Software :: Clients Cannot Find Network Scanner?

Feb 5, 2009

I currently have a network with an older machine, which is (usually) operated in headless mode as a data & backup server, with a fixed IP of 192.168.0.10. I have two client machines, a desktop & a laptop, which use DHCP. All three computers are running Slackware-12.2, the clients with a full install & the server without any X components. I want to set the server to serve a scanner & have been following this link, which is mostly a rewrite of the man page for sane.d. I set up saned per the article, adding the saned:saned user. 'scanimage -L' works for both root & my local user on the server. I can ssh into the server as my desktop user & 'scanimage -L' works. Ditto if I ssh into the server, then 'su -' to root. I can scan either locally from the server or via ssh from the desktop machine. BUT, I cannot get the scanner recognized on the network. On the server, I have this line in /etc/sane.d/saned.conf:

Code:

192.168.0.0/24 this line in /etc/services:

Code:

sane-port 6566/tcp #SANE network scanner daemon & this line in /etc/inetc.conf:

Code:

sane-port stream tcp nowait saned:saned /usr/sbin/saned saned

I have changed the line in /etc/sane.d/saned.conf to just "+", for testing. That didn't work either. On the clients, I have these two uncommented lines in /etc/sane.d/net.conf:

[code]....

My server user is in the same groups, less vboxusers. The server is identified in /etc/hosts & I can connect to it via ssh & mount nfs shares from it. What am I (not) doing that is killing network scanning?

Ubuntu Networking :: Find Out More About A MAC Address In My DHCP Clients

Mar 8, 2011

I don't really have a reason for this currently. I recognize all the MAC address on my DHCP client list and keep it rather well locked down. I was just wondering if there was something I could run on the terminal to get more information on a given MAC address on my network. Something kind of like whois for websites.

Software :: Kerberos Clients Cannot Find Administrative Server Through DNS

Jun 27, 2010

This problem has taken me the whole Sunday and the only thing I've got left before start kicking my computer equipment is to ask you guys for help.I have a problem on my client side of Kerberos. Basically, none of my clients is able to make a connection to kadmin using DNS SRV-records. Only if I use the relevant directives in the krb5.conf files - it works.

Something is weird regarding the adm server. I mean, without [realms] stanza, the client does query the DNS properly for the KDC master - it can be tracked in the DNS logs and I mean, even logically - with no [realms] stanza - there is no other place than DNS where it can find this information. So, the actual authentication of the principal works. It's the kadmin-part that exits with the error message above. According to all manuals, books, guides I've read - this shouldn't be happening. The [libdefaults] with default_realm defined in krb5.conf in combination with proper DNS records, should be everything kerberos client needs. But apparently not.I don't remember having any problems like this before. This is the first time in several months a freshly install a KDC. I believe Kerberos packages did get updated few times since then. Could this be a bug of some kind introduced in never version of libs? I have the latest packages on centos 5.3.

Fedora :: Unable To Find Matching CELT Codecs With Other Clients?

Jan 26, 2011

Each time I connect to a Mumble server, this appears:Quote: Unable to find matching CELT codecs with other clients. You will not be able to talk to all users. Apparently that is the cause for not being able to hold a conversation on mumble. Nobody can hear me, though I can't specify if I can hear others at the moment. Some googling has led me to this:

Gentoo Bug #293300
media-sound/mumble-1.2.0_beta1 tries to load media-libs/celt-0.7.0 as
"libcelt.so.0.7.0", but the actually installed library is named
"libcelt.so.0.0.0". Thus CELT support in Mumble is supposedly missing, but can
be restored by symlinking libcelt.so.0.7.0 to libcelt.so.0.0.0.

General :: Are There Any Windows Tabbed SSH Clients?

Sep 4, 2011

I've been using PUTTY to connect to several Linux-based development boxes via SSH on Windows. However, I'm often in a situation where I need several such windows open at a time. I'd like to be able to put these into a tabbed window, similar to how a web browser works. When I'm on a Linux box I just open gnome-terminal with several tabs and start several ssh sessions in different tabs there; but on Windows something like that is obviously not an option.

General :: Proxy Server Not Responding To Clients?

Nov 15, 2010

I have deployed proxy server in my office about a month ago. I have about 7-8 client accessing it through port 3128. After some days of deployment, my server started creating problems. Some clients were not able to access proxy while other clients were accessing it. The error message which I found in cache.log was:

Code:
WARNING: Closing client 192.168.2.99 connection due to lifetime timeout

In this way it was disconnecting clients randomly. The problem resolves when I restart proxy server

Im sending my cache.log file

General :: Windows Clients Not Using NTP Server Provided Via DHCP?

May 31, 2010

I have a network consisting mostly of Windows Vista and 7 clients and an Ubuntu server. The server provides both the DHCP and NTP services through dhcp3-server and openntpd. In my dhcpd.conf, the subnet is declared as follows:

subnet 10.10.10.0 netmask 255.255.255.0 {
range 10.10.10.10 10.10.10.200;
option broadcast-address 10.10.10.255;
option routers 10.10.10.1;
option ntp-servers 10.10.10.1;

The clients don't seem to be using the NTP server though. When I capture the network traffic with Wireshark during the DHCP process, I also see no mention of the NTP option in the DHCP offer message. I am not quite sure if the clients would have to specifically request that option to receive it or if I have to make another configuration to offer the option.

General :: Iptables Rules To Allow Nfs Clients Access To Nfs Server?

Jan 20, 2011

I'm curious but recently I was troubleshooting some iptables rules to allow nfs clients access to my nfs server. What was strange was that I setup a tcpdump session on my nfs server so that I can see which ports were being requested. I ran several tcpdump sessions with the following filters in place.

tcpdump -vv src ip_of_client and dst _ip_of_client
tcpdump -vv src hostname_of_client and dst hostname_of_client

However, the only packet I ever saw come over the wire to me was the client host asking for a arp resolution. Anyhow, I finally just ran 'rcpinfo -p' and added those ports to my iptables rules and it worked great. However, I would like to understand how nfs works in case I need to troubleshoot it in the future. I do understand that nfs uses portmappers, would this explain the behavior?

General :: New Windows Xp Clients Can't Join Samba Domain / Fix It?

Aug 18, 2010

We've been running samba on linux for a while and everything was fine. All of a sudden when you add new clients to the domain you get the error message :Logon Failure:unknown user name or bad password. This to me seems like a windows error message and not a samba error. When you remove an existing machine (ie on domain) and then try to rejoin it to the domain you fail.

General :: PPPOE Server Access Internet Clients Fail To Access Internet

Aug 26, 2010

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.

On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.

The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?
