General :: Debug Ssh Permissions And Keys?
Nov 15, 2010
I am trying to debug ssh permissions and keys. I am able to connect as root. However, I am unable to login as a new user (e.g., newuser). I have been trying to ssh as localhost to debug the issue. For example:
>ssh -vvvv newuser@localhost
will yield a lot of information. I think this is the relevant section, however, I am unable to resolve:
debug1: Host 'localhost' is known and matches the RSA host key.
debug1: Found key in /root/.ssh/known_hosts:2
debug2: bits set: 533/1024

I don't know if this is a configuration issue or a hardware issue, but I have a Kinesis Advantage USB keyboard and for some reason the F3-F5 keys aren't responding as they used to. They don't respond to anything and, when I tried using F5 on Emacs, it said <XF86AudioNext> is undefined, so I guess it's a weird mapping problem.
Any idea how I could remap them to the original meaning?

I'm running Debian (Squeeze) and I have a toshiba portege m700. It has five buttons on the front just under the screen, which are the only ones accessible when you flip the screen over into tablet mode. One of them is for rotating the screen, and another is for switching to external display. I want to remap the remaining three to control, alt and super so that I can use shortcuts with the stylusThe problem is, when I used showkey to find out the key codes, I found out that each button generates more than one key code:Button 1:
key 126 press >> super_r, although this is distinct from the actual super key (125)
key 7 press >> 6
key 7 release
key 126 release

I have a problem with my external hdd, I mounted it manually and in the mount table it says ive got rw permissions. But when i try to change permissions it says:
chmod: changing permissions of `whatever': read-only filesystem.
This is my mount table:
[root@localhost ExtHDD]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)

/var/log/debug gets lots of messages any time an LVM snapshot is setup (lvcreate --size ${size}k --snapshot --name "$LVM_snapshot_device" "$LVM_device"). Here is a recent sample.

I need debug my program and I need something like a virtual microphone. I would like device "microphone" where I can put sound file and this file will be input for microphone stream. And in application I get this stream from this "microphone"
File -> Microphone -> Application
is it possible?
something like bash command should by very very useful:
aplay --device=mic my_microphone.wav to run a microphone stream

Ive been messing around on a Solaris box, installing precompiled lib/programs from the repos by extracting them and placing them in my home dir. It seems everything ive tried sofar works, except for irssi. I get the following error:
$ ~/bin/irssi
ld.so.1: irssi: fatal: relocation error: file /export/home0/leem2/bin/irssi: symbol boot_DynaLoader: referenced symbol not found
Killed
I have run:
$ ldd /export/home0/leem2/bin/irssi
and it has no missing libs

Does anyone know if it is possible to make rules in a Makefile that would work like this:
> make debug module
or
> make module debug
where module can be any module that has a specific rule in the Makefile.
The thing I have is a Makefile with different rules that I compile like this:
> make module
What I would like is to add an option so I can compile whichever module with debug-information just by adding a debug to the make command. The debug-information I know how to do, the problem is how to make the Makefile work...

I am trying to debug a script that another person wrote. I am not very strong understanding awk.
cat ${origfile} | awk '{sub("�14","
\page
");print $0 "par"}' >>${rtftempfile}
I know awk is doing some kind of manipulation of the acsii file ${origfile}, just not sure what.

I have a working build of crosstool - it was built for gcc 3.4.3 using glibc 2.3.5 going from 32-bit x86 linux to 64-bit alpha linux. As far as I can tell -- it compiles correctly (output of alpha emulation matches expected) but it has a major flaw. When I use the cross compiler and attempt to add detailed debug information, it compiles, but does not have the debug information. For example, when I execute:
> /home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc-3.4.3 -g -o hello main.c
OR
> /home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc-3.4.3 -gstabs -o hello main.c
I get a working alpha binary for hello world. BUT - when I run objdump - this is what I get
> /home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump -g hello
hello: file format elf64-alpha
/home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump: hello: no recognized debugging information
Frustratingly - if I use my x86 gcc version 3.4.6 to do the compilation (same arguments, just using the x86 compiler, not the cross compiler) - it correctly embeds the debug information.

I cannot ssh into an RHEL 5.5 server (192.168.20.104) from another RHEL 5.5 server (192.168.20.101) unless server debug is turned on 192.168.20.104, and even then, I have to wait several minutes before the connection is established. scp to and from the 104 server is also not working.Here is the debug output on the 101 server when server debug is not enabled on the 104 server-:

I'm interested in storing my SSH keys and gpg keys on a smartcard for added security. However, I'm a bit uncertain on a few points, which are as follows:
How many keys can I get on a card? I assume both SSH and GPG can store keys on the card. Is there a limit to key size? I see a lot of cards saying they support 2048-bit keys, what about larger sizes? Hardware: can anyone recommend a card/reader combination that works well? I've done a fair amount of research and it seems PC/SC readers can be a bit iffy - is this your experience? Have I missed anything I should be asking? Are there any other hurdles?
I'm aware fsf europe give away cards with membership - I'm not sure I want to join, but... are these cards any good?

Just trying to get some packages upgraded on Debian/Lenny, esp. PHP5, but I always get the NO_PUBKEY error from php53.dotdeb.org.
I resolved the same problem with security.debian.org by doing:
apt-get install debian-keyring debian-archive-keyring
apt-key update
but no luck on dotdeb. trying:
gpg --keyserver keys.gnupg.net --recv-key A2098A6E

I have gpg (not sure how to check the version) installed and running nicely. I am attempting to publicize my public RSA key to various key servers, but even tho everything seems to work nicely in actuality it does not.
Code:
When I check that particular (and others after similar attempts) keyserver for my e-mail address it only finds my old, revoked key. How can I get publishing my RSA key from the command line to work in actuality?
