similar to: ssh_exchange_identification: Connection closed by remote host

greetings, I am setting up Centos 6 i686 remotely, on a new VPS. A problem I have is that I cannot set password for new users. I have created one with useradd -m new_user but when I type passwd new_user this is the result: [root at vps ~]# passwd new_user Changing password for user new_user New password: Retype new password: passwd: Authentication token manipulation error [root at vps

Greetings, I run my own email server for some domains I administer, on a centos vps server with a very small number of users. The only services are smtp, imap/pop, webmail Everything was running without problems until this morning. I left home for 1/2 hours, and when I came back everything had become about 100x slower (seriously!). The services were/are still all up and running, but practically

Hi, I'm getting this error when I ssh to the servers. ssh_exchange_identification: Connection closed by remote host I added /etc/hosts.allow and it actually worked once and if I tried again I get the same error. OpenSSH_3.6.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090702f debug1: Reading configuration data /usr/local/etc/ssh_config debug1: Rhosts Authentication disabled,

I'm randomly getting the following error on a server from various remote hosts: ssh_exchange_identification: Connection closed by remote host The server is running OpenSSH 4.5p1 w/GSSAPI Key Exchange patch. The hosts connecting to it should all be using OpenSSH 5.0p1 w/GSSAPI Key Exchange patch and using gssapi-keyex authentication. Normally, when I've seen this error, it means

Hello, I may need to set up soon a Linux VPS, to be used almost exclusively for handling email (as in "2GB of disk space, 2GB/month of bandwidth would be surely enough") with a fully customized postfix/procmail/dovecot setup. I'd prefer to use Centos, which I already use and know. One reason why I'm asking this here is that I'd really like to be sure, before I go for it,

Hello, when one has physical access to a computer, he can run something like tripwire, with keys and checksum on a separate, write-only media, to verify the integrity of the system. What if the system is a remote one (in my case Centos 4.3 on a User Mode Linux VPS some hundred of KMs from here)? Does it still make sense to run tripwire remotely? If yes, how, since you cannot plug a floppy or

Hello, I am testing ssh with occasional network disconnection between server and client during these days. I found ssh sometimes hangs if the disconnection happens after the connection is established but before ssh_exchange_identification completes. The ssh configuration files show that both client and server alive options are set. In /etc/ssh/ssh_config: # Send keepalive messages to the server.

Greetings, I have seen via google that this very problem was already discussed on several lists some months ago, but the archives report no solution. I have a remote server with dovecot 1.0-0_12.beta8 on Centos 4.3. IMAP works just fine: I can read email from both Squirrelmail via web and Kmail. Now I have created an ssl certificate on the server, and I'm trying to retrieve email via pop3s

Guys, I think that I have ran into a bug. I am running openbsd 2.8 and I upgraded to the lastest verison of openssh 2.9 but when I did that it started giving me this error "ssh_exchange_identification: Connection closed by remote host" when I try to log into the machine even when I am on the machine and try to ssh localhost it gives me the same message. I have read every FAQ I could find

hello, i built an ssh 2.5.1p2 package for solaris. it's installed into /usr/local (with sysconfdir=/etc) on an administrative host with write access to /usr/local. other hosts nfs mount /usr/local. i had a script copy the following files generated from the package install into each host's /etc directory: primes ssh_prng_cmds sshd_config ssh_config then ran

I'm receiving the centos-request in digest mode. Using Fedora 10 and Evolution. When I tried to reply to a centos-request message inside the digest, the result doesn't seem to look right. I cut/paste the proper subject line (replacing the CentOS Digest, Vol NN, Issue nn text), but some have complained that this approach doesn't allow the original question and replies to be threaded.

sorry for the vague subject, but I couldn't find a better one. I have the website http://digifreedom.net running on a Centos 4 VPS with Apache and Drupal 6.10 . This is a multisite Drupal setup: only one installation, with subdirectories in sites/, and a separate mysql database for each website. For several reasons, I had setup DNS, drupal and everything to work without the www prefix on

Greetings, I have just been given a VPS with a fresh, minimal Centos 4.2 installation. When I ran "yum update" it went on updating some tenths of packages and signalled this error: Updating : perl ####################### [24/88] Updating : rpm-python ####################### [25/88] Updating : MAKEDEV

Greetings, I have had to reinstall my email server on another Linux (centos 7.6) VPS, with a newer version of dovecot, other software and a brand new letsencrypt certificate just for email withpostfix and dovecot (that certificate works fine with postfix). Output of dovecot --version and dovecot -n on the new server is below. Now, messages ARE delivered in the right IMAP mailboxes, but when I try

pc1(LANa) ----poor connection ----> VPS <--------- PC2(LANb) pc1 and pc2 used to connected directly with tinc, since pc1 used to have WAN IP(pppoe), but the pppoe IP is not WAN IP anymore (ISP changed to let all ADSL user in a LAN). if I let the two pc connect to a VPS with tinc, can later connections between pc1 and pc2 be directly ? for example, ssh from pc1 to pc2 but not proxyed by

Hi all, I've been asked by a college to setup a monitor to monitor a Windows network, but on internet usage. They want to have detailed usage, i.e. on a per IP / PC basis, and if possible to get stats for every protocol, and see over a period of time what goes on. My first though wat ntop, which does all of this, but it doesn't save the data in a DB, so if the server reboots the stats

Hi, there is a remote (VPS) Centos 4.2 server which *may* have been compromised. Reinstalling everything from scratch isn't a problem, it may even be an occasion to improve a few things, the question is another. There are backups of necessary shell script, ASCII configuration files and more or less important email (maildir format, if it matters) including messages with binary attachments in
