===== SSH Config =====

The following text can be saved as is to your ''%%.ssh%%'' directory in a file named ''%%config%%'' which enables you to connect to our servers using for example ''%%ssh grapex%%''

OPEN TODOs:


  * add missing servers (and post into dev when you did)
  * add comments explaining the tasks / operations of the server

==== Issues ====

With some newer OpenSSH version it was not possible to login into 'sg02'. The following fix solves the issue, just add the following line into ~/.ssh/config:

<code>
PubkeyAcceptedKeyTypes +ssh-rsa
</code>
if you have the issue that ssh hangs while connecting to corpex machines over wireguard:

<code>
ssh -vvv host
....
debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY
</code>
the solution is to find your WAN device (the one that you use to connect to the internet) and get its “mtu” value:

<code>
ifconfig
wlp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.178.60  netmask 255.255.255.0  broadcast 192.168.178.255
        inet6 fe30::3db0:d350:5e33:3b24  prefixlen 64  scopeid 0x20<link>
        inet6 2a03:4131:2319:3800:393e:e3fb:b352:37ad  prefixlen 64  scopeid 0x0<global>
        ether 34:f3:9a:a3:23:b2  txqueuelen 1000  (Ethernet)
        RX packets 18702723  bytes 10397352559 (9.6 GiB)
        RX errors 0  dropped 482633  overruns 0  frame 0
        TX packets 12932568  bytes 6226280735 (5.7 GiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
</code>
in this case it would be 1500. now you need to make sure that the mtu of the wireguard device (for me it is “corpex” since my wireguard config is called “corpex.conf”) is lower than that:

<code>
sudo ifconfig corpex mtu 1400
</code>
for me the 1400 works fine, but you may need to experiment. if you set the number very low (e.g. < 1000), you will produce a lot of network packets, and things will be slow and inefficient, but it should still work.
