Hey, I have rather new installation of xen, dom0 is running ntpd and is perfectly in time. All domU''s are ~23s in future. Running ntpd on the domU''s seem to have no effect, /proc/sys/xen/independent_wallclock appears to have no effect. I''m running xen-unstable and 2.6.16-rc4 in AMD64 box. Any tip would be appricated. Thanks, -- ++ytti

Hi, It seems there is a problem regarding ControlMaster and scp'ing a file depending on the current working directory: $ cd ~/Personnel $ scp -o ControlMaster=yes cox.jpg host.local: muxserver_listen bind(): No such file or directory lost connection $ scp -o ControlMaster=no cox.jpg host.local: cox.jpg 100% 222KB 222.1KB/s 00:00 $ cd $ scp -o

Dear Mailing List We are using a ControlMaster with a short ControlPersist to access the bastion host which then gives access to customer hosts. Our Information Security Manager would like to disallow the ControlMaster. His attack scenario is an admin workstation with a compromised root account. An attacker can then use the ControlMaster to trivially get shell access on the bastion host

Real networks use either PREC (as it maps 1:1 to 802.1p and MPLS TC) or DSCP. Interactive SSH uses PREC 0x0, which is just best-effort and DSCP 0x4 which has no standard meaning (found network where DSCP 0x4 was dropped, completely, as it didn't hit any defined/allowed QoS class, obviously misconfig, BE class should eat anything not already defined) Should interactive use TOS value which has

I use ControlMaster auto (along with ControlPath) in my ssh config and find it very handy. I have noticed an annoying behavior, though: it seems that if there is no existing master connection and ssh creates a new one, the master connection process that is started has its stderr left open. This has manifested itself in two ways so far: (1) When using ssh day-to-day, I may be doing some work and

Consider this topology domain1-server1 domain2-server2 | | laptop - domain1-server1 ---- domain2-server1 Laptop has two ssh identities, domain1 and domain2. I don't wish to store identity locally in any of the servers. As far as I understand, there isn't any way to limit ssh-agent to allow only signing

Hi, Not sure if this anyone else is interested in this but to me it seems to make sense to use different control session multiplexer sockets for bulk and interactive workloads.

Speedbumps make sense sometimes, An attacker getting root on the jumphost gets immediate control of any _current_ persistent connections and new connections. Without ControlMaster it's a _lot_ harder to take

There is a race in the setup of the ControlMaster socket in auto mode, as illustrated by the following command line: ssh -oControlMaster=auto -oControlPath=sock localhost 'sleep 1; echo 1' & ssh -oControlMaster=auto -oControlPath=sock localhost 'sleep 2; echo 2' & Both of the commands will try to start up as a control client, find that sock does not exist, and switch into
