新装的slackware上不了网

GavinLan · 发表于 2007-2-2 01:52:36

系统装好后，发现上不了网，用ping ping了一下本机的IP就通，但ping其他ip、网关等，都显示：“Destination Host Unreachable”。用SSH服务也是这样，即到本机ip行，其他ip都不行。IP地址、掩码、网关、DNS在安装过程中是确认填写正确的。
在安装过程中，到安装modem那步时，即：

选了/dev/ttys4，即PCI接口。而我的网线接在主板自带的网卡接口上。不知这是否有影响？

另外，在到配置系统服务的那一步时，即：
http://www.linuxsir.cn/bbs/attac ... 33&d=1069842831

我把rc.pcmcia、rc.sendmail两个服务去掉了，其他默认的留下，这是否有影响？

你用的adsl还是modem拨号上网？

我用的是ADSL，几台电脑连接到一个交换机，然后交换机连到ADSL Modem。系统是Slackware 11.0。之前我在自己台机器安装是没有这种问题的，但现在在另一台机器上(同一个局域网)就有这种问题。差别是我台机是IDE硬盘，独立网卡；现在这台机是sata硬盘，集成网卡。

IP地址，网关这些看看设置对了么

d4rkl0rd · 发表于 2007-2-2 13:49:11

用dhcpd

试试把交换机的IP地址用route命令添加到路由表中

euler · 发表于 2007-2-3 12:47:51

对，把路由的地址或者dns的地址加到/etc/resolv.conf文件中

试过了，还是不行！
我在开机的过程，仔细的留意过启动过的东西，发现以下的一些信息:
在slackware启动过程，有以下字样：

eth0: link down

复制代码

后面还有：

cardmgr[134]: no pcmcia driver in /proc/devices
/etc/rc.d/rc.inet1: line 1: eth_up: command not found
/etc/rc.d/rc.inet1: line 2: eth_up: command not found
/etc/rc.d/rc.inet1: line 256: eth_up: command not found
Scanning all LUNs for additional hardware: /sbin/rescan-scsi-bus-l

复制代码

进去系统后，我编辑了：/etc/rc.d/rc.inet1文件，去掉了所有“eth_up”，上面代码中的：

/etc/rc.d/rc.inet1: line 1: eth_up: command not found
/etc/rc.d/rc.inet1: line 2: eth_up: command not found
/etc/rc.d/rc.inet1: line 256: eth_up: command not found

复制代码

就再没有出现了，但是还是不行，ping不通网关、非本机IP的问题依然存在。
注：编辑/etc/rc.d/rc.inet1文件时，发现在

#! /bin/sh

复制代码

语句前出现了4个"eth_up"命令，即如下：

[indent]eth_up
eth_up
eth_up
eth_up[/indent]
#! /bin/sh

复制代码

ifconfig 先看下网卡能认出来么

然后贴你的IP地址、掩码、网关、DNS出来看看

猫开了路由功能后，比如说猫的IP地址为192.168.1.1，你本机的网关设成192.168.1.1，IP地址192.168.1.100等等。。。

# When using IPv4 packet forwarding, you will also get the
# rp_filter, which automatically rejects incoming packets if the
# routing table entry for their source address doesn't match the
# network interface they're arriving on. This has security
# advantages because it prevents the so-called IP spoofing,
# however it can pose problems if you use asymmetric routing
# (packets from you to a host take a different path than packets
# from that host to you) or if you operate a non-routing host
# which has several IP addresses on different interfaces. To
# turn rp_filter off, uncomment the lines below:
#if [ -r /proc/sys/net/ipv4/conf/all/rp_filter ]; then
# echo "Disabling rp_filter."
# echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
#fi
}
# Stop IP packet forwarding:
ip_forward_stop() {
if [ -f /proc/sys/net/ipv4/ip_forward ]; then
echo "Disabling IPv4 packet forwarding."
echo 0 > /proc/sys/net/ipv4/ip_forward
fi

# Restart IP packet forwarding:
ip_forward_restart() {
ip_forward_stop

ip_forward_start
