Server :: Ssh Freeze After Logging To The CentOS 5.4 Server?
Nov 15, 2010
I have 2 servers running CentOS 5.4 Final, one is 32 bit and the other is x86_64.When I ssh to either server, the session will freeze after a while and I cannot type anything except I close the term. This has happened before, and I thougthat was caused by iptables' rulesBut now I turned off iptables and the problem remains.I tried tcpdump on my machine(client running OpenSUSE 11.2), and it shows that after the freezing, client will still sent ack message to the server.So I think this may be caused by the server.Note that I can ping the server smoothly.Does anybody meet this problem before

I am having trouble logging into a newly installed CentOS 5.3 box. I can SSH into the machine with root but can not do so with any normal users. I get the error, "connection refused." My firewall is currently turned off.

I have installed CentOS 5.5 along with the Samba package. I have it configured (i believe), but when I try to access a share, it is not accepting my UN/PW. I have copied the smb.conf file from a working computer over to this one, but it is still not accepting my login. Anyone know of any other files I should check?
I have moved a working smb.conf file to this new box, and both computers have the same UN/PW's

I am having a problem with bringing up a two node cluster.
It picks up a cluster configuration file from another cluster on the network where of course it does not find the local node
I've disabled openais, change the configuration to use a different ring but it is still happening.
I get the following error message code...
Is there a way to boost the logging for cman and openais so I can get more clues as to why it it is happening? I've only seen postings telling how to do it for resource manager .

I want to use my CentOS-Server for logging incoming phone calls using an AVM Fritz-Card.It should also be possible to notify clients (Linux and Windows) on incoming calls, or there should at least be a web-frontend.Is there any software like that in the CentOS-Repository available?Or is there another software like that, that is easy to install? I already asked google (an i will go on), but I couldn't exactly find what I want.

we need to log web access of a certain set of users for analysis. We decided to setup a proxy server which just logs all the requests but does not do anything else like caching/access control etc.All users will be using a fixed set of computers and hence we can redirect their requests to the proxy. I came across Squid, but found it to be too heavy for our requirements. Is there any other proxy-server software that is good enough for what we want or is Squid the only way?

I have an issue with users logging into a server. There are multiple (5 or so) database admins that have to log into a windows 2003 server and from there log into a red hat server. Once they are in the rhel box they execute an app (let's say xclock) that gives them an xwindows session on their desktop. Currently only one person can do this at a time, but they have asked me to configure it to allow multiple users to log into the red hat box from the windows server and run an xwindow.

i am learning about the ability to utilize the rsyslog ability to be a server for the logging info from other machines. i have did it successfully, and i get logs from other machines through the network, but i don't know where i can set the server for my desire act on these logs that come from the network. i essence the question is: why the server put some logs at /var/log/messages, and others not ?

Perhaps there is something on the net about this, however I couldn't find the correct keywords (and there are many other but similar problems) and didn't find anything. You know that when logging in, if you enter a wrong password, you'll have to wait a few seconds before giving it another try to avoid bruteforcing. However, when I enter the correct password in 11.04, it makes me wait a few seconds and then loads my desktop (fluxbox in my case, but the same problem remains in Unity).

I recently installed ubuntu 10.10 and am completely new to linux. Something I recently noticed is that my whole system will freeze 2 times after logging back in, but after that it works fine. I will log in, then it will work fine, but shortly after it will completely freeze. After about a minute, it will unfreeze and everything will work fine. Then after a little longer, the exact same thing will occur. After the second freeze and unfreeze, it never occurs again until I log out and log back in. I do not believe this occurs when first starting the computer.

I have been looking into how to get logging on my SSH server. I would like to have logs similar to what normal FTPs would have when you connect and download/upload. But the only logging I have been able to find is either VERBOSE or DEBUG. Both of which seem to give too much information. It would be nice if there was a logging mode that was just commands sent to the server, does anyone know if this exists?

I want to login to my company's server (remote) from my room. I have the server address, so I use this command to login :
Code:
#ssh root@X.X.X.X
It waits for a very long time and then returns with error connection timed out port 22.
I configured these settings in the remote server :
Code:
#/etc/init.d/iptables stop
Then I connect via ssh from my home but still the same error.
Then in the config file /etc/ssh/sshd_config, I uncomment the line : ListenAddress 0.0.0.0
I connect via ssh again from home but still the same error.
The connection is not denied in hosts.deny and hosts.allow.
How do I get the connection up and running?

Whether I use ufw or firestarter to populate my iptables, my firewall logs get written to 3 different log files:/var/log/messages/var/log/kern.log/var/log/syslogI want to keep the logging turned on, but I'd rather it not log to syslog, as it's obscuring other events in syslog that I'd like to see. I'm using rsyslog on Ubuntu. I looked around online and found one person suggesting I add this to the top of rsyslog.conf:kern.* -/var/log/kern.logkern.* ~I did that and restarted rsyslog, but it's still logging to the same 3 files.

I'm guessing its possible but I can't seem to find any documentation on how to do this.I've tried playing with entries at the top of my syslog.conf file like:
*.* @172.20.10.1 # 1 server, works file
*.* @172.20.10.1,172.20.20.11 # doesn't work
*.* @172.20.10.1 172.20.20.11 # nor this
*.* @172.20.10.1,@172.20.20.11 # nor this
*.* @172.20.10.1 @172.20.20.11 # nor this

Is there somewhere in WHM where I can allow and disallow various ip addresses to login using PuTTY for SSH.OpenSSH Server, is not running (for security reasons).If OpenSSH is not running, is there a way to allow certain ip addresses only to use ssh.

I am having problems logging into my SME Linux server from a new Windows 7 machine. It sees the server on the network, but does not seem to be passing the windows login through to the Linux server (which is how all of the XP machines log in). When I try to log in using a valid username and password it goes nowhere and just says it is an invalid username and/or password. I had a Vista machine that could log into this Linux server so I do not think the Samba version is the problem.

Setup a new machine with Apache, identical setup to all the other machines I got, yet this one is logging hostnames instead of IPs.
"HostnameLookups" are "Off" and LogFormat settings are identical to all the other machines:
Code:
Added a new LogFormat directive:
Code:
And told the virtual hosts to use it:
Code:
This solved the problem, though I'm at a loss as to why I've got this behavior on just this one box and none of the others. OS is Debian Lenny, same version of Apache installed via Debian package.
My understanding from Apache doc [url] is that when "HostnameLookups" are "Off, "%h" will yield IP instead of hostname..
Code:
It features support for HTTPS, virtual hosting, CGI, SSI, IPv6, easy scripting and database integration, request/response filtering, many flexible authentication schemes, and more. Homepage: [url]
