[Bug 1811122] Re: Cannot use xrdp to login to sesman-Xvnc after 0.6.1-2ubuntu0.1

2019-01-21 Thread Neil Hoggarth
I can confirm that the 0.6.1-2ubuntu0.3 version from the security-
proposed PPA works on my test 16.04 system, both as an upgrade from
0.6.1-2, and as an upgrade from 0.6.1-2ubuntu0.1.

2019-01-14 Thread Neil Hoggarth
I tried installing 0.6.1-2ubuntu0.2 from the ubuntu-security-proposed
PPA, but the new version appears to have the same sort of problem as
0.6.1-2ubuntu0.1: the connection between the session manager and Xvnc
fails with the "password failed", "error - problem connecting" messages
in the connection log window.

[Bug 1754294] Re: After last updated libcurl3 on libcurl4, some apps are removed.

2018-06-13 Thread Neil Hoggarth
I have the same problem as William Jojo (w-jojo) reported in #54.

The Shibboleth authentication package (libapache2-mod-shib2) in Bionic
Universe depends on libcurl3 (via libxmltooling7). I'm told in bug
#1776489 that this is because upstream Shibboleth hasn't yet released a
version that works with OpenSSL 1.1, so it genuinely needs
libcurl3/libssl1.0.0.

Even when Shibboleth 3 is released by upstream, presumably it will not
appear in Bionic, except perhaps as a backport?

So we need a solution for proper libcurl3 / libcurl4 co-existence in
Bionic, if the Shibboleth SSO stack is going to work in the current LTS
cycle.

[Bug 1776489] [NEW] libxmltooling7 depends on libcurl3, which has been replaced by libcurl4 in Bionic

2018-06-12 Thread Neil Hoggarth
Public bug reported:

I am attempting to make use of libapache2-mod-shib2 on Ubuntu 18.04 LTS.

Shibboleth installs and works as expected on top of a minimal Ubuntu
install. However it has a dependency on libcurl3 (via libxmltooling7).

Almost all of the other libcurl using packages on Ubuntu 18.04 depend on
libcurl4.

libcurl4 is declared to conflict with libcurl3.

Therefore, almost no other libcurl using packages in 18.04 can co-exist
with the Shibboleth packages.

[Bug 1570472] Re: Set systemd as default service provider

2016-10-24 Thread Neil Hoggarth
Upstart is still installed on desktop Xenial systems, even on a fresh
installation; the unity-greeter package depends on it. Attempting to
"apt-get remove upstart" also offers to remove the "ubuntu-desktop",
"unity", and "unity-greeter" packages, along with the "upstart" package.

So this bug prevents the use of Puppet from correctly managing any
services on a Xenial desktop system.

[Bug 409438] Re: Multi-user sec=krb5 NFSv4 client blocks when one user has an expired ticket

2009-10-29 Thread Neil Hoggarth
I have recently set up an Ubuntu 9.10 release candidate system for testing, and 
I am able to reproduce this 
problem there, too. My new test system does not us the automounter - I 
encounter the same problem with
a statically (fstab) mounted NFS4 sec=krb5 home directory tree and two 
kerberised login accounts.

It seems to to affect a wide range of kernel versions, both i386 and amd64 
architectures, and be 
observable/reproducible on any system using pam-krb5 for authentication/ticket 
acquisition and kerberised 
NFS4 home directories.

[Bug 409438] [NEW] Multi-user sec=krb5 NFSv4 client blocks when one user has an expired ticket

2009-08-05 Thread Neil Hoggarth
Public bug reported:

I have an Ubuntu 08.04.3 NFSv4 server and a number of NFSv4 clients, 
also running Ubuntu 08.04.3.

The clients use autofs to mount user home directories from the server.

I use Kerberos to authenticate the users logging into the clients (using 
pam_krb5), and require Kerberos authentication of NFS traffic via the
sec=krb5 export and mount options.

Things seem to work normally on a workstation used by only one user - 
people can log in, get, valid kerberos tickets from the KDC and their 
home directory mounts automatically.

However, a problem arises on multi-user systems: if one user (say user 
A) has successfully logged in and left themselves logged in such that 
their Kerberos TGT has expired, then a second user (user B) attempts 
to log into the same system then the attempt to access the home 
directory of user B blocks indefinately. If user A subsequently 
obtains a new Kerberos TGT then the login attempt belonging to user B 
unblocks and runs to a successful completion.

While B is blocked, the kernel logs the following error message over 
and over again, at a very high rate (3000-6000 times a second):

Aug  5 11:37:14 ulf kernel: [3099781.024499] Error: state recovery failed on 
NFSv4 server 163.1.248.155 with error 13
Aug  5 11:37:14 ulf kernel: [3099781.025007] Error: state recovery failed on 
NFSv4 server 163.1.248.155 with error 13
Aug  5 11:37:14 ulf kernel: [3099781.025483] Error: state recovery failed on 
NFSv4 server 163.1.248.155 with error 13

The symptoms that I am observing sound exactly like

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=446238

To be clear: I expect user A's access to NFS mounted filesystems to fail 
when their Kerberos tickets have expired, but I don't expect user B's 
access to the same filesystems to depend on user A.

For the record, I have been running linux-image-2.6.24-24-generic version 
2.6.24-24.54 from
hardy-proposed on my primary x86-64 workstation for the last two weeks. In that 
time I haven't 
experienced any of  the NFSv4 hang-ups that I was previously observing, and no 
instances of the

[Bug 81242] Re: postfix-ldap is linked against gnuTLS

2009-02-12 Thread Neil Hoggarth
I'm setting up some servers and workstations using Hardy, and just got bitten 
by this problem - default configuration of postfix is chrooted, postfix-ldap 
will not work against an LDAP server using SSL/TLS because the /dev/random and 
/dev/urandom devices are not present in the chroot, which prevents gnutls from 
initializing an SSL connection. It took me ages to find out what was wrong and 
how to work
around it.

Should the postfix package not be updated to mknod suitable devices in
/var/spool/postfix/dev on installation?
