Gidday everbody, We have just found an interesting issue regarding the sshd daemon on our SuSE system. For some reasons, the /usr/sbin/sshd process blocks SIGALRM as shown in the /proc/pid/status: $ cat /proc/`cat /var/run/sshd.init.pid`/status Name: sshd State: S (sleeping) SleepAVG: 0% [...] SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000002000 <-- SIGALRM is

Greetings- I'm running some USB DAHDI hardware on a system with a tickless kernel. The audio quality is quite poor. Could the tickless kernel be to blame? If so, when recompiling a kernel that is *not* tickless, is there a recommended KERNEL_HZ value? IIRC, older kernels used to be 1000, but newer ones are 250. Thoughts? --Tim

Hello, I am trying to build a custom kernel 2.6.24 from ubuntu with xen dom0 support. Does Xen support a tickless system (CONFIG_TICK_ONESHOT=y) and the realtime features of this kernel (CONFIG_PREEMPT=Y instead of CONFIG_PREEMP_VOLUNTARY)? Everytime, I set these options while configuring the kernel, the two settings are not regarded during kernel compilation. I also tried to build the

Hello everyone, I''ve always wondered - would dom0 be better off with a tickless kernel or not? In other words, can someone explain which choice to make with regards to CONFIG_NO_HZ? -- Stay in touch, Mark van Dijk. ,-------------------------------- ----------------------------'' Mon Aug 06 15:40 UTC 2012 Today is Pungenday, the 72nd day of Confusion in the

Hello All, It seems that 'getent group groupname' hangs on large groups for Solaris 8/9 running winbind. Currently running Samba 3.0.20 but also tried 3.0.10. 'ls -l' also hangs if listing a file created by a user who's primary group is too large(such as Domain Users). Users can still access the files but netbackups hang. The problem I am experiencing is found in the

This is a continuation of a discussion we were having on IRC. The problems with IRC are it's not recorded and it's hard to have deep technical conversations. I hope this is a decent summary. Problem simply stated: Certain NBD servers (qemu-nbd in particular) are able to simultaneously read and write on a socket. ie. They can be simultaneously reading a request and writing the reply to

klibc fails to build on ia64 because it has neither fork nor the ppoll syscalls. This patch marks the former in SYSCALLS.def, and puts a guard wrapper around the ppoll definition in ppoll.c Should these calls return ENOSYS rather than simply not existing on some systems? If yes, please apply this and I'll follow up with a patch shortly that does ENOSYS for this and pselect at least.

I've written the code to switch to the largest available video mode. As is, it is probably not very useful (because the font is probably barely legible on a 150dpi display and because I've not modified the background loading code). Would it be interesting to develop it further or would it be considered overbloat ? If yes, I have the problem of choosing the

I've traced the code of set_background quite a bit this w.e. and was wondering what would happen in the __unlikely case where there is no background for the main menu and one for a submenu. It looks to me that when the submenu is closed, set_background will be called with new_background == NULL, that current_background != NULL inside so that there will be a

Hello everyone, Today is exactly 10 years ago that tinc 1.0 was released. I would have hoped to celebrate this by releasing 1.0.22 and 1.1pre8 today, but this will instead happen in one week. Tinc 1.1 is close to becoming stable, and I hope to release 1.1.0 before the end of the year. The main features of tinc 1.1 are the improved security over tinc 1.0, and a much nicer interface that makes it

So, we just found some ugly behaviour of OpenSSH on Solaris. Sometimes, it seems, sshd gets started with SIGCHLD blocked, this, apparently, being the setting of sshd's parent (a shell no doubt); signal blocking is inherited across exec*(). I don't know exactly which shell, or what really is at fault, but it happens. The problem is that the code in collect_children() first blocks SIGCHLD

Hi, I've an up and running tinc vpn between my laptop and my office computer (on which I've root access if needs be). From where I'm sitting right now, UDP packets are dropped. TcpOnly has solved the problem for the tinc part and I can still connect to my office. I'd like to access some important <cough>irc</cough> UDP-only services. Do I have a

Hi, I've two computers, one with Debian the other with Ubuntu. The Debian computer has v1.0.14, the Ubuntu v1.0.11. They do not manage to connect with error "wrong keylength": the Ubuntu computer sends a 512 byte key to the Debian computer which expects a 256 byte key. Is it expected ? Is there a configuration option somewhere that I've set differently on

Hi there, I have a problem when I try to create a new user with swat. I use binaries of Samba 2.2.2 coming from www.samba.org, or from www.sunfreeware.com on Solaris 2.6 and on 8. I compiled the sources and the result is the same. When I click on "Add New User" (Server Password Management), I receive a nearly blank page: I can only see the samba gif on top and the user is not
