Hi
I dropped a new remote client mode NS2 in the field.
It is loaded with r21061.
I can't loggin with key nor with password but I have http(s) access: the server drops the connection before I can enter the password or key passphrase.
I checked my usual settings but I can't find my mistake.
In the same network there is also a client mode wrt54gl1.1 r12533 to which I can remotely login fine.
Both are clients to a WAP wrt54gl1.1 r12533 too and the main router is an other wrt54gl1.1 r12533 also in client mode.
All 4 boxes have each own port forwards for http & ssh but only the NS2 fails for ssh.
Please is there something new in r21061 compared to r14896 about ssh or something that could prevent login (I noticed a new "Local DNS" in services and 5 nice new features in the firewall GUI but I don't use any at the moment).
The server log just shows:
Code:
Jun 30 20:58:54 ns2 authpriv.info dropbear[21864]: Child connection from my_remote_ip:36272

and my remote ssh client verbose -vvv ends this way:
Code:
...
debug2: kex_parse_kexinit: first_kex_follows 0
debug2: kex_parse_kexinit: reserved 0
debug2: mac_setup: found hmac-md5
debug1: kex: server->client aes128-ctr hmac-md5 none
debug2: mac_setup: found hmac-md5
debug1: kex: client->server aes128-ctr hmac-md5 none
debug2: dh_gen_key: priv key bits set: 121/256
debug2: bits set: 1046/2048
debug1: sending SSH2_MSG_KEXDH_INIT
debug1: expecting SSH2_MSG_KEXDH_REPLY
Connection closed by MY.MAIN.IP.ADR

just the same as a working router that tells:
Code:
...
debug2: kex_parse_kexinit: first_kex_follows 0
debug2: kex_parse_kexinit: reserved 0
debug2: mac_setup: found hmac-md5
debug1: kex: server->client aes128-ctr hmac-md5 none

debug2: dh_gen_key: priv key bits set: 129/256
debug2: bits set: 517/1024
debug1: sending SSH2_MSG_KEXDH_INIT
debug1: expecting SSH2_MSG_KEXDH_REPLY
debug1: Server host key: RSA 83:bc:e2:c4:c6:40:57:45:0a:61:25:24:a5:0f:35:a7
debug3: put_host_port: [MY.MAIN.IP.ADR]:ForwardedPort1
debug3: put_host_port: [local HostsAlias]:ForwardedPort1
debug3: load_hostkeys: loading entries for host "[local HostsAlias]:ForwardedPort1" from file "/home/me/.ssh/known_hosts"
debug3: load_hostkeys: found key type RSA in file /home/me/.ssh/known_hosts:169
... and so on until the passphrase


(I tried putty too:
Quote:
PuTTY Fatal Error Server unexpectedly closed network connection


Thanks for advises

[EDIT]
behind the ns2 I also added a tplink wr841dn v8.2 with r21676 as a WAP in which I can remote ssh fine too.

[EDIT]
same issue when trying to connect from local network

here is a fresh log:

Hi Sash
"...fixed now" : do you mean in r22118 ?
[EDIT] Ok, looked at trac and alt downloads. It was fixed just some hours/days after 21061 release I got from Router DB which still advises 21061.
