Networking :: MacOSX To RHEL5 / 6 Ssh Connection Timeout
Apr 1, 2011
I have a user using Mac OSX and ssh-ing to a couple of Redhat servers, one running RHEL5 and the other RHEL6. The user's connection seems to be timing out after 60 minutes or so of inactivity. The user is on the same subnet as the servers. Both servers have the same sshd_config files with the following entries with regards to timeout:
In a nutshell, his office Mac keeps getting dropped off both machines. Other machines, including the Mac he logs in with from home doesn't get timed out and keep the connection open. The log files are unremarkable and the switch port shows no errors
I am trying to set up an ssh server on my Debian squeeze box so that I can access it remotely when I'm not at home. I connect to the internet through an at&t 2wire modem/router. First off, I *can* ssh into the machine from inside the local network, e.g.
[Code]...
Nmap done: 1 IP address (1 host up) scanned in 2.12 seconds Playing around with Nmap, I also found that it only sees port 50001 as open.
Something is wrong with the networking on this Ubuntu system. It has been assigned the LAN ip address 10.1.10.10 From another Ubuntu desktop, I can: ssh myself@10.1.10.10 ( from 10.1.10.143 ) and I can login without any problems. I can ping 10.1.10.10 ( from 10.1.10.143 )
I'm using Kubuntu 9.10, my pppd version is 2.4.5 and pptp is 1.7.2 I'm trying to connect to the iPredator VPN service, but I keep running into problems with LCP. I've tried using knetworkmanager, nm-applet, kvpnc and plain old text-based configuration to no avail. Here's a snippet of pppd's output:
[Code].....
(I've got "defaultroute" in my /etc/ppp/peers/ipred config file.) Any ideas what could be causing this? Could it even be my router? It claims to support PPTP, but considering it claims a lot of other things which aren't true, I wouldn't be surprised if it was the culprit.
when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes
i need help to create a PPPoE Connection ( Breoadband)using RHEL 5 cz my ISP use this type of connection .Plz if there is someone can show me the procedure step by step.
im on node1 when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss
ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes -all wired connection over a switch
I am running debian 8 stable version (which I starting to think not that "Stable") and when i surf web pages its ok except the fact that I am too often get connection timeouts then i need to press "enter" in the ur box to try again and then its maybe work if not I am going to press another "enter" on the url box until i have connection to the site its important to say its not a isp or hardware problem. I run the web with no problems in that other operating system which I am not getting back to.....
I am using samba 3.0 on rhel-4, it works fine i am getting the share folder in linux and windows xp as well with username and password for first time only then for next time it will not ask me the username and password for samba user. Actually i want to fix idle-timeout and password authentication for user every time the user want to access the samba share folder.
I have a box running Fedora 14 upstairs and I've been trying to get it to run VNC server, unsuccessfully. I've RTFM, and followed the instructions step-by-step, but it still won't run. I'm getting no error messages. But when I try to connect from either a Window or Mac client, it either get a timeout or connection refused. I've read and tried all the troubleshooting; been working on this for about 12 hours now. Is there something major that I could be overlooking?

I am trying to stream video from my Fedora 12 server to my XBox 360 via uShare 1.1a. I have opened the port I have specified in the ushare.conf file and in verbose mode, uShare sees every video I want to share. The XBox sees the uShare under "Computer", but I get a connection timeout when trying to connect to it. /var/log/messages shows no errors with uShare. I can connect to the uShare web interface without any problems. Most people seem to be using uShare with Ubuntu,
nm-applet timeout. I connect to the internet via wifi access. I have this problem that whenever there is a powercut, my wifi router switches off and then nm-applet tries to connect and then after sometime times out i.e. nm-applet gives up on trying to restore the connection.
I want nm-applet to keep trying to restore the connection indefinitely because if the electricity is back lets say after an hour then it should immediately connect without manual intervention.
I did google around trying to search for the configuration parameters but was not able to do so.
I have a windows 7 box and a debian 5.0 box connected to a linksys wrt300n router. I can access the linux box from windows 7 through ssh. I used to be able to access the linux box from outside the LAN, but when I was messing with the ssh port configuration (at least I think this was what happened), i lost my ability to connect. I tried writing a new sshd_config file so that it is much simpler:
Protocol 2 PasswordAuthentication no UsePAM yes
I tried directly connecting the linux box to the internet to rule out a router firewall issue that i was missing. iptables -L yields nothing, as I have since rebooted the machine since messing with iptables rules. But still, when I try to ssh in from outside the LAN, I get a connection timeout error after a 10-15 second hang.
A few weeks ago, I upgraded one of our machines to the 64-bit server edition of 10.04. All went reasonably well (after some hoops to get it to properly recognize/mount the RAID + LVM partitions), but one of the things that confounded the installation process was login timeouts. From doing some research, I thought I'd gotten it solved by removing the checks for updated packages on login, but I either didn't get it done, or there's something else going on here.The issue is that the machine is headless and is actually a file & application server, but I do need to connect to it via ssh on a regular basis. However, the issue isn't related to SSH, as it also happens when I try and log in through the physical console too.
What happens is that every so often, login attempts will time out for a period of minutes, then they will suddenly start working again, instantly giving me my expected shell. Again, I suspect it is something with the way the motd junk is being generated, but having a server that prevents you from logging in is totally unacceptable. I've no idea how to go about debugging what happens because I don't see anything useful in any of the logs, and I don't have a way to trace the login process from outside. I'd love to hear what the problem actually is and how to prevent this from happening.
I've configured the RADIUS to use a PostgreSQL DB for accounting. Everything works fine if the connection from the RAD to the SQL is OK. If the PostgreSQL service dead, the RAD will skip the failed connection and continue to work. That's OK, too. But if I shutdown the network interface of the SQL (simulating a connection lost - timeout problem), the RAD thread which processes accounting request will be hung up, remains as active and unresponsive forever. So the RAD will not return anything to accounting client (my NAS).
As more accounting requests come, spare threads for processing the requests will reduce and be used up eventually. I've debugged for a while and found it's the problem of PQexec() function. The function blocks the thread eternally till if the connection lost. I know the RAD version is a little outdated, but I cannot replace it right now. I wonder if there's a way to make the RAD reply to the NAS even when the connection between the RAD and the SQL lost.
I have a Debian VPS running Lenny and I'm trying to setup a way to run remote desktop sessions from it. I went with FreeNX, NX client for windows from nomachine, XDM and xfce4. All seems to have installed well, but I can't start an NX session on my box. I can connect to the server and authenticate, but the client hangs on "Downloading the session information," eventually timing out. The log output is below - I'm not even seeing an error message. Any ideas?
[Code]...
The only thing I noticed during install, which was about 400 packages since this was a barebones VPS, was that I should consider recompiling the kernel with CONFIG_SOFTWARE_SUSPEND=y. I don't know if this has any impact on session information, however, since this is a new session, not one I'm trying to resume.
I set the default os to boot as windows 7 with a timeout of 1 second. I thought that this would be enough time to switch os ubuntu when i need to, but I am unable to. How can i reset the timeout to 3 seconds? I also cannot view the ubuntu partition within windows because of ubuntu's file system.
I'd like to buy an USB 2.0 external sound card It's not a multichannel-sorround, It would be just a 2-channel-stereo sound card that converts the USB signal in others digital audio signals (electric and/or optical) so that someone can connect their Hi-Fi or DVDplayer to their computers.
So... In particular, it would be a digital USB-to-SPDIF 24bit/96KHz and USB-to-AESEBU interface. I can tell you that similar USB 1.1 (16bit/48KHz) devices work all with Linux also. I'm not that sure about USB 2.0 interfaces. I know that ALSA drivers go up to 24bit/96KHz and that for sure some of these devices work with Linux also, but I can't tell anything about many others. These interfaces work with MacOSX, no-driver-required. QUESTION: is it true that every audio interface that works on MacOSX without requiring any additional driver, will work also on Linux for sure? I was told so once, by a friend of mine.
I'm trying to get granular with TCP, one of the answers I can't seem to find is. When a client server connection is lost without closing, how many duplicate ack's are sent until the session is closed. I've kind of figured out the the sender will continue to retransmit a segment for about 9 mins if not Ack'd. going from 1.5,3,6,12,24,48 and the continuing with 64 seconds up to around 9 minutes before is resets the session. but whats happening at the other end.?
I have a named server that has forwarders setup. Quite often the dns server where I forward would not respond right away and the query would fail. It would then also cache the empty result for 3 hours and I would need to restart the service or clear the cache. how would I be able to specify a value for forwarders timeout, just like on Windows DNS.
I have centos 5.3 server and the problem is the ssh timeout time set to 10 minutes of inactivity. I want to set the timeout to 1 hour, how can I set the timeout time?
Ive just downloaded Ubuntu 10.10 Desktop to my Mac OSX 10.5.8. it comes to things like "development", "java", "hosting", etc. I downloaded ubuntu 10.10 desktop from ubuntu web site, & thot i followed all the steps that were stated, including the burning to disc, but it wont reboot into Ubuntu. I hav 2 manually choose mac hd even tho it also givs me the option to open with windows or windows disc. But everytime i do n e thing besides "mac hd" it freezes up. BUT...i also am NO pro @ this stuff. N e help is always much obliged. I will also show attachment of the things ive dun, downloaded, installed, burned, etc, etc..for this project.
My spouse bought me a Seagate BlackArmor NAS 110 recently, and I finally had time to connect it to our home network. I have samba installed, and my linux box (opensuse 11.1) can see the NAS, but when I try to open the network connection I get a "timeout on server" message. I bumped up the network connections, but still no luck. The odd thing is that last night I was able to connect and see the public folders for awhile. And her Windows Vista computer seems to connect without a problem after using the seagate software.
I'm no network admin, and have exhausted my resources on this.
I installed linux 2010 mandriva on a (embeded) system,and i run several server programs on it that accept connections from clients. clients are connected to server(s) and every things is ok, but when i go to home and back to my work tomorrow, i see no data can be sent to server programs and this problem exists until i restart the server programs or reconnect tcp client programs. this problem occurs even when both client and server programs executed on the same (embeded) system.why this happens? i checked by netstat and see that server ports exists in the list(and not closed by kernel) but it seems kernel or an application above it prohibit data transmission.i changed the OS and installed ubuntu but the problem exists.
My local area network is always time out for few seconds.I have check my memory with "free -m"There are still left 200+ mb left.I am hosting my own ubuntu server, and I share the same internet line with my server and pc. when I access to LAN, I need to type 192.168.2.2, at outside I can access to [URL]It is only the LAN access timeout, but when I access at outside, I didn't face this problem at all.
I am experiencing horrible name resolution problems in Maverick. I believe this problem is related to having the following line in nsswitch.conf:hosts: files wins dnsI do use Samba and access windows shares in my network (that's why wins precedes dns. I was wondering if there is any way to setup a wins lookup timeout so it can fail quickly enough to try to perform the lookup using dns.
