[Bug 1254085] Re: ssh fails to connect to VPN host - hangs at 'expecting SSH2_MSG_KEX_ECDH_REPLY'
Has there been any recent updates on this? I have a network setup with tunnels between Cisco routers as the egress points for each remote site and am having the same problems when attempting to SSH from a host inside of one site to the other. Again, MTU related. I hope there is a permanent fix in the works as it is cumbersome to have to change the MTU of each individual machine. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1254085 Title: ssh fails to connect to VPN host - hangs at 'expecting SSH2_MSG_KEX_ECDH_REPLY' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1254085/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Since the DF bit is set and PMTUD is being disobeyed, I discovered that MSS is obeyed. Therefore, I resolved my problems by doing the overhead math and setting the MSS adjust parameter on the LAN facing interfaces of my routers. This workaround is definitely more scalable than changing the system MTU on all my machines. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1254085 Title: ssh fails to connect to VPN host - hangs at 'expecting SSH2_MSG_KEX_ECDH_REPLY' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1254085/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 611330] Re: ssh hangs after login when using broadcom wifi
I'm having this same problem using the 'wl.ko' module for an Asus 1015PN Netbook running Maverick. In order to get SSH working at all, I first have to remove the module altogether. sudo rmmod wl Then I connect via a wired connection and SSH works. If I leave the module inserted and just disconnect. SSH will not work via a wired connection. I've been messing with this for two days now and have made no progress towards a fix or work around.

After extensive troubleshooting, I believe this to be a problem with the driver. I have setup the same version of Ubuntu/SSH on an iBook G4 (using the Broadcom driver) and SSH works fine.

[Bug 621509] Re: mysqld randomly causes system to not respond to commands
Clint, I appreciate your assistance with this but I am sorry to say that I believe I've wasted your time. I did some intensive digging on this and discovered that all signs point to a hardware issue on one of the SCSI buses. MySQL appeared to be the trigger; with the most disk writes/reads. It looks as if a hard drive might be going south. I receive a fatal error message when attempting to run OpenBoot tests on the SCSI bus. Which, in retrospect, makes sense as to why occasionally I would experience a hardware hang on reboots every now and again as well as why a hard boot seems to be the only way to recover. Either way, my new system will be resolving these errors. Again, I appreciate your prompt responses and I apologize for wasting your time.

[Bug 621509] Re: mysqld randomly causes system to not respond to commands
Clint, the last time this happened, I watched the system attempt to reboot when issued from command line via console. It appears the reboot sequence hangs on attempting to halt mysqld. As far as I can tell, I belive something in conjuction with Cacti and MySQL is causing this problem. It seems to happen when Cacti is still waiting for a response from a busy client it is monitoring and then the poller fires up another check while the one prior is still waiting. Once enough of these get backed up, it does something to cause mysqld to go rogue and that's when my problems start. I might also add that I have spine running with Cacti which was not a default package for 8.04. Thus, I pulled down spine from the 8.10 respositories as well as all the necessary dependencies. I fear this might be the root cause. Either way, I am planning on replacing this system all together with a new one, at which time it will run 10.04. So in short, I believe something I did might be causing this. Once I port my configs over to the new system, I shall see if the problem follows. -- mysqld randomly causes system to not respond to commands https://bugs.launchpad.net/bugs/621509 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-5.1 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Public bug reported: Binary package hint: mysql-server Once in a great while, my system becomes unresponsive to basic commands. This includes background commands such as anything run under cron and even syslog. I can still ssh to the machine, however any system level commands fail to run, even reboot.
