically NSA-sourced that it is in Suite B and not in Suite A? http://en.wikipedia.org/wiki/Type_1_product http://en.wikipedia.org/wiki/NSA_Suite_B_Cryptography http://en.wikipedia.org/wiki/NSA_Suite_A_Cryptography Back to NYT graphics: Another, more mundane possibility is that NSA's partial success against SSH (and/or OpenSSH implementation) means that SSHv1 and DES (and maybe the default triple-DES???) are vulnerable. That would not be a big surprise (at least the DES part). I am not changing the default SSHv2 Ciphers configuration unless someone I trust says AES-128 is suspect. And maybe not even then...

Recently I've learned that suspend is quite reliable and of course much faster. I suspend either automatically on lid closure, or manually, and come out of suspend automatically when I open the lid. Occasionally, coming out of suspend fails. The power indicator light is on, as well as bluetooth and wifi. Wifi is even blinking occasionally, but I don't know what this means. The disc activity light is off. The only keys that are recognized are the NmLk and the little lamp that lights up the keyboard. I suspect these are handled by a microcontroller running the keyboard and not the main processor. Every other key and key combination I can think of is ignored, e.g. Ctrl Alt F1 etc. to get a console login. I have tried closing and reopening the lid, applying and removing external power, and pressing every single key, along with every combination of Shift Ctrl and Alt, as well as the blue Fn button. Other than the numlock and keyboard lamp, nothing has any effect. I have tried both hibernating automatically on lid closure, and hibernating manually prior to lid closure. The problem seems worse when I hibernate automatically, but this is not a terribly scientific conclusion. I realize now that I may have been seeing the same problem when coming out of hibernation. I recognize that the problem may not be been caused by a problem starting up, but rather, due to some error while hibernating or suspending. What can I do to debug this?

One can get core i3 for around $500 So here are my questions: 1. Does anyone know if Win7 includes a virtualization program that would allow me to run Linux under it? How efficient is it - will I be able to put it on full screen, forget I am running Windows, and use my preferred environment? 2. Any recommendations for something that is fully compatible with Linux, in case I get an alternative and can get rid of the windows part? 3. Any other advice? Thanks!

RE: What to do with a constant flow of attempts to login to my compuet?
Hi Gabor, Moving sshd off port 22 to any non-standard port worked fine for me. Most attacks are too lazy to do a full portscan, so if they don't find the default port open, they just move to the next host. Of course, this is assuming that the attack chose you at random. If it's a targeted attack, this won't help very much...

RE: [OT] Power over radio is it a true thing or just a myth ?
ubergeek-mode Actually, the speed of light *in a vacuum* is the universal constant, invariant regardless of the observer's frame of reference. 'C' is so defined - the speed of light in vacuum. This is now understood to be such a basic constant that in 1983, the meter was defined in terms of the speed of light: The definition states that the meter is the length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a second. http://www.mel.nist.gov/div821/museum/timeline.htm Note that when a particle exceed the speed of light *in a given medium*, it gives off cerenkov radiation, analogous to a sonic boom.

Gilad Ben-Yossef wrote: Despite popular belief, the speed of light is only fixed in vacuum and scientists long acknowledged the fact that light may travels in different and lesser speeds when going through different materials, such as air, or water. Again, not precisely accurate. While light will, indeed, travel slower through any material denser than vacuum, this is not what the term speed of light refers to. To the best of my knowledge, speed of light refers to a basic property of the universe (how fast will any change of any field propagate), and that is the property that goes into the time warping formulas (the famous c in Lorentz transformation). Just because light travels through glass at 30% less speed does not mean you have to aim 30% lower if you want to freeze time (unless, and this is something I'm not 100% clear about, YOU are traveling through glass as well). 88 miles per hour, it would seem, is the speed of light as it travels through Hollywood movies. At least that one seems pretty accurate. This also explains why pretty much anything looks different when viewed through the filters of a Holywood movie.

Configuring fallback IP address in dhclient.conf
Hi, I've an appliance (running Debian Etch) that needs to be able to run in an environment that might or might not have a dhcp server handy. I've made the following changes to dhclient.conf, and got surprising results: 1. The changes: timeout 10 ; lease { interface eth0; fixed-address 192.168.0.58; option subnet-mask 255.255.255.0; renew 2 2037/1/12 00:00:01; rebind 2 2037/1/12 00:00:01; expire 2 2037/1/12 00:00:01; } 2.

RE: Configuring fallback IP address in dhclient.conf [solved]
Thanks, Gilad. While not quite the problem, it was enough to point me in the right direction. For those interested: The ping was called in /sbin/dhclient-script, called by dhclient as part of the handling of the dhcp response. The exact invokation is if ping -q -c 1 $first_router; then Obviously, $first_router wasn't set, resulting in the usage error I saw. Fix? Added option routers aaa.bb.ccc.ddd to the dhclient.conf lease {} stanza, so it's now: lease { interface eth0; fixed-address 192.168.0.58; option subnet-mask 255.255.255.0; option routers 192.168.0.58; renew 2 2037/1/12 00:00:01; rebind 2 2037/1/12 00:00:01; expire 2 2037/1/12 00:00:01; } Cheers, Rony _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gilad Ben-Yossef Sent: Monday, August 04, 2008 2:39 PM To: [EMAIL PROTECTED] Cc: linux-il@cs.huji.ac.il Subject: Re: Configuring fallback IP address in dhclient.conf ronys wrote: Listening on LPF/eth0/00:90:fb:15:e0:00 Sending on LPF/eth0/00:90:fb:15:e0:00 Sending on Socket/fallback DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 7 DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4 No DHCPOFFERS received.

Since having two stations use the same IP address is a very hard situation to debug, as packets will randomly find their way to either of the stations, dhclient does a very sensible thing and before using a stored address in the case no DHCP server answers, it makes an attempt to ping the address it is going to use in an effort to try and detect if someone is already using it. In your case this backfires as it seems the 'ping' command format it is trying to use is somehow not compatible with your 'ping' command.

RE: Dropbear SSH
Hi Oleg, No experience with Dropbear, but I've used LibTomCrypt in a couple of projects, and it rocks. You can configure it to the level of paranoia you're comfortable with, e.g., scrubbing memory that contains keying material, etc. - the typical security/performance and time/space tradeoffs. Of course, having a solid crypto library is a necessary but *not* sufficient condition for a secure application, as it's trivial to misuse crypto in a way that leaves you totally insecure. HTH, Rony -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Oleg Goldshmidt Sent: Thursday, July 17, 2008 1:42 PM To: Linux-IL Subject: Dropbear SSH Hi everybody, Does anyone have experience with DropBear SSH server/client (http://matt.ucc.asn.au/dropbear/dropbear.html)? The context is an embedded product with AMCC PPC460, Linux (say, 2.6.25 or later), and busybox (1.10 or later) as the base, being defined/designed now. The target audience is top tier customers, such as governments, Fortune-whatever companies, major financial institutions, etc. SSH access is essential (need ssh client, sshd, ssh-keygen, scp, whatever dependencies there are). Busybox does not provide SSH functionality by itself, and recommends Dropbear (http://busybox.net/tinyutils.html). I would like to be quite sure that DropBear has the functionality and the security that the target market requires. So far, what I see in the docs is as follows: * Judging by Changelog, Dropbear is in version 0.51, and the development is not very active. This may be because it is very stable and very secure, or may be because there are not many development resources. * Uses LibTomCrypt rather than SSL - can anyone comment on security/functionality? I see my choces as DropBear vs. OpenSSH, compiled and linked for busybox. I am not particularly concerned about CPU or RAM, but I have a rather serious shortage of (flash) storage in the system. In our estimate, OpenSSH will take at least 10 times more storage than DropBear (between 1.2 and 1.5M rather than 110K Dropbear claims). What I am interested to know is whether DropBear is a good substitute for OpenSSH in terms of: * functionality * full compatibility * security * stability * etc. Any comments/experiences?

RE: SNMP: GET/SET vs. TRAP
Hi, Conceptually, there's a big difference between get/set and traps: get/set messages in SNMP are always requested by the management application and responded to by the SNMP agent. Traps, OTOH, are messages that are sent, unsolicited, from the agent to notify the management app of something of interest that has happened without having to wait for polling.

The XML files are generated by our own software so some of us though that maybe we can get rid of validation of the input and go straight to event handling using SAX parsers. My concern with this approach is that it sounds like we'll end up with a hand-written parser for very specific version of the input schema, which will require us to keep the code in pace with changes in the schema. Instead, I was wondering what would be the best way to ask the XML parser to validate the input. Maybe some tool which converts an XML schema to tightly integrated C++ code would do the trick?

[OT] Looking for a Linux embedded web server developer
Hi, I'm looking for a programmer to develop the web-based management part of a Linux appliance. The web server will NOT be Apache, but something much lighter (I'm leaning towards Cherokee right now, but can be convinced otherwise). The appliance is a rack-mounted PC runnning Debian 4.0. The web-based management requirements are pretty straightforward - reading/writing some configuration data, displaying status, etc. Development will be in the Rosh-Ha'ayin industrial zone, with the option to do some of the work off-site. If you have the skills for such a project, and are available over the next couple of week, please write me. Note that we're not hiring full-time (yet) - this is currently a one-time subcontracting job. If you can't provide a cheshbonit, we can work something out. Companies who can develop this on an outsourcing basis are also welcome to contact me.

Re: debian netinst q
Hi, Regarding root, IIRC, 'sudo' is configured to allow the user to get root access, e.g., 'sudo bash' should give you a root shell. This is the approach taken by Ubuntu as well - root itself is disabled, all root work done via sudo. The idea behind this is better security. I'm not ocnvinced that this is the case, but that's the intent.

All is fine safe a couple of minor things: Installer did not asked me if want graphical login, set gdm or something like that automatically, second it did not asked for root passwd and set something that I do not know and it did not asked me if I want grub or lilo and set grub (I definetely prefer lilo!). How did you boot the installer? If you just pressed enter at the first installer screen it should have presented you with a textual installer that by default would have asked you for root password and also for your computer tasks, if you chose as a task Desktop it automatically installs X11 with GDM and the whole Gnome desktop environment. I see. Can I have X11 without GDM Gnome etc? .. I've never seen the installer not ask for a root password so I don't know how you could have got to such a state.
