[Touch-packages] [Bug 708493] Re: Can't login anymore: Read from socket failed: Connection reset by peer
Sorry folks, but as part of the bug clean up ahead of 16.04 LTS I'm marking this as invalid because it affects an Ubuntu release which is now unsupported. If you can still recreate this bug in a supported release please do open a new bug and we can triage it for consideration in the 16.04 LTS development cycle. ** Changed in: openssh (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/708493 Title: Can't login anymore: Read from socket failed: Connection reset by peer Status in openssh package in Ubuntu: Invalid Status in openssh package in Debian: New Bug description: After todays update to 1:5.7p1-1ubuntu1 I cannot login to SOME (!) of my servers.

[Touch-packages] [Bug 708493] Re: Can't login anymore: Read from socket failed: Connection reset by peer
Hello, Not sure it is the same problem here, but I cannot connect to my machine if go through NAT. If I connect directly from LAN everything works, but if I use the external IP, then I get connection reset after debug1: SSH2_MSG_KEXINIT sent. Client and server is the same machine. I tried to set MTU to 1400 and 400 with no effect, also changed the net.ipv4.tcp_rmem setting and tried different cipher algorithms with no luck.

Hi guys. Without apparent reason suddenly I wasn't enable to make a ssh connection with my production server. When run a ssh -v I get "expecting SSH2_MSG_KEX_ECDH_REPLY connection closed". After spend a lot of time looking for a solution, I solve my problem just uncommenting two lines in my /etc/ssh/ssh_config file. I uncommented lines beginning with "Ciphers ..." and "MACs ".

Re: [Touch-packages] [Bug 708493] Re: Can't login anymore: Read from socket failed: Connection reset by peer
Did this used to work ? This bug is due to a ssh version change ... Sounds like you may have a firewall issue, if you are trying to connect via a nated connection for the 1st time. Use tcpdump on your server ... and analyze the traffic on port 22 Compare the traffic, when you connect locally and then via the nated connection. Use the verbose settings of ssh to get more information before posting again .. On 20 February 2015 at 20:25, Mike wrote: > Thanks, but a specific client is not an option.

Why are you testing a NATED address from the same server ( client and server ) ?
