I've got my Ultra"-slow" 2 up and running with gentoo...works nicely. However I need openssh installed. When I try to emerge it I get the following error:

!!! all ebuilds that could satisfy "app-crypt/mit-krb5" have been masked.
!!! (dependency required by "net-misc/openssh-3.7.1_p1" [ebuild])

Now I can just download it by hand and install it without a problem. But I'm curious why mit-krb5 is masked...is there any way to emerge ssh without it?

Thanks in Advance,
Gary

This may be related to the recent critical bug in ssh, which is why openssh was pushed to the next release in portage faster than usual, although there are still problems with the deps. A
Code:
 env USE="-kerberos" emerge -p openssh

Should do the job.

openssh-3.7.1p1-r1 fixes this issue. however there are issues building it against openssl-0.9.7 (if you are using ACCEPT_KEYWORDS=~sparc).

I guess you are refering to this, since i have the problem then emerge-ing openssh on my system that uses the "~sparc".

Output from emerge:

!!! ERROR: net-misc/openssh-3.7.1_p1-r1 failed.

Is there a workaround to this problem?
(Beside setting ACCEPT_KEYWORDS to "sparc" and downgrade openssl-0.9.7b)

TIA

Oh, sorry for not getting back to you

Short answer

rm /usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.2.3/include/openssl/bn.h
emerge openssh

long answer

Yeah that makes 4 upgrades, and this one wont compile correctly on my Ultra 5. It panics with an error, I will post the error after I generate it again. (forgot to do it when I saw it)

:evil: :x

Edit: and nevermind I saw the above, pays to read the whole thread (i'm getting tired)

No worries mate... thanks for the answers!

Just out of curiousity: Why keep a copy of the "bn.h" file under /usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.2.3/include/openssl/
All the other openssl includes (including bn.h) are kept under /usr/include/openssl as usual...

Not sure, you'd have to ask the GCC folks on that.

Why are people using openssh?? That group shows up far too often on bugtraq, gotta be crazy to be running stuff from them on serious boxes....maybe gentoo isn't serious stuff?

Note to the illiterate: SSH license is satisfied merely by running linux, regardless of end use.

Maybe because openssh are more honest about their vulnerability reporting than certain other groups?

I was having some similar problems with an openSSH emerge. I had tried just re-emerging GCC with the previous version of openSSH on, but it still wouldn't let me emerge OpenSSH. I kept getting

Code:

gcc -o ssh ssh.o readconf.o clientloop.o sshtty.o sshconnect.o sshconnect1.o sshconnect2.o -L. -Lopenbsd-compat/  -lssh -lopenbsd-compat -lutil -lz -lnsl -lcrypto -lcrypt
./libssh.a(rsa.o)(.text+0x2a4): In function `rsa_generate_additional_parameters':
: undefined reference to `BN_mod'
./libssh.a(rsa.o)(.text+0x2d6): In function `rsa_generate_additional_parameters':
: undefined reference to `BN_mod'
collect2: ld returned 1 exit status
make: *** [ssh] Error 1
make: *** Waiting for unfinished jobs....

!!! ERROR: net-misc/openssh-3.7.1_p2-r1 failed.
!!! Function src_compile, Line 101, Exitcode 2
!!! compile problem


I resolved my issues by unmerging openSSH remeging gcc and then emerging openSSH.

Hope that helps.

You didn't understand a thing if you really think what you wrote!
OpenSSH is VERY serious piece of software. (Gentoo too :-)) What do you use for remoteshell program if not OpenSSH ?
And beside if you use the binaries from e.g. www.ssh.com (closed source) you get a lot more vulnerabilities just nobody knows about them.
